I finished the test of the cleaning of slate tiles. When dry we applied 2 x coats of a oil an water repellent. After cleaning the tiles with correct products the original colours really came out.

Two big days preparing large 900 x 900 slate tiles in driveway, entrance, surrounding pool and side of house. After scrubbing with a heavy duty detergent it appears that the tiles were not cleaned properly previously (3 years) and a grout haze has remained.
We ended up scrubbing with 3 detergents and neutralizing with S4S stone cleaner. a lot of work but the results are great.
Tomorrow we will seal the stone to protect against oil and water. Pictures and more later.
