Hello all. I was wondering if I could get any suggestions. I have searched through the forum to find out about tennis courts before I went to a quote today. Thanks for all the advice I got there a bit early which was great as I was able to do a couple of test areas before my contact arrived. The areas I treated were black (on a green surface) before I did it. After 20 min I was getting great results. When my contact arrived we got talking. He showed me an area that looked great where on the edges there had been some over spray from some weedkiller that was used on the edges of the court. He then proceeded to tell me that have been pressure washing up until this point, which they want to move away from as the surface is quite old.

The court has an asphalt base, but apparently has a rubber coating over this and then painted green. He has been advised not to use bleach on this surface. I said I would get back to him. The couple of test areas I did however, he was impressed by. Has anyone got any suggestions on getting him over the line, or is there a danger that I could cause any damage.

Any feedback would be much appreciated

Kind Regards

Garon
