What is the proper surface preparation for the pool? Surface must always be clean, dry and properly prepared prior to painting. Failure to do so will lead to eventually blistering and/or peeling. Previously painted surfaces should be Power Washed to remove loose paint or excessive chalking. Scrub the entire pool with a TSP (tri-sodium phosphate) solution to remove all dirt, oils, loose or peeling paint, and chalk. All surfaces should then be acid etched with a 15-20% solution of Muriatic Acid to achieve a medium grade sandpaper finish on bare or plaster and to remove mineral deposits on previously painted chlorinated rubber surfaces. Neutralize/rinse with TSP. Before applying the paint, the pool must be completely dry.

How can I be sure the pool surface is dry prior to painting with a solvent
base pool paint? We recommend that you tape clear plastic on the vertical wall and if no condensation shows, then the pool is dry & ready for overcoating.

What pool paint can I put on an existing latex based pool paint? As long as you prime over the latex paint first, you can apply whichever type pool paint you prefer. Applying directly to latex paint could cause adhesion problems later. We recommend priming the surface with Pool Grip Waterbased Epoxy Primer.

Apply Paint Over Polyethylene, Polypropylene, ABS, and PET/PBT Blends

You can apply paint over Polyethylene, Polypropylene, ABS, and PET/PBT Blends with proper surface preparation and primer.

1. First wipes down the surface with a 50/50 Isopropyl Alcohol such as Denatured Alcohol to remove any contaminants prior to sanding.

2. Sand the surface with 60-80 grit sandpaper.

3. Wipe down the surface again with 50/50 Isopropyl Alcohol ( Denatured Alcohol ) to remove all sanding residue.

4. Apply 3M Tape Primer over a small section.M23929

5. Apply a small test section of the desired Topcoat paint. Since there are so many type of paints, it is recommended to perform an adhesion test on the small area painted. Once the paint has dried perform a hatch test. Use a razor blade to cut into the paint and the primer and draw a 2-3 inch line. You should follow this at least 3 more parallel lines about 1cm apart. Then cut 4 more perpendicular line again about 1cm apart. It should like a large tic-tac-toe game. Finally, apply duct tape firmly and then pull the tape off quickly. If you have any paint or primer on the tape the adhesion is poor. If there is no paint or primer on the tape then it is safe to apply the primer and paint over the entire surface.

This application and test can be used for topside paints and bottom paints.
