If any unmixed material remains on the side of the container and falls onto your surface while pouring, it will leave an uncured wet or sticky spot.

This reduces the chances of any resin or hardener rich areas. Mix in one cup, then pour into another one and continue until it is completely mixed. It is strongly recommended to use the 2 cup mixing method. Always scrape the bottom of the mixing cup and the sides ensure a good mix. MIXING: The epoxy needs to be completely and thoroughly mixed for a proper cure, but avoid lifting and whipping, as it adds air bubbles into the epoxy. Do not mix or apply the next stage until the previous pour has started to harden, the exothermic reaction has occurred, and it has started cooling down. For larger pours, divide the required amount of epoxy by the maximum pour amount. The manufacturer bases this on giving the user the greatest amount of working time, while avoiding generating too much heat from slab pours, or castings. Do not dispense more than the manufacturer’s maximum recommended amount of epoxy. This will help ensure that the mix ratio has been dispensed accurately, promoting the best possible cure of the epoxy. Make sure that you are mixing more material than the manufacturer’s recommended minimum of epoxy. Glass mixing cups are not recommended due to the potential danger from exothermic heat build-up from the reaction. DO NOT use glass or foam mixing cups as the epoxy can dissolve many types of foam materials such as styrofoam. Only dispense the epoxy resin and hardener into a clean plastic, metal, or unwaxed paper mixing cup. Allow the seal coat to cure prior to applying the flood coats. Apply more epoxy to areas that have absorbed the initial seal coat. A few minutes after applying the seal coat, observe the sealed material. To apply a seal coat, brush on, or apply a thin layer of epoxy to the surface. This prevents air bubbles from coming out of the substrate while the flood coat is applied later. Is a Seal Coat Needed?Ī seal coat should only be needed for wood or otherwise porous materials. Then convert cubic inch volume to ounces, convert ounces to gallons, and pad by 5 to 10% percent. If you already know the area for a given surface, just multiply that by desired coating thickness (remember to convert feet to inches and fractions to decimals first) to get volume. I Already Know The Area: How Much Resin Will I Need?

Remember, these formulas don’t address epoxy needed to cover the edges or any losses from mixing or pouring. To convert ounces to gallons, divide by 128. Divide by 1.805 to convert cubic inch volume to US fluid ounces. To calculate volume in cubic inches: (radius squared) X pi (or, 3.14159265) x (desired epoxy coating thickness). Divide the diameter by 2 to calculate the radius. For a round surface, you will need to measure the diameter. To convert cubic inch volume to US fluid ounces, divide by 1.805. Multiply these 3 measurements together to calculate the volume for the top of the table (or bar, or countertop) in cubic inches. You’ll also need to know how thick you’d like the epoxy finish to be. You’ll need to know length and width in inches. When it comes to coating a rectangular surface, the basic formula for table top epoxy resin coverage is quite simple:įirst, measure the piece.

What Is The Actual Formula For Epoxy Coverage? We aren’t telling you that to trick you into purchasing more resin than you need! It’s a lot better to have a little extra on-hand than to run out in the middle of a project and have to start all over. Most common table top and bar top epoxies provide approximately 12 sq feet per mixed gallon coverage at 1/8″ thickness. For most epoxy applications, 5-10% extra should be added to account for the inevitable wasted epoxy that stays on the stir stick, or stays in the bottom corners of the mixing cup, or accidental drips. And, you’ll probably lose a little to mixing or overflow. How are you handling the edges of the surface? You will need more if you are allowing epoxy to run over the edges, compared to building a dam or wall. Porous surfaces that require a seal coat will increase the amount of resin needed. It’s best to consider any epoxy coverage calculator a good starting point, but there are other factors and variables that might impact how much epoxy you will need.
