Product Information
Full details
West Liquid Moulding Latex is an ideal solution for hobbyists, artists, and model makers looking to create precise, reusable moulds for small to medium-sized projects. Its primary benefit is the ability to form a highly flexible, peelable skin that captures intricate details with accuracy. However, users should note that the product requires an overnight curing period and must be used in a well-ventilated space to handle the fumes produced during the air-drying process.

FAQs
How many layers should I apply?
For most projects, applying 5 to 8 thin layers is sufficient to create a durable, peelable mould.
Can I speed up the drying time?
Air-drying is the recommended method. Excessive heat can cause the latex to crack or lose its elasticity.
Is this safe to use indoors?
It must be used in a well-ventilated area to dissipate fumes during the evaporation of the water content.
Can I reuse the master object?
Yes, the latex is designed to be peeled off without causing damage to the master, provided the surface is not overly porous.
What casting materials work with this latex?
It is well-suited for casting plaster, candle wax, and similar low-temperature casting compounds.
How do I clean my brushes?
Clean brushes immediately with warm, soapy water. Once the latex cures on the bristles, it becomes very difficult to remove.
Troubleshooting
Latex is clumping or skinning in the bottle
Ensure the lid is screwed on tightly after every use and store in a cool environment.
Mould is tearing upon removal
Apply more layers in future projects to increase the overall wall thickness and strength of the mould.
Bubbles are appearing on the master surface
Use a soft brush to gently stipple the first layer of latex onto the surface to force out air pockets.

Setup, Compatibility & Care
To begin, ensure your master object is clean and dry. If the surface is porous, apply a thin release agent or sealant first to prevent the latex from bonding permanently. When working, use brushes that you do not mind discarding, or clean them immediately with warm soapy water before the latex dries. Store the product in its original container, ensuring the lid is airtight to prevent the latex from skinning over inside the bottle. Keep the container in a cool, dark place, away from direct sunlight or freezing temperatures to maintain its shelf life.
