209 concrete interface treatment agent

1. Product Description

209 concrete interface treatment agent is formulated from high molecular polymer emulsion and a variety of additives. This product has good adhesion. When used in the construction of new and old concrete, air-entrained bricks and other materials, an interface bonding layer is formed on the surface, which improves the bonding strength and solves the problem of hollowing and falling off between the bonding layers. question. It has good water retention, water resistance, alkali resistance and frost resistance. The effect is good in construction.

2. Reference dosage

The reference dosage of 209 concrete interface treatment agent is 0.2-0.25kg/m2.

3. Construction and Precautions

1. Before construction, clean up the loose soil, oil stains and other dirt on the surface of the base layer, and spray it with clean water before construction.

2. Pour the interface agent into the container and use mechanical spraying or roller coating. No omissions are allowed.

3. It acts on the bonding layer of new and old concrete to avoid chipping. After repairing the old concrete pavement and applying interface agent, the next step of construction can be carried out. Or wait until it feels slightly sticky to the touch before proceeding to the next construction step.

4. The ratio of this product to cement and clean sand is 1:1.5:2 (mixed into a paste) and can be used to repair concrete holes or walls.

5. Construction temperature, it is not suitable for construction outside on cloudy and rainy days. The prepared materials should be used up within 2 hours and should be prepared as needed.

3. Packaging and Storage
