Approx. 3years ago I had my drive covered. It looked lovely however the sealant used caused a bubbling effect in a few odd spots.The whole area was re- skimmed. It was never sealed. Can you advise if there is a suitable product available which would be unlikely to cause problems.
I have come across this before, you have to be very, very careful applying a solvent based sealer on resin bound stone, you have to apply several mist coats, if you apply it too thickly you get the problem you had.
Because of this I now always recommend using a water based sealer, because there is no solvent there is no risk off it affecting the Stone.
