Proper surface preparation is key to achieving a flawless spray finish on resin. Degreasing ensures resin surfaces are free from contaminants, allowing sprays and lacquers to bond effectively for optimal results.
Why is degreasing important for resin surfaces?
Resin projects tend to pick up oils, fingerprints, and dust during handling or curing. Any of these residues can block adhesion, leading to uneven finishes or peeling. By using a suitable degreaser, you remove invisible films that might interfere with lacquers or protective sprays, ensuring a smooth, professional look.


How to degrease resin safely and effectively
A natural, solvent-free cleaner like the Strong Technical Degreaser for Resin Projects is ideal. Simply apply the product to a lint-free cloth and wipe your resin surface thoroughly. This formula is gentle on both skin and your workpiece, making it suitable for everyday use without harsh odours or irritation. Always allow the surface to dry fully before applying any spray or lacquer.
When this step matters most
- High-gloss finishes: Any residue will be highlighted under glossy lacquers.
- Layering sprays: Reliable adhesion between coats depends on a clean surface.
- Handling after curing: Even a quick touch introduces oils that can compromise the finish.
