Hand brushed polyurea HBPUA types
1. Single-component hand-brushed polyurea "JCHBPUA-001", is a single-component polyurea waterproof material ready to use. Its purpose is mainly waterproof and expansion joint filling.
2. Two-component hand-brushed polyurea "JCHBPUA-002" is a two-component polyurea material. Its main purpose is waterproof and corrosion-resistant. It can be used on outdoor concrete or tile foundation floors. Its performance is second only to sprayed polyurea "JCSPUA-001", with 300% elongation, excellent weather resistance and waterproof performance.
3. Polyurea self-leveling "JCHBPUA-SL001" is a load-bearing polyurea floor material, suitable for indoor workshops and garage floors, or corrosive workshop floors. It has excellent physical and mechanical properties, the surface hardness can reach 7H, and it is waterproof and corrosion-resistant.
Application scenarios of hand-brushed polyurea HBPUA
Pools, outdoor concrete or tiled floors, reservoirs, workshops, terraces and other floors that require waterproofing.
How to use polyurea HBPUA by hand brushing
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. HBPUA is mixed evenly according to the label ratio and used within 20 minutes. The minimum unit consumption of all polyurea materials is 1.8 kg per square meter.
Precautions for hand-brushing polyurea HBPUA
1. The ground must be completely closed and no air holes are allowed.
2. Mix HBPUA 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%.
