Epoxy pool paint is the longest lasting at up to 8 years and provides a hard, non-porous tile finish. It is easy to clean and stands up to chemicals and automatic cleaners.

Step by Step

Top

Step 1

Inyo Pools carries Ramuc EP Hi-Build Epoxy pool paint so this guide will be based on the instructions for that brand.

Step 2

If your pool is already painted, the existing paint type should be determined for compatibility before applying any new paint. This can be determined by sending a sample to Ramuc (or other paint manufcturer) if the paint type is unknown. There are also a few tests you can try. Take a 1 inch paint chip, immerse it in denatured alcohol. If the chip dissolves, it is a water-based acrylic. If it doesn't dissolve, immerse a new chip in 75% mineral spirits and 25% Xylol, wait 30 seconds and rub the chip between your thumb and forefinger. If it dissolves, the paint is a synthetic rubber-base coating. If not, try immersing one last chip in 100% Xylol. If it dissolves, the paint type is chlorinated rubber; if it does not, it is an epoxy. You can see our paint compatibility chart at http://www.inyopools.com/images/pool_paint_compatibility.gif.

Step 3

If you do not already know how many gallons of pool paint you will need, use the calculator at http://www.ramucpoolpaint.com/calculator.asp.

Step 4

You will need the following cleaning supplies: Ramuc Clean and Prep Solution or Tri-sodium phosphate (TSP) and muriatic or sulfamic acid solution; high pressure power washer with minimum 3000 p.s.i. and turbo tip attachment. For surfaces previously painted with epoxy, you will also need #80 grit sandpaper, a power sander, sanding block and a wire brush.

Step 5

For epoxy paint, a condensation test will also be required, using several one-foot square pieces of transparent plastic and duct tape.

Step 6

You will need the following painting supplies: Roller for solvent-based coatings with maximum 3/8" nap; paint brush; 5 gallon bucket to intermix paint; mechanical mixer (paddle attachment on a power drill can be used); Ramuc Thinner or xylene for thinning paint and clean-up.

Step 7

For joint and crack filler, you will need hydraulic cement or Durathane® polyurethane sealant or any other submersible polyurethane sealant (do not use silicone-based products). Durathane must be topcoated before submersing with chemically treated water.

Step 8

If your pool surface is plaster, concrete or gunite, it should be tested for integrity and repaired before you begin. Follow the instructions provided by the manufacturer of the hydraulic cement patch or crack joint filling.

Step 9

If the pool surface is previously painted epoxy or bare fiberglass, it will need to be abraded to a 80# grit profile. Pressure wash using the turbo tip, taking special care on an epoxy surface to remove all chalky residue. Then scrub all pool surfaces with the TSP solution to remove all dirt, oils, chalk and loose paint.

Step 10

Wash (etch) the surface with a 15 - 20% solution of muriatic or sulfamic acid (follow manufacturer's instructions on label). Following the acid treatment, neutralize acid-treated surfaces with TSP and water. After this etching, the a bare concrete or plaster surface should feel similar to medium grade sandpaper.

Step 11

After the washing and etching is complete, allow the surface to dry for at least five dry days. You will then conduct a condensation test by using duct tape to apply the 1 foot square pieces of transparent plastic to the pool surface. Place them on the deep end wall and floor, and on a few other areas. Wait three hours and then check if condensation has formed underneath; if it has, you should remove the plastic, wait 24 hours and then test it again. Repeat until there is no condensation.

Step 12

Ramuc EP Hi-Build Epoxy pool paint requires no primer. Primer should not be used. Using a mechanical mixer, mix Part A for about 5 minutes. Then mix Part B for about 5 minutes. Combine both parts into your 5 gallon bucket and mechanically mix for about 15 minutes. If you are using more than one 2 gallon kit, intermix (box) the kits for uniform color.

Step 13

Once mixing is complete, allow the paint to set for 20 - 45 minutes prior to use at 70 degrees F and 50% relative humidity; at 65 degrees F the set time is 45 minutes. Lower temperatures and higher humidity will affect the final cure of the coating. The pot life (or use life) of Ramuc EP Hi-Build Epoxy pool paint is three hours.

Step 14

To apply, use a phenolic core roller for solvent-based coatings with maximum 3/8" nap (mohair or lambskin). Apply paint at the recommended coverage rate during ideal air and surface temperatures of 50 - 90 degrees F. Never paint when rain is expected.

Step 15

When done, wait 5 - 7 accumulative dry days before filling an outdoor pool, meaning you add an additional day of drying time for each day of rain. You would wait 10 - 14 days for an indoor pool with proper ventilation. To recoat, apply paint within 16 - 72 hours. If after 72 hours, you must sand the first coat before applying another coat.

Carol - It may well have been caused by the night moisture. You may just have to let it dry another day or two. I'd discuss this with your paint dealer if it's still not glossy.


Carol  Posted: 06/14/2017 0:01 AM 

We recently painted our fiberglass pool. We sanded and cleaned. Painted on a Saturday and later in the day noticed spots missed on floor. So we mixed up paint and repainted the floor. This was early evening. The next afternoon we noticed that the floor finish was dull not glossy like side. Not sure why. Could it have been the dew?

suterflash - If you add sand, I'd go easy with it. You don't want to create too abrasive a surface. It's bad for knees and elbows.


Suterflash  Posted: 05/15/2017 12:54 PM 

Do you suggest or have heard of putting a little sand in the area of the steps and shallow end of the pool so the Epoxy painted areas are not so slippery?

Anonymous (Epoxy paint) - The pools surface that you are painting has to be solid. Any portions that might flake or chip off must be removed before you add a new coat. If the cracks in the epoxy are large, I would fill them with the crack filler suggested in step 7.

Anonymous (peeling paint) - Epoxy paint can only be applied over unpainted surfaces or surfaces previously painted with epoxy. See our guide on "How to Select the Proper Paint for Your Pool" to determine what paint you had. If it was painted with epoxy and is peeling. you have to strip all the peeling paint away and get down to a solid base before repainting the pool with epoxy.

Going to put new epoxy coat on concrete pool. Previous coat has some cracks in the epoxy and a couple of chips where epoxy is too thick. What should be done with these areas before putting on new coat ?

We have peeling paint - can apoxy be applied
Over the paint to stop the peeling ? After we get the paint chips off / Out of the pool ?
We want a quickest a easy fix
We don't want to swim with the peeling paint either
The pool is over 30 yrs old - concrete

Ken - If your current paint surface is sound you just have to clean it and rough it up. If the surface is flaky, you will have to power wash any that is loose and get down to a solid base.


Ken  Posted: 04/10/2017 21:14 PM 

My pool is painted with epoxy, I want to repaint, does the existing epoxy need to be sanded off or just roughed up ?

worn gunite - Unfortunately , we do not sell that product. But whatever you use, the key is to make sure the patches and all the gunite around it are solid. I'd suggest calling our paint supplier, Ramuc Paint at 973-776-8271, for more information.


Anonymous  Posted: 11/17/2016 18:39 PM 

I have several areas around the pool where the gunite has worn away, up to an 1/8 of an inch. What can I use to smooth out these areas?

ivette - Ramuc paint is lead free. Their labels do show that paint contains cancer causing chemicals, but their sale is approved in states like California that strongly regulate these chemicals.


inyopools  Posted: 11/07/2016 14:41 PM  Inyo Product Specialist

Scott - The Ramux EP Hi-Build Epoxy paint that we sell has a satin finish that is less slippery than the high gloss finish of many epoxy paints.


ivette  Posted: 11/03/2016 17:12 PM 

Is the paint lead free, are there any cancer causing chemicals in it?


Scott  Posted: 11/02/2016 20:04 PM 

Will the final product leave the pool bottom slippery ? I have epoxy on my garage floors and when wet they are extremely slick and dangerous. Thx

Adam - According to the Ramuc Paint Manufactures, you cannot use epoxy paint on a pool surface that was previously painted with chlorinated rubber. See their "paint compatibility chart". Here is a link to their recommended paint with painting instructions - "How to Paint a Pool with Acrylic Paint".


Adam  Posted: 06/02/2016 18:58 PM 

Will these steps work if the pool was previously painted with chlorinated rubber.

It is a swimquip concrete bottom with fiberglass sides.

Can I and etch, clean and paint with epoxy?

sneuf - An epoxy paint is recommended for steel-walled pools. Steel may require special preparation like etching and rust proof priming. I would recommend calling our Ramuc Paint manufacturer at 973-776-8271 for specific instructions on your pool.


sneuf  Posted: 04/13/2016 14:27 PM 

Hello,
I have an in-ground steel walled pool. Is Epoxy paint the best solution for this type of pool? What do I need to do to the steel to prepare it for painting?
Thank you.

bdcraig - I have not heard of this particular problem. I would suggest calling Ramuc Paint at 973-776-8271. They may have more information on addressing this border issue.


bdcraig  Posted: 03/06/2016 16:20 PM 

My gunite pool has never been painted. I have heard that the epoxy paint sometimes fails where the top of the gunite meets the tile which is approximately 4" below the waterline. Someone said I should first undercut this border before painting so there is no lip for the water to get under. What do you think?


Inyopools  Posted: 10/24/2015 13:52 PM  Inyo Product Specialist

Jim - You are right. If the plaster base you are painting is loose (or wet), the paint will not adhere to the base. I know of no product that will solidify the plaster base, but maybe the paint manufacturer might. Ramuc telephone number is (800) 745-6756.


jim  Posted: 10/21/2015 23:23 PM 

About 9 months ago I used Rumic Epoxy to paint my gunite pool rather than re-plaster. I followed the directions carefully such as you have here including using TPS and acid. Shortly after filling, some portions of the paint flaked off. I think in these spots the plaster was probably pretty loose when I painted it. My plan is to redo these spots in a few months. My question - is there something I can do to enhance the integrity of the plaster before re-paining these spots, such as applying a varnish or something to penetrate the old plaster and solidify it more? My concern is if I just re-paint these spots, the paint will just peal off again!

primer paint - As stated in Step 12, you should not use a primer before painting a pool with epoxy paint. It is, however, very important that you follow the surface preparation instructions prior to painting your pool with epoxy.

Can I use it primer before painting a pool with apoxy paint


Anonymous  Posted: 04/23/2014 16:53 PM 

Can you elaborate on your recommendation to use Durathane® polyurethane sealant? I will be redoing the vertical joints between the fiberglass panels of my hybrid pool and people are recommending using the BOSS 802 silicone caulking for that. Are silicone-based product incompatible with your paint?
Thanks!

Painting acrylic steps - I would use the premium acrylic paint on these steps.


Anonymous  Posted: 04/18/2014 18:32 PM 

Can this epoxy be used on thermoplastic or acrylic pool steps in a vinyl liner pool?


Inyopools  Posted: 04/01/2014 10:10 AM  Inyo Product Specialist

epoxy paint - Yes, you can use epoxy paint to cover the tiles on the upper edge of you pool. For best adhesion you should rough up the smooth surface with 80 grit sandpaper. Then clean it off with a TSP solution. Follow the rest of our instructions in this guide.

I will like to know if epoxy paint can be use on tiles that are inside around a outdoor swimming pool and the water will touch some of them...thank u !!!!
