DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates to joint seal member used for sealing the joints between wallboard produced when stuck in alignment a number of sheets of wallboard on the surface of the building.

[0002]

2. Description of the Related Art In recent years, a method called an ALC method has been implemented in which a lightweight wall plate material such as ALC is vertically and horizontally aligned on an outer surface of a building to form an outer wall surface of the building. When the wall plate material is rectangular, joints generated between adjacent wall plate materials are continuous in a straight line and intersect vertically and horizontally. By filling and sealing the joint with a sealant, the joint from the joint to the wall surface is formed. Prevents rainwater from entering.

In order to carry out this joint sealing method, first, the inside of the joint and its opening edge are dried and cleaned, and a masking tape is applied along the opening edge of the joint. Next, after setting the tube loaded with the kneaded sealing material in the caulking gun, operate the caulking gun to extrude the sealing material in the tube, fill the joint, and use the spatula to remove the sealing material in the joint. After smoothing, remove the masking tape.
