LATONIT stuff-dyed fibre cement boards represent a board made from cellulose fibers, mineral filler, cement, and dye (pigment) by premixing of the components before molding. This produces homogeneous composition of the mass with the pigment uniformly distributed over the entire volume.
LATONIT stuff-dyed boards demonstrate quality and lasting color both inside and outside. Fibre cement boards uniformly dyed over the entire thickness ensure color stability even in the case of minor surface damages.

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.
