Prop Making

Prop Making Techniques

Weapon props, such as knives, hand tools, and guns may be cast in FP series casting rubber. FP series rubbers hand in hardness from 25A to 90A. In this video we use FP-90 and Blue Steel Powder Pigment to cast a realistic prop wrench. UV-100 additive may be added to casting rubbers to help reduce the effects of UV light on cast rubber parts.

Foam is a very popular material for prop making. We offer both rigid and flexible foam systems. In this tutorial we explain some basic use tips for casting rigid foam into a silicone mold. For this cast we used our economical, Rigid Casting Foam and cast it into a soft silicone mold. PolyColor pigments can be used to cast colored foam parts, Rigid foams can also be used to back hollow resin casts, like ArtKast Pourable rotationally cast parts.

A common art department problem is creating spills and puddles that can be easily cleaned up or moved, or repeated days later. FP-40 casting rubber can be used to pour Polyurethane "blood" puddles and other "spills." FP-40 is naturally dark amber but may be pigmented with transparent Solvent Dye or PolyPig colors. UV-100 may also be added to protect against UV damage.


In this next video we use PlatSil Gel-25 mixed with PlatSil Hardener to make a gun mold. We then used TC-804 Jet Black to make a prop replica of the original. The same mold could also be used to cast PT Flex Rubber copies.
