How to deal with the joint (corner) between the lightweight honeycomb composite wallboard of Hangzhou Meixuan Building Materials and the main structure of the building?

The joint (corner) treatment between the composite wallboard and the main structure of the building mainly includes five steps:

Before caulking, clean the board joints and remove the foam caulking agent higher than the board surface in the joints;

Fill the joint with caulking putty and compact it, and the thickness shall not be higher than the board surface;

After the putty embedded in the seam is solidified, the putty embedded in the seam on both sides of the corner shall be leveled, and the alkali-resistant glass fiber grid cloth (width not less than 300mm) shall be folded in half along the center line, pasted on the corner, and compacted with a plastering knife;

After the first caulking putty is cured, scrape the second putty on the alkali-resistant glass fiber grid cloth, and the width of both sides of the alkali-resistant grid cloth is not less than 50㎜.

After the last joint filling putty is completely dried, smooth the joint surface with fine sandpaper or electric sander.
