The adverse effects caused by defects in the floor base layer

Answer:

1. Low intensity. When the bonding strength between the base layer and the epoxy resin coating is less than 1.5MPa, it is easy to cause ground cracking during use.

2. Waterproof and moisture-proof defects. The drawbacks of coating, such as delamination and pinholes, are all due to inadequate waterproof and moisture-proof treatment during the base layer, which causes the moisture in the soil to rise to the surface layer through the capillary action, seriously affecting the adhesion between the floor coating and concrete.

3. Lack of grounding point. According to experts at www.dpwang.com (China Flooring Industry Network), the biggest concern when making anti-static flooring is this. Because it will seriously affect the discharge of static electricity, and further affect the performance of epoxy anti-static flooring. Generally, we should set up a separate grounding system for anti-static flooring, which cannot be shared with lightning protection down conductors.

4. Loose. The loose base layer will greatly increase the construction cost of the floor, as a large amount of primer is required to fill it.
