How to Stop Damp Penetrating Brickwork
HTML-код
- Опубликовано: 4 май 2020
- Waterproof your brick walls with Stormdry, a colourless, breathable, water-repellent treatment for brick, concrete and stone walls. It's a deep penetrating cream that is applied to the wall surface using a roller or brush. Once Stormdry has been applied to the wall surface in a single coat and will permeate deeply before curing to form a water-repellent barrier for a BBA approved 25 years.
Typical applications for Stormdry include:
Protecting against penetrating damp (rain penetration)
Improving the thermal resistance of masonry by keeping it dry - verified by the Energy Saving Trust
Improving the performance of cavity wall insulation by protecting it from moisture
Improving flood resistance of masonry
Breathable and Long Lasting
Stormdry is based on carefully selected silanes and siloxanes which line the pores of the masonry to form a water-repellent silicone matrix. Because it works by lining the pores rather than blocking them the masonry is allowed to breathe and does not suffer from increased frost damage (spalling). Due to its novel formulation and deep penetration, Stormdry is resistant to UV light and other forms of degradation, resulting in a life expectancy of 20 - 30 years.
Deeply Penetrating
Stormdry is able to penetrate more deeply into masonry than traditional liquid-applied masonry water repellents. As well as increasing life expectancy this also improves Stormdry’s crack-bridging ability. As the diagram to the right shows, Stormdry is able to provide water-repellency beyond the depth of small cracks.
It should be noted that larger cracks will still need to be filled as part of the Stormdry treatment. Mortar lines may need to be repointed with a sand/cement or sand/lime mix incorporating Stormdry Repointing Additive.
Effective
Stormdry has been tested to BS EN ISO 15148:2002 (E), demonstrating its effectiveness on concrete, mortar, brick, and sandstone. The graph below shows that the water uptake for Stormdry treated samples was considerably lower than for untreated samples:
As Stormdry is formulated to penetrate deeply into masonry it can take up to two months after application for a noticeable “beading effect” to appear when rainfall strikes the wall. However, Stormdry is resistant to rain after just 12 hours.

Keep up the good work Roger, there is no end to how much people can add to their skill and knowledge base, and lets face it, its in short supply at times. Builders need to be encouraged to engage their brains more as well, is the greatest gift we've all been given as well as working on fair levels of disclosure.
I have a 150 year old cottage built from Norfolk reds, I have many problems with penetrating damp. This is absolutely fantastic, thanks Rodge, always watching this Chanel for the best tips and tricks. Keep up the good work!
This is the perfect product for those old red rubbers
Have used this product i had cavity wall insulation which had broken down allowing penetrating damp instead of spending 6k to have it removed I used this product, it worked brilliantly if you throw water at the wall it beads off and does not penetrate although it is expensive £120 for 5 L but it is BBA approved and is warranted to last at least 25 years good vid as always Roger
Such a great tip on the moisture creating an electrical issue. Thank you.
Roger.....you have the patience of a Saint! I cannot believe some of the attitude on display here!
Nearly everyone who comments says the same thing. "The walls can't breathe" . All the independent test by laboratories all over the world have found that this product has a high level of vapour permeability. It cannot trap moisture but it stops moisture entering the wall so the net result is a much drier wall. I have had so many people contacting Skill Builder to say that they used it after seeing the video and it solved their damp problem in a matter of a few days. So the difference is between those who have never used it but seem to know all about it and those who have used it and know one thing.
I've had a problem of water penetrating the roof space. The builder decided after doing everything that the bricks were porous on our 1820 chimney. Rain was soaking into the bricks and exiting in the roof where a wooden beam touched it. Stormdry24 absolutely solved the issue 100% ... It really is amazing stuff. It's meant to last 25 years with one coat. I gave it two anyway as I might as well use up the 3 litre tub. It's expensive at £80 , but as the builders and scaffolding costing me £1300 its dead cheap.
Ps yes I too noticed the cement pointing rather than lime mortar on the video. Who the heck does that!
I used a similar product on a Victorian house more than 20 years ago and the problem is still solved. Amazing stuff. It also stopped the brick surface weathering. I just wish more people understood how good it is and stopped wasting so much money on avoidable scaffolding and brickwork or ineffective internal replastering.
Hi what was the product you used please.
All your videos that I watched so far have been very informative and helpful. Thank you
Good old boy,it’s good to see a practical professional.x
Where can I purchase Storm Dry?
Fantastic videos you post here, I watch every one. I only wish I could find builders as good as you lot. My last builders were so crap I had to undo what they did and ended up doing it myself, with help from RUclips videos like this. One guy invoiced me £5000 for some steels which I found out cost him £500!!! Beware of builder's trying to rip you off! Or like me never trust anyone again and do it yourself.
Well I never!!
I would never have found that fault!! Genius 👍😊
About six years ago I had water coming in round two windows. I replaced several bricks that were spalled, did some re pointing and sealed round the windows with CT1. Still the water was getting in so I did some research and found Stormdry. It is very expensive, I think it cost me around £300 to do the whole side of my house. I did it myself in a few hours and really pleased to say it does work. I would definitely recommend it.
Is it breathable?
Any issues with the condensation or damp?
@@Ajklens It is vapour permeable and will not lock in moisture. It lines the capillaries to stop the mortar soaking the water. The water flows out much better because it doesn't clog.
@@SkillBuilder Is this true if our walls have no vapor barrier? Our brick house is brick and cinderblock, with plaster walls and no cavity. The dampness is real! 😞
@@SheenaRea same here🤔
Great video thanks, in the UK moisture and damp id a major issue, every house uve been in there have been some small damp problems, so i really eant to increase my knowledge on damp, so please upload as many damp educational videos as posible. Cheers
I watched your video very useful. I am try to search for all your video lesson. Thank you so much!
I have used silicone based liquid to waterproof brickwork on chimneys, roof tiles and below dpc. There are 2 types: water and spirit based. The water based was a pain to get on as you had to work to get the brick 'wetted'. The spirit based went in like blotting paper so I always use that. Your product looks very interesting
Just spray on with a spray Bottle works every time
This builder is amazing so much knowledge respect to him 👏
i have worked with with these products for 7 years now.. its actually what they class as nano technology. Once applied onto brickwork or stonework the nano particles sink into the substrate and provide a protective barrier.. aswell as not allowing water to penetrate it also provides thermal efficiency, brethability and also is self cleaning due to the moisture repelling properties in the product. Awesome product.
Just used some on part of my wall on a similar property. I have quite a few spalled bricks so hoping it will give them a bit more protection.
My brick house is 75 years old and there's no insulation, just cinderblock behind them, and plaster walls. Will this product help keep the damp out? One commenter said this traps moisture if there's no vapor barrier. Do you know, Capt. Sparrow? Thanks.

What’s the American version of this? All my rentals are over 100 year old brick row homes
Just wondering if my dryer vent could be causing the damp brickwork, as the bricks are damp near the dryer vent and nowhere else around the house?
Love your vids Rodger, im about to get my 1850s house repointed, nightmare for cost!
Nice one Roger , I could do with this stuff for our new build single skin garage ready for the autumn . I will give it a try 🧱🧱👌🏼👍🏼
Did you try it? Got a similar problem with single skin garage
Such a great channel! Always so informative and helpful. I was wondering, what is the best way to clean the bricks prior to application?
Thank you Roger ... We've moved to the UK from Western Canada and I have a big learning curve. In learning about our brick home!
You are a man I can trust , I get that feeling from the few videos I've watched already.
Many thanks.
Rob Stapleton
Thank you Roger great video carry on.
Very good, I have a brick built bungalow and the course below the DPC are not engineering bricks and seem to absorb water. The walls are cavity with a injected cavity wall insulation the damp is visible above the DPC and know what brickies are like the will be a lot of mortar down at the base of the cavity which gets damp and transmits the damp through to the inner leaf of thermal blocks. This video has just introduced a fix from sorting out the problem before it becomes a larger issue.
I had same issue, bridging,,cut brick's out there was some rubble in cavity which on that 1937 house was only 40/50 mm.
I injected cream DPC seemed to solve. Now in a 1958 house needs full repointing.
Thank you Roger, excellent bit of info.
Fantastic! I've been fighting damp in my Victorian house and have been losing! Will be trying this!! Thank for the video!!
Can't speak highly enough about storm dry. It still allowed my lovely old stone home to breath but kept the water out.
Great video as usual
Am watching your help videos on Rising Damp and DPC and they are both interesting and very helpful. My intention to put in a DPC in the warmer months so I'll obviously refer to them again.Thanks for all your help and advice. Greatly appreciated.
Very informative, fantastic thanks
Great video Skill Builder team. 👍👍👍👍👍👍👍👍
Thank you! I am going to do that!
Perfect. Thank you.
Thank you for doing this . 👍
My trouble is direct penetration through a building stone (mortar-plastered inside and out) wall 2'4" thick. Inside you can see a damp patch radiating out for about 2' diameter. It surrounds a double socket that's used occasionally. There are some structural cracks on outside wall growing from the window lintels. I was afraid that water could have got into these, froze during a recent icy spell and forced more space during the ice's expansion. I can switch off a circuit-breaker controlling the sockets near the damp patch. But how does a fella fix the damp getting in ?
Great advice Roger! Thanks for sharing. Cheers.
Excellent product for chimneys. We use it all the time, well worth the money.
I have used it on chimneys and it seems to be a lot better than the Thompson's silicone which drives out after a few years.
I have a damp chimney in the loft over the dpc tray, the bricks and mortar are wet above the dpc tray in the loft. Do you think the stack above the roofline is soaking the rain in then falling down to the dpc tray before wicking back out in the loft?
Great product👍
I have used on loads of houses they have different product wich are great worth the price.
Hi, our outside wall is double bricked if we use the Stormdry product how will the internal wall dry out also will it need to breath inside in order for the damp to disperse
Can I paint this over masonry paint or must it be on bare brick?
Just ordered some off the back of this video. Bit of a scary price but i trust your reccomendation!
Gringo Tom
It is expensive but it does work. Everyone who uses it says the same thing.
@@SkillBuilder is agree totally, please see my reviews above. I spent hundreds on this but if it last 25 years it's cheap as chips
I have missing render ans water has been making the wall wet, and my inside wall. Should i put this on before the render? Or can i get away without the rendering. Im being quoted prices i cant afford, so have to be a big girl and do it myself.
If used correctly this is a fantastic product, especially regarding penetrating damp issues on cavity walls :)
i don't agree with the claim that is stops rain penetrating yet still allows the wall to breath, no product on earth does that, not human skin nor gortex, nothing
@hopclang9409 How do you find human skin performs as a building ma....... WHAT ???
who, I mean, what? & it breathes !
Watch Goldfinger for fiction based proof of this otherwise reasonably well known fact.
Brilliant, thank you for bringing it to my attention. I too have a grade 2 listed building and this summer I will be using this product.
You made this comment 2 years ago... did you use it?
I’ve discovered that the damp we talked about, is a rain ingress issue, ear to the wall, you can hear heavy dripping in the cavity. Have zero clue how. Have done 7 jobs so far, ridge
tiles, new felt, silicon,
sandtex, not made any difference, rain causes the constant dripping noise. At a total loss. Going to try to a tarpaulin experiment, covering each
area of the roof, gutters, old kitchen chimney. If that doesn’t id the source, I’m knocking the house down and buying a tent😭😭❤️
great video. Ive just built a house and realised the bricks and mortar are very pourious .im considering coating the south east wall in stormdry. many building friends warn me against doing this as the brickwork is less than a year old and needs to weather.
my questions are -
1. is this a good idea on a new build?
2. does the wall need to be dry for application of this product ?
3. is product water or spirit bassed?
thanks for any replys
Good vid and advice
What would you recommend to seal internal brickwork to stop dust
Hello, can this be applied in the winter months? as the walls may be more damp at this time of year. Thanks for any answers. Also can I use a roller to reach higher, or should it be applied with a brush?
Thank you so much
You have just told me what's wrong with my wall !!!
Can you apply StormDry on top of wet bricks??
How do you dry wet bricks quickly?
Hi Roger, ive got thick thick moss growing between my bricks on my rear house wall. I've scrapped some off but you can never remove all the spores and i can see it developing again 6 months later. What do you reckon would be a permanent solution?. Have a builder remove and repoint all my bricks or apply some sort of solution to let it die, remove, repoint and use stormdry as a sealer? ps my house is 10 years old, was a new build and is a single brick skin over a timber framed substructure..cheers
Might seem a daft question but should I point up my brickwork first before application and I'm guessing it's OK to paint the brickwork after it's dried?
Hi.. is it recommended to use this product on internal garage walls that are suffering from water penetration from higher ground on the outside or is this more for external walls to stop rain ingres??
Thanks
Hi Roger lovely rewarding video. Just wanted to kindly ask you if I can use this storm dry on external block work. Or what do you recommend. The pea shingle set on render has blown away and become brittle so the rain is penetrating through to the internal kitchen wall. Some advise would be much appreciated,
Kind regards,
Saj,
London.
Sweeeet …Thanks Roger 👊
SB, if you have a solid brick Pot brick, walls with no cavity what is the best method to insulate the property, internal
Or External, if the outer walls have rendered masonary and the property is a terrace property, with minimal signs of condensation.
Would weather proofing cream being applied to external walls be enough?
Hi I have a new shed built with cavity blocks. Plastered on the outside and skimmed on the inside. During heavy rain one bottom corner inside gets wet. Seems to be right in the very corner and spreads according to the amount of rain. No sign of damage on outside. Really worried about this,do you have and suggestions why this might be happening or better still a cure. Thanks
Can you apply this to internal walls before you put the insulation in?
For example, apply this to the inside walls then put insulation and then plasterboard?
Hi roger.. great tip!
Can you paint on top of this stuff?
Thanks for advise
Will this prevent brick and mortar from Shedding Dust? I was thinking to use it indoor for the chimney
Please can you tell me if there is any similar product that can be used to do the same job on a wall built of Blocks, rendered then painted or is this not possible?
Can this be used on pebble dash, I have a corner on my house just under the gutter that always looks wetter than the rest of the house.
Some penetrating damp appeared in the corner of the bedroom on the inside, I cleaned the guttering out and replaced the corner, it has dried out but sometimes still feels a tiny bit damp.Could this be a solution.
I would appreciate any advice.
Thanks in advance.
Hi! This is really very informative.
I live in a 140-year old cottage bungalow. Everytime there is heavy rain, there is a leak coming into the chimney although it has been closed off from the top and bottom fitted with a vent. We had 5 roofers who have looked into the problem but no one has yet solved the issue. It has costed money! Is it worth using this product around the chimney bricks? I would reallh appreciate any help as this has caused us so much stress.
Hi, my daughter's house has recently had outside cladding fitted (looks very nice). Builder said to use bitumen on the bottom (uncladded) bricks all along the house. Would Stormseal be a better option? House is solid walled (very old). And can I use Storm seal in the cellar?
I have used thompson wall sealant on my brickwork so when it rains the water beads away
Hi, useful video, thanks. How many litres would you need for a gable end of a terraced house that’s roughly 45 square metres? Would one 20L tub be enough?
We had paint peeling around sockets on outrigger wall, removed socket face plate and found water seeping from wall into the socket box! Will Stormdry work if the pointing is patchy, or do I need to completely repoint first?
Hello love your videos . I used the abacus board to do my bathroom fantastic stuff . In relation to this water profer I have solid walls on my bungalow with horrible pebble dash which in future I’d like to have silicon render out on would this stop the rendering adhering properly or it it ok to use ? Any advice would be fantastic 👍
Great video Roger thanks Stay Safe
Thanks Michael you too!
Excuse my ignorance but what do you gain from applying this to a chimney?
If the brick was primed and painted will that waterproof it?
And if not Can I use this product over brick work that was recently primed and painted? It has 68 year old Spalling bricks. just like on this wall; looks very similar before it was painted and there was moisture coming through the wall.
Hi Roger if you splash water on the treated wall will it soak through or it just repels it?
In other words is the waterproof effect on the surface of the brick or just on the inside/internal side of the brick ?
Thank you guys
Interesting product, could be useful in some situations, especially in money saving situations. The real crux here seems to be that this grade 2 building was clearly originally lime pointed, you can see it in the b roll shot and at the front where the pointing has failed, has been pointed with cement. Get that off, repoint with lime and the failure of the bricks will be greatly reduced, moisture escaping that wall will be using the bricks causing deterioration as the cement is to impervious.
Yeah, thought that myself, looks like almost pure cement pointing
@Gazr Gazr im doing a lime mortar pointing job in may off scaffold, the client wants it done in cement and sand for cheaper and in a week ...ive given him the bad news ..a big fat no and no
I’ve also read that stormdry May slightly waterproof the wall from the outside for a time, but it stops the wall breathing and allowing it to release moisture from within. This usually can cause more damp problems?
Does anyone support that statement? And should it be avoided on old buildings?
@@AmateurCaptain I'd like to know this too.
I’m definitely not a bricklayer lol can you do cement and lime mortar? With soft building sand like a 4.1.1 ?
I have this issue in my bathroom. So you wouldn't recommend replacing some bricks pointing up waiting for it to dry out and then apply the storm dry?
Is this for old bricks or can you use it on new bricks in a cavity wall
Can you use it on the inside of a rendered garage wall to stop water coming in?
Thank you roger for the great video helped me out a lot never heard of stormdry before I’ve brought four tubes for my home to help with damp in some areas of my home and wow it worked a treat for me 1 more sub.
I can’t access the outside wall. Is there a treatment for the inside wall I can apply? Will Storm Dry work from the inside out?
Can you or would you use this on internal walls???
nice work
I coated the wall with Thomson water seal. It's clear and easy to apply. Worked very well.
Be careful with thompsons on an older property as it doen't allow the wall to breathe.
Yes. The house was a 100 years old and the wall had been injected with a new damp course. But the wall remained damp according to surveyors. So I Thompson'd it during a dry spell. Interior had plaster and wall paper the exterior bricks had become porous. Few weeks later new survey and it passed with flying colours.
@@howardbowen-RC-Pilot let us know if it suffers raising damp in the next few years, I don't think Thomson water seal is breathable so it will affect how the bricks dry out. Hopefully you'll be ok, but I wouldn't recommend it especially as you can get breathable alternatives.
@@howardbowen-RC-Pilot how was the bricks? I’ve got similar age house and damp course done, but the bricks are weathered in areas (faces mot great some small holes etc). Was your bricks similar as it seemed to work for you?
How did Thompsons Water Seal work out for you?
I wonder if I could use this on a external painted brick wall??
I sprayed some Ronseal Thompsons Water Seal for my house 5 years back. Those last for a couple of years and its effectiveness seems to reduce over time. from full water repellant to semi repellant but still much better than nothing on which bricks get wet/soaks.
Yes Thompson's does get driven out by rain. The siloxane is a glass like lining of the cappliaries.
I have something similar on an old end terraced house (With no cavity). I've been suggested to get some permaseal to stop the rain from constantly bombarding the gable end. Are there any suggestions from any of you who know what you're doing on if this is the right solution?
Great video. Ive used storm dry a few times now. Great product but pricey. Do you know how Sandtex Brickwork waterproofer compares ?
Beautiful windows on that house!
It is a lovely house.
Indeed, but someone thought PVC down-pipes was acceptable!
Ive been told the best way to deal with chimney salts is to knock all the render off, then spray it with TG500 and use Sika 1 in the mix. Is this right for chimney salts?
Can use product be used on painted concrete mix rendering.Thank you
Will this work on a concrete skeleton building with cinder blocks that is rendered with cement render ? or does the render need to be removed before this is applied !
Hi just watched your video clip I painted my front exterior wall grey special outdoor paint 6 months ago and after few months down it started to stain yellow on some bricks ,how can I get rid of it thankyou
Hi there. I really enjoy your expertise . I sent some photos of my bricks. Before I start sealing and filling in the mortor joints . Is sika ok to use ? I recall some comemts you made about some of these fillers . And only sand and lime mixtures are best .
How do you cure damp like this on a wall that was painted a long time ago?
If I have used a different make before but it is now failing can I still use Stormdry ?
Thank You
Bit of advice
Had a block built 6 x 4m unit built ( while on holiday) on a reinforced concrete pad
Apparently no dpc was put down
It's single skin block, what's or how is it best to move forward as it looks like damp is coming in will the celotex stop this coming through when done, no gutter fitted as yet so they will help
Would you tyvek the outer and then clad ?
Can this be used on pebble dash walls?
Hi Great video. Can you apply stormdry on an old pebbledash wall ?
hi Roger, can you apply storm dry in the winter months?
I have a brick shed that has this problem, can I paint inside the shed with this too.
What do you use to stop the water completely from going thru the brick,?
