How to Coat and Smooth an Old Textured Wall?

Want to give your wall a new lease on life by covering up an old textured finish? It’s easy (well, almost)—you just need to achieve a smooth surface. One of the best techniques is applying a coating with a roller.

Here’s how to do it, step by step, as explained by Beissier’s expert, Jeremy.

Why Smooth an Old Textured Wall?

Once popular, textured walls can now feel outdated. But how can you get rid of them and create a smooth finish? The solution: coating application.

Step 1: Preparing the Surface for Coating

Before applying a roller-applied coating on an old textured wall, you must prepare the surface properly.

Key Preparation Steps:

Sand the entire wall to even out irregularities.

Expert tip from Jeremy: Use 40-grit sandpaper—this will help you use less coating while still achieving a smooth, refined finish.

Remove dust and wipe down the surface with a damp cloth to ensure optimal adhesion.
Apply a clear primer to stabilize the surface before coating.

Allow 24 hours of drying time before proceeding to the next step.

Step 2: Applying the Two-in-One Prestonett L Coating

To coat an old textured wall using a roller, Beissier experts recommend Prestonett L, a two-in-one filling and finishing coating.

Why Choose Prestonett L?

Provides thick coverage (up to 5 mm).

Ideal for interior walls and adheres to various surfaces, including:

Concrete
Ceramic tiles
Cement
Plaster
Wood
Glass mosaic
Old paint
And, of course, textured walls

Application Process:

Step 1: Apply Prestonett L with a roller for even distribution.

Step 2: Smooth the surface using a perfect-smooth blade.

Important:

If working alone, apply the coating in 1-meter-wide sections, smoothing as you go before moving to the next area.
Let the first coat dry for 24 hours before applying the second coat.
Follow the same two-step process (application + smoothing) for the second coat.
