What is the mixing ratio for epoxy resin?

Typically, this is 1 : 1 or 2 : 1 between resin and hardener, but there are also much more complicated ones such as 100 : 45. You can usually find the details on the packaging or containers. The mixing ratio has to be very precise, otherwise the epoxy resin will not harden or it will not work optimally.

How do you find the ratio of epoxy resin and hardener?

To measure 105 Resin and 207 Special Clear Hardener or 209 Extra Slow Hardener by volume, combine three parts epoxy resin with one part hardener (by weight, 3.5 parts resin-1 part hardener).

Do you mix epoxy resin with hardener?

Mix longer for larger quantities. Be sure to scrape the sides, corners, and bottom of the container several times during mixing. This will ensure that all the hardener is thoroughly mixed with the epoxy and should prevent the resin from having an improper cure. Make sure to scrape both sides of the mixing cup also.

Can you over mix resin?

At times our machines may over-pour the resin or hardener, which can cause you to get more product than normal. Adding too much of either resin or hardener will alter the chemical reaction and the mixture will not cure properly.

What happens if you put too much hardener in resin?

Adding too much of either resin or hardener will alter the chemical reaction and the mixture will not cure properly.

Can I use a hair dryer on resin?

In short, YES a torch is the best tool to get rid of bubbles in epoxy resin. A hair dryer or heat gun doesn’t get hot enough to remove bubbles efficiently and can blow dust all over your wet resin.

Why does my resin have tiny bubbles?

Porous, organic materials like wood, leaves, fabric and even paper can “breathe” air. When you cover these materials with resin, the air bubbles release into the resin in the form of bubbles, sometimes hours after you have poured and torched.

What happens if you add too much hardener to epoxy?

Off ratio: Too much or too little hardener will affect the cure time and thoroughness of the cure. Remove epoxy. Do not apply additional material over non-curing epoxy.

Can I use paper cups to mix resin?

50 Graduated Paper Cups Perfect for mixing small batches resin, paint, stain, epoxy from 1 to 3 ounces. Cups are are wax coated. They are sturdy and smooth on the inside to help with complete mixing. They are flexible enough to make pouring easy.

How to mix epoxy resin for the first time?

What’s the best way to mix hardener and epoxy?

How big of a piece of artwork do you need to mix epoxy?

Let’s say you have a piece of artwork that is 1 feet x 2 feet ( 12” x 24” ). Total combined epoxy resin required is 10oz: 5oz of resin and 5oz of hardener. Test by starting pouring 5 oz of resin into the mixing cup, then 5 oz of hardener ( total 10 oz ).

Can you measure the volume of epoxy resin?

Note: Make sure to double check the maximum margin of error on your system. You can also measure your epoxy resin by volume, just make sure you have mixing cups with well-marked graduations. Determine as close as possible the amount of mixed material that the application requires.
