3 operating process
3.1 Process flow:
Grassroots treatment → polish oil powder → full scrubbing oil putty → brush oil color →
Brush first pass varnish (brush varnish → patch putty → repair color → frosted paper) → install the glass → brush the second time the varnish →
Brush the third pass varnish
3.2 Primary treatment: first wooden doors and windows and the surface of the grass-roots surface of the dust, oil, spots, traces of plastic with a scraper or broken glass scraping clean. Be careful not to scratch the burrs, and do not scratch the walls. And then use more than 1 sandpaper along the grain polished, the first grinding angle, after grinding four flat, until smooth so far.
Wood doors and windows grassroots small pieces of living Alice, the available knife tore. Heavy skin where the application of small nails nail firmly, such as heavy skin or a burned scar, should be woodworking repair.
3.3 polish oil powder: with a large white powder 24, 16, rosin perfume 16, cooked tung oil 2 (weight ratio), etc. mixing stirring oil color (color the same board color), Sheng small oil drums. With cotton silk dipped in oil repeatedly coated on the surface of wood, grazed the bristles of the wood, and then rubbed with linen or wood, wire angle to remove the use of bamboo powder. Note that the wall and the metal shall not be contaminated with oil. To be dry powder, with 1 sandpaper lightly along the grain polished, the first grinding angle, cut mouth, after grinding four flat, until smooth so far. Attention to protect the edges and corners, do not wear the oil within the bristle eye. Polished with tidal cloth after grinding the powder, dust wipe.
3.4 full scrape oil putty: rub putty weight ratio of gypsum powder 20, cooked tung oil 7, water 50 (weight ratio), and add the color tone into oil color putty (color lighter than the template 1 ~ 2 color). Should pay attention to putty oil can not be too large or too small, such as oily, brush is not easy to immerse in wood, such as oily small, easy to drill into the wood, so brush the oil color is not easy, uniform color. With a knife or horns will putty putty nail hole, crack, bristle eye. When wiping wiping to put up, in case of large joints or knots, the application of surgery, horns will putty putty into the seam, and then smooth. Putty must be scraped, do not leave wild putty. After the dry putty, with 1 sandpaper gently along the grain polished, the first grinding angle, cut mouth, after grinding four flat, pay attention to protecting the edges and corners, grinding back and forth until smooth. After grinding with tidal cloth to wipe the powder under the wipe.
3.5 Brush oil: the first lead oil (or blending paint), gasoline, varnish, edible oil mixed with a basket (color the same board color), and then poured in a small oil drum, stirring often to avoid precipitation Resulting in inconsistent color.
Brush oil color, from outside to inside, from left to right, from top to bottom, along the wood brushing. Do not pollute the wall when brushing the window frame, brush to the connector to be light, to color the same. Due to oil-colored drying faster, so when brushing oil should be agile, requiring no strands of non-section, horizontal and vertical, brush oil to brush when the float to avoid the brush lock.
Brush the wooden window, brush the upper part of the box and then brush Liangzi; Liangzi all brushing, the hook hook hook, and then brush the sash; such as double-fan window, you should brush the left fan after the brush right fan; Brush the middle fan; Shade outside the first brush after brush inside.
Brush the wooden door, the first brush after the child brush the door frame, the door back, after brushing the door with a wooden wedge will be fixed, and finally brush the door front; all good brush, check for leakage brush, oil stained on the hardware to wipe in time .
Oil color brushing, the requirements of the same color of wood, but do not cover the grain, so every brush must be a good brush, do not leave the joint, the two brush face transfer edge do not dip each other, Timely erase, to achieve the same color.
3.6 brush the first pass varnish:
3.6.1 Brush varnish: Brush and brush the same color, but the first brush with a little varnish should be slightly more easy to quick-drying materials. Due to varnish viscosity, the best use has been used to brush the mouth of the old brush, brush to pay attention to not flow, do not fall, brushing evenly. Until the varnish is completely dry, with 1 or old sandpaper thoroughly polished again, the head over the varnish surface of the basic polished away, and then tidal cloth to wipe the dust.
3.6.2 Putty Putty: Generally, it is not necessary to putty after brushing oil. In special circumstances, you can use oily slightly colored gypsum putty to repair the incomplete and incomplete parts. When you operate, you must use horn plate scraping, , Putty to close clean, smooth and no scratches (with putty points must be treated with paint film).
3.6.3 repair color: wood on the surface of the spots, knots, putty scar and wood color inconsistencies, the application of paint films, alcohol plus color deployment (color the same board color), or with a light to deep lacquer blending paint and dilution The color depth of the repair should be shallow, shallow deepening, the depth of the color of the wood into a color, and draw the grain.
3.6.4 Frosted paper: use a fine sandpaper gently grinding back and forth, and then wipe the powder with a tidal cloth.
3.7 Installation of glass: see the glass installation process standards.
3.8 brush the second pass of the varnish: should use the original barrel varnish without diluent (winter can be a little drier), brush the oil operation with the former, but the brush oil action to be agile, multi-brush management, varnish brushing full agreement , Do not flow does not fall, bright uniform, brush and then carefully check it again, there are problems to be corrected in time. Brush this clear varnish, the surrounding environment should be clean, should be temporarily prohibited access, and finally the wooden doors and windows hooked with a very hook or fixed with a wooden wedge firmly.
3.9 brush the third time varnish
To be the second time after the varnish dry, the first to be polished, and then over the water, and finally brush the third time varnish; brush with the former law.
3.10 winter construction: indoor paint works should be carried out under the conditions of heating, room temperature to maintain a balance, the general construction of the ambient temperature of the paint should not be less than +10 ℃, relative humidity should not be greater than 60%, not a sudden change. At the same time should be responsible for setting temperature and temperature of the doors and windows, in order to facilitate ventilation to exclude moisture.

5 protection of finished products
5.1 Every time before painting, should be the ground, windowsill clean, to prevent dust, affecting the quality of paint.
5.2 Every time after the paint, the windows and doors should be hooked with hooks to prevent the door and window fans, box paint bondage, damage to the film, resulting in repair and injury fan live.
5.3 Brush the oil should be dripped on the ground or windowsill and pollution on the wall of the oil point clean brush.
5.4 paint is completed, should be assigned to take care of someone.
6 should pay attention to quality problems
6.1 Leakage Brush: Leakage brush generally occurs in the doors and windows, do not take the first and rely on the hinge facet and the door window frame, the upper and lower end of the seam and wardrobe door inside, the main reason is the inner door fan Workers do not match with the carpenters, it is often under the brush to put the door did not brush installed, and later simply can not brush the oil workers (unless the door hinge unloading heavy brush); plus habits and strict control, management is not in place, etc. , Often less brush the phenomenon of paint again. Other leakage brush problem is mainly caused by the operator is not serious.
6.2 lack of putty, lack of sandpaper: lack of putty, lack of sandpaper usually occurs in the hinge slot, the upper and lower hair, tenon and nail holes, cracks, knots and edges and other defects. The main reason is the operation is not seriously in accordance with the procedures to operate due.
6.3 flow falling, wrapped Leng: paint flow fall, wrapped Leng for two main reasons, first, because the paint is too thin, the film is too thick or high ambient temperature, dry paint and other reasons, are likely to cause flow fall, wrapped Leng ; Second is due to improper operation procedures and practices, especially the edge of the door and window color separation, such as once the oil volume and the operation does not pay attention, it is often likely to cause flow fall, wrapped Leng.
6.4 brush pattern Obviously: the main oil is small brush or oil brush is not soaked open brush hard. Apply the appropriate brush, and the oil brush with a thin foam soft after use.
6.5 Rough: the main reason is the grass-roots is not clean, paint impurity or dust in the construction, resulting in rough surface paint often occurs. Should pay attention to wipe with a damp cloth, paint to be over the basket, brush oil is prohibited when cleaning or wind when brushing oil.
6.6 wrinkles: mainly bad paint quality, with the uneven distribution, solvent evaporation or drying agent caused by too much.
6.7 Hardware pollution: In addition to the operation should be fine, should be the door locks, handles, latches and other hardware after the installation (but can advance the location and hole drilling holes), to ensure that the hardware clean and beautiful.
