Calcium silicate board ceiling of the joints with what will not crack it?

Calcium silicate board ceiling of the joints with what will not crack it?

Answer:

With the agent group seam experts can solve the problem. Seiko joint experts for high environmental protection products, hard work in the seams at the formation of high-density polymer white film. The white film toughness, dense and strong, wear-resistant, water, corrosion resistance, no yellowing, no color, with a strong tensile properties and adhesion.
First analyze the cause of cracking. Calcium silicate board ceiling cracking for three reasons: First, keel problems. If the use of light steel keel, the thickness of more than 0.8 mm, if the thickness of the wood keel to 3.5 cm or more. To ensure that the seams on the edge of the screw effectively locked in the same keel. Second, leave the seam problem, you must ensure that more than 5 mm left seam.Three is the seam material problem, to ensure that the joints in the material into the powder and cellulose construction If the thickness of more than 6 mm, the best hanging plastic several times hanging, and so on the layer of glue dry and then hang a layer of glue, dry after hanging on the glue and other joints with dry after the best and then linked to white plastic The last seam belt, so that the dry environment in the north will not crack in the south even more problematic.
Because you are in the construction of the time did not follow the requirements in the middle of the calcium silicate board to stay shrinkage 5mm, about it. Has been cracked place with a hand saw a gap, and then use calcium silicate board special sealing material seal, plus a joint belt and then on the seam material felt later on the paint
