A is resin; B is hardener. This splits a total mixture. It does not convert weight to volume or calculate how much hardener to add to resin already measured.

1 : 1 by volume

150 ml A
+ 150 ml B

Use the ratio for your exact formula and kit revision. Never change the ratio to speed up curing.

Use the result with the right context.

Quantity is not a batch limit

A project can need more mixed resin than the manufacturer allows in a single container or layer. Plan separate stages where required.

Understand the quantity estimate →

Ratios depend on the formula

Keep resin A and hardener B from the same compatible system. Use the specified measurement basis; grams and milliliters are not interchangeable.

Record your conditions

Note the actual room temperature, batch size, product revision and cure observations. Keep a backup of browser-local project notes.
