Recomendations for sealing concrete floor

I'm having a small shed erected in two weeks and I want to seal the slab before I begin filling the shed up. Most of the concrete sealers and paint I've looked at require between 4-8 weeks for the new concrete to cure and also require acid etching of the concrete.

Can anyone recommend a floor sealer or paint (preferably one that doesn't require prior acid etching) that can be applied to new, uncured concrete? Also, some of the better looking coatings are only available in 20 litre quantities. I'll only need one or two 4 litre cans.
