When the floors are tiled and fixed on the wooden joists, special spiral nails should be used (available in decoration materials stores), and the tongue and groove between each floor must be closely spliced without leaving gaps, but attention should also be paid to the humidity of the environment when paving. When the environmental humidity is high, the hand feel should be lighter when nailing the floor, and when the environmental humidity is low, the opposite is true. When paving, it is forbidden to glue between the tongue and groove of each floor before splicing, which will destroy the natural stress of the floor and make the floor crack. In addition, according to the characteristics of the climate in Shanghai, the floor should naturally have an expansion joint of about 10mm around the room to adapt to the changes of floor expansion and contraction.

4. The adhesive used for laying parquet floor should be evenly coated, the floor should be arranged closely and the flat-fell seam should be even. Every room should be paved from the intersection and spread around. One side of parquet floor along the cross line must be paved with seams. After each parquet floor is paved, the extruded glue should be wiped off at will.

5. After the completion of the whole paved parquet floor, before cleaning, rough planing, fine grinding and planing, the adhesive should be dried first, and the corners should be manually polished with fine wood sandpaper.

6. After polishing and cleaning, the surface layer should be embedded with putty of the same color as the floor. After drying, it should be polished with fine sandpaper and painted with floor paint.
