120 Grit on Delivery
Before leaving the KPJ factory all hardwood products are finished with a 120 Grit Sandpaper. This is done to ensure the least amount of prepping before applying a treatment , while maximising absorption and minimising the amount of sanding required after the treatment has been applied. Oiling and painting require a slightly different process to completion. Refer to Grit Guide
Sanding Tips
- Sand with the direction of the grain NOT across the grain
- An orbital sander will ensure the best finish
- Sand the whole surface area evenly. This is especially critical on larger surfaces because an unevenly sanded surface will result in colour differences across the surface
- Avoid handling the surface after sanding is complete
- All dust should be wiped from surfaces before treatment is applied. A damp cloth may be used but it is of critical importance to allow the surface to dry properly before treatment is applied.
- Make sure there is no glue on the surface being treated
- No liquid must be spilt, especially water after sanding is complete
