Product Instructions

Step 1. Prepare for Mixing

Gather your epoxy resin, mixing supplies, and personal protective equipment. We recommend at the very least using nitrile gloves, safety glasses, clothing to protect from spills. Be sure to use epoxy resin in a well-ventilated room or use an air-purifying respirator.

Step 2. Pour Epoxy Resin into a Mixing Container

After determining the amount of epoxy resin you will need, measure your desired amount of epoxy resin at a 1:1 ratio by volume into a graduated mixing cup. Pour the resin first, allow it a moment to settle, and then follow up with an equal amount of hardener.


For best results mix a minimum of 2 fluid ounces (60ml) of epoxy resin and hardener. Mixing less than 2 ounces increases the chance of the mixing ratio being off and causing issues during the curing process.

Step 3. Mix Thoroughly for Four Minutes

Mix the two parts together for a total of four minutes. Be sure to scrape the bottom and sides of the container while mixing so that there is no un-mixed epoxy resin. Aggressive mixing can introduce excessive air, stir slowly but thoroughly. Continue to stir until the epoxy resin no longer has ribbons and returns to clear.

Step 4. Apply to Surface

Apply the epoxy resin to your surface immediately after mixing. You can do this by using your gloved hand, a foam roller, a brush, a trowel, and so many other tools! Make sure that epoxy resin completely covers the surface before moving to the next step. If you do not apply enough epoxy resin it may pull away from the edge. If you apply too much epoxy resin it can drip off or run to one end depending on the surface.

Step 5. Use a Torch or Heat Gun to Remove Trapped Air

Quickly sweep a propane torch or heat gun across the surface being sure to keep the flame 6-8 inches away from the surface. Do not overheat the epoxy resin or hold the heat in one spot for too long. We recommend heating the epoxy resin only during the working time, do not apply heat once the working time has passed. After eliminating bubbles allow the epoxy resin time to cure in the appropriate environment (listed in Technical Data below).


Ensure that you are working in a well-ventilated room or using an air-purifying respirator.

Always the best!

Best ever

This is the only kind I use, and I will not go back to anything else.

Jasmine Rivera

I absolutely love KS LS UV, it works perfect for my thinner pours. I just have to remember to prep everything before using, so I don't get a flash cure. But I love how I can take things out of the mold in only 4 hours. Makes some projects just go faster.
