white stains on terracotta

| Asked by mandy thomson from angus: |
Hi there..I have stripped and sealed my terracotta floor with your sealer and I used about 10 coats.....now after a few weeks the floor still does not appeared sealed as most water is absorbed into tiles and some of the tiles are going white...do you have any suggestions as to how I can remedy this ? ...more coats of sealant perhaps ?? |

Hi Mandy,
White is not a good sign in this business, were the Tiles fully dried before you started sealing them, if not thena white bloom will apear due to the moisture in the Tiles reacting with the sealer that is trying to set, I have seen this rectify itself when it has been allowed to dry, so I would leave it for a week or so and then add more sealer at this stage its the best answer, otherwise it will mean stripping of all the new sealer and starting again.
