Good finishing requires a good foundation, and Cellulose Sanding Sealer is probably the best way of providing one. Compatible with everything in the Chestnut Products range that benefits from the use of a sanding sealer (which is pretty much everything apart from oil finishes!) it is superbly universal.

The purpose of a sanding sealer is manifold.

  • It seals the open pores of the timber prior to the application of the next coat, meaning that more of it stays on the surface and less of the finish is needed. Not only does this make it economical, when finishing the thinner the applied coat the less likely it is to get damaged, so a sanding sealer will help the top coats be more resilient.
  • Sanding Sealers also bind the loose fibres of the timber together giving a more solid foundation for the next coat, which helps make sure the final finish is able to adhere properly and thus be more durable.
  • They also include a sanding agent which acts as a lubricant to make the sanding process easier – the sanding agent also stands slightly proud of the surface of the sealer and it is this that is denibbed – the sealer itself should still be intact after sanding.
