Performance Features1. Easy to use, capable of being used after mixing with water..2. The interval between initial set and final set is short, generally no more than 20 minutes.3. Strong performance in sulfate resistance and seawater corrosion prevention, good durability, anti-sulfur coefficient >1.4. Strong cohesion, easiness in firmly cohering to construction surface, non-exclusion of water when disposing large area slow penetration. 5. Innocuous, inodorous, noncombustible, non-explosive, harmless to person. Applicable Scope1. Used for waterproof treatment of rigidity surfaces of cellar, bathroom, tunnel, civil air defense, water pool etc, especially for disposal of large area slow penetration and anti-penetration and damp-proof of facilities of deep underground project.2. Used for adhering to ceramic tiles, mosaic, etc.Construction Method 1. Disposal of construction base course: before construction the base course must be cleaned without oil stain, dry powdery or other attaching, and then the base shall be moistened sufficiently with water but without ponding water. The construction base must be rigid. 2. Preparation of slurry: mix high efficiency anti-seepage agent with water at the water-material ratio ranged from 0.25 to 0.5, the proportion of added water shall be based on the operation requirement (be thin for painting and thick for plastering). At the initial stage of mixing, the ratio shall be 0.25, and for 5 minutes mixing the operator shall confirm whether to add water or not. If the slurry is mixed to evenness in 5 minutes, another 5 minutes are needed to lay it still, and the slurry can be used after remixing it for 1 minute. The slurry must be used up within 1 hour.3. Construction operation: When doing the first coating, the thick slurry shall be prepared (the water-material ratio shall range from 0.2 to 0.40) and plastered and painted with scraper. Upon basic rigidification of the first coat, the second coat shall be continued, and the thin slurry shall be prepared at the ratio ranging from 0.45 to 0.5 and painted with brush. If necessary the third coat can be made. 4. Maintenance: Concerning maintenance of coat, the spraying is needed after its final set (no print when being touched with fingers), and plastic film shall be covered on it for wetting. In case of quite dryness or sunshine irradiation, the outdoor coat shall be covered with straw matt and moistened for 3 days.Notices for UseThe product is packed with plastic bag, with the net weight of 10 kg/bag. The product shall be stored in dryness and shadiness and be used up once after unpacking...
