5. It's been a long time since I used it.

How has the sports wood floor been used for more than ten years, or even decades, and there is no need to polish and renovate, just replace the new sports floor.

Sanded with sandpaper and then painted and waxed, here's how to renovate and paint a solid wood floor:

1. Floor cleaning and inspection. Mainly clean up the dust and garbage in the gaps, check whether the floor is loose, and if there is looseness, you must patch the nails, pay attention to the nail butt when repairing the nails, and rush into half a centimeter, if the floor itself is high, it is necessary to rush into a little more to prevent the grinding floor from grinding to the nails.

2. Patch the seam. Use alkyd varnish to adjust the gypsum putty, add the color to be close to the color of the floor, fill the gaps and scars, and polish it after drying for two days.

3. Grinding. The main thing in this link is to pay attention to the corners to grind. Grinding the painted floor is generally smoothed with 60 meshes, then polished with 80 mesh, and then polished with 120 mesh sandpaper.

4. Clean up. Use a vacuum cleaner to suck up the dust, and then use a feather duster to clean the walls and window sills, and then suck them clean, paying special attention to sucking the dust in the gaps, because it directly affects the quality of paint and putty.

5. Brush the primer. With 3 times the thinner of the floor paint, the paint curing agent can be added by 20% more, which can dry a little faster, and it is easier to sand. Use a wool brush to make sure that the brush is sufficient, evenly brushed, especially in the crevices, to ensure that the floor does not absorb water.

6. Fill putty. The main thing is to check that the putty of the large gap has fallen off, paste both sides of the gap with masking paper, and make up the plaster with the remaining alkyd varnish and plaster of the joint.

7. Grinding. Polished with 240 mesh water sand or 80 mesh iron sand, and clean up the floating dust after grinding.

8. Batch putty. Add old powder with cellulose, add a little white glue to adjust putty, and use iron yellow, iron red, iron black, haba powder for pigments, etc., and the color is adjusted to be close to the floor, and the full batch is after adjustment. Because the gaps and scars have been repaired, this process is mainly to fill the pores and the damaged part during sanding, because the paint has been brushed, so there is very little moisture and will not penetrate into the floor.

9. Polishing and cleaning up floating dust.

10. Brush the paint for the first time. Because water-based putty is used, the paint should be thin, and it is better to add twice the thinner to the paint to make the putty absorb enough and firmly.

11. Grinding and cleaning.

12. Brush the first.

Two, three, four coats of paint. Because the paint has been brushed once, the floor has been easy to absorb color evenly, so start according to the floor color set by yourself, add the corresponding paint color essence, can not consider one time in place, to divide in three times, so that it is uniform. Before each painting, it should be sanded and cleaned with 240 mesh water sand.
