Yes.
Saint-Gobain’s aldehyde putty series uses natural gypsum as the main material, plus imported environmentally friendly additives. It is made of a patented environmentally friendly formula and can be used by just adding water and mixing. When gypsum is mixed with water, it quickly changes from semi-hydrated gypsum to dihydrate gypsum. The dihydrate gypsum crystals are closely combined with each other, making the hardened gypsum become an artificial stone with higher strength.
The direct bonding force of the crystal is 1,000 times the bonding strength of the glue. The volume of the partner building gypsum expands by about 1% during the crystallization process, making the surface and edges of the wall smooth and plump, and it does not crack when dry.
Precautions for the use of putty
Cracked putty needs to be eradicated. If the cracks are not too large, flexible putty can also be used for the first layer of construction, and then proceed according to the standard construction method. construction. ?
Each layer of construction should not be too thick. The time interval between two layers of construction must be more than 4 hours. The previous layer of putty should be completely dry before applying the subsequent layer.
