“I used this product on a 30 year old patio which had deeply marked coloured concrete paving slabs and the results are excellent. There are some ingrained marks that haven’t been removed but overall very pleased with the finished result.
I can support other reviewers who advised to wear old clothes, they do get splashed and permanently marked. Any plants that get splashed will die back completely. Be careful with wind direction when using, make sure you don’t get spray towards yourself.
A good product overall.”
“Have suffered with black spots on patio for a few years even after pressure washing didn’t budge it! This stuff is amazing, left on overnight, did it late in evening when everyone including dog inside for night. Very powerful smell so wear a mask! Rinsed off next day and amazing results!”
