I have an area of internal plaster into which silicone solvent based injected dpc has leached.....It is not a large area, but I don't particularly want to have to start chopping off and replastering (and anyway, it's in the brickwork behind the plaster, so no doubt it would leach into new plaster as well).
I know that emulsion just isn't going to cover it, neither is oil based undercoat. Even SBR will not 'seal' it in.
In fact Stain Block won't work either [Just for interest, I have found something better and cheaper than Stain Block for most stains....Glidden Trade Endurance Brilliant White Pliolite Based Masonry Paint].
Previous to finding Glidden, I used Aluminium Paint on a stubborn bitumen stain, after trying nearly everything else, but I doubt if it will work on this silicone stain.
Has anyone got an idea of what I can use to cover it, short of low level wall panelling or hanging a sack over it?
Thanks JA.
