Hi folks,
Planning on getting a patio laid some time soon - on a bed of 50mm mortar made with sharp sand and mixing SBR in for strength & stickiness.
Anybody know if I need to (or should bother) adding a chloride-free frost proofer? Or will the SBR be enough by itself?
I wonder if the SBR is enough by itself since it will make the mix set quickly, I don't want to add a frost proofer too and have it set too quickly to work...
