How long can I stick bricks after waterproof decoration?
1. The waterproof materials selected for home improvement are generally similar to cement-based materials. Because cement-based materials need to react with the wall or concrete members of the structure for a period of time before penetrating into the structure, it is best to wait for this reaction time before paving the pavement.
2. After the waterproofing of the family bathroom is finished, in order to avoid water seepage or water leakage on the bathroom floor, a closed water test will be conducted. This test is to put 5 cm deep water in the bathroom, and generally observe whether there are any signs of leakage downstairs after 24 hours. But to be on the safe side, it's best to guarantee 48 hours. Just as we see whether the water level drops, for example, whether we can see the water level drops or obvious leakage marks downstairs, we must take other measures to re-construct waterproofing.
3. The toilet generally belongs to the caisson position, which will be lower than the structural floor by a certain elevation, usually about 450 mm lower. Therefore, after waterproofing, in addition to checking for water seepage, it is necessary to backfill it again. When backfilling, light materials, such as slag of autoclaved aerated concrete blocks or light clay materials, will be used for backfilling. After backfilling, find a slope, and then construct a cushion of about 5 cm after leveling, so that after the construction is completed.
4. After the toilet backfill is completed, before preparing for the paving process, it is best to check the compactness of the ground pavement, that is to say, it needs to be stable for a period of time to see if the backfill material will sink, because sinking will lead to ground cracking, and there will be quality hidden dangers after the floor tiles are paved. Therefore, stabilizing the ground and pavement for 24 hours is also conducive to reducing the occurrence of quality problems in the later period, otherwise the impact of ground subsidence or cracking will be greater.
Therefore, it is best to finish the above work within 48 hours after the bathroom is waterproof, and then consider laying floor tiles.
