The a, 10b, and 10c are arranged and fixed in the width direction. As a fixing method, a general fixing method of gypsum board is adopted. Next, the groove 13 formed in the joint portion of the gypsum boards 10a, 10b, 10c is filled with the joint treatment agent made of the above composition.

成分を第１剤に含めるのが好ましい。Here, as the joint treatment agent composed of the above composition, a first agent containing a resin having a glass transition point of -10 ° C. or less and a fibrous substance, and a second agent containing hemihydrate gypsum are prepared. However, it is preferable to adjust by mixing the first agent and the second agent so that the hemihydrate gypsum, the resin and the fibrous substance are contained in the above-mentioned proportions. This is because if the resin, fibrous substance and hemihydrate gypsum are mixed from the beginning, the composition will harden before the work, making the work difficult. When the composition contains components other than the essential components of hemihydrate gypsum, resin and fibrous substance (for example, filler), it is preferable to include the curing retarder in the second agent and the other components in the first agent.

As a result, the joint portion 11 is formed. The surface of the formed joint 11 is finished by polishing.
Finally, the cloth 12 is pasted on the gypsum boards 10a, 10b, 10c to complete the gypsum boat aggregate 10 described above.

も低下する。When the coating film 15 is formed instead of the cloth 12, the finished putty layer 14 is formed on the joint portion 11, and the surface of the finished putty layer 14 is polished smoothly. When the interior coating material is applied thereafter to form the coating film 15, the appearance of the coating film 15 is unlikely to have a step. According to the joint treatment method for gypsum board as described above, the joint treatment agent described above is used for the groove 13
Since the joint treatment is completed just by filling the joint with the above, the work is remarkably simplified and the work cost is reduced as compared with the conventional joint treatment method.
