Before applying the refinishing solution, most pool surfaces will need a primer epoxy. Follow the directions on the package and apply the primer using gloves and masks to block harmful fumes. The primer should be applied to the entire pool surface. Allow it to dry completely before you continue. Depending on the size of your pool, this process will take between two and four hours.
It’s common to see tile used as a border at a pool’s waterline, but ceramic, porcelain, stone, or glass tile can be installed over the entire pool surface, in every imaginable design. Applied over the plaster, tile is installed in much the same way as it is in a bathroom: mats of small tile or larger individual tiles are glued to the plaster substrate with thinset.
Pebble-plaster concrete aggregates, like Pebble Tec or Pebble Sheen may be the most expensive option in this category but they have a distinctive look and a river rock-like texture beneathfoot. Pebble-mixtures are also among the most stain and chemical-resistant of all plaster types.
