ecoFinish is perfect for discolored, old, and chalky fiberglass pool surfaces. It can also be used on fiberglass pools that have previously gel coated. The prep is the critical part. Sandblasting or Sanding are the key for gel coat pool prep.
The truth about ecoFinish is that it is an amazing product. There is a key to it being installed correctly – it needs to be done by an installer that is approved by ecoFinish and who knows what they are doing. Prep of the pool surface is critical, as well as following the ecoFinish protocol to achieve a chemical bond AND a mechanical bond for the best finish possible.
