1. Construction preparation.
1.Confirm that the construction environment meets the requirements, the temperature is suitable, the air is dry, and the ventilation is good.
2.Prepare construction tools and protective equipment.
3.Prepare enough DPS permeable crystallization waterproofing agent and supporting materials.
Second, grassroots treatment.
1.Clean up the floating dust, oil stains, loose objects, etc. on the surface of the base layer to ensure that the surface is clean and solid.
2.For defects such as cracks and honeycombs, repair and level are carried out to ensure that the base layer is smooth and free of potholes. Keep the base layer dry.
3. Stir the ingredients.
1.According to the ratio of the product manual, the DPS permanent condensate permeation crystallization waterproofing agent and the supporting materials are mixed. Stir well to ensure that the mixture is even, no particles, no precipitation.
2.The stirred material should be used up within the specified time and avoid long-term storage.
Fourth, spraying. 1.The stirred DPS permeable crystallized waterproofing agent is sprayed on the surface of the base layer.
2.Spray evenly to avoid omissions and build-up. As needed, it can be applied multiple times, with an interval of not less than 4 hours between each application.
Fifth, curing and solidifying.
1.After the spraying is completed, it should be cured and cured to keep the surface moist and not in contact with water.
2.Curing and curing time should be carried out according to the requirements of the product manual, avoid walking on the painted surface or placing heavy objects.
6. Quality inspection.
After curing, check whether the surface is flat, free of bubbles, no cracks and other defects. Conduct a water seepage test to confirm whether the waterproof effect meets the requirements. If there is a problem, deal with and fix it in time.
