Caster material process requirements Notes:

1. When the viscosity of the coating is too large and it is inconvenient to carry out scraping construction, a small amount of special thinner can be added for dilution to reduce the viscosity, and the amount added shall not be greater than 10 percent of material B.

2. Stomata and bubbles: The material mixing method and mixing time do not make the material evenly mixed; a mixer with high power and rotating speed should be used during construction. Another reason is that the treatment of the base layer is not clean. The base layer should be carefully cleaned before coating, and there should be no floating sand and dust. There should be no pores on the base layer. cause leakage.

3. If it is found that the material has precipitation, it should be stirred evenly before use, so as not to affect the quality.

4. Coating film warping: The edge of the waterproof layer and the overlap of the sub-brushes appear to be peeled off and warped from the base layer. The main reasons are that the base layer is not clean or dry, the operation of the end head is not meticulous, the sealing is not good, and the adhesion of the primer coating is not strong, resulting in warping. Therefore, the base layer should be clean and dry, and the operation should be meticulous.

5. Drumming: the base layer has peeling, sanding, cracking and non-drying, which makes the coating film poorly bonded; the construction of the base layer should be carefully operated and maintained. After the base layer is dry, apply the primer first, and after curing, press the waterproof layer The construction process is painted layer by layer.

6. Pay attention to fire prevention during construction, construction personnel should take protective measures, and the construction site requires good ventilation to prevent solvent poisoning.

7. Damage: During the layered construction of the waterproof layer of the coating film or after all the coating film is constructed, the coating film is damaged by operating activities or placing tools and materials before the coating film is cured. scratched. The integrity of the coating film should be protected during construction.

8. Both materials A and B are packed in iron drums, which are flammable and toxic. They should be sealed during storage and placed in a cool, dry place without direct sunlight.

9. The caster construction temperature should be above 5 degree .
