Anybody out there know of the best way to prep a garage floor for a decent smooth paint finish?.....And or have some floor paint lying around?

[Lyford01]

Best thing to do is sweep it with a stiff brush to get rid of loose rubbish then Hoover the corners you should be able to find floor paint at any DIY superstore and lay a few coats down should leave you a smooth finish

Hope this helps

thanks. i believe though you need a stabiliser agent? As my house is new and the garage floor is very dusty. this true?

Sorry can't help with that it might be a case of asking the spotty do it all gimp or reading what it says on a couple of tins unless someone here can give you a definite answer

get PVA tub from the B&Q or the likes and leave a thin wash on your cleaned floor, once it dries, then paint with standard floor paint, otherwise it'll lift when you walk on it or park your tyres there.

I did one with bog standard white emulsion & a coat of granguard - essentially PU varnish. Not as pretty, but it lasted.

might also be worth a shot, there are loads of other brands & suppliers. It lasts plenty long enough on shop/school/hossie floors and is easy to strip (chemically).

the watered down pva like above first, the thin the paint down with white spirit on the first coat

you want the paint to soak down into the concrete and not just sit on the top where it can be scuffed off

I’d been looking to do the same in the hope that it would stop the damp rising up through the floor every time I rains. But a few things that I’d found that were putting me off were if I used a damp seal paint to seal out the damp on the inside. The only colour I could find was black, witch would then need over coating with something brighter or it would defeat the object of painting the walls to brighten it up in there.
Also the reviews of the garage floor paint I’ve found tend to suggest that it takes 48 hours to dry and about a week to fully go off, plus the fumes aren’t apparently too pleasant either. Which is a bit of a pain what with the garage being used as a workshop, storage and parking for the mini. So the only way I’d be able to paint the floor would be in sections and moving stuff round.
I don’t know if that’s the same as others experiences of using the stuff or have any suggestions for the damp problem?

Might sound weird, but I used an air gun to get rid of a lot of dust (even after a thorough sweep previously)

[spi_guy]

oh sure jesus you'd be sweeping forever, and there nwill still be dust! it'd break yer heart. inds. hoover cleared allot too, compressed air is a good idea.

Pressure washer with a wash broom or a patio cleaning head.

Which is exactly what a coat of PVA will prevent. Different primers exist for a reason, PVA is used for too much stuff that it simply isn't suited for. Loads of products now have it it their terms that if you use PVA to prime the guarantee is invalid. Wire brush it all over, then wash off the dust and leave to dry, then sweep it very clean, then seal it with concrete sealer, then paint it. International brand garage floor paint is good, although as above if you don't seal the concrete properly first it will lift where the tyres are sitting.
