My floor is driving me mad!

About 2 months ago I added a workshop to the back of my garage. Problem is the new concrete floor is continously dusting. Every time I sweep it it dusts up. This week I've applied 2 bottles of sealer from Wickes, I applied it exactly as advised in 3 coats but it hasn't make any difference. I've then applied 2 additional final coats and still rubbish.

Thing is I want to improve the garage next year my removing render and painting the walls/replacing roof etc and hope to put down a decent interlocking tile or paint (probably epoxy).

In the meantime I want to stop this dusting. Any ideas on best solution?

Thanks in advance!
David

Thanks guys for the rapid response!

It's been down for around 3 months and to be honest that is more than enough time for it to have cured. On site you can load up Holorib concrete floors after 2 weeks!

I think the problem is these ready mix companies often add more water than is actually needed to keep it workable. The result being when you vibrate & then float the surface the cement/ballast settles leaving a watery weak layer at the top, this obviously remains weaker under traffic as the bulkier aggregate is deeper down. In hindsight I should have left it 50mm lower an then finished with a structural fibre screed!

I must admit I think I'll go down the PVA route and then paint at a later date.

I went the PVA route and no more dust! Down side is I used standard PVA as I wasn't sure I'd be able to paint the waterproof PVA, which means if it gets wet it become 'live' again.

Can't wait to paint it!!!! What's the best paint?
