Will it work (and if so, what dilution) instead of buying
specialist
sealant
prior to painting?

in some cases, its commonly used for that, but not always suitable

The floor/walls in question are concrete (floor), brick
(3 walls) and pebbledash (house wall) in a garage.

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.


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.
