Interior DIY plasterboard wall trimming is one of the so-called “dry way” finishing. This option can significantly reduce the time of repair, skip the process of the walls alignment, eliminate the use of concrete and cement mixtures, leading to a significant economy.
Interior wall decoration with plasterboard can be divided into two types:
- Carcass (skeleton) – drywall mounted on pre-prepared metal or wooden frame.
- Frameless – in this case plasterboard sheets are glued to the surface of the wall with a special mounting adhesive.
Frameless DIY plasterboard wall trimming methods
The first method fits the walls with minor irregularities of less than 5 mm (Pic. №1)
Clear the wall of dirt, dust, oil stains, etc. Handle the wall with primer. We can proceed directly to the installation after complete drying of the primer. Apply the adhesive along the perimeter and along the middle on a gypsum board with comb spatula. You need to put glue either on the surfaces, where you plan to mount shelves, lamps or other items. Then the board is applied to the wall and align on the level. You need to install it on the pads of 2 cm size (pieces of wood or drywall trim can be used). After drying of the glue we can apply putty and grout joints.
The second method is for walls with irregularities of up to 2 cm (Pic. №2)
We carry out similar preparatory work as with the first method. Apply glue with large heaps and steps of 20 – 30 cm on both the perimeter and the area across the drywall. Then press the sheet to the wall and align it by slight tapping on the level. Use lining pads similar to the first method.
A third method for walls with large defects and irregularities (Pic. №3)
To start, you’ve got to prepare the surface following the technology described in the first method. Cut strips of plasterboard in 10 cm width. Then, paste them on the walls around the perimeter, after it sticking the vertical bars on the surface of the walls with 60 cm interval. After drying, fasten gypsum boards as it was shown in the first method.
DIY plasterboard wall trimming. Carcass way
Option 1 and 2 are suitable for walls with irregularities up to 10 cm. The drywall is attached to a wooden or metal frame, which is fixed to the wall with screws and dowels. Generally, frame is made of guide profile DP 50 (65; 75; 100) * 40 and rack profile RP 50 (65; 75; 100) * 50. The rack profile is installed in form of parallel lines with a gap of 60 cm between the lower and upper guide. Hinge profile connection is applied: vertical profile fits into the bottom and top and secured with screws.
Option 3. This method is suitable for the walls with irregularities more than 10 cm. Here we use a system of false ceiling: direct suspension, guide profile DPC 28 * 27 and the ceiling profile DC 60 * 27. The guide profile of the carcass is attached through the tape seal (you can use anchors sealant) in step of no more than 100 cm. Ceiling profile is attached to the wall using direct hangers in interval of 150 cm. The lower and upper suspension are mounted on the floor and ceiling at a distance of 15 cm. We use not less than 3 hangers for mounting of one ceiling profile.
