I had a new patio laid some ten years ago using good products but over the years and cleaning with a jet wash it could do with some maintenance such as re pointing is there any product which could withstand such treatment or if not which is the best type to use, many thanks I look forward to any advise regards Hugh

Hi Hugh, I don't think there are many surface products that can withstand pressure washing. All it needs is the slightest breach in the surface integrity and the high pressure water will start blowing it off. The only thing I could think of with any chance would be some kind of epoxy or some swimming pool resurfacing product.

Yeah,there are some that will withstand high pressure but you might pay a high price for them.

Commercial concrete repair,there are epoxy mixes,highway(and high traffic)mixes,etc.

What exactly is the damage on the surface,pock marks(say from rock salt being directly placed on it during the winter months?)or just surface cracks(perhaps from tree roots,ground settling?)The expansion joints opening?(like they will)
