Installation and fastening

⇒ The corresponding technical solutions have been provided by the construction project developer for installation on construction sites

⇒ It is recommended to install the product on a stone, frame, wood or plaster surface with a sealant that adheres well to plaster. If the shape of the product and the profile of the nearby surface allow it, the product can be properly attached to it

⇒ In addition to the sealant, heavy parts must be additionally fixed with fixing screws. Screw holes and recesses for the screw heads must be pre-drilled, later the screws are covered with joint filling material

⇒ It is recommended to use a sealant to connect the products together, with which both halves of the product are connected and the surfaces are cleaned in such a way that cracks do not form over the joints after finishing

Cutting. In case there is a need to cut the product,

⇒ Use a saw with small teeth, such as a miter saw

⇒ To obtain the correct cutting angle, it is recommended to use an angle saw

⇒ When cutting the entire product, mark the cutting line (straight or cutting angle) with a laser

Filling the joints. For the treatment of gypsum surfaces, it is recommended to use either mortar made of gypsum powder or fine putty. Gypsum mortar hardens quickly and is easy to sand
