I'm about to tile a 1950's kitchen concrete floor using Mapei Super flexible adhesive. I'm laying ProWarm boards first using the same adhesive and then the tiles.
I'm got some Bostik Concrete Sealer but I can't establish if it's suitable as a primer or not. Can anyone confirm?
I want to prime tonight so I can make a start with the boards tomorrow, so can anyone recommend a toolstation/screwfix product that is suitable if the Bostik product is not?
I was thinking the following Mapei Primer but not clear which surfaces it's for and which products it can be used with: https://www.screwfix.com/p/mapei-primer-g-5kg/5309p
Reading the back of the Mapei adhesive, there is no mention of a requirement to seal concrete floors other than it saying "very porous surfaces may be primed with Mapei Plaster Primer....".
Not sure if I would describe my concrete floor as very porous, nor would I describe it as plaster so I'm at a bit of a loss.
Thanks for any input.
