Solid wood furniture painting process

1. The main construction process

(1) varnish construction process:

Sanding grass-roots level (clean up the surface of the wood → sandpaper polishing, smoothing and buffing, sweeping with a damp cloth); brush the first varnish (add thinner, the paint film is fast-drying); scrape full of the first putty, sandpaper buffing (putty to repair the nail holes and crevices); brush the second varnish, fine sandpaper buffing; brush the third time Varnish, polish;

Wood at least 5 times, water sandpaper sanding and buffing, waxing, polishing. Note: Interval, until dry. Summer 6 hours, 24 hours in winter. Site to keep clean, no dust. Temperature above 5 degrees Celsius.

(2) mixed-color paint construction process:

Sanding the grass-roots level (sweeping dust from the grass-roots surface, repairing the grass-roots level, and flattening with sandpaper); the first full of putty scraping (mixing putty, varnish, plaster, powder water 3:6:1) → grinding → painting primer (main paint: hardener: thinner 1:0.5:1, the thickness of the primer is about 1 cm, drying for 4 hours) →

Fine sandpaper sanding → painting top coat (top coat: hardener: thinner 1:0.5:1, hardener to increase the degree of adhesion of paint, thinner to increase the dryness, too thick inconvenient construction, too thin adhesion is not good)→replacing putty for repair → grinding and wiping the third top coat brushing the second coat → grinding → third top coat → polished and waxed.

2. Construction points

Construction specification of varnish painting sanding grass-roots level is an important process of painting varnish, should be the first to the surface of the wood dust, oil and other impurities removed. On the wet oil powder is also an important process of varnish painting, construction with cotton wool dipped in oil powder coated in the surface of the wood, rubbing back and forth with the hand, will be rubbed into the oil powder to the timber Tsa eye. When painting the oil, the hand holding the oil brush should be easy and natural, the fingers gently force to move without loosening, do not drop the brush shall prevail.

Painting should be in accordance with the dip times to be more, each time less dip oil, the operation of diligent, smooth brush requirements, in accordance with the first up and then down, the first difficult after the easy, the first left after the right, the first inside after the outside of the order and the horizontal brush vertical smooth operation method of construction.

Wooden surface oil mixing construction specifications for grass-roots level treatment, in addition to cleaning up the grass-roots debris, should also be local putty inlay, sandpaper should be sanded along the wood grain. Before painting the surface layer, the application of paint chips (insect glue paint) to have a large color difference and wood fat at the knots and scars to seal the bottom.

Should be painted at the grass-roots level of dry oil or clear moor, painting dry oil layer to all parts of the uniform brush, can not miss the brush. After the base oil is dry, full scrape the first putty, after drying to hand sandpaper sanding, and then make up the high strength putty, putty to pick the wire does not fall shall prevail. When painting the top layer of paint, it should be ground with fine sandpaper first.

3. Precautions

(1) Basic treatment should be constructed according to the requirements to ensure that the surface paint painting will not fail.

(2) Clean up the surrounding environment to prevent dust.

(3) because the paint have a certain degree of toxicity, the respiratory tract has a strong stimulating effect, the construction must pay attention to good ventilation.

Indoor board surface plaster surface of the paint material to latex-based.

Panel and plaster surface of the grass-roots level:

First plaster surface cinder and pimples and other debris with a spatula shovel, and then use a brown brush to remove the surface dust and dirt. After the surface is cleaned, use putty to batch the wall flat. After the putty is dry, use a spatula to level the excess putty, and then use No. 1 sandpaper to smooth it out.

Panel splices are generally taped seam tape. Nail tail brush rust paint, and plaster putty smooth. Corner with putty embedded full paste seam tape board and plaster surface coating process: cleaning → fill gaps, partial scraping putty → grinding → first full scraping putty → grinding → second full scraping putty → grinding → third scraping putty → primer → first coat → replenish putty → grinding → second coat → third coat.

Full Scrape Putty and Sanding:

When the larger gaps in the indoor painting surface are filled and leveled, use the batch embedding tool to scrape the latex putty, all the tiny sandholes and shrinkage cracks need to be scraped to the full to be dense, smooth, neat line and corner edges to the extent that the wall should be scraped horizontally along the horizontal plane of the wall, scrape as thin as possible, do not miss the scraping, joints should not be left hewed, and pay attention not to stain the doors, windows and other objects, and not to leave the wall. Doors and windows and other things stained. In order to scrape three times putty, putty dry, with No. 1 sandpaper wrapped in a flat sandpaper frame, putty residue and unevenness in the sanding level, until smooth. Note that the force is uniform, to protect the corners. After grinding with a brown broom clean batch clean.

The first coating:

The first coating must be clean before painting the grass-roots surface, wipe clean floating ash. It is appropriate to use the rolling method of painting, painting order is generally from top to bottom, from left to right, first horizontal and then vertical, the first edge line, corners, small surface after the large surface.

There shall be no residual paint at the corners, and the corners shall not be wrapped. If the wall can not be painted from the top to the bottom, should be multi-level up and down at the same time, cooperate and collaborate with each other, to avoid hewing, brushing and painting overlapping phenomenon. Individual surface each application of the same batch of paint, and a completion.

Replacement of putty: each paint dry, should be generally checked once, if defects should be local replacement of paint putty once, and scrape with a bullhorn, so as not to damage the paint film.

Grinding: after the filler is dry, fine sandpaper should be used to smoothen the paint surface, pay attention to the force should be light and even, and shall not grind through the paint film, after grinding the surface will be swept clean.

The second painting and polishing the same way with the first.

Steps:

Sweep the grass-roots level→fill the putty, partially scrape the putty, and grind it down→first full scrape the putty, and grind it down→second full scrape the putty, and grind it down→apply the sealing primer→apply the first paint→replenish the putty, and grind it down→apply the second paint→polish it down to hand over the work.

Methods:

1, grass-roots treatment is to ensure the quality of construction of the key links, which to ensure that the wall is completely dry is the most basic conditions, generally should be placed more than 10 days. The wall must be flat, at least two full scraping putty, to meet the standard requirements.

2, latex paint painting construction method can be used hand brush, rolling and spraying. When painting, it should be operated continuously and quickly, and finished at one time.

3, painting latex paint should be uniform, there can be no leakage of brush, flow attached and other phenomena. Painting once, sanding once. Generally should be more than two times.

Notes:

1, putty should be matched with the performance of the paint, solid and firm, no chalking, peeling, cracking. Use water-resistant putty in wet place such as bathroom.

2, the paint should be stirred well, the viscosity is too large can be appropriate to add not, viscosity can be small add thickener.

3, construction temperature is higher than 10 degrees Celsius. Indoor can not have a lot of dust. It is best to avoid rainy days.
