Floor paint

I bought a 5l tub of Febco[1] concrete sealer many years ago as it was a lot cheaper than paint and it worked well to reduce dust.

After trying a few different products for my factory floors, I eventually standardised on International garage floor paint, applied with a long handled 12" wide roller. It lasted at least as long as a professionally applied epoxy floor finish.

Yup roller or brush, you need to get it into the pores and nice and thick and glumpy. Smells a bit so plenty of ventilation unless you want a n out of body experience. Brian

I just brushed on some red concrete paint years ago amnd it did the job and kept the dust down

What happened to good old fashioned PVA?

I didn't think Dulux floor paint was much more expensive?

I've recently had excellent help and service from Watco and would heartily recommend them ...

Research waterglass (sodium silicate) and concrete surface treatment.

I had Watco epoxy paint on one of my factory floors. It was good, but I found it didn't last any longer than the International garage floor paint I mentioned elsewhere in this thread and the latter was quite a lot cheaper.

I did and got this article:

which found little or no improvement using Sodium Silicate in most instances.

Did not wish to start an in depth discussion on hardening concrete which was not the question,the poster said his concrete was dusty and should he paint it(which by the way does not harden the concrete) My suggestion was purely a method of sealing to stop dust which could be much cheaper depending on how he sources the waterglass.

OK - in the past PVA has been the solution.

I did mention it earlier and surprised no one else have mentioned it.

It's an excellent solution if dust is an issue.
