Solvent-Free Epoxy for Industrial Purposes

What Makes Water Gard 300™ a Superior Epoxy Coating for Your Application?

Water Gard 300™ is not a simple epoxy paint but rather, an epoxy adduct. In general terms, epoxy adducts have some of the Part A resin added to the Part B curing agent during manufacture. The result is improvement in most of the coating's physical properties. This includes reduced yellowing, better curing, and a host of other property improvements. A better epoxy for better results!

A proven performer with lots of history and industrial case studies to back up its performance.

A solvent-free, non-hazmat epoxy adduct. Used for tanks, pits, secondary containment, pipelines, etc. Coverage is approx. 130 sq. ft. per gallon.

Standard Color: white and light blue.

Uses a non-hazmat cycloaliphatic curing agent. Popular marine barrier coat on fiberglass boat hulls. Can be applied underwater, with some site-specific exceptions—See user notes and charge pages. Because of these issues which are completely outside of our control, the user accepts full responsibility for all risks of underwater application of these epoxies. Our 1.5-quart kits are very popular for residential swimming pool touch-ups, stain repairs, etc., and can be applied without draining the water.

"Hi Paul. This is Dave from San Angelo, TX. As I told you before, the underwater applied epoxy worked great. I recommend you send your product info to all pool companies and pool supply retailers or if you can find out who has fiberglass pools and send them info if they ever need it. Thanks."

"My story: We have a fiberglass pool that is 31 years old. I know they are not supposed to last that long. But this one is starting to have surface cracks (and I think more than surface cracks). We have ordered the Water Gard 300™ epoxy twice to fix them and it has worked great. That is the best stuff ever, I can’t drain my pool because I have a really high water table (the pond in my back is groundwater).

“And, I think the integrity of the fiberglass is gone. My grandkids love the pool. We are just trying to keep it together for the rest of the season, then figure out what to do."

“My name is T.R. and I live in Las Vegas, Nevada. I have a beautiful custom pool and I noticed a small area on the sidewall of my pool. I took a wire brush and tried to remove the dark-colored spot. Unfortunately, I rubbed too hard and made it worse, much worse. I contacted 10 different pool companies and each of them informed me that I would need to drain the pool to repair the spot that was getting larger by the day.

“Draining a pool with 28,000 gallons during the summer is bad enough, but fixing the plaster that had been rubbed down to the Gunite is very expensive. I needed a quick fix and there did not seem to be one! Well, I was wrong.

“I discovered a man named Paul Oman at epoxyproducts.com on the internet when I searched for plaster underwater repair and to my amazement, he told me about an epoxy that you mix in a ratio of 2 to 1 (Water Gard 300™ - available in white or light blue).

 “One last thing. Paul sent me the white at my request. I mixed a light blue paint from a hobby store and my pool looks great. This product is perfect and it is for real. Do yourself a favor and don’t listen to the pool guys. They want your business and that adds up to big bucks! Thanks, again, Paul for helping me solve this problem.”

"Hey Paul, just wanted to drop you a line. Just wanted to thank you again for your Water Gard 300™ underwater epoxy paint. As we have discussed in the past, we have a commercial steel pool, and no matter how well we prep it for paint each year, we always end up with a few rust spots partway through the season.

 “Once again, your Water Gard 300™ came to the rescue to touch up some particularly ugly rust spots this year. Thanks, again!”

—Howard From DXX Swim Club

“Just wanted to let you know that the white Water Guard 300™ I purchased to repair my fiberglass swimming pool underwater worked great!!! Just what I was looking for. The product covered more area than I expected, but I may be ordering more!!!

 “Did test spots on shallow areas and steps, and it looks like it did 31 years ago. Going to tackle the deep area next. Tested using a brush and a roller. The paintbrush worked a little better for me. Thank you so much! I will share with others!"

—Helen from L.A.

“All I can say is thank you...I have a small fiberglass inground pool with visible bare spots. With the cost of repainting (estimates of $5000) and risk of the pool popping out of the ground if it was emptied to be repainted, I looked for alternatives and found you.

 “Used the Water Gard 300™ you sent. I followed your advice and the instructions provided. There were three or four bare spots. One was about two-feet long and down to the fiberglass, very ugly. The epoxy you recommended for the job was so easy to use. Saving me money. Thank you so much.”

“Just wanted to let you know that your Water Gard 300™ pool touch-up kit was a lifesaver for us this year. We painted our swim club pool this year, and the pool paint we used turned out to be super slippery. Opening day, we had several people comment on how slippery the steps were leading into the shallow end of the pool.


“We were scrambling to figure out how we could fix that since the pool was now full of water, and then we remembered that we had bought a kit of your Water Gard 300™. After we closed that night, we mixed some of your epoxy with a little bit of sand and brushed it on the steps. It was like magic. The steps were no longer slippery, and the color nearly matched the pool paint.

“The next day, folks were none the wiser that the steps had been painted the night before, and the steps had just the right grip for safe entry into the pool. We are now over a month into the season and the paint has held up excellently. Last night, we used it to touch up some rust spots. Our pool is actually steel that had bled through the pool paint.

“We will definitely be using more of your product next year. Very Best Regards,"

“The entire pool is steel (never any issues or problems with metal pools). It is a 5-lane competition length pool. It was built in 1955. Steel was cheap and welders were even cheaper when the Koreans finished up, so they built it out of steel. When the water is out, you can still see the weld seems every 5 feet or so, even through the layers and layers of pool paint.”
