We had a pebblestone pool deck installed in 2005. We love it! It looks still great and water drains immediately. However, it does take a coat of solvent based sealer every other year. We just found out that the company we bought it from (Seamco/Dyco) no longer can ship it to Pennsylvania. Does anyone know of another sealer we can use? Hopefully one we can buy in PA. Thanks for any suggestions.
