Ronseal Decking Rescue Paint rescues old and tired decking, giving it a new lease of life so you don't have to replace it. It fills small cracks and locks down splinters, making your old, neglected decking look as good as new. It also provides long lasting weather protection and is resistant to foot traffic, so your decking will look better for longer. Give your grey, weathered decking a good scrub, let it completely dry and then apply a couple of coats of this paint. Leave four hours between each coat, then in 48 hours after application of the second coat you can start to use your decking again.
