Several years ago, together with a builder pal, and a farmer with a digger, I changed a steep lawned area into 3 large tiered patio areas.
I made the big mistake of ‘ dot and dab’ instead of laying the stone flags onto a solid base. The patio stonework became unstable, mortar dropped out, water got under everywhere and I’m now lifting and re laying on a solid base. So far we’ve used 6 tonne bags of grit sand, 36 sacks of cement, and filled 3 mini skips with the old dot and dab mortar and jointing.
Once re laid, rather than the time honoured way of grouting between the Indian stone flags, I’m contemplating using a 2 part epoxy slurry. Far more expensive, but much quicker so a saving on my pals labour rates, and it will withstand the annual pressure washing far better. In theory.
Has anyone any experience of using this stuff....the YouTube videos of Nexus Projoint V75 are pretty impressive.
