Mastic asphalt sub-floor problem?

Question

Any UK Floorlayers or Carpetfitters able to offer advice on applying a`Wicks` Laytex self levelling compound over a mastic asphalt sub-floor!

The instructions state -`subfloor must be clean dry free froom any loose material and contaminatants such as grease or thick adheasive residue and then to P.V.A.

Now, here is my delima, the sub floor had been completly painted right up to skirtings with a vinyl silk emulsion, using pan scourers I have in a fashion removed some and its difficult and I am worried I may make whats left unstable for the compound to grip. Consequently, am I fine to leave the paint {paint is in very good condition} on and use the self levelling compound over the top or best to continue to remove paint?

Answers appreciated thanks

Answer 1

Would say that if the paint surface is as hard to remove as you say, and that you have got as much loose debris up as possible thatn the compound should lay fine. I asked my brother about this (he's a builder) and he said they lay compound on all sorts, as long as the ground is solid you should be fine.

Answer 2

no count if it particularly is no longer an excellent room i might say scrape it off, if its the black shape mastic, I used a hair dryer to form of soften it first,use a putty knife warmth them the two at the same time and it comes off especially ordinary....If its an excellent room then i might say use a sander and in simple terms make it as gentle and point as available, in the adventure that your putting tile over it that's greater forgiving than in case you have been to disguise it with linoleum.

Answer 3

dead simple...coat your floor with a PVA coat ( primer, available at all DIY stores) then proseed to latex over the top....job done.

Answer 4

as long as its latex you will have no problem
