Send a sample to Smart Seal. If no pool paint samples are available, follow the instructions under the How-To Procedures section and go to Step #1 Choosing Your Coatings.
Sometimes slight color variances occur between different batches. Smart Seal stamps a six digit "batch number" on each box so you can be sure your customer leaves with same batch number for any product. If not possible, have them "mix" the two batches in a large container prior to application.
Once the product has completely "set up", rain will not affect the coating. However, no standing water should be allowed to stand, i.e. main drain, this water should be pumped out or otherwise removed to prevent blistering and fading.
Prime It! is required on a bare surface only. On recoats of Dura Seal, a primer is not necessary. If spot priming is required, use Rough Prime. Prime It! should only be used on never before coated smooth plaster and concrete.
Improper surface preparation is the number one cause of blistering and other performance issues. Unacceptable application conditions such as heat or cold can also contribute, and always follow the proper curing schedule prior to filling the pool.
