Placement template

Put the template in place first, and cut the high-quality work board into an arc similar to the above picture, but don't make the lower corner into a sharp corner, and have a plane of about 5 cm, otherwise it will be difficult to operate.

Fixed arc plate

Fix the arc-shaped panels with a spacing of about 40 cm, and the spacing between the lower corners of the two panels at the corner is about 4 cm.

Bottom fixing

White glue, plywood backing 10 13 code nail fixation. At the intersection of the four corners, apply some white glue on the back with a small board head and fix it with an air gun. You don't need to pour the whole seam back, just pour a little in the middle.

Cutting gypsum board

On the back of gypsum board, wallpaper knife is used to cut strips with a spacing of 2 cm, and the depth is about one third. Break it gently and try not to break it.

♀? Determine according to the actual situation

Then paint the plywood surface, carefully fix the cut gypsum board along the arc from bottom to top, and leave 4 mm seam at the junction of the four corners normally, so that the treated mud grid will not crack.

construction sequence

When making an arc, the virtual light modeling at the back should be done at the back, otherwise it will have a great influence on the construction in front.

Matters needing attention

Great white (putty) had better not be scraped on the board, there will be a hidden danger of bursting. Wood expands when it is wet and contracts when it is dry.
