Will it work (and if so, what dilution) instead of buying specialist sealant prior to painting? The floor/walls in question are concrete (floor), brick (3 walls) and pebbledash (house wall) in a garage.

in some cases, its commonly used for that, but not always suitable
not nuff info
The concrete floor is bare, dusty concrete. The 3 brick walls are plain brick (and therefore very thirsty to anything applied to them) and the pebbledash wall is as described - used to be the side of the house. Can post pics if necessary.

specialist
the conrete paint will give full instructions on the tin. Coating the floor in pva first will not be part of it.
the others I just brush teh wall with water first so it doesnt suck everything dry immediately. This avoids the issues of pva. Its only if youre trying to hide something that a specialist sealer becomes relevant.

Not trying to hide anything, just want to paint it all so it's nice and sealed and better looking! I just thought, since I have plenty of PVA, that it might save buying a specialist sealer before I paint?
a
so what would you buy a specialist sealer for? If you want it to look good, paint is the normal solution.
I assume you realise a concrte floor paint is needed for concrete floors. These are hard wearing and stop dust.

Yes, and will use. Not sure whether to bother with the garage floor paint (supposedly more oil resistant as far as I can tell, but my car isn't oily anyway).
The walls are more of a concern. I know if I just paint the brick, it will soak up like a sponge. Was wondering if the PVA would help or if I should find something more specialised to seal it.
a
bother.
For the final time: paint it with a coat of water, wait 2 minutes, apply paint.
PVA is unsuitable for sealing for some paints (see recent thread on this). Dilute matt emulsion generally works well, but specialsed products are available too.
So just a few coats of normal emulsion will work or does it need masonry paint?
