Measuring the amount of epoxy you need for your project is a fundamental part of planning. You don't want to feel like you've purchased far too much, but having too little can be a major issue if you're forced to order more partway through curing.
Today, we'll be covering how to determine the amount of epoxy you need. We'll explain each of the things you must consider to get an accurate estimate, and then we'll talk about how to properly measure for your resin batch during the actual project.
Measuring the amount you need when planning your project
To quickly get a rough estimate, check out our Epoxy Coverage page.
Let's start with figuring out what you need in total for your project. Here are the factors that will help you determine what you need:
What's the total surface area of your project? If you're just dealing with rectangular shapes, this is pretty easy to figure out—just length multiplied by width for each rectangular section. For something a little more complex that you're having trouble calculating, don't be afraid to round up. It's better to have too much than not enough.
How thick do you want the epoxy finish to be? Primaloc Epoxy self-levels at 1/8 of an inch, which is usually more than enough to protect the substrate. If you want something thicker than that, you can do multiple layers, but you'll need more epoxy.
Does your project include edge guards or rails? If not, you may want about 20% additional epoxy to compensate for dripping.
Will you apply a seal coat? We highly recommend applying a seal coat of epoxy before pouring on a flood coat.
Seal coats are thin, manually-applied layers of epoxy that seep into the pores of a surface and push air out. This massively reduces the number of air bubbles that appear in the final flood coat, making removal by heat gun or torch much easier.
Once you have your answers to these questions, it's time to calculate the total amount of epoxy you'll need.
Calculating the total amount
Most epoxy projects will include two coating phases:
- The seal coat phase, where you seal the substrate surface to remove air.
- The flood coat phase, where you apply the full epoxy finish.
For seal coat coverage using Primaloc:
- 1 qt. of Primaloc Epoxy Resin covers 12 sq. ft. of surface area.
- 1 gal. of Primaloc Epoxy Resin covers 48 sq.ft. of surface area.
For flood coat coverage using Primaloc:
- 1 qt. of Primaloc Epoxy Resin covers 4 sq. ft. of surface area.
- 1 gal. of Primaloc Epoxy Resin covers 16 sq. ft. of surface area.
As you can see, the seal coat really doesn't require much. It's just a very thin layer to remove air and to prime the substrate for the proper flood coat.
You can use these numbers to figure out how many quarts or gallons you need to complete your project.
How to measure an individual batch of epoxy resin
During the epoxy process, you'll need to mix up batches of epoxy to complete your seal coat and flood coat.
We highly recommend the use of measuring containers which feature labels on the side. You can find good ones in our store on the following pages:
Primaloc Epoxy is a two-part epoxy. It comes in two components, resin and hardener, that must be mixed together in a 1:1 ratio (half resin, half hardener).
For proper curing, you need to make sure you add these components them in equal amounts to your batch.
For instance, to make a quart-sized batch of epoxy, you would use 1 pint of resin and 1 pint of hardener. This would total a single quart once combined.
For measuring a seal coat: We suggest using smaller batches using our 1 Quart Mixing Containers, as a seal coat spreads thin and is applied manually, which can take a little longer than just pouring.
For measuring a flood coat: The size of container you need will vary, but you should never mix more than a gallon at once, as it becomes difficult to get a smooth blend at higher volume. For this we suggest our 5 Quart Mixing Container, which has plenty of room.
Additionally, for gallon-sized resin batches, you can use a drill with a mixing bit attached to make blending easier. We have a high-quality Mixing Drill Bit in our store. It's reusable and doesn't need to be immediately cleaned after each batch.
