How to Mix Epoxy Resin


Step 1. Measure Surface Area

Calculate the amount of epoxy resin you will need for your project.

 

TUMBLERS

An easy way to estimate the amount of epoxy resin needed for a tumbler is to do 1ml per ounce of cup size. For instance we will mix 20ml per 20oz Skinny Tumbler.

 

SMALL PROJECTS

1ml per square inch

Measure both the Length and Width in inches. Length x Width = Square Inches

 

LARGE PROJECTS (Countertops, Tables, Bartops)

3oz per square foot

Measure both the Length and Width in feet. Length x Width = Square Feet

 

Mix at least 2 fluid ounces at a time to ensure your mixing ratio is correct.

 

 

 

Step 2. Pour Epoxy Resin into Graduated Mixing Container

Starting with the resin (Part A), pour to the mark on the container based on the mixing ratio of the product. After pouring the resin into the mixing container, allow a moment for it to settle.

 

Once the epoxy resin has settled, add an equal amount of hardener (if mixing ratio is 1:1 by volume).

 

Be sure to measure as closely as possible to ensure that the epoxy resin cures properly. Adding extra hardener will not cause the epoxy resin to be harder.

 

EXAMPLE: To mix 4oz total of a 1:1 ratio by volume epoxy resin, pour 2 fluid ounces of resin followed by 2 fluid ounces of hardener.

Step 3. Thoroughly Mix Epoxy Resin

Using a stir stick, mix the epoxy resin thoroughly for four minutes. Be sure to scrape the sides and bottom of the container while mixing, and ensure that the stir stick reaches to the bottom of the container. Mix slowly to minimize the amount of air that is introduced into your epoxy resin mixture.

 

It is best to continue mixing for four minutes, but be sure that there are no ribbons left in the epoxy resin as this is a clear sign that there is unmixed product still in the container.

 

Unmixed epoxy resin can cause soft spots or stickiness in your final product? Resin can easily stick to the container, so it is very important to scrape the sides and bottom of the container.

 

Silicone and stainless steel stir sticks are an excellent alternative to wood. They are non-porous and re-usable.
