Why is treating cracks important?

Cracks can occur for many reasons, from structural movement, temperature variations, to the natural expansion of materials.

Ignoring these cracks can lead to water infiltration, mold growth, and faster deterioration of surfaces.

By properly treating cracks, you extend the life of your walls and ceilings while improving the aesthetics of your interior spaces.

To ensure a quality repair, it is recommended to call on an experienced painter, particularly in the Saint-Tropez and Draguignan region.

The different types of cracks and their treatment

Not all cracks are treated the same way. It is important to properly identify the type of crack before proceeding with the repair, as each requires a specific approach to ensure a lasting repair.

1. Surface cracks

Surface cracks are small cracks that often appear on the surface of walls or ceilings, without affecting the structure of the building.

They can be caused by drying paint or coating, or by slight temperature variations.

To treat them, a simple filling with a smoothing compound is sufficient.

Application example:

In a house in Ramatuelle, the treatment of superficial cracks on plaster walls makes it possible to obtain a smooth surface before painting, guaranteeing an impeccable and uniform finish.

2. Medium cracks

Medium cracks are usually between 2 and 5 mm wide.

They are often due to movements of the structure, but do not compromise the stability of the building.

To fill them, it is recommended to use a filler or an acrylic putty for better flexibility.

Application example:

For an apartment in Sainte-Maxime, filling medium cracks with an acrylic sealant allows the movements of the structure to be accommodated without the crack reappearing.

3. Deep or structural cracks

Deep or structural cracks are of most concern, as they indicate a problem with the building's structure.

They often appear in the corners of walls or at foundation level.

Their width can exceed 5 mm, and they can pass through several layers of materials.

For these cracks, a professional diagnosis is recommended, and treatment may require specific products such as sealing resins or reinforced strips.

Application example:

In an old house in Grimaud, treating structural cracks with a sealing resin helps to stabilize the wall before applying a finishing coat and painting.

The steps of crack treatment

Crack treatment takes place in several stages to ensure a long-lasting and aesthetic result.

Here are the main steps to follow for an effective repair.

1. Diagnosis and preparation

Preparing a wall crack with a scraper in a sunny room, a crucial step for an effective repair.

Before starting repairs, it is essential to analyze the nature of the crack in order to choose the appropriate treatment method.

Then the crack should be opened and cleaned with a scraper or cutter to remove loose parts and dust.

This ensures better adhesion of the filler products.

Application example:

In a villa in Les Issambres, opening and cleaning the cracks allows the walls to be prepared for effective filling before the complete renovation of the room.

2. Filling with a coating

Once the crack is clean, it is time to fill it with a suitable filler.

For small cracks, a smoothing compound is sufficient, while for larger cracks, a filler is recommended.

The application should be carried out in several thin layers to avoid hollows and ensure a uniform surface.

Application example:

In Draguignan, filling cracks in the ceilings of an old apartment allows the surface to be prepared before applying white paint for a bright finish.

3. Sanding and finishing

After the filler has dried completely, light sanding is necessary to smooth the surface and remove traces of the repair.

This results in a surface ready for painting or wallpapering.

Application example:

In Sainte-Maxime, sanding after filling cracks in Placoplâtre walls ensures a smooth finish before installing decorative wallpaper.

Recommended products for crack treatment

To ensure the durability of repairs, it is important to choose the right products.

Here are some types of fillers commonly used for crack treatment.

1. Filler

Spackle is a paste-like product used to fill medium to deep cracks.

It is often enriched with fibers for better resistance.

Application example:

To fill cracks in a house in Grimaud, the filler ensures a solid repair before applying paint.

2. Mastic acrylique

Craftsman carefully applying acrylic putty to wall corners, a key step in supporting structural movements.

Acrylic filler is recommended for light to medium cracks because it remains flexible when dry.

It is ideal for walls that may still move slightly with temperature variations.

Application example:

In Roquebrune-sur-Argens, the application of acrylic putty in the cracks of the corners of the walls allows the movements of the building to be followed while maintaining a smooth surface.

3. Sealing resin

Sealing resins are liquid products that reinforce deep cracks and stabilize walls before filling.

They are particularly recommended for structural cracks.

Application example:

In a house in Ramatuelle, the use of sealing resin to stabilize structural cracks before applying a…wall, ensures solidity before applying a smoothing coating for finishing.
