Saint-gobain putty powder
Saint-Gobain aldehyde putty series is made of natural gypsum as the main raw material, plus imported environmental additives, using patented environmental protection formula, and can be used by adding water and stirring. Gypsum mixed with water quickly changed from hemihydrate gypsum to dihydrate gypsum, and the crystals of dihydrate gypsum were closely combined, making the hardened gypsum a kind of artificial stone with high strength.
Direct bonding force of crystal
The direct bonding strength of crystal is 1000 times of the bonding strength of glue, and the volume of gypsum expands about 1% during crystallization, which makes the appearance and edge of the wall smooth and full, and stuffy.
Matters needing attention
Cracked putty needs to be removed. If the crack is not too big, flexible putty can also be used for the first construction, and then the construction can be carried out according to the standard construction method. Each construction should not be too thick, and the interval between two constructions must be more than 4 hours. After the first putty is completely dried, scrape the last one.
