Ronseal Wet Rot Wood Hardener.
DO NOT USE THIS PRODUCT! There are no warnings on the packaging about the damage that this product can do! Get one drip onto window frames, composite front doors of patio flagstones then that’s it, the product does not come off, even with a pressure washer and Ronseal do not care! This product is going to cost me around £4000 to rectify the damage it had caused! Use something else made by a company that gives a damn!
