Wasa straight mirror cornice in two parts – the upper mirror is made of plasterboard and the lower elegant profile is made of model plaster. Product dimensions and technical specifications are made according to the customer’s wishes
Features. The product has similar properties as plasterboard, except for the places that are machined and glued, the lower part of the cornice is made of model plaster
Usage. The product is intended for use in rooms with a relative humidity of no more than 70%. The maximum installation temperature is 50°C
Installation
⇒ 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 using a wooden or metal frame. If the shape of the product and the profile of the nearby surface allow it, the product can be properly attached to it
⇒ It is recommended to use either wooden material or a metal frame to connect the products together, which connects both halves of the product together in such a way that cracks do not form at the joints after finishing
Fixing. In sparse areas of the product (e.g. glued surfaces and gaps associated with sawing and milling), it is recommended to use adhesive foam or adhesive sealant instead of screw connections. The requirements for screwing the product are described in the plasterboard installation instructions
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
⇒ NB! Sawing must be done carefully – a blunt saw, large saw teeth and placing the product on a base can cause the product to break in an unwanted place
Finishing. Similar to finishing drywall
Filling joints. Similar to filling plasterboard joints, if necessary, chamfers can be cut into the edges of the product to accommodate a sufficient amount of sealant or joint filler. It is recommended to use either mortar made of gypsum powder or fine filler for treating the surfaces of the lower part – cast gypsum cornice. Gypsum mortar hardens quickly and is easy to sand
Storage. Products should be stored on a smooth surface, preferably on a pallet. Protect products from moisture
Transportation on the construction site
⇒ The product must be carried correctly supported and carefully – high tensile pressure can cause the glued surface to come loose.
⇒ If there is a risk that the product will be damaged during transport, additional covers or additional fastenings must be used
⇒ It is recommended to transport long or heavy parts with two people and with two hands
⇒ The internal support blocks and fastening tape of the parts are removed (if necessary) immediately before installation
Dimensions. The cross-section of the mirrored cornice shown in the pictures is 0.3 x 0.3 m. The length of the cornice is up to 3 m. The transportability of the product and its parts to the installation site must be taken into account

⇒ CNC-cut ribs to maintain the shape of the arch during gluing and transportation
⇒ Tape to fix the shape of the product during gluing and transport
⇒ For the transportation of straight model plaster cornices, if desired, plasterboard gutters (U-profile) can be made, which are lined with a soft base film
⇒ The production process from pulling the cornice part from cast plaster to the end of drying is 1-3 weeks depending on the intensity of drying
