Frequently Asked Questions

PREPARATION

1. How can I be sure the pool surface is dry prior to painting with a solvent base paint?

We recommend that you tape clear plastic on the vertical wall and if no condensation shows, then the pool is dry and ready for overcoating.

2. How do I repair my surface before painting?

If it’s a hairline crack, Pool Guard EHB will fill it in. If it’s a big­ger job then use a caulking agent Polyurethane Sealant & if it’s a larger repair, a concrete repair is needed.

3. 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.

APPLICATION

6. Can I apply epoxy paint over chlorinated rubber paint or chlorinated rubber paint over epoxy paint?

Different technologies are not compatible, so we recommend chlorinated rubber over chlorinated rubber, epoxy over epoxy. However, if you put our epoxy primer on first, then the different paint can be used with no issues.

7. Can I apply any pool paint over another type of pool paint?

Aqua Kote can be applied over anything, Pool Shield CRX over any chlorinated rubber paint, Pool Guard EHB over any epoxy paint. If you want to switch, you must use an epoxy primer first.

8. How long can I recoat the pool with no sanding requirements for your Pool Guard EHB?

You can recoat a pool up to 72 hours without sanding. If win­dow is missed then sanding and/or a Muriatic acid wash must be done to “open” up the paint film for recoating.

9. Can you apply Pool Guard EHB over Pool Shield or Aqua Kote?

You cannot apply Pool Guard EHB over Pool Shield or Aqua Kote unless you put a primer on before.

10. Can I apply epoxy paint over chlorinated rubber paint or chlorinated rubber paint over epoxy paint?

Aqua Kote can be applied over anything, Pool Shield CRX over any chlorinated rubber paint, Pool Guard EHB over any epoxy paint. If you want to switch, you must use an epoxy primer first.

Yes. Only if you sand properly, as steel is a tough surface for ad­hesion for pool paints, then apply Pool Guard EHB.

13. How do I determine what type of paint is currently on my pool or spa?

Take a paint chip and dip it in a strong solvent (Xylene), and if it dissolves, it’s a chlorinated rubber paint, then use Pool Shield CRX to overcoat it. If the paint chip doesn’t melt, then it’s an epoxy paint, then use Pool Guard EHB.
