What to Note When Using Waterproofing Admixtures for Mortar Waterproofing? 1105

Applying waterproofing mortar requires attention to several key points during the construction process. Below are some common examples:

Before construction, the base surface must be cleaned thoroughly, moistened with water but without any standing water.

Do not add water or any other liquid during the mixing process of the dry mortar or waterproof mortar.

The cement used must be a silicate type with a strength grade of 32.5 or higher, the silt content of the sand should be less than 3%, and the water content should be below 15%.

4. Waterproof mortar requires pressing and sealing at the positive and negative corners, around pipe penetrations, fixtures, and floor drain areas.

The waterproof layer on the ground should be applied at approximately 2 centimeters thick, while the walls should be around 1 centimeter.

6. The waterproof coating height must also meet the requirements to ensure the effectiveness of the waterproofing.

7. After waterproofing is complete, water maintenance is required; cover areas exposed to direct sunlight.

After completing the waterproofing, once the waterproofing layer is fully dried, you can proceed with the 48-72-hour water-tightness test.
