To choose substrates, bonding glue and construction tools with high quality. Nowadays, the most common base materials in the market are plywood, MDF, particle boards and so on. While choosing, it should be paid attention to the moisture content, flatness parameters and so on, especially when the substrate surface is required to use sanding and release treatment. Bonding glues are suggested to be good brand with high quality. Construction tools can be titanium tool steels and construction have to be all cut from one side of the sheet.
The back of HPL and the surface of the substrate need evenly be coated with glue. If the substrate surface is not very even or strong absorbent, it will be required to use glue twice to make the surface curved and covered with glue.
To make glue under the back of HPL and the surface of substrate evaporate bonding requirements. It is noted that because of season, climate, area, the glue of different brand will have different volatile time. It is essential to follow the instructions on the glue package with the practical experience and concern the construction conditions to decide the volatilization time.
To stick HPL sheets carefully onto the substrates. Note: When the HPL is pressed up to the substrate, the air between substrate and HPL should be kicked out, and put forth with a rag roller, to make sure the glue can be evenly distributed while avoiding residual air inside followed by trimming ,cleaning and other post-operation.
