Do You Know How Much Epoxy You Will Need?

So, how much epoxy is needed? Before you start your project, you have to make sure you have the right amount of epoxy for the job. If you do not have enough epoxy, you could find yourself stuck in the middle, wondering what you are going to do next as you are staring at a job that is half-finished. On the other hand, if you have too much epoxy, you may have spent more money than is actually necessary. Therefore, how much epoxy do you need?

Use a Calculator

First, there are helpful online calculators that can help you make the right decision. That way, you can figure out how many ounces of epoxy do you need or how many gallons you require, as this can make the job easier.

The Formula: Diameter and Thickness To Cubic Inches

Before we get started, it is important for you to understand how the formula works. If you are coding a basic rectangular surface, the formula is straightforward.

Measure First

First, you have to measure the piece. You need to know how long it is and how wide it is. In addition, you also need to know how thick you want the epoxy finish to be. The goal of using this formula to calculate the cubic inches you need to cover.

What Is the Formula for Epoxy Resin Thickness? 

Then, you need to convert cubic inches to US fluid ounces. You divide this number by 1.8. 

Finally, you will take this number and convert it to gallons. 2 converted to gallons, you have to divide by 128. 

If you are working with a round table, you may need to use a slightly different formula. You need to calculate the radius and then convert this to cubic inches before you can convert it to fluid ounces. Then, you can convert this to gallons if you desire. 

Is This Calculation Always Accurate?

The calculation is as close to perfect as it can get. On the other hand, keep in mind that there are extraneous factors that could play a role. For example, during the mixing process, you may lose some epoxy. Or, when you pour the epoxy, you may lose a little bit during this step as well. Be sure to think about these losses, as they could impact the final project thickness. You don't want to run out of epoxy in the middle. Therefore, you may want to add five to ten percent to the total number of gallons you are going to use.

How Much Epoxy Do I Need Per Square Foot?

The amount of epoxy you need per square foot is going to depend on how thick you want your epoxy coating to be. If you want a thicker coat, you will need more epoxy per square foot. On the other hand, if you want a thinner coat, then you will need less epoxy per square foot. In general, if you want your coat of epoxy to be an eighth of an inch thick, which is common, you should be able to get 12 square feet out of every mixed gallon. Keep in mind that if you have 14 or 18 square feet, you will need more epoxy to reach the desired thickness. This should help you figure out how much epoxy you need if you already know your area. 

Epoxy Coverage: Do You Need a Footage Seal Coat Coverage?

There are situations where you may want to add a seal coat as well. If you are working with a porous material, such as wood, then you may need to apply a seal coat. A seal coat is important because it will prevent air bubbles from coming out of the material when you apply the flood coat.

If you are planning on applying a seal coat, apply a thin layer of epoxy to the surface. Then, a few minutes after applying a seal coat, take a look at the material. If there are areas that have already absorbed the initial seal coat, then you need to apply more epoxy. Be sure that you provide plenty of time for the seal coat to cure appropriately. Then, you can go back and apply to flood coats later. 

Tips for Working with Epoxy Resin

If you are working with epoxy resin, there are several steps that you should follow. Some of the most important tips that you need to follow to get your floor correct include:

  • Make sure that you only deep pour your epoxy resin into a clean metal, plastic, or unwaxed cup.
  • Do not use glass or film mixing cups because epoxy can dissolve many of these materials, ruining your epoxy in the process.
  • Always dispense more epoxy than is recommended when you are mixing it so that you can make sure the mixing ratio is accurate.
  • Remember that the epoxy needs to be completely and thoroughly next in order to obtain a proper cure.
  • Do not lift or with the epoxy during the mixing process. Otherwise, you will simply add air bubbles to the mixture.
  • Remember to scrape the sides when you are mixing. Otherwise, the unmixed material is going to lead to an uncured, wet, or sticky spot.
  • If you are planning on using thickening agents, pigments, or tents, dispense them into the mixed epoxy and make sure they are mixed consistently before you are finished. 
  • After you are done with the mixing process, poor and apply your epoxy immediately. Do not allow the epoxy to sit in the mixing cup. 

Following these tips will lead to a successful project. 

It is possible that you may encounter a few problems as you start to cure the epoxy. Usually, these issues come back to mixing the resin and hardener at the wrong ratio. If you do not do a good job in mixing the two components together, you are simply setting yourself up for failure. And other cases, some outside contaminant could ruin the epoxy. If you do not carefully take a look at the materials you are using, it is easy for an outside contaminant to get involved. Then, this contaminant is going to end up in your final project, leading to significant issues.

As you start the process of mixing you are two components together, it is important to make sure that you store them thoroughly. Particularly if there are cooler temperatures involves, you may want to add an extra minute to the serving time. After this, make sure that you scrape the sides and bottom of the pot thoroughly. Be sure to use the flat end of the mixing stick, as you can use this to reach the inside corner of the pot. That way, you do not have to worry about missing a spot. Remember that the curing process is going to lead to heat generation.

This is another reason why you need to make sure that you stay away from class and foam mixing containers. They are not going to be able to stand up to the heat and this could lead to significant issues down the road. Think carefully when you are mixing the epoxy. Make sure that you set yourself up for success down the road. If you follow these tips carefully, then your project should lead to a successful result. If you need help with your epoxy, do not hesitate to reach out for help from a trained professional. It is always better to make sure that you get your project done the right way on the first attempt rather than to fix a mistake.

How Much Epoxy Do I Need Calculator?

Ultimately, if you are going to be using epoxy resin, you may want to use a helpful calculator. Keep in mind that calculators are going to assume that you are working with a certain shape. No matter what type of shape you are working with, you need to make sure you calculate the area appropriately. If you do not make the appropriate area calculations, the coverage calculator is going to be thrown off. 

In Conclusion: Use the Right Amount of Epoxy

In the end, you want to make sure that you use the right amount of epoxy. There are a lot of people who have a question or two about the mix ratio, particularly if they are working with flood coats. Be sure to check your email address after placing orders so that you know you have the right amount of epoxy coming to you. You also want to take your time as you are applying epoxy along the length of the floor. When you are taking a look at the edges of the floor, you don't want too much heat build-up. Otherwise, coding epoxies may be a bit off. Think about how inch thick you want your epoxy to be when you are trying to figure out the amount of epoxy needed.
