POOL PAINT PREPARATION
QUESTIONS and ANSWERS
How can I be sure the pool surface is dry prior to painting my pool 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.
How do I repair my surface before painting my pool? 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.
What is the proper surface preparation for the pool? 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 pool 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 pool paint, the pool must be completely dry.

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.
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 pool epoxy primer first, such as, Pool Grip.
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 pool paint film for recoating.

Can I apply National products to a stainless steel or metal surfaced pool? Yes. Only if you sand properly, as steel is a tough surface for adhesion for pool paints, then apply Pool Guard EHB.
Can I apply National products to other metals? Yes. As long as the surface is prepared correctly and primed. If the metal is rusty, we recommend a Marine Bottom Primer like Bottom Shield 70 that can seal in the rust. If the metal is clean, we recommend applying Pool Grip as a base coat. Once the surface is primed you may apply your choice of National Pool Paint.
Can I apply National products to liner materials, such as vinyl? No. None of the available pool paint products will adhere to vinyl or similar materials.
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.
Can the pool be shocked with chlorine immediately after refilling? No. We don’t recommend chlorine shock at all to clean pools, but we do recommend chlorine-free shock.
Can I paint a Fiberglass diving board? Yes. We recommend our Pool Guard EHB with 1 can of Non Skid additive (1 pound per gallon).
