What Are the Tips for Sanding Walls with Abrasive Paper?

In wall renovation and decoration, abrasive paper grinding is a common step in making an uneven wall smooth and removing wall stains. First, use coarse abrasive paper to grind the wall horizontally until the wall shows a new white color. Then, use fine abrasive paper vertically to remove the marks left by the coarse abrasive paper. Finally, wipe away the debris and dust with a dry towel. Choosing the right abrasive paper and grinding time is important depending on the degree of smoothness needed.


Method of abrasive paper grinding on the wall


In home decoration, we often encounter wall stains or unevenness. We can use abrasive paper to grind the wall and make it smooth. The method for waterproof abrasive paper grinding the wall is:


  • Prepare the necessary tools: coarse abrasive paper, fine abrasive paper, and a towel.

  • Use the coarse abrasive paper to rub the wall horizontally until the wall shows a new white color.

  • Then use fine abrasive paper to achieve a smooth surface and remove the marks left by the coarse abrasive paper.

  • Finally, use a dry towel to wipe away the debris and dust, making the wall smooth and clean.


Common techniques in abrasive paper wall grinding


Using abrasive paper to make a wall smooth can be improved with some techniques:


Choose the right abrasive paper


If the abrasive paper is too coarse, it may cause scratches, and if it is too fine, it cannot be ground smoothly. Choose abrasive paper with the right grit size based on the wall putty.


Choose the right grinding time


If you want to polish the wall, choose the right time to grind. The best time to work on the wall is within 3 days after applying the putty. Before the wall dries completely, the surface is weak and easily ground.


Adjust the grinding to the degree of smoothness needed


If the wall is smooth and there is no resistance during grinding, continue grinding. If it is challenging to achieve smoothness, choose coarser abrasive paper to grind and remove scratches with finer abrasive paper later.


Precautions for abrasive paper grinding on the wall


  • Do not wet abrasive paper when grinding the wall. Always use dry abrasive paper.

  • Use coarse and fine abrasive paper alternately.

  • Pay attention to the direction of the abrasive paper grinding. Horizontal grinding removes dirt while vertical grinding removes scratches.
