We have just spent the afternoon weeding the patio and blasting it and all the furniture withe the Karcher.
I have said to my husband that we now need to brush some sort of sand into the cracks but we don't know what sort of sand. We have a bag of sharp sand. Will that do, or does it have to be a special kind?
Sorry Tilly, if your patio is slabbed, then mix a bit of cement in with your sharp sand and make a dry mix, and then brush it into the cracks, natural moisture will then set it.
