The plasterboard "Top" is a plate with round edges, 13 mm thick 1.25 m x 0.90 m. Its dimensions facilitate the transport and the implementation while offering technical and aesthetic performances of quality. Its rounded edges allow the use of the paperless seam technique thanks to a specific coating (Uniflott coating) for an easier finish with no extra thickness. This plate is available in standard universal version and in water repellent version for wet rooms.

Installation in partition on metal frame
1. Create a standard NF metal frame, consisting of 48/35 studs, with 45 cm spacing, and positioned between 48 mm rails. Screw the plates onto the frame.
2. Start by screwing an entire plate to one side of the wall and, on the other hand, start with a half plate, with the cut-off edge positioned against the floor or ceiling.
3. Make sure that on each side the siding is set off for better mechanical strength (60 joules).
Ceiling installation on metal frame
1. The plate can be fixed on a skeleton ceiling by laying perpendicular to the framework. The spacing should be about 40/45 cm depending on the configuration of the room, so that the four edges fall in support on a fur.
2. Screw the plate directly onto the metal furring, taking care to put the four edges in contact with the metal supporting framework.
The rounded or beveled edges of this plate make it possible to use the technique of joints without paper band by applying the special coating (Knauf Uniflott).
1. In a trough containing cold, clean water, pour the plaster down to the surface (max 2.5 kg in about 1.2 l of water).
2. Let the plaster rest for 2 to 3 minutes and mix it without adding with a coating knife to obtain a creamy paste.
3. Apply the coating. You can do this using a plaster knife or a large spatula. Work in small steps, between the joints, perpendicular to the plates and this over the entire height. Remember to close the screw heads.
4. Then scrape from bottom to top to spread the plaster. After 30 to 40 minutes, before final drying, remove excess coating.
5. Make a second application with a wider coating knife to obtain a smooth surface without overflowing the flat parts of the plates.
6. After complete drying, sand lightly for a perfect finish (especially if you have to paint the plate).
