Simple to apply — even in the rain

First, pre-wet the paving thoroughly and keep it wet. Don’t worry about water in the joints, so you can work in wet weather and even light rain.

Next, mix the epoxy pre-coated sand with the hardener to a uniform colour, as shown in the videos. Then spread it as a slurry with a squeegee and fine hose spray, so it self-compacts into the joints. It needs no further tooling.

Finally, let the excess water drain for a few minutes. Once the joints are full, rinse and clean off with a fine fan of water and a soft coconut brush.
