hi , moved into house ripped off some 1970's wood effect panels off kitchen walls to find just painted brick , plasterer has requested me to apply some sort of primer before he can dot & dab board on top , what do i use to prep the walls .many thanks
Shouldn't really need to prep walls for dot n dab really. If it was bare unpainted brick then the only thing I do is to dampen the bricks down first before applying the adhesive.
there is a chance that the walls may have been glossed. if so, use a strong pva mix, only dilute to say 50/50. apply the mud whilst the pva is still tacky.
thanks for replys , i was a little suprised with what he wants , i dont mind helping anyone so longs as decent job is done and price is right , had a few quotes this one i choose on recomendation and price but like you say his job, cheers ,dave
As a general rule of thumb, PVA is the stuff to use, However, there are some surfaces that are too smooth and not porous enough to provide a key for the finishing coat so the skim just slides about everywhere and makes a horrible mess. In addition, it doesn't bond too well when dry and is quite likely to come off in nice big sheets.
That's where the Bond It comes in. Spread it on. Leave overnight. Bingo. Lovely rough surface to plaster.
