Construction process

First, the base surface treatment:

The surface of the concrete foundation is treated to remove the surface of the surface of the cement, the surface of the cement paste or the loose particles to expose the solid base layer, and to remove surface sand, dust, grease and the like.

Second, material preparation:

1. Check the product packaging, specifications, model, and production date to ensure that the product is within the warranty period specified by the manufacturer.

2. Open the package lid and check that the A material, B material and C material are not damaged, leaked or damp and agglomerated. The assembly ratio in each barrel is A material: B material: C material=1:3:16 .

3. When mixing the ingredients, firstly mix the A material and the B material into the barrel according to the ratio of 1:3, stir and mix evenly, then slowly add the C material while stirring until it is stirred into a uniform clay.

Third, the construction instructions:

1. According to the construction requirements, use the spatula to apply the prepared clay to the repaired parts. When applying, it should be smeared with compaction. After 3 to 14 days of completion, it can be put into use.

2. The reference dosage is about 2000kg/m3.

Precautions

1. The prepared glue should be used up within 45 minutes. It is strictly forbidden to use the cement which is not evenly mixed or has been in the initial setting state.
