How much resin do I need?
How to 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 !
I/ Calculate the volume of resin to be casted
1/ Find out the volume in cubic inches or in cubic centimeters
Before embarking on your project, you should determine what are the dimensions of your mold 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 centimeters
2/ Find out how much liters you can pour in such a volume
Volume in cubic inch x 16.38 ml /1000 = Liters
*NB: 1 cubic inch = 16.38 ml
Volume in cubic centimeters /1000 = Liters
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 milliliters
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 liters or 3703 milliliters
Example 2 : 1 kit of Chill Ice 1 format 1.5 Litres = 1500 milliliters
2/ Find our the quantity of resin in cubic inch
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 inch on 1 square foot
*NB: 1 foot = 12 inches
3/ Find out the auantity of resin on a square foot.
One cubic inch equals 16.38 milliliters
36 x 16.38 = 589.68 milliliter 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 Liter format that equals 1500 ml, you can coat
1500/ 607.37 = approx. 2.47 square feet.
