Hi, I am about to lay 40 sq mts of Marshalls Eclipse Paving, according to Marshalls ,when finished the 5mm gap should be pointed using a waterproof grout. Any ideas what I should use ?
You can point the Eclipse granite flags with a standard 4:1 Class II mortar. I'm not sure why they suggest a waterproof mortar, but if that's what you want to use, add a waterproofing additive or buy an external grade tile grout.
