It is used for all kinds of underground buildings or structures, cable channel, pool, kitchen and toilet, air defense caves, subways, tunnels and other rapid plugging works.
Construction Tools
1. Clean up the basic tools: a hammer and chisel, wire broom and cloth
2. Said feed ingredients: scale, mixing materials barrels (basin), bucket, hand blender
3. Feeding tools: scraper, float, brush, son
4. Plugging tool: the rods of different diameter
5. Maintenance tools: sprinkler, fill the bucket (basin), brush
Acceptance of Work
Check after the completion of the construction of waterproof layer has no empty drum, crack, peeling, pulverization phenomenon; Can do water test, but should be performed after the sclerosis of the waterproof layer;
After construction of the waterproof layer thickness should comply with the design requirements;
For damp environment of acceptance, if there is water surface of the coating, should take into account the factors of moisture condensation, if it is for this reason, it will disappear naturally after the scene drying.
Water Leakage Treatment
1. The leaking joints should be chiseled "V" shaped, the base layer should be clean, solid and dense.
2. Put plugging powder : water = 1: 0.3 ~ 0.35 into mixing basin (buckets), mixing into a paste (add more water, the setting time is longer). When the temperature is below 10°C, stirred quickly with warm water (about 40 °C). The ingredients should not be made too much once to avoid solidification;
3. Squeezing the material to "V" shaped groove or leaking cracks when the slurry slightly hot and hard, blocking with a wooden stick;
4. For seepage pits, directly put into quick setting expansive cement, and then compacting, troweling and watering conservation;
5. For serious leaking cracks, using the drainage method, first block the upper gap, and then block under gap. Perforates a hole to reduce pressure and lead the leakage water.
6. For a large area of leakage, if necessary, perforates a hole to lead the water. First plugging large leakage area, and then plugging holes ;
7. Curing time is about 2 to 3 days, watering, covering wet materials, or maintenance.
When in a moist environment such as basement or in a hardening waterproof layer, make the protective layer immediately or paste some material, which need not wet curing.
Seepage Surface Treatment
1. The base course must be wet, solid and clean, mixing plugging powder with two times the weight of the sand on rough place.
2. Mix plugging powder : water = 1 : 0.3~0.35 with a mechanical stirrer for about 2 minutes (without pellets, a fine putty-like slurry), the ingredients should not be made too much once to avoid waste.
3. Construction (2 to 3 times) coating the prepared slurry on a water surface. After the first layer to be hardened (no finger pressure traces), apply a second layer. If there is a large area of water seepage, apply the third layer. If only partial leakages, then coated a layer at seepage place until it does not leak. Each scraping must be back and forth a few times, make coverage dense between the coatings. The quantity of each layer is about 1.2kg/m², the total thickness is about 1.5 ~ 2.2mm.
Precautions
Some people are sensitive to resin product. Wear gloves and skin barrier cream when handling these products.
If contact with the resin occurs, it must be removed before it hardens with a resin removing cream such as Kerocleanse or Rozaklens skin cleanser, follow by washing soap and water. Do not use solvent.
Use of goggles is recommended. In case of accidental eye contact, wash thoroughly with plenty of clean water and seek medical advise immediately.
Ensure adequate ventilation when using resin and solvent containing materials.
The product is packed by double plastic bag. Basic packing specifications is 2 kgs/bag.
Outer packing is carton.
The material is easily to affected by damp, so it should be stored in dry room to prevent package against breakage.
Shelf life is 12 months.
