Resins are essential in boat building and repairs and are used for base coat applications and saturating composite fabrics. Thus, it’s crucial to use only premium- quality laminating resins for your projects.
If that's what you're looking for, then we have what you need — a resin that’s easy to apply and allows for strong adhesion. Plus, since it's a general-purpose product, its use isn't just limited to boats and watercrafts.
Get top-notch results for your construction and repair jobs with Polymer World’s Polyester Resin with MEK-P Hardener with our chopped strand mat.
This fast-wet-out laminating resin can be applied to any fiberglass surface. This includes target areas on boats and yachts, as well as surfboards and kayaks. They can also be used for car and motorcycle parts and even plumbing fixtures like fiberglass bathtubs.
Tired of resins that cure very quickly? Not a problem — our polyester resin stays tacky and won't cure as rapidly as others. You don't have to worry about it hardening while you're in the middle of the job. When it does cure, it results in secure adhesion, ensuring that every layer you stacked is well-bonded.
What's more, our 1-gallon jug of laminating resin comes with a 2-fl oz bottle of MEK-P catalyst and our chopped strand mat. You can adjust the amount of hardener you add to the resin to control the gel time. When handling this resin, we recommend doing so in temperatures between 70-95°F for optimal results. When not in use, we suggest storing it in areas with temperatures below 77°F.
Here are more details about our laminating resin:
- Easy to mix, superb consistency
- Doesn't contain wax
- Marine-grade and waterproof

Product had a good long working time. It is a little runner that I expected but once fiberglass is saturated, it holds in place. Smell of product is very strong. Glad I bought a new respirator. The amount of hardener given seems a little short and will have to buy extra. Maybe it is the perfect amount if you mix the whole gallon at once but I will be doing around 10 mixes for my subwoofer enclosure. I like the fiberglass included because it doesn't make your skin itch.

Used it to reinforce a weak floorboard section in a 50 year old car. There were a few pinholes showing through, but floor was basically sound. So I sanded the interior side of the floorboard down, and applied 3 separate layers of resin and fiberglass mat, to seal, strengthen, and protect the floor. I used a stiff, cheap disposable "chip brush" to brush the resin into the fiberglass mat, and press the mat down. Just lay the mat down on the surface first, and brush the resin through the mat. Resin and hardener work fine, unless it is a really cold day... Then, you must use a heat gun, or space heater to get the temperature up to normal room temperature, so that it will harden. Because the kit I ordered uses the random strands of glass (fiberglass mat) it is much stronger than the fiberglass cloth. The amount of hardener included, was plenty enough to harden the gallon of resin. Just use the amount of hardener recommended, don't try to over catalyze the resin by using too much hardener. I used a disposable plastic measuring cup, to measure out each resin pour. Be sure to have good ventilation, and a pair of disposable gloves are a great idea.

I needed to repair my fiberglass steps which were cracked after someone (no longer a friend) used a sharp blade to chop off ice - big crack. The directions are clear and easy to follow. Be advised that the resin is clear and the fiberglass cloth is white so you see it when it's dry. Work fast and make sure you have gloves and disposable pans and brushes on hand for the job. I was able to paint it after it dryed and it is SOLID. If you intend to paint the surface after you're done - great. You can be sloppy but if you're not, then look up adding color to the resin to help with the blending. If you need, do some tests sites with the color to get a good blend. They give you a generous amount of fiberglass cloth and it streches when applied. Overall, it was worth the effort and learning curve cause our stairs look better than before - he guy that broke them is no longer welecome.

Worked great for building my subwoofer enclosure with tons of material and at half the price or less than local stores
