Sandpaper Basics

Sandpaper can be used with power tools and for sanding by hand. A power sander removes material quickly and efficiently. It’s a good choice for getting rid of surface blemishes and for shaping and leveling wood. Power-sanding is also an effective way to prep surfaces for painting.

Sandpaper Types

One way to determine which sandpaper will work best for a particular job is to know the abrasive materials and their properties.

Sandpaper Grit Numbers

The grit number of a sanding product indicates the size of the abrasive particles. The lower the number, the larger the abrasive particles; they remove more material but create more-noticeable scratches. A higher number indicates smaller particles, which don’t remove as much material but leave a finer, more polished appearance.

Other Abrasives

In addition to sandpaper, there are other abrasives, available in a range from coarse to fine:

1 – Get the Correct Sanding Equipment

Before embarking on your sanding task, it is crucial to know the tools and types of sandpapers that should be used. When it comes to the sandpapers, you can use one of these: garnet paper (usually tannish-brown), the gray aluminum oxide paper and the black silicon carbide sandpaper.

2 – Do not Sand the Gouges, Fill them Instead

If you want to know how to sand drywall like a pro and get great results, you are advised to touch up large ridges and grooves with an additional joint compound coat instead of attempting to sand them out. This comes in handy at joint edges where using excess sanding will destroy the paper face used on the drywall.

3 – Use a Handheld Light to Identify Problem Areas

It is important to know how to sand drywall skillfully using handheld light. Simply go back over your ceiling and walls with a sander and a light. Use a pencil to circle pits and dings or any other little mistakes that might be in the sanded-through area. After this, rectify the mistakes by touching them up using joint compound.

4 – Sand the Walls Again After Priming

Most beginners skip this crucial step. You are required to prime your wall surface and sand it lightly immediately the primer dries; this removes lumps and paper fuzz. You can take care of other imperfections on the wall during this step.

5 – Deal With Those Pesky Corners

You do not know how to sand drywall like a professional if you do not understand the importance of sanding sponges when you are working on the corners. Most people use large hand sanders instead of the sponge during this stage which is not recommendable.

6 – Remember to Avoid Over-Sanding

Worry less if you have over-sanded; simply touch the spot up with joint compound, wait for it to dry and re-sand. Use light pressure when doing all this. Avoid using a straight line when you are sanding the same spot if you do not want depressions and grooves that will become visible after painting.

7 – Proceed to the Final Painting Preparations

It is wrong to vacuum or sweep the surfaces to remove the dust when you are preparing to paint it. Minimal ceiling and wall cleaning are recommended by experts. Surprisingly, you are advised to leave an even layer of dust on your drywall surface.
