“I wasn't sure this product would work on our old paving slabs but was I wrong. This stuff is amazing and does what it says. I would highly recommend that you buy a pressure sprayer to apply the product, they cost as little as £7 but give you the even coverage and makes the product go further. Wear a mask, protective clothing and shoe covers otherwise, you'll have bleach stains. We covered the area at night and left until the morning before washing away and seeing what looks like new tiles. Very Impressed.”
