Questions
- Is the P-TEC 8400 food safe?
YES! The P-TEC 8400 is a Polyurethane paste 100% Solid and 0% VOC. Therefore it can be use safely on charcuterie board or Serving trays.
- Will the P-TEC take stains and oils?
Once fully cured the P-TEC 8400 can be light sanded and will take stains, oils and pigments that are ZERO VOC. Make sure to test on a small piece to validate the compatibility with your finishing products.
- How high should the PTE-8400 be sanded?
We recommend 150-250 for the best results and not exceeding 400 grit for the only reason that if the P-TEC 8400 is sanded too high, the surface will become too smooth for the finishing products to link.
