Painting : Techniques for Sanding

Painting : Techniques for Sanding 

In addition to sheeting up carpets and furniture and masking off fittings, it is a good idea to keep the door of the room closed to prevent dust spreading to adjacent rooms. It is helpful to place a folded dust-sheet at the bottom of the door and one spread out at the other side of the door. This will help to prevent dust and debris being trodden beyond the room.

Economy tip: Always tear full sheets of abrasive in half, then fold into three, giving you three fresh unused sides.

Decorator's Dodge Slap a used and clogged piece of abrasive hard on to a hard surface;
this tends to unclog and prolong its use. Use worn sheets as a final sanding abrasive (except for delicate finishing).

Wear a cap or hat, and be sure to wear a dust mask to avoid breathing in harmful particles. It is a good idea to open windows to increase ventilation

Large areas Sand in a series of circles and wrap the abrasive around a block of wood.


New wood Always sand at a very slight angle across the grain.
Because new wood often has sharp corners and edges, sand these slightly to make them safer and less likely to split if they get a knock.

Safety note: Wear a thick glove when sanding - it is easy to get splinters and spells in your hands when sanding woodwork.

Intricate areas (such as stair spindles) Make a small roll of abrasive, which will make it easier to get into the contours.

Sand with the grain Always sand in the direction of the length of the woodwork, not across the length. Use a fine- to medium- grade abrasive, not coarse, which will tend to cut into the wood or the paint too much.

Sanding between coats of paint
Sometimes called 'de-nibbing', this is best done very lightly with a fine-grade abrasive to remove any small particles in the dry paint, without cutting into the surface. Some people prefer to use a fine grade wet-and-dry abrasive with water, to 'flat-down' between coats (thorough rinsing is very necessary with this method).

Sanding down surface imperfections
To avoid stripping off paint in an area which has just a few imperfections such as old paint runs, it is possible to 'take down’ these areas using course abrasive and a sanding block, then finishing with a medium and fine abrasive. If there are a lot of imperfections, it is better to strip off the paint completely and start again.

After sanding
It is essential to remove the surface dust, first with a dust brush, then with a clean lint-free cloth dampened with white spirits. Or use a propriety ‘tacky rag' (or tack cloth).
