With over 1,600 positive reviews, Liquid Art Ultra UV is our best-selling product for good reason.

Perfect for creating epoxy tumblers, coating canvases, or any other project that requires superior UV resistance, Liquid Art Ultra UV contains our Ultra UV inhibitors - hindered amine light stabilizers that protect against the harmful effects of UV rays. Unlike other tumbler epoxies on the market, Liquid Art Ultra UV has been rigorously tested in a QUV machine and has shown up to 10 times longer lasting clarity compared to the regular Liquid Art formula and similar competitors' products.

But Liquid Art Ultra UV isn't just for tumblers. Its versatility and long working time make it a top choice for any artwork or DIY project that demands the highest level of clarity and durability. And with a mixed viscosity of 4600 cP, it's thick enough to stay put while still flowing smoothly and evenly over any surface.

Best of all, Liquid Art Ultra UV cures without the need for a UV light. So whether you're a seasoned artist or a beginner looking to bring your creations to life, Liquid Art Ultra UV is the clear choice for professional-grade results that will last a lifetime.

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.

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.

My Favorite Epoxy

I’ve been using Liquid Art Ultra UV Resin for years on my tumblers. It works well in the warm conditions I live in here in Arizona. I would highly recommend this brand.


I really love KS resin, it really has a nice shine and is easy to work with. I’ve had horrible skin reactions to other resins, but not this one. Love it and it will always be my go to for resin projects.

Friendly Resin

With learning to use resin I have found that Ksresin has it all. Work friendly, heat resistant, less bubbles and a gorgeous finish. It’s great for coasters as well as canvases and cradled wood boards. Love it!

Smooth as Silk

Love this resin, very easy to work with, little to no bubbles and produces a high sheen. Beautiful clear finish. I wish it came in a two-part epoxy, handheld pen that you could use for extra fine work as I need more work time before it sets up, but overall a great product.

I just opened my gallons couple of days ago and it is coating terrible. Looks like little indents all over cups. Room is heated and I measure equal amounts. Never had problems til now. Not sure if something changed but it has really caused me some problems. I even started over on tumblers and pens to make sure I did it all correctly and did the same thing. I've sanded and coated them couple of times and it does the same thing. I'm really disappointed as this was my fav for the last several years.
