How much epoxy do I need? Find out the quantity of resin you need. How much resin will you need for a single coat ? What coverage is allowed with your kit of resin ? Be an informed resin buyer and do your homework first. The calculation for determining the amount of epoxy is a simple volume calculation. You simply multiple the Height x Lenght of the pour by the average width of the pour and then convert to litres. When calculating the average width of the pour, we measure the width every 6 inches along the entire work piece and then divide by the total number of width measurements you took to determine our average. This will give you a precise estimation but recommend to add 10-15% to be sure not to run out of material and have to go back to make a new mix.
How much epoxy do I need? USE OUR RESIN CALCULATOR (RESIN CALCULATOR)
I/ Calculate the volume of resin to be cast
1/ Find out the volume in cubic inches or in cubic centimetres
Before embarking on your project, you should determine what the dimensions of your mold are and what quantity of resin you need to pour. Make sure your dimensions are given in one single unit.
Length in inches x width in inches x thickness in inches = volume in cubic inches
Length in cm x width in cm x thickness in cm = volume in cubic centimetres
2/ Find out how much litre you can pour in such a volume
Volume in cubic inch x 16.38 ml /1000 = Litres
*NB: 1 cubic inch = 16.38 ml
Volume in cubic centimetres /1000 = Litres
Remember to allow at least 3 % more of product to compensate for losses
II/ Calculate the coverage allowed by one coat
1/ Find out the quantity of resin contained in your kit in millilitres
If you only know the weight of your kit of resin, you will need to know the specific gravity of the product.
Example 1: 1 kit of our product T-3056 in 4 kg with a specific gravity of 1.08
In this kit you have 4/ 1.08 = 3.703 litres or 3703 millilitres.
Example 2 : 1 kit of Chill Ice 1 format 1.5 Litres = 1500 millilitres
2/ Find the quantity of resin in cubic inches
Prerequisite : you need to know a theoretical thickness of one single coat.
With a product like Chill Ice 1 applied in a theoretical layer of 1/4 inch thick, the quantity of resin in one square foot* is :
12 x 12 x 0.250 = 36 cubic inches on 1 square foot
*NB: 1 foot = 12 inches
3/ Find out the quantity of resin on a square foot.
One cubic inch equals 16.38 millilitres
36 x 16.38 = 589.68 millilitres per square foot
Allow for at least 3 % more of product to compensate for losses , thus a total amount of = 607.37 millilitres
4/ Which format do you need ?
With a 1.5 Litre format that equals 1500 ml, you can coat.
1500/ 607.37 = approx. 2.47 square feet.
