how much epoxy do i need to cover my artwork

resin coverage for a paintingYou have an art print you want to give a clear, glossy finish or perhaps you created an awesome painting of your own you want to cover in resin. You might find yourself asking how much epoxy do I need to cover my artwork? It is important to know this number to make sure you use enough resin to give it an even, shiny look, but not so much that you end up mixing more than you need and wasting resin

Before we get into the numbers, there are a few details you need to understand:

You need to use a doming resin for covering artwork.  Doming resins self-level to a depth of 1/8” inch.  Casting resins however, do not self-level and are not suitable for covering artwork.  This article explains the differences between doming resin and casting resin.

Don’t skimp on the amount of resin.  I get it. The stuff is expensive, especially when you are mixing volumes large enough to coat a painting. But, when you don’t use enough resin, it pulls away from the surface leaving voids or ‘fish eyes’.  If you mix a little more than you end up needing, have a few projects ready to go.  Here is a project I like to do with leftover resin.

Make sure your surface is clean and dry.  If you have created artwork that used an oily substance or perhaps the paints aren’t dry, your resin may not cure or may cure with sticky spots. If possible, wash the surface with soap and water or clean with isopropyl alcohol and allow to dry before coating with resin.

Now that you know that, it comes down to basic math:

You will need to multiply the length (in inches) times width (in inches) times 0.125 (which equals the 1/8 inch depth we talked about above). This is the volume of resin you need in cubic inches. Multiply this number by 0.554 to know the number of ounces of mixed resin (resin plus hardener) you need to cover your artwork.

But if you are anything like me and hate the idea of doing math, we can help. This resin calculator does the math for you in either ounces or milliliters.  This calculator is helpful if you are pouring in a depth other than 1/8 of an inch or are pouring multiple coats.  Here’s how it works:

So know that you know how much epoxy you need to cover your artwork, how do you do it?  This video shows how:

    1. For your hands, you should only use soap and water. Do not use solvents. If you have sticky resin on your hands, use a pumice soap.

  1. Once you have the resin calculated, how do you know how much of each part of the mix to use to get the number you calculated. You got 9.97 oz. I’ve never done this before. thanks

  2. I’ve been reading a lot of articles since I want to start working with resin. I’m not so much interested in making jewelry, but things like table tops, and wood working. Before I tackle any big projects what are some tips you have for getting used to mixing and working with resin? What types of resin would I want to be working with when using larger quantities?

  3. I’ve just recently started this new obsession and have been making coasters using tile squares. The problem I’m having after I’ve done the acrylic pour and it has cured for a few days is when I pour the resin it covers nicely but then pulls away from the edges. I’ve tried tape around the tile but then I have to sand it later because it leaves a ridge. Do you have any suggestions?
