Proper surface preparation makes a world of difference when using release wax for resin projects. Cleaning beforehand is recommended for the best results and to avoid common casting issues.
Why Cleaning is Essential Before Waxing
Any dust, oil, grease, or residual adhesives left on a mould or surface can prevent wax from bonding evenly. This causes patchy coverage, which might let resin seep through and stick where you want a clean release. Using a dedicated degreaser helps remove stubborn residues so the wax can form a consistent, protective film.
For a thorough clean, consider products like the Strong Technical Degreaser, designed specifically to tackle greases, silicone, markers, and more without damaging most surfaces.
How to Prepare Your Surface for Wax Application
- Wipe the surface free from loose dust and debris.
- Apply a degreasing agent and wipe thoroughly to remove oils, adhesives, and other contaminants.
- Let the surface dry completely before waxing.
- Proceed with a suitable release wax, such as the Global A2 Release Wax, brushing or spraying evenly on wood, metal, plastic, or cardboard.
When Cleanliness Matters Most
Clean surfaces make a noticeable difference for intricate moulds, repeated castings, or when switching between mould release systems. Skipping this step can lead to flawed castings or reduce the mould’s lifespan.
