Sealing Concrete Garage Floor

I'm looking to seal the concrete floor in our garage to stop the dustyness that tends to form on the bare concrete.

I've seen the stuff used by cleaners which goes on then sets into an almost varnish-like shiney layer, but being unable to find it from normal DIY outlets i picked up some "pave seal" from B&Q, which promised to seal and protect concrete floors from dusting and also protect it from oil and suchlike. Perfect i thaught.

However i've just been out and spend a while testing this stuff out, and i'm not particularly impressed. Its not very viscous, and TBH seems almost like just pouring white spirit all over the floor. It claims 5-8m^2 per litre on the tin and i've managed to use 5 litres of the stuff putting two coats onto half the garage floor, which is about 3m x 3m.

Problem is, it doesnt actally seem to have done anything. Once dry the bare concrete looks no different to the untreated stuff.

So assuming this stuff is just crap, can anyone recommend a better treatment, or should i try and find a janitorial supply shop and buy the cleaning stuff i was thinking of getting first time round?

My father-in-law is a painter and decorator and I asked him what is the best sort of paint for garage floors. Like you, ours is dusty as hell. He said boiled oil (think it was linseed oil). Told a story from years ago when he worked in a factory where boiled oil was spilt over a concrete floor by mistake. It set like a resin over the floor, sealing the concrete perfectly.

If the floor had been 35 newton concrete and polished with a power float then no dust and no paint necesary.

Is the floor still dusty after applying this stuff? Give it all a hoover and then sweep the treated and untreated sections to see how loose the particles are on the surface.

Wickes sell a concrete floor dustproofer but you can get away with watering down PVA and brushing that on. This will make the floor less porous and you can then give it a coat or two of garage floor paint.

Sorry to resurrect this old thread, but I'm having this same problem.

I've also heard that mixing some PVA and water is a good sealing solution. However, I'd like to know if or how the surface might look after applying this? Would it go shiny like some of the pave seal type stuff? If so, I might try the Wickes stuff, as I'd prefer it to still look like normal matt concrete.
