1 when the paint viscosity is too large, inconvenient to scrape the construction, can add a small amount of special diluent for dilution, in order to reduce the viscosity, add the amount of not more than 10% of the second. Note: if the user needs to dilute the polyurethane, you must use the company's matching diluent. The company is not responsible for the quality problems caused by the purchase of xylene, gasoline and other other diluent. )
2 porosity bubbles: material mixing method and mixing time is not uniformly mixing the materials; construction should be used in high power and speed of agitator. Another reason is the base is not clean, do the film should be careful before cleaning the substrate, no floating sand and dust, the base should not appear the stomatal pore, layer of coating film should be treated according to the requirement of process, prevent the damage caused by the leakage of coating.
3 drum: base sand, peeling, cracking, drying, coating the poor bond; base construction should be careful operation and maintenance, to the grassroots after drying, first coated with coating after curing, and then according to the construction technique of waterproof layer by layer coating.
4 the edge of the waterproof layer, the edge of the waterproof layer, the overlapping part of the brush, and the phenomenon of peeling off the edge of the same layer. The main reason is that the grass is not clean or not dry, close head operation is not careful, the seal is not good, the bottom layer of paint bonding force is not strong and so on. Therefore, the grassroots to ensure clean, dry, operating to be careful.
5 damaged: film layer of waterproof layer in the construction process or all of the construction finished, and not on the film curing on the human operation, or place the tool material, the film will be touched. Scratch. Construction should protect the integrity of the film.
6 construction should pay attention to fire prevention, construction personnel should take protective measures, the construction site requires good ventilation, in case of solvent poisoning.
7 found the quantity precipitation phenomenon, should mix before use, so as not to affect the quality of
8 A and B of two kinds of materials are flammable, toxic, drum, storage should be sealed, placed in a cool, dry, no strong direct sunlight ground.
9 construction temperature should be above 5.
