Good stuff but don’t put anything near it that you want to keep, and cover yourself up well. It’s like a tar and sticks to anything, goes off quick too so you’ve no chance of getting the float out the tub if you put it down while rolling the floor. Covered about 4.5 sqm but it’s quite runny, so wants to run if the floor is not level. We’re not professional (although fairly experienced DIYers) and it worked well for us. We used it to create a dpm on a concrete floor with no damp barrier, to apply a screed in order to tile. The floor had also been flooded and was not in a great state, as numerous sets of tiles kept breaking down. We used this in conjunction with the primer and leveller in this range. Floor looks and feels good, yet to be tiled, so we’ll see how that goes. All in all a good product, worth forking out for.
