Product Information
Full details
West Design Moulding Latex is a high-performance liquid rubber emulsion designed for hobbyists, model-makers, and special effects artists looking to capture fine detail from master patterns. It offers exceptional surface reproduction on materials like plaster, clay, and wood, allowing users to create custom, peelable moulds with ease. While it provides excellent definition, users should be aware that the ammonia-based formula requires application in well-ventilated spaces and may require the addition of a thickener for use on non-porous surfaces.

FAQs
Is West Design Moulding Latex safe to use indoors?
It is ammonia-based, so you must use it in a well-ventilated area to ensure proper air exchange and comfort.
Can I use this on a non-porous master?
Yes, but you will likely need to add a thickening agent to prevent the latex from running off the surface.
How long does it take to dry?
Drying time depends on the thickness of the application and the ambient humidity. Multiple thin layers will dry faster than one thick application.
Can I paint the finished mould?
Yes, the cured rubber surface can be painted to achieve a professional or custom look for your projects.
Is this product water-based?
Yes, it is a water and ammonia-based emulsion.
Troubleshooting
Latex is running off the master pattern
The surface may be non-porous; add a thickening agent to the latex to increase viscosity and improve adhesion.
Mould is tearing during removal
Ensure that enough layers were applied to provide sufficient thickness and strength to the mould before peeling.
Surface finish appears uneven
Ensure the first layer is applied thinly and evenly to capture details, and allow complete drying time between subsequent coats.
Pros and Cons

- Air-drying process is dependent on thickness and environmental conditions
Setup, Compatibility & Care
To use this moulding latex, ensure your workspace is well-ventilated due to the ammonia content. Begin by coating your master pattern—if the master is very porous, consider a light release agent for easier removal. Apply the latex using a soft brush or by dipping, depending on the size of your project. If the consistency is too thin for your needs, add a compatible thickening agent in small increments until the desired viscosity is reached. After use, ensure the container lid is sealed tightly to prevent premature skinning or drying of the remaining latex. Store in a cool, dry place away from direct sunlight to maintain the shelf life of the emulsion.
