Achieving a smooth, high-gloss finish on epoxy resin relies as much on the technique as it does on the products you use. One essential but sometimes overlooked step is testing how much pressure to apply while polishing by hand.
Why Pressure Makes a Difference
Applying the correct amount of pressure during hand-polishing is crucial for a flawless resin surface. Too little pressure and the polish will not be worked in properly, leading to dull, cloudy patches. Excessive force, on the other hand, can cause uneven gloss or even surface damage. Striking the right balance ensures a high-gloss, mark-free result and prevents rework.
How to Test and Adjust Your Pressure
- Start gently: Begin with light, even strokes using a dedicated hand pad or sanding pad. Check the surface after a few passes.
- Step up gradually: If the polish remains cloudy, slightly increase the pressure and continue in a circular motion. Listen for subtle resistance and monitor gloss improvement.
- Use the right tools: A proper polishing pad or foam sanding block distributes pressure more effectively than a cloth. The Epoxy Polish system is designed for this kind of application, helping you control pressure while maximising shine.
When Pressure Testing Matters Most
If you’re new to resin finishing or working on a delicate project, testing your pressure ensures you won’t overwork or miss parts of the surface. This is especially important when using high-grit sanding pads or polishing systems after the final sanding stage.
