How to Sand Drywall like a Pro

Follow these steps and you’ll be ensured to achieve an excellent result.

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. Aluminum oxide or garnet sandpapers are ideal for drywalls because:

  • They do not clog
  • Aluminum oxide last longer as it wears out slowly
  • The aluminum oxide paper is thicker

Although this can be done by hand, you’ll be much better off if you use an electric sander. They save you a world of time, effort and allow you to achieve better results too – check out the best drywall sanders and get yourself the right one for the task.

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. It is easy and quick to fill the depression with a thin coat.

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. You need to wait for the spots to dry and resand them.

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. This is like asking for trouble; you will have a hard time getting a crisp corner when you use a hand sander.

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. The dust binds with your paint and acts as fillers that mask pinholes, chafed surface paper, and scratches.

Common Drywall Mistakes to Avoid

It is essential to know these mistakes as you are likely to make them as a beginner.

  • Applying drywall on your walls before your ceiling
  • Exposing the wrong side of the drywall sheets when applying them
  • Over-sanding the drywall paper
  • Driving the drywall screws too far –This will puncture the paper
  • Misaligning the electrical boxes’ holes
  • Failing to make the taped joints solid and strong – This will make the drywall seams to crack

Follow these simple pro-tested tips to get beautiful, paint-worthy surfaces. Dust may be your opponent at the beginning of the drywall sanding project; ironically, it comes in handy during the final steps. Therefore, it is important to dust the surfaces appropriately but not completely.
