Sanding (page 2) - Wet and dry paper

Back to page 1

Painted surfaces are more quickly rubbed down using a wet technique. The cutting power is governed by the material used to manufacture the sandpaper.

Wrap the wet or dry paper around a rubber block, dip in a bucket of water and sand in the normal way. While working, regularly rinse the paper and always keep it wet.

The water acts like a lubricant, enabling the paper to travel over the surface easily. It also holds the paper firmly in contact with the surface.

With a little practice, this type of sanding produces high quality results.

On broad areas, a slight overlapping circular motion can be used.

Narrower areas and mouldings should be sanded lengthways.

Recesses in mouldings can be sanded using a small folded piece of sandpaper, which can be pushed up and down along the groove. Alternatively, for extra control, fold the paper over the end of a scraper.

The surface should be rinsed afterwards using clean water and a sponge. Allow to dry before repainting.

Cut standard size paper widthways in half for cork blocks, and into quarters for rubber blocks.

Always wear a mask to protect against dust. Check that the mask you buy gives protection against the type of dust being produced.
