    Hi all,

    I am priming a floor very soon. Im using Mapei Primer G.

    The instructions say to mix primer 1:3 with water when applying to already poured SLC. This is what I'm pouring onto.

    I just wanted to be absolutely sure that what I do is 1 part of primer to 3 parts of water? Or, to put it another way I would use 1L of primer and 3L of water. (A an example)

    Is that right? IE that the primer is always the first component and water always the second?

    Doesn't matter what order you mix primer with water.

    On porus surfaces first do a coat what of ever the ratio to water is (some primers are different) If it soaks very very quickly repeat that and then put a neat coat on top.

    Always do a small test first as some concrete needs more wate adder so it soaks in. If the primer can be peeled off or rubber off with your fingers when it's dry it needs a more water. Or if it takes a long time to soak in then less water
