MDF, flame retardant board, decorative panel, paint-free board, fire-resistant decorative panel, etc. The surface of this board may be uneven, or there may be glue stains and dirt, etc., it is necessary to use certain construction methods to smooth the surface of the base layer Flattening, the effect of sticking out in this way is wood grain melamine paper. The specific construction steps are as follows:
1. Use oily putty to fill and repair the local defects, nail holes and plate joints on the construction base.

2. Due to the shrinkage of oily putty during the drying process, the areas with serious surface defects and large gaps need to be repaired 2-3 times with oily putty (oily putty has faster drying time, higher hardness, and wood-based materials. The combination is better. Use putty to fill the joints, and the base layer may crack in the later stage, causing the surface of the film to deform).

3. After the oily putty is completely dry, sand it with 180-mesh or 240-mesh sandpaper.

4. After grinding, the surface should be flat and smooth, and the seams should be free of cracks and bulges.

5. Before the film is applied, the construction surface needs to be painted with water-based special glue for decorative film.
