Results apply to the tested system. Performance on your floor depends on the substrate, preparation, application and maintenance – test on a sample first.
How it goes down
Fast dry times mean more than one coat in a single day, which is why a floor can be resurfaced in a break between shows.
Always test on a sample first — before you go any further
Every project is different: the surface, the substrate, the prep, the traffic, the conditions. No approach applies across the board. Paint a test area of your actual floor, confirm you are happy with the coverage, colour and durability, and document what you did — product, coats, dilution, date. Only then do the whole floor.
Prepare
Clean, dry and sound. Remove loose or flaking paint, vacuum off dust, and lightly abrade glossy or previously coated areas so it can grip.
Seal porous areas
It is the primer, so no separate undercoat is needed. On very absorbent bare MDF, chipboard or raw ply, a thinned first coat evens out the porosity. Concrete needs proper prep first.
First coat
Lay on a thin, even coat by brush, roller or spray. Thin coats level better and dry harder than one heavy coat.
Recoat the same day
Touch dry in 30 to 45 minutes, recoat in 1 to 2 hours. Two coats suits most floors and both can go on in a day. If your floor is porous, a third coat may be needed — always test your own floor first, as every one varies.
Let it cure
Let the finish dry and cure before wagons, equipment and traffic return to the floor. Allow extra time where you can.
Touch up as needed
Later on, scuff the worn area, clean it and recoat. No strip-back, no full repaint unless you want one.
