Plasters and mortars

The calcium carbonate is a key filler for improving the performance and aesthetics of plasters, renders and mortars, while optimizing production costs.

Whether it’s for fillers, joint finishes, adhesive mortars, facade coatings or plasters, the choice of calcium carbonate is crucial and must be studied according to the desired characteristics.

The geographical coverage of our production sites reduces supply distances.

Benefits

Whiteness and surface appearance

Calcium carbonate is one of the whitest fillers, giving plasters high levels of whiteness. The surface appearance of the plaster is also controlled by the grain size of the calcium carbonate used.

Shrinkage and water retention control

The use of calcium carbonates with a suitable particle size distribution helps to control water retention and minimize plaster shrinkage during drying, which is particularly important for filling plasters.

Garnishing

The plaster's filling effect is achieved by the appropriate choice of calcium carbonate, which increases the plaster's ability to fill irregularities and ensures even application.

Easy to apply

The ease with which plasters can be applied also largely depends on the choice of calcium carbonate. In particular, it controls slipperiness, a very important feature for finishing plasters.

Texture control

Calcium carbonate can be used to modulate the structure of finished products, whether smooth or granular. The use of small grains of calcium carbonate thus makes it possible to obtain the desired finish in single-coat plasters.

Cost reduction

Calcium carbonate is the filler of choice for optimizing the cost of plasters of all types.

The use of calcium carbonates with an appropriate particle size distribution helps to control water retention and minimize plaster shrinkage during drying, which is essential for filling plasters.

Filler coatings

Filler coatings

Calcium carbonate adjusts the viscosity of plasters, making filling easier and preventing drips. Its low hardness (3 on the Mohs scale) also makes the plaster easier to sand.

Finishing / smoothing plasters

Finishing / smoothing plasters

The choice of calcium carbonate is the key to the right texture and optimum glide, making it easier to smooth the surface and achieve the desired finish.

Joint fillers

Joint fillers

The choice of calcium carbonate optimizes adhesion and mechanical strength. Controlled particle size distribution ensures a clean, flawless finish on the joint tape.

Adhesive mortars

Adhesive mortars

As adhesive mortars are used to fix materials, the calcium carbonate introduced into the formulas must enable optimum adhesion and cohesion properties to be maintained at lower cost.

Single-coat rendering, rendering, ITE systems

The diversity of grain sizes offered by Provençale SA ensures continuity between small particles and small grains of calcium carbonate. Small grains influence the texture, appearance, durability and ease of application of the plaster.
