Priming fresh plaster and sigma cutters.

[Dave]

Hi David what is meant by skinning?

its when the primers applied to neat / thick and it's doesn't penetrate the substrate and just sits on the surface and creates a skin which can peel off .

by diluting to say 4:1 , this allows the primer to soak in and you apply a couple coats to create that barrier to help prevent ettrignite formation when using cement based adhesives to gypsum based backgrounds. .

What would you guys on here recommend for the adhesive.
I've always used mapei in the past and liked the stuff.
Would mapegrip d2 be a good choice or would people on here use a powered mix and mix it themselves.

Go for mapei p9 slow set flexible and mix it yourself. Tub gear takes ages to dry
