    Default Painting precast slabs/wall

    Gents , our precast wall/slabs paint are coming off & needs to be cleaned/old paint flakes to be scrubbed off & then repainted.What is the best paint for doing this? Will micatex do?
    someone suggested to add little bit of plaster key to the paint so it sticks to the slabs?
    Any ideas advice much appreciated

    Well they are raw concrete which would be the reason for the original paint coming off in the first place. I would imagine plaster primer or bonding liquid at a minimum would be required before painting.

    Plaster Primer is the correct answer.

    But I painted mine, raw, with Roof Tile paint (Deep Green) & they have never peeled.
    Because the precast is now covered with creepers or plants I haven't been able to repaint for years.
    Still looks good.

    Thanx Manny...would you suggest to add/mix little bit of Plaster Primer in the paint? Think the ratio was 2L primer to 20L paint...

    Forget about any primer. You need to put one coat of bonding liquid, allow to dry and them paint.

    It's like adding 2SO to your diesel.
    It's stupid, wasteful, doesn't work & is not advised.

    Me too. And we had turf soil with rising damp, even that didn't get the stuff to fall off.

    Colour matching is a woman's job.

    Match precast wall, palisades and house roof and gutters. House walls must contrast.

    Bonding liquid is a primer in a sense.
