Determine the ceiling width
According to the drawings, put a horizontal line on the top of the wall, use a tape measure on the left and right sides of the top of the wall, determine two points respectively according to the ceiling width, and use Mo Dou elastic line to ensure the horizontal line as the benchmark, so that the width of the ceiling at the top of the wall can be accurately determined.
Fixed wooden keel
According to the horizontal line at the top of the wall, fix the wooden keel to ensure the accurate position. If skew is found, it needs to be adjusted in time. Reinforce the wooden keel with American nails to ensure its bearing capacity. As the bearing surface, the wooden keel at the top of the wall should pay special attention to its stability.
Nail with a wedge
In order to fix the wooden keel firmly, we use wooden wedges and nails. Special attention should be paid to vertical stress to avoid unstable wedge fixation due to drying shrinkage. In order to ensure the stability, the wooden wedge is generally made of larch, which has a compact wood structure and is not easy to loosen.
Measure the ceiling height
Determine the height of the ceiling above the top of the wall, and then punch holes in the horizontal line with an impact drill. The drill bit size is generally 1.2cm× 1.2cm, and the hole spacing is about 30cm to ensure the stability of the keel.
Correction of keel position
After nailing the wooden keel frame according to the figure, measure whether it is straight or not. If it does not meet the requirements, it needs to be corrected. The position of the keel is very important, otherwise it may hit the keel when installing the spotlight in the future.
Decorative panel seal
The sealing of the facing is the last step, and the use of drywall nails can prevent the nails from rusting and loosening. Use the construction line to measure whether the ceiling is horizontal or not, and adjust it if it is uneven. The curved ceiling needs two people to work together. Ensure that the decorative panels are oriented in the same direction and the seams are uniform and beautiful. Check the decorative board for defects such as missing edges, falling corners and hammer marks. To prevent rusting, drywall nails should be painted with antirust paint. When painting, wait for the first time to dry and then brush again to ensure that every drywall nail is brushed well.
