In this video I demonstrate how I set about making Whitewash from quicklime - slaking with water to create a lime putty, which is the basis for the 'Whitewash' paint.
Hi - certainly improved the situation - one of the interior rooms has dry lined walls so difficult to know what’s happening there but the other room where I re-plastered with lime is dry. I have also subsequently drained that back area of the house so it all makes the place dryer. Thanks for your comment. Regards
I suppose you could although it’s a friable loose material which could be a problem inside. An alternative in the breathable paints would be a ‘clay’ paint for the range of colours and ease of use…
Hi - you need quick lime then add water to to make the whitewash. There is a chemical reaction and heat creating the slaked lime. When painted onto the wall it gradually returns to calcium carbonate. Hope that helps..
Hi Owen - I’m not an expert so please seek further guidance from a lime supplier. One comment above suggests using hydrated lime which could be a safer option as it doesn’t involve the slaking (boiling) process. Thanks for watching.
I am in the process of doing this at the moment.. I'd agree that if you don't want to slake lime them get some hydrated lime.. for me I wouldn't use NHL to lime wash..
Hi, just a quick question. How is the lime paint looking now? I have read somewhere that you should leave it to mature before painting for at least a month. Not sure if it makes any difference? Thank you Lenka
Hi Lenka - your question has prompted me to go and have a close look…as far as I can see it’s still looking fresh and bright, other than at the base of the wall where during Winter months there’s a bit of green algae like you get on any hard surface. Tends not to be noticeable in the Summer. Overall I’m very happy with the wall now. I’m sure that leaving the mix for a month won’t do any harm - I wasn’t aware of this but it doesn’t seem to have affected the finish I have here. Best wishes with your Limewash 👍
The recommendation for leaving a lime putty to mature is only needed for when you want the very finest finishes. External finishes won’t likely need that. On top of that, a lime wash applied hot tends to adhere better than cold stuff.
Of course you could use hydrated lime, much safer for those who are accident prone. Also easier to get a hold of. Whem I'm off walking I use a flameless heater that uses that chemical reaction to heat water. The little packets of quicklime are quite expensive, following watching this video i may make some up myself.
That’s interesting - I have a ‘hot’ lime supplier in my area so source materials from there. Certainly a process which requires great care. Thanks for watching and the comment- 👍

Thanks for the video very informative and helpful 👍
Glad it was useful Gerhardt
lovely job, thanks for sharing - nicely informative too
hi youve done a really good job of that wall, did you find all your damp went away?

Is it better to put the lime in the water, or put the water on the lime, have you tried both ways?
Could one use this white wash to paint a newly plastered ceiling (the ceiling is in a moderately dry basement)
I suppose you could although it’s a friable loose material which could be a problem inside. An alternative in the breathable paints would be a ‘clay’ paint for the range of colours and ease of use…
So cool! (Pardon the pun!)
I'm actually having a doubt..
So for white washing we use quick lime Or slaked lime?

hi, just wanted to ask you if I could use NHL 3,5 with water for lime washing rather than lime putty? all the best

The quick lime works much better as the lime stays dissolved and adheres better as well.
Thanks - seems to work very well on the wall I applied it to. Thanks for looking in…

@@georgeharrisadventuresinhealth Hi George - Thanks for that. Mine went on as soon as it was cool enough to be safe to use. Regards
Water ot down and spray it on with your sprayer
Isn’t that how they get acetylene gas ?
Hmm - not sure. I certainly would avoid breathing it if you can!
you really need breathing protection as part of your PPEs
Thankyou - yes, you’re right. I thought doing this outside would be ok but it would be wiser to have a mask as it’s caustic stuff. Regards
