Traditionally, as an interior base for buildings, etc., base panels are arranged on the wall surface, and the joints formed between these base panels are filled with β-type hemihydrate gypsum as a base material, and fillers and adhesives are applied to this base material. After filling with a base joint treatment material obtained by appropriately mixing additives such as a properties imparting agent, a viscosity modifier, a setting modifier, and a coloring agent, a finishing joint treatment material is applied on top of this with a spatula, etc. The joints were finished smooth.

However, when kneading the base joint treatment material based on β-type hemihydrate gypsum, the mercury content is 60% to 65%.
As a result, the amount of moisture evaporated during drying is large, resulting in a large thinning of the joint treatment material, which results in a large number of joint treatments (this results in poor work efficiency, and the low surface hardness makes it difficult to use finishing joint treatment materials). The problem was that it lacked adhesion with other materials.

In addition, a method has been used in which aggregate such as vermulite or powdered perlite is mixed into the joint treatment material for the base to prevent wall thinning, but in this case as well, the aggregate itself is layered or Since it is a powder, it has a high water absorption rate and therefore increases the amount of water mixed in, so it cannot be said to be effective as a means for preventing double oxidation.

The joint treatment material constructed in this way has an increased supporting capacity, and since the lightweight aggregate has a property of not easily absorbing water, the total amount of mixed water can be reduced, and therefore, there is less double lining, and it has good adhesive properties. is good. However, in this case, if the lightweight aggregate is less than 1% of the total amount, it will have little effect, and if it exceeds 20%, it will be difficult to knead unless the amount of water mixed is significantly increased, which may cause problems. Become. Furthermore, even if the bulk specific gravity and particle size distribution of lightweight aggregate exceed the specified range, or if the bulk specific gravity of α-type hemihydrate gypsum is less than 0.7 or more than 0.7, the particle size distribution is 297μ.
If the cross line width exceeds , the cross line width increases and the surface hardness and adhesiveness decrease.
