Chestnut Products CSS500 Cellulose Sanding Sealer – 500ml

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. This not only makes it more 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.
Cellulose Sanding Sealer is very quick drying, usually touch dry in 30 seconds and ready to be sanded within five minutes, making it ideal for a quick, easy yet professional base for your finishing.

Sanding Sealers

A Sanding Sealer does many things.
It seals the open pores of the timber, meaning you use less of the top coat. And that’s not only good for your pocket; using less means a thinner film, which is less likely to get damaged.
It also smooths out minor irregularities in the surface, to give a better foundation for finishing.
And it binds together the loose, fibrous material that you can’t see, but is lurking on the surface to make your finish weaker.
Once it’s done all that, usually in the time it takes you to put the lid on the can (remembering to wipe the neck of it so it opens easily next time), a sanding agent in the sealer acts as a lubricant to make sanding it back as easy as possible!
Clever stuff eh?

Sanding Sealers come in several forms, quick drying cellulose for turning and small areas, slower drying shellacs and acrylics for larger areas. Or whichever way round is your preference. And there are easy-to-apply aerosols too.
