Multi-purpose primer is rated 3.5 out of 5 by 4.
Rated 5 out of 5 by from Works good with Mapei Self Levelling Compound I used this to prime 1/4” wood underpayment prior to using the Mapei self levelling compound. It is a very liquid watery consistency. Just poured it directly on the floor which had been thoroughly cleaned first and used a paint roller to spread it around. Worked well and dries fairly quickly. No issues.

Rated 1 out of 5 by from Terrible adhesion! Mixed as per instructions, applied as per instructions. Did not dry clear and had less adhesion than if I had just wet down the area! I'm a contractor and have used cement primers more times than I can count. If the client doesn't insist on Mapei I'll NEVER use this again!

Rated 4 out of 5 by from Easy to apply, only used in the last month, a year First batch was milky and dried clear. Second batch was neon pink even though purchased within a month. Easy to apply time will tell. MAPEI technical support line was very helpful with specific questions about my project.

Rated 4 out of 5 by from No problems I wanted to pour self levelling concrete on my bathroom floor which was plywood. My tiler guy told me to use this stuff. It goes on very easily. I had no problems with the concrete after this. However it was my first time and not sure if this was necessary. Given its price, I was fine with applying it. It does leave a strong smell. Also, not sure if I read the instructions correctly but I got the impression you should pour the concrete on top of this no longer than 24 hours after applying it. Anyway make sure to read the instructions.
