Before pasting the wall and floor tiles, the dust and garbage on the surface of the base are not cleaned up or there are more loose sand grains on the surface of the base, forming an isolation layer between the base and the adhesive layer. The base is too dry and not watered before construction, which causes the base to absorb the moisture in the bonding layer, and also leads to the weak bonding between the bonding layer and the base. The strength of base mortar is low, and the strength of base is not enough.

Reinforced composite wood flooring is a popular flooring material in recent years. Formal scientific name: impregnated paper laminated wood flooring. It is made of crushed logs, filled with glue, preservatives and additives, and hot-pressed at high temperature and high pressure, thus breaking the physical structure of logs and overcoming the weakness of poor stability of logs. The composite floor has high strength, uniform specifications, high wear resistance coefficient, corrosion resistance, moth prevention and good decorative effect, and overcomes the problems of scar, bug eye and color difference on the surface of logs.
The composite wood floor does not need to be painted and waxed, and it is widely used and easy to take care of. It is the most suitable floor material for the rhythm of modern family life.
