Textured walls come in a variety of texture levels. Let’s go over how to smooth textured plaster walls.

Steps To Get Modern Smooth Wall Texture

Step 1: Clear walls and your space

Remove all accessories aroundView in gallery

Before you can begin smoothing out your textured walls, you need to remove all accessories from your space.

This includes any removable wall items such as towel rods. This will allow for a thorough wall-smoothing while omitting the risk of damaging your hardware.

Step 2: Cover electrical outlets with tape

After all removable items have been removed from your space, cover all electrical outlets with painter’s tape. Also, cover all drains and vents with tape, plastic, or towels. 

The dust this project will create will permeate every nook and cranny, so be thorough in your cranny-coverage. Also, open a window to keep the space well-ventilated.

Step 3: Begin sandpapering your walls 

Put on your dust maskView in gallery

Put on your dust mask. Begin with a coarse sandpaper, such as 80-grit. Be prepared to use lots of sandpaper. 

Depending on the density and depth of your wall texture, each piece of sandpaper will last for 2-6 square feet. Even in a small bathroom, that’s a lot of sandpaper.

Start sanding your walls. 

This first pass isn’t going to get everything perfectly smooth, but you’ll want to create a relative flatness between the wall “base” and the peaks of your texture.

Here’s a demonstration of where the texture peaks were before the first sanding pass. 

The brown color is the top paint, the greenish color is the plaster itself, and the white color is where the sandpaper dug into the drywall. 

Try to avoid getting into the drywall as much as possible, although it will probably happen a little bit.

Pressing harder on your electric sanderView in gallery

Note that pressing harder on your electric sander isn’t always the most effective strategy; it can inhibit the rotation of the sandpaper itself and actually take away from the sander’s effectiveness. 

Find a balance between providing enough pressure on your sander so there’s definite friction between the sandpaper and the texture, and easing off enough so the sandpaper rotates freely. 

The sanding will create dust everywhere.

Seriously, dust coats everything. This was after about 12 square feet of sanding the first pass.

Step 4: Compare smooth vs. textured walls

Flatter walls agains a source of lightView in gallery

It’s a good idea, when possible, to step back and view your flatter walls against a source of light; the various sheens and reflections will provide a clue as to what is done and what needs more sanding.

 A step-back perspective is something I recommend every time you switch out your sandpaper.

Step 5: Touch up any areas that need more sanding

Notice areas on wallView in gallery

If you notice a few imperfect smooth wall texture areas that could use touching up during your step-back review, touch them up with fresh sandpaper before moving on.

Also, although you will be able to see much of where you need to sand more, you can’t always trust your eyes. 

Use your non-sanding hand to feel areas of the wall for flatness. 

Use your eyes and hands to guide your sanding progression.

Step 6: Vacuum as you go

Be sure to vacuum as you go. Dust builds up quickly.

Step 7: Wipe down walls

After you’ve gone over your walls with 80-grit sandpaper and are satisfied with the level of flatness, you’ll need to wipe off the coat of dust with damp paper towels or baby wipes.

Step 8: Sandpaper one more time

Sandpaper again. 

Mount a medium grit (120-grit) sandpaper onto your sander, and repeat the process around your walls. 

Swap out your 120 grit sandpaperView in gallery

Pro Tip: Remember to swap out your 120-grit sandpaper every few square feet, just like you did with your 80-grit sandpaper, to maximize effectiveness and flatness.

Step 9: Enjoy your smooth texture walls!
