Mapei Primer G 5kg is rated 4.8 out of 5 by 13.
Rated 4 out of 5 by from Needed for levelling floor Hard to say if a good product in terms of knowing if the floor will last, as two hours after first using/apply I did the levelling. With that said, applied well and looks a nice blue . Wish they had a half size as I will most likely not even use half and also it’s good to reduce waste, but ideal if you’re doing this type of job all the time so can appreciate that.

Rated 5 out of 5 by from Mapei primer. Mixed easily and went down well. I used two coats on a concrete floor and still have over half the tub left. Perhaps a half size would be useful.

Rated 5 out of 5 by from Great Primer Used this for priming the concrete floor of my garage before laying self levelling compound. It worked a treat. Goes on real easy with 1/1 mix and used a roller to lay it. Great product.

Rated 4 out of 5 by from Mapei Primer Used this for priming/sealing a screed floor in preparation for self levelling compound. Used it neat (without diluting) and it soaks up fast. Used about 80% of this on an area of 17 square metres. Looks like blue diluted PVA but had to use this for the Mapei self levelling. A bit expensive for what it is.

Rated 5 out of 5 by from Goes a long way I had just re-plaster boarded my Bathroom with MR plasterboard prior to tiling. Used a Mapei tanking kit for shower and bath area, but due to using a cement based tile adhesive this stuff was recommended for all other parts of walls. Wasn't sure about diluting it, but contacted Mapei support on the phone and was advised 50/50 dilution rate for MR ( Green) plasterboard. The walls got two good coats of this stuff ( approx. 16m2 and there's loads left. Maybe they could sell this in 2.5 litre tubs.
