Will the calcium silicate board shrink when it is finished or finished?
If the surface is no longer used as an external decoration, the seam can be treated with a glass gel.
Thermal expansion and contraction is a common property of all substances, but the thermal expansion and contraction coefficient of the size of the difference. Calcium silicate board in the decoration has not yet universal, the national standard can not be developed, are based on corporate standards as a product acceptance criteria.
Calcium silicate board water absorption rate of about 20%, when the temperature difference is large, prone to deformation that occurs drum phenomenon.
