How is Nippon Waterproof used?

1. stirring: firstly, pour the liquid material into the container, then slowly add the powder, and fully stir for 3-5 minutes until a uniform slurry without green powder caking and particles is formed. (It is best to use a blender)

2. Brushing: Brush directly on the base surface with a brush or roller brush, with even force and no brush leakage; Generally, it needs to be brushed twice, and the thickness of each brush should not exceed1mm; After the previous one is slightly dry, brush the next one (it is not sticky, usually with an interval of 1-2 hours), and brush the front and back vertically and horizontally, with a total thickness of1-2 mm; If the coating has cured, wet it with water before applying another layer.

3. Maintenance: After 24 hours of construction, it is recommended to cover the coating with wet cloth or spray water to maintain the coating.

4. Protection: Please pay attention to prevent trampling, rain, sun exposure and sharp injuries. Before the building is completely dry.

5. Inspection (closed water test): Please store water for 48 hours (at least 24 hours in summer and at least 48 hours in winter) in the bathroom and pool after the waterproof layer is dried, and check whether the waterproof construction is qualified, and the light wall should be subjected to water spraying test.

Precautions for use:

1, base surface treatment is the foundation.

Base treatment is the key to waterproof construction. Before construction, the surface of the base must be cleaned to ensure that it is firm, flat and clean, free of dust, oil, wax, mold release agent and other sundries. If there are defects such as pores and cracks, they must be repaired and smoothed with cement mortar in advance, and the corners of yin and yang should be painted into circular arcs. Keep the base surface moist when there is no Mingshui.

2, besmear brushs method should be paid attention to

Be careful not to miss the brush when brushing evenly; When painting twice before and after, keep the angle of vertical intersection, so as to fully cover in place; The single-layer coating should not be too thick, especially at the nozzle and corner, and should not exceed 1mm to prevent cracks after drying.

3. Preservation and protection are also important.

After 24 hours of construction, it is recommended to cover the coating with wet cloth or spray water for maintenance. Before it is completely dried, trampling, rain, exposure and sharp instrument damage must be prohibited, especially when installing sanitary ware in the later stage, special attention should be paid not to destroy the waterproof layer.

4, check carefully to prevent future trouble.

Be careful when painting, and carefully check after painting, especially the joints, yin and yang angles, nozzle and other parts; After the completion of the construction, a 48-hour closed water test should be conducted, and the closed water height should be increased as much as possible, not less than 20cm. Carefully check the downstairs ceiling for signs of water seepage or water droplets. The light wall shall be subjected to water spraying test, and the back wall shall be inspected.

5, pay special attention to

Waterproof slurry is suitable for use at 5℃-40℃ to avoid high temperature, low temperature and outdoor rainy weather; The prepared mixture must be used in about 65438 0 hours; It is forbidden to add water to the condensed waterproof slurry; Please keep ventilation after waterproof construction to make the waterproof layer dry and firm. Pure cement slurry is prohibited when the waterproof layer is plastered with bricks, and the construction shall be carried out according to the requirements of tile construction.
