The construction requirements for moisture-proof gypsum blocks involve several aspects. First, before construction, ensure the substrate is firm, flat, and dry. The substrate should be thoroughly cleaned, removing dust, oil, and loose materials to ensure good adhesion between the gypsum blocks and the substrate. Appropriately moisten the substrate to prevent the gypsum blocks from absorbing moisture too quickly and cracking.
During construction, use suitable mortar or adhesive, mixing it according to the recommended ratio. Laying the gypsum blocks should begin from the corner or baseline, maintaining horizontal and vertical alignment to ensure neat arrangement. Leave appropriate gaps between each layer of blocks for filling and repair.
After completion, the surface of the gypsum blocks requires proper curing. Maintain appropriate humidity in the construction environment to prevent surface cracking. During curing, avoid direct sunlight and strong winds to ensure the gypsum blocks harden evenly and fully.
