FAQ

1- WHY ARE THICK MOLDS FOR PLASTER AND ACRYLIC RESIN?
Scenography molds (THICK) -plasters, acrylic resins

A: Because the pieces they offer are thick, this makes it easier and faster to unmold them.

B: Our molds are designed to make many buildings! A large project can consume a lot of material, and large, thick parts consume a lot. It may be a good option to use cheaper materials such as plaster.

C: It is recommended that the pieces of plaster or acrylic resin be thick and strong since they are more delicate materials than polyurethane resins.
D: We can apply polyurethane resin on dry plaster to harden it a lot (see my tutorial on YouTube) Acrylic resin barely absorbs resin.

2- HOW MANY REPRODUCTIONS CAN THE PLASTER OR ACRYLIC RESIN MOLD RESIST?

A: Probably countless! The plasters do not damage the silicone. The silicone is high-quality platinum-based and very resistant to breakage, so it is very difficult to wear them with the use of these water-based materials.

1- WHY ARE FINE MOLDS RECOMMENDED FOR POLYURETHANE OR EPOXY RESIN?
Scenery molds (FINOS) -polyurethane, epoxy

A: These resins are very strong and resistant materials, so a thin piece is enough.

B: They are somewhat more expensive materials than plaster, so with thin pieces we can make good use of the material.

C: Epoxy and polyurethane resins are aggressive to silicones. Our silicone is a high-end platinum base and, although later, it is also affected.

Because of that, I have tried to make the molds as light as possible so they can be cheaper.

2- HOW MANY COPIES CAN THE MOLD RESIST USING POLYURETHANE OR EPOXY RESIN?

A: Platinum-based silicones like this one can resist up to 50 prints on aggressive materials. Molds containing large parts are more affected than those containing small parts.
The molds of thin pieces such as skeletons, soldiers, decorations etc, resist many copies!

B: Silicone-based mold release spray can be used to hydrate molds after each pour and when storing them.

C:We recommend letting large molds cool between pouring.

3- IS IT NORMAL FOR POLYURETHANE RESIN TO SET SO QUICKLY?

So. Normally these common polyurethane resins offer us 2 minutes of work. We must do it fast. Large amounts of resin set much sooner than small amounts. For large loads, it is better to do it several times.

B: Don’t waste a lot of time mixing the components. Doing it for 5 to 8 seconds is enough.

C: The resin spoils once opened, try to spend it while its properties are good. Protect the can from light, heat and moisture.
