Prepare the wall before painting

Preparing a clean wall for painting, with a painter in action in a modern room.

Wall preparation is a crucial step to ensure a smooth and durable finish.

If this step is neglected, even the best paint will not adhere properly or last over time.

Here are the steps to follow to properly prepare a wall before painting it.

1. Cleaning the wall

Cleaning is essential before applying paint. A clean wall allows the paint to adhere well to the surface.

It is recommended to dust and clean the wall with soapy water to remove grease and dust.

If there are any traces of mold or grease, use degreasing products to clean these areas.

Application example:

If you are painting a kitchen wall, it is important to remove any grease before applying the paint, as this could prevent good adhesion.

2. Repair cracks and imperfections

Before painting, it is important to fill cracks, holes and other imperfections in the wall.

Use a filler to fill these defects, then sand the surface once the filler is dry to obtain a perfectly smooth wall.

Application example:

If your wall has cracks or holes left by nails or dowels, it is essential to fill them with filler and sand the surface to obtain a smooth finish before painting.

3. Apply an undercoat

Applying an undercoat is essential to ensure good paint adhesion and better coverage.

This is especially important if you are painting a new wall, a plaster wall , or going from a dark color to a lighter color.

The undercoat makes it possible to standardize the surface and avoid traces of rework.

Application example:

To paint a wall with a bright color, applying a white undercoat will give a more vibrant final color and limit the number of coats needed.

Choosing the right tools for painting a wall

The tools used to paint a wall directly influence the quality of the final result.

Whether you are a professional painter or an individual, it is important to use rollers, brushes and other accessories adapted to the surface to be painted and the type of paint chosen.

1. The right rollers and brushes

To paint a wall , the roller is the main tool to use.

It allows you to cover large areas quickly.

However, it is essential to choose the right type of roller depending on the paint used (acrylic, glycerol) and the desired finish (matte, satin, glossy).

Brushes, on the other hand, are essential for finishing touches, especially in corners or around switches and electrical outlets.

Application example:

A short nap roller is recommended for satin or gloss paints on smooth walls, while a long nap roller is more suitable for rough surfaces such as rendered walls.

2. Bac à peinture et grille d’essorage

The paint tray allows you to measure the amount of paint on the roller, while the wringer grid removes excess paint to prevent drips and achieve a uniform application.

These accessories are essential for clean and professional work.

3. Masking tape and protective tarps

Before you start painting, it is important to protect any surfaces that are not to be painted , such as baseboards, window frames or floors.

Use masking tape to mark off areas to be painted and drop cloths to protect your furniture and floor.

Application example:

In a room with molding or woodwork, it is essential to apply masking tape to prevent paint from bleeding onto these delicate surfaces.

The steps to properly paint a wall

A painter carefully mixing paint in a bucket using a wooden stick.

Now that your wall is prepared and you have chosen your tools, it is time to move on to applying the paint.

Here are the steps to follow to ensure a consistent, streak-free result.

1. Mix the paint

Before applying the paint , it is important to mix it well to homogenize the pigments.

This helps to avoid differences in shade between the different layers.

Use a paint mixer or wooden stick to mix the pot well before each use.

2. Start with the corners and edges

Always start by painting the corners , corners and edges (around windows, doors, electrical outlets) using a brush.

This allows you to clearly define the area to be painted and obtain a clean result.

3. Paint using crossed stripes

A painter applying paint in vertical and horizontal stripes on a large wall with a roller.

To achieve an even result, apply the paint in crossed stripes.

Roll vertically, then horizontally.

This helps distribute the paint evenly and avoids roller marks.

Application example:

Apply the paint in an “M” or “W” shape on the wall, then smooth the paint by rolling from top to bottom without too much pressure.

4. Apply several coats if necessary

In most cases, two coats of paint are necessary to achieve good coverage.

Allow the first coat to dry according to the manufacturer's instructions before applying the second.

If you are going from a dark color to a light color, a third coat may be necessary.
