Resealing pool deck pavers is vital to keep up the appearance of your pool and its surroundings. For best results, maintain a regular maintenance schedule. Always keep the pavers clean so as to avoid the degradation of the sealer. Re-seal the pavers at least once every 2 years. You can re-seal it sooner if you wish, depending on the quality of the sealer you have. It is also important to re-apply the sealer during days without rain in order to ensure that it dries properly. At least 3 rainless days are required for this. If you think it will rain, postpone the sealing of your pool deck pavers.
