3 part cement and 1 part sand...? Is this for S-type...?Type N or S are both fine for cultured (manufactured) stone, while Type S is better for natural thin veneer. You can find both in pre-mix bags relatively easily, and will be far more consistent than site mixed, or you can shoot for a 3:1 ratio or so..........
Thanks for your reply.I've just done this. I used Kerabond thinset, Mixed with keralactic additive instead of water. It seemed to be a 2:1 mix ratio.
You can use either S or N, and use the same ratio for either one. The most important part is to make sure you roughen the scratchcoat. Professionally, I see no reason to use expensive, messy, high strength thin-set when the cultured stone are typically less than 1500 psi in compressive strength and typically offer plenty of adhesion............3 part cement and 1 part sand...? Is this for S-type...?
I'm doing manufactured stone cladding. Which type will be good in terms of strength and economical?
