What is acrylic resin?

Acrylic resins are a type of synthetic, odorless, and non-toxic plaster that can be used at home without a mask or gloves.

This type of polymer will be mixed with water and poured into a mold to create a shaped object. The resulting product is strong, durable, and resistant to water and UV light. It is commonly used in a variety of applications, such as wargame scenery, figures, sculpture, jewelry making, prototyping, and other decorative items.

Once dry they have a hardness similar to porcelain and at the same time much higher than traditional plaster.

How can I colour acrylic resin?

Simply add a few drops of acrylic paint or earth pigment during processing.

If too much pigment or liquid dye is added, it may affect the hardness or its drying time.

How to increase the hardness of acrylic resin?

This moulding material takes about 30 minutes to set, but it needs at least 24 hours to reach its maximum hardness.

The normal ratio is 3:1, but if we increase the amount of resin by 4:1 we will obtain pieces that are a little more resistant.

Another way to reinforce these pieces obtained with silicone moulds, would be to apply a thin layer of polyurethane resin with a brush in order to create a super resistant protection on the outside of the piece.

How long does it take to dry?

It has a drying time of 30 minutes depending on the ambient temperature, reaching its total drying time 24 hours after its application.

A domestic oven could be used to speed up the drying time.

Can I carve the acrylic resin?

Yes, it is perfectly possible to carve the pieces with a modeling hobby knife.

If the piece is very thin, an attempt to make a hole, for example with a modeling drill, could break the piece. This should be done with great care.

What is the shrinkage rate?

This material has no shrinkage whatsoever, so once you have removed the piece from the mould, it will not shrink and will keep its shape and size forever.

If any excess or burrs are generated, they can be removed with a modeling cutter.

If the pieces you are working with are elements that must fit with other pieces, it is highly recommended to use sandpaper to even and flatten completely the back of all the pieces obtained from the mould. In this way, all the pieces will fit together.

What is the best paint to paint with?

Acrylic paint is undoubtedly the best and most recommended type of paint for painting this type of moulding material.

You can really use any type of paint, once the material has dried completely, but the best will always be the least toxic.

Green Stuff World hobby paints are especially good for this purpose because of their excellent gripping properties.

How to demould synthetic resin?

As a non-aggressive type of resin, it does not damage silicone moulds and is very easy to de-mold without having to use any demoulding agents. Simply bend the silicone mould a little to remove the part. Parts that are not fully cured may have a point of weakness and could create a break in the part.

Where to buy Acrylic Resin?
