1. Acceptance of air tightness

Air tightness is mainly reflected in the resistance to external stains, water, oil and other pollutants. Ordinary concrete sealing and curing agent floor can effectively prevent the intrusion of pollutants, but it is not absolutely

The antifouling performance of the floor after construction should be better than the original floor, including two parameters: penetration time and penetration

2. Acceptance strength

The best strength of concrete sealer floor can reach 8-9 degrees of Mohs hardness, but not all floors use this as an acceptance criterion after construction

Generally speaking, the ground strength after construction is greatly improved than the original ground. The minimum standard is no ash, no sand, no scars when scratched with non-sharp metal objects

3. Dust proof acceptance

Dust protection is the minimum standard for concrete sealer floors and applies to all floors that use concrete sealer

4. Acceptance brightness

The improvement of the ground gloss by the concrete sealing and curing agent is mainly reflected in the fact that after the cement pores are filled, the original light diffuse reflection is more converted into specular reflection to increase a certain gloss.

In order to obtain high gloss, such as a mirror effect, it needs to be mechanically polished. This is mainly determined according to customer requirements, there is no uniform standard

5. Check and accept the anti-skid performance

Concrete sealer and conditioner floors, whether high gloss or matte, must not be slippery, otherwise waxing is suspected during construction. Cut corners unless approved by Party A
