Tips to Level Walls with Gypsum Board Yourself

Step 1: Prepare the Wall Surface

1. Walls must be clean and dust-free. Make grooves every 30 cm vertically and every 10 cm horizontally – they will ensure better adhesion of the glue to the wall.

2. Use a plumb line or level and a ruler to check the wall's verticality. If the deviation exceeds 2 cm, gypsum board panels should be mounted with screws – for this, a metal profile frame is required.

Step 2: Cut the Boards

1. Cut boards to size according to the wall height from floor to ceiling, minus 1 cm.

2. If hidden electrical wiring or water pipes will be installed under the gypsum board, drill holes for mounting electrical boxes.

3. Cut boards using a special knife and ruler. Place the ruler along the cut line and score the board with the knife, pressing firmly. Stand the board upright and bend it at the scored line. Score the back side of the board with the knife to complete the cut.

Step 3: Cover the Wall with Boards

1. Prepare adhesive according to the instructions on the package. Apply the mixture onto the gypsum board sheet.

2. Place 1 cm thick shims (2 per sheet) on the floor along the wall. Lean the board against the wall and lift it up to the ceiling.

3. Press the board against the wall, align it vertically and horizontally. Also check that the boards are aligned with each other. When gluing boards with rounded edges, leave a 5 mm gap between boards.

Step 4: Fill the Joints

1. Ensure that boards with cut edges are properly aligned. Mix the joint compound according to the proportions indicated on the package. Cut a piece of fiberglass mesh to the required length. Apply a layer of spackle between the boards, glue the mesh in the center of the joint, then apply another layer of compound and let it dry.

2. Make sure there is a 5 mm gap between boards with rounded edges. Fill the joint thoroughly with the compound mixture. Then apply one or two additional layers to level the surface.
