    Hi

    We're buying a house that has some rather dubious (I'm trying to be polite here) decor decisions. In one room, 2 of the walls have been painted in blackboard paint and a teenager has vented their frustrations with life all over quite vividly in chalk! (I actually learned a few new words!)

    Obviously the chalk itself will wash off (before my 8 year old son increases his vocabulary), but what is the best way to cover the paint? Does blackboard paint need any special treatment before emulsion?

    Thanks

    I would think a coat of Zinsser 123 would be better first, it will block out the black better than applying several coats of emulsion.

    Did a blackboard for a a kid's play room a few years ago, I just use mdf sheet fixed to wall & several coats of blackboard paint, so much easy to return to a normal wall at a later date.

    Easiest way, wash walls, lightly go over with abrasive paper (120 grit), apply a coat of Zinsser 123 and then hang lining paper over the whole wall.

    If the wall is already papered simply stop it off and re-finish.

    Quick question to all our learned people on here, this Zinsser 123, that everyone harps on about, what exactly is it?, Cos until I started lurking on the forums I'd never heard of it, it sounds like a 'miracle' cure for a lot of ails.
    Cheers, Rich.

    Basically Zinsser products are a range of high adhesion primer/sealers, this includes to seal porous surfaces, block tough stains, they have superior adhesion to glossy hard to paint surfaces without sanding (glass & ceramic tiles), sealing odours, covering graffiti, Zinsser products cover a wide variety of substrates, wood, metals, varnish, formica, PVC, melamine, tiles, knots and sap bleed, masonry, concrete, vinyl, fire damage, mold & mildew. They are a pretty good all round piece of kit to have on the van.

    Thanks for all the help, it sounds like Zinsser is the way to go :) I'm sure I'll be using these forums quite a bit over the next year or so :)
