The leakage problem of ceramic tile facing exterior walls must be prevented. The main method is: according to the ceramic tile pasting construction specifications, leave a specified gap between the ceramic tiles, use polymer ceramic tile adhesive to paste, and then use polymer ceramic tile grout to fill the gaps.
For buildings that have already experienced leakage, you should first check the damage, falling off of the exterior wall tiles and cracking of the caulking mortar. If the problem is serious, good tiles should be attached first and the cracks should be filled with tile grout. After that, choose a waterproofing agent with good durability and use spraying or brushing to waterproof the caulking mortar. In order to maintain the long-term waterproofing effect of exterior walls, it is necessary to avoid using low-quality waterproofing agents that only have short-term effects.
