Thank you for taking the time to do these lime pointing tutorials. Best I've seen. I'm trying to repoint chimney breast in roof but it seems to dry out very quickly despite misting spraying wall ie dry by next day. Is that really no good? Do I need to redo it and soak wall? Whatever it is though its better than the loose sand thats in joints or missing altogether!
Thank you for the compliment it means alot , Soak the wall before pointing ie with a hose pipe if you can and then after you have repointed it mist it over as often as you possibly can for a minimum of 3 days for this time of year if your pointing in a windy area cover it with a sheet as the breeze will dry it out alot quicker
Hi Glenn, great set of videos and work is great. Can you point me to a video for laying with 3.5 lime please. Ive done some practice walls in yard with a collage hydrated lime mix and found that ok
love your work how long would it be before the hessian sheets can be removed would you keep them on for 5 days and would you wet the wall at all after pointing or just the hessian sheeting
Please feel free to subscribe it helps getting my channel out there Depending on the temperature I would keep it on 5 days dampen the Hessian each day If it's hot the next day if it's gone of hard enough soak it two or three times a day with a hose pipe You want it to slow set The slower it sets the less chance of it cracking and drying out too quick Hope that helps
Thanks so much for all your videos, so much information! I've recently started hacking off the render from my 1900 stone house, some parts have definitely got cement but the majority is like black mortar. Would this have lime in it? We don't have any signs of damp inside the house but render is just so ugly 😝 How soon after replacing the mortar do you normally wait to paint/seal? Have you got any recommendations for cleaners for natural stone? Thanks so much for any info!
Yes it will be lime probably black ash mortar or mixed with soot out of a chimney So you are going to repoint it then you want to lime wash it is that correct?
@@GMTpointingspecialistsltd it's quite soft and hasn't been done the neatest! Fortunately the render hasn't stuck very well to the stone so hasn't done too much damage.

@@GMTpointingspecialistsltd Will that come out like the colour your doing just now using washed Sharp sand.? Ive been pointing granite for years but using cement. Have you any tips for using lime in summer time. Someone wants me to point a house in lime that was built 100s of years ago in North East Scotland. It was all harled but was pointed originally and its patchy with cement and lime from over the years of patch work. Thanks in advance
@zeusricochant7357 I'd use a lafarge or Saint astier nhl2 or 3.5 Talk to the Scottish lime center they might know the area that you are working in If its to hot take the day off or rake out don't point I work under sheets so the wall is in a shadow Plenty of damp hessian and keep soaking the walls before and after you point
Hi, just a quick question, when pointing inside the house, is it also necessary to cover it with a hessian or just mist over it every now and again? Also, in total, how long does it take for the mortar to be completely dry? Thanks!!
You can use Hessian inside it just keeps the wall damper for longer Mist over as often as you can Try and keep misting over for a minimum 3 days or as long as you can You want a slow set
Another really informative video, thabks for these. Two questions from me if i may 1. what does covering really do? Its not going to make any difference to the temperature, but i guess keeps the wind off 2. Is late march too soon to do my re-pointing?
Covering with hessian In the summer stops direct sunlight drying it out to quick In the winter or cold weather Frost freezing rain and wind Clings to hessian rather than the pointing As long as the temperature is staying above freezing overnight its fine I'd still cover for 7 days to prevent frost damage Hope that helps
@@GMTpointingspecialistsltd amazing, thanks so much. Just googled your website, you're based in Buckley, not too far from where I grew up in Ruabon. I'm going to repoint my Mum's house there in the last week of March and am binge watching your videos in advance. I note you're fully booked up for most of 2024. Would you have say 30 mins for a video call for me to run some ideas past you and show you the sandstone itself and whether the existing mortar under the cement render is lime based? I'll pay you for your time of course
what do you think to using hot lime mortar instead of hydraulic lime ? Its a better material...stickier and high compressive strength and needs just knocking up (hammering) and essentially no water to make it workable.
Hi hot lime has its place I'm in north Wales the rain comes sideways So NHL 2 and 3.5 I use most of the time I switch to hot lime if it's a protected area And I can leave the Hessian on longer Compacting it back gives the lime it's strength not just it setting
Hi there. Thanks for the great vid. I need to repoint some internal walls - grade 2 listed yorkshire grit stone farm buildings. Loose limewash (I think) on the inside all crumbling off. Should I use NHL or putty? Outside walls have been pointed already in lime. Any preference of brand too? Would be great if you get a chance to do a vid on internal wall lime pointing. Thanks.

Black dye if it's a cement dye it's no good for lime Google lime supplies Ask them for grey brick dust or a grey colour pigment you can add to lime Wind will dry your lime out really quick so either wait till it's not windy or sheet your scaffolding up But be very careful as there been a few scaffolding jobs collapsing in this wind

Only done the lime last couple of years of 17 years in the game so knowledge appreciated.top work

@bootangy I've done a couple of videos on it About 30 minutes I mix for 10 to 15 minutes dry mix Then when I add water 10 minutes minimum then after I stop mixing I let it sit for 10
Depends how long it's been on the bricks butWater and a rag give it a good rub Or failing that a light acid but if you get acid on your pointing it will change its colour
@@GMTpointingspecialistsltd why soak it mate? I did mine last year first time was great, this year somone else's and cracking must be from sun getting on it can't think of anything else, But mine dried in 8 hours a day max and its not cracked odd, may be tho weak seem ok, ill have to do mine again if i get problems seems ok tho, nhl 3.5 like u and 3:1 I do It's 7pm got home hour ago and now gonna go back to they house and scrape it nooo lol

Thank you, Glenn. As a boy I saw my father make putty for plaster. Some of the RUclips videos are confusing hence my question. I work in construction in the states and everything here is Portland. Very few masons here understand lime mortar let alone use it.
@peterfcoyle9127 yeah a lot of miss information out there but the states have different temperatures to us But I try to make sure people understand that harder doesn't mean better You want to sacrifice the pointing rather than the brick or stone
Here it is all about production. Lime mortar sets too slowly. They want to be on the wall the next day running it up higher. Lime mortar goes up 6-8 lifts and you must wait for carbonation. I mentioned this to a brick ie once and he looked at me like I had two heads.
This is an NHL I'm using so it needs water to set Knocking it back with the churn brush gives it it's strength as it's compacting different shapes of sand together after care is protecting your work from drying out to quick Use Hessian and sheets and mist over with water

Another great video. How many times do you knock it back and is that the last step?
You knock it back till it follows the stone and looks tidy
I should of done a close up
After you do the knocking back put damp hessian over it

Yes lime releases water it wicks away
Cement will lock moisture behind it
