How To Make Resin Casting
Step 1: Measure How Much Water the Mold Will Hold
Pour 1/8 cup of water into 3 disposable plastic cups. Mark the water line with a pen. Our mold will hold about 1/2 cup so we will repeat the mixing process several times.
Step 2: Mix the Resin and Pour Into the Mold
Spray mold with cooking spray. Wearing safety gear and working in a well-ventilated area, preferably outside, measure out 1/8 cup of resin and add 6 drops of the hardening catalyst. Mix with a craft stick thoroughly according to manufacturer directions. Pour into the mold and let it harden to a jelly stage, about 25 minutes. Throw the cup and craft stick away in a trash can outside.
Step 3: Make the Next Layers
Now, lay your item to be sealed on the jelly hardened resin. Repeat the process. Measure another 1/8 cup of resin, but his time only add 4 drops of the catalyst. Mix and pour into the mold. Let it set another 25 minutes. This is when you can add a written saying. Be patient, mixing resin so that it sets right can be tricky so start with an easy object to encase. Repeat the same measurements one more time. Do not overfill the mold. In all, our mold took 3 layers of resin to complete.
Step 4: Let the Mold Cure for 24 Hours
The top of the mold should "click" hard and not be tacky to the touch. If you have trouble getting the mold to release, run it under hot water and carefully push it out. Let it stand in the open air for an hour or two. If you touch it immediately, it may pick up your fingerprints and become cloudy.
