Construction Method
1. Primary Surface treatment: base surface must be smooth, firm, clean, clear water, no leakage. Department must first leveling uneven, plugging leaks prior to treatment.
2. Ingredients: the liquid material with the powder mixture by weight ratio of 1:1, using an electric mixer to mix evenly, until the compound does not contain aggregate, stirring for about 5 minutes, liquid material is mixed with the powder mixes in liquid bucket within the liquid material and the powder mixed in time use, with the distribution, with a general control in half an hour spent.
3. Primer: In mixing well a 10% mixture of water, stir with rubber or plastic sheet after the uniform Scraping, closed primary side holes.
4. Coating: ⑴ to stir the mixture evenly with a rubber or plastic coated board, coated sub-three floors, each floor coated with about 0.9 ~ 1kg/m2, three coating thickness of 1.3 ~ 1.7 mm. ⑵ the coating is the interval before a layer of film drying curing sticky subject, about 4 to 8 hours, if on-site low temperature, humidity, ventilation is poor, dry and curing time will be extended to a number. ⑶ coating as even as possible, can not have local deposition, paint and grass-roots to bond with tight. ⑷ If the waterproof layer is not enough, can add a coat or several layers. ⑸ shaped parts such as pipe root, foot of the wall, rain and yin and yang angle of the coating to be focused on strengthening the process and coating the first layer coating, the Insert non-woven, and then coating the second layer of coating. ⑹ coated tools can be used roller, scraper and brush.⑺ construction is completed in a timely manner with water to tools to clean water.
5. Construction Attention: ⑴ construction temperature above 5 ℃.⑵ rain can not construction, construction after 4 hours can not encounter rain. ⑶ film construction is completed has not yet solidified, it is desirable to protect against damage waterproof layer.
Packaging, transport, storage 1. Packaging: This product is liquid, powder two-component 50kg / set. Liquid material is plastic drum, 25kg / barrel; powder was packed in bags, 25kg / bags.
2. Transport: This product is a general chemical goods, safe transportation, to avoid the sun and rain and hit down, to prevent packing damage.
3. Storage: fluid materials, powder to be stored in a cool, dry, ventilated warehouse and storage temperature above 5 ℃.
4. Shelf: Under normal storage, transport conditions, product storage period of six months from the date of production.
