How to use SPUA "JCSPUA-001" in Jiancheng
1. Base grinding, crack cutting treatment, and vacuum clean;
2. How to use the "JCEPDT-006" primer, apply the polyurea primer brush once, and there is whitening on the ground, and re-coat locally. "JCEPDT-006" is stirred evenly according to the label ratio, apply it evenly once with the medium-hair roller, and use it within 30 minutes.
3. How to use the sealing layer of the "JCEPZT-007" intermediate paint, and use a full batch of "JCEPZT-007" intermediate paint + quartz sand, stir evenly according to the label ratio, use a push knife to scrape it evenly, and use it within 30 minutes.
4. How to use "JCSPUA-001" spray polyurea, use a professional high-pressure sprayer to perform spraying operations at a discharge speed of 1.1:1 to ensure that the discharge is consistent, the mixing is even, and the material cannot be deviated.
5. How to use "JCSPUM-001" polyurea topcoat, mix evenly according to the required ratio of the label, use an airless sprayer or a roller brush, apply evenly to ensure no bottom exposure phenomenon. Light colors can be constructed in two times, and the mixed materials must be used within 20 minutes.
Notes on using "JCSPUA"
1. The ground must be completely closed and no air holes are allowed.
2. Mix SPUA evenly, control the discharge speed, ensure that the two components are discharged at the same time, and there is no deviation in the material.
3. The two-pass construction interval should not exceed 48 hours. After it exceeds, it must be polished.
4. The ground moisture content should not exceed 8%.
