    Hi all , I’m doing up an 1910  farm house at the moment, which had previously had its external render completely remove & then the southern facing wall was pointed in PUre CEMENT which had major damp issues ,  I now have removed all concrete pointing ! My question is this , there is a lot of discussion at the moment regarding NHL3.5  and there suitability’s for pointing as it will keep strengthening! (In 10years it might be like cement) 

    Should I use hotlime instead ? 

    I know the house will have to be completely lime plaster but the time of the year is against me ! 

    The wall is bare inside & out and is very wet 🙈thanks in advance , total confused lime converter

    I think hot lime is the best but often not essential. id suggest calling one of the big lime suppliers and asking them.

    NHL 3.5 but it's the wrong time of year for lime plastering. Your time enough to April. Be no harm to let the wall dry out for a while before plastering

    Thanks, I think I’ll do a bit more research but I am going towards the hotlime way 👍
