How to correctly apply waterproof agent?

Waterproof mortar construction: clean up the sediment, debris, oil, etc.; the ratio of the water repellent: water: ash: sand is controlled at: 0.03~0.05:045:1:2.5~4 (above 32.5R grade Portland cement, The sand and clay content is less than 3%. To ensure even mixing, the silicone water repellent should be mixed with water and then cement and sand. The wiper waterproof layer is applied in two layers (each layer is 10mm thick). Bottom first plaster 1mm, then wipe the waterproof mortar layer, when the initial coagulation compaction, with a wooden trowel ramming into a pockmark; wipe the second layer of waterproof mortar after the light compaction (if you need to decorate the construction must be rammed into a pockmark) . According to normal sprinkler maintenance, spraying cement curing agent is better.

Waterproof concrete construction: The amount of the silicone water repellent solution is 1~2% of the cement content, and is evenly mixed into the concrete, which is the same as the ordinary concrete construction method. In order to ensure uniform mixing, the silicone water repellent should be mixed well with cement, sand and stones.

Leakage repair construction: When the original base smooth surface need to be cut into hemp surface, after cleaning the floating ash, make a combination of plain mortar, wipe the waterproof mortar layer. Water leakage must be blocked at the leaking area. The yin and yang corners should be rounded and compacted. Leave the file to be shaped (width 100~150mm), and then use a mortar to make a bonding layer, then wipe the waterproof mortar layer.

Spray impermeability construction: After the silicone water repellent is diluted with 10 times of water, it is sprayed on the surface of water-absorbing inorganic building materials such as cement surface, brick, tile, limestone, and ordinary paint wall, or the surface of paper, wood, and fiberboard is used for anti-seepage and moisture treatment. , have excellent waterproof effect. For good results, the second pass can be applied when the first pass is not dry. Each kg of this waterproofing agent can be sprayed about 20 square meters per area.
