Have decided to use the Mapei Ultraplan renovation screed sold at Screwfix but cannot find any information on whether the cement floor screed has to be primed first. If so would BAL SBR primer be suitable as I have some left over after tiling.

One last silly question (hopefully). The levelling compound must be spread a minimum thickness of 2mm but how do you know the thickness you have put down. I thought of fixing something 2mm thick onto the highest part of the floor and ensure that this just gets covered with the mix.

2mm spacer on your high point, come off that with a 400 level n stick however many 2 mil spacers together to give you your depths

Casper another similar method is to insert screws at say 600mm intervals into the floor coming of the your desired finished substrate height using a level and simply fill the leveller up to the top of the screw heads which will all be level with each other, just avoid pipes!

if you were thinking of laying vinyl I'd personally go for a 2 part like Ardex NA. You get a much smoother finish than a water based fibre re enforced one
