Construction technology
The base should be solid, clean, and free of visible water, with no sand or powder on the surface. The holes in front should be sealed and repaired in advance.
Open the packaging, pour the powder into a container that has been weighed with water, and use a blender to stir it into a gel like sand. It is recommended to let it stand for 3 minutes after stirring, and then stir again for better construction condition of the material.
Use a scraper or spatula for regular scraping, and the next step should be carried out after the previous step has dried completely.
After mortar construction, it needs to be cured for 7 days until the interior is completely dry before applying putty and coating on the surface.
Reference amount
1.5kg/m2/mm (actual usage depends on the roughness of the base surface, environmental factors, etc.)
Precautions
The construction temperature is between 5-35 ℃, and the relative humidity is ≤ 85%.
The mixed mortar should be used within 2 hours, and it is strictly prohibited to add water to the dried mortar for mixing.
If scraping on the surface of concrete walls or ceramic tile adhesive, the smooth base surface needs to be roughened before leveling construction.
For the base layer with high water absorption rate, it is necessary to apply interface agent or wet it with water before construction.
Transportation and storage
Avoid rain and sun exposure during transportation. Store in a cool and dry warehouse to prevent moisture and strictly prohibit contact with water.
