LATONIT fibre cement boards are intended to be used in ventilated cladding of multistoried buildings, both newly built and reconstructed, as well as for interior cladding of buildings and constructions. The proposed material allows all-the-year-round dry installation, economical and reliable restoration of any façade, and reduces building heat losses.
Acrylic-dispersion-based painting compounds specifically developed for fibre cement boards are used to paint LATONIT boards. After being applied and polymerized, they form weatherproof, vapor-permeable protective and decorative coating having high wear and temperature-drop resistance. The painting color may be selected from RAL, NSC, RAL Design catalogs or customer’s samples.
* Note: Boards of different sizes may be manufactured upon coordination with the customer

LATONIT fiber cement boards are painted on modern lines in strict accordance with the board preparation and painting process.
After the boards are cut per the customer’s dimensions, their face is ground and saturated with a special mixture to strengthen the fiber cement board’s top layer. Then, the sides are treated and painted. After that, the prepared fiber cement boards arrive at the painting line.
The first step of painting is applying a primer compound on the board’s face. Then, three-coat painting of the board’s face and two-coat painting of board’s rear surface are performed simultaneously. The final step of the painting is UV varnish application. This step increases the strength of the paint-and-varnish coating, extends the painted surface’s life, and improves the surface’s resistance to chemical exposures.
All the paint-and-varnish coating application steps are done under constant control by the quality control department and the laboratory, which ensures high quality of the LATONIT painted fiber cement products.
