3 operating process
3.1 Process flow:
Grassroots treatment → Run oil powder → full color scraping putty → grinding paper → brush the first alkyd varnish →
Paint color → brush the second alkyd varnish brush → third alkyd varnish brush → brush the fourth alkyd varnish →
Brush the first acrylic lacquer → brush the second acrylic lacquer → sand wax → wipe polish wax
3.2 primary treatment; first remove the wood surface dust and oil. Such as wood surface contamination of oil, gasoline or thin oil can be used to scrub clean. Clear dust, oil after grinding paper, large surface can be sandpaper package 5cm square short wooden pad with grinding. Requires polished, polished, and cleaned.
3.3 Run oil powder: oil is based on the model with a large white powder color, red clay, black paint, floor yellow, clear oil, varnish and other preparation. Oil powder can not be transferred too thin to tune into a congee-shaped appropriate. Moisturizing oil brush can be wiped, when wiping with Ma Sheng rope broken into about 30 ~ 40cm long Ma rub back and forth, including the edge, angle, etc. to wipe and wipe the net. Wire angle with the horn plate scraping.
3.4 full color scraping putty: color putty from the gypsum, varnish, water and stone color from the deployment. Color putty to scratch to the net, should not leak scratches.
3.5 sanding paper: to be putty dry, with 1 sandpaper polished, after grinding with a dry cloth wipe clean. And then the same color putty full scratch second, the same requirements and scraping Road putty. Scraping with the same color putty nail and the missing angle at the corner of the putty putty, wiping the full formation. Dry sanding paper, polished smooth, so that grainy clear, not worn edges and corners, after grinding clean, and wipe with a damp cloth, dry.
3.6 Brush the first alkyd varnish: brushing when the horizontal and vertical, thin and thick uniform, no flow stone fall, smooth brush pattern, not allowed to leak brush, dry sandpaper with 1 sanding, and wipe with a damp cloth, dry. After each interval of paint generally summer about 6h, spring and autumn about 12h, about 24 hours in winter, conditional time a little longer and better.
3.7 points paint film repair color: paint film dissolved with alcohol, add the right amount of stone pigment preparation. On the brush has been the first road paint putty scars, nail eyes, etc. at the repair color, paint film plus color according to the depth of the color depth of flexibility, repair the color and the original color to be basically the same.
3.8 Brush the second alkyd varnish: first check the point of paint film repair color, such as meeting the requirements can brush the second varnish, until after the sub-clear lacquer, with 1 sandpaper, wipe with a damp cloth, and then a detailed inspection, If there is leakage of putty and uneven place, need to re-coloring putty, dry after local grinding, and wipe with a damp cloth.
3.9 Brush the third alkyd varnish: to be the second alkyd varnish dry, with 280 water sandpaper grinding, wipe after grinding, the rest of the operating method above.
3.10 Brush fourth alkyd varnish: After brushing the fourth alkyd varnish, to wait 4 ~ 6d after 280 ~ 320 water sandpaper for grinding, polishing, grinding, grinding, wipe clean.
3.11 Brush the first acrylic lacquer: acrylic lacquer in two groups, one for the A group, the second for the B group, with a ratio of 40%, 60% (weight ratio), according to the climate plus appropriate dilution Agent xylene. As the paint volatile faster, how much preparation to use the number, preferably according to half-day workload calculation. Brush requires action fast, brush pattern smooth, uniform thickness, do not flow does not fall, not leakage brush, dry sandpaper with 320 water polished, wiped with a damp cloth after wiping.
3.12 brush the second acrylic lacquer: to be the first brush after 4 ~ 6h, you can brush the second acrylic lacquer, brush the methods and requirements with the first. Brush the next day with 320 ~ 380 water sandpaper grinding, grinding paper force should be uniform, from light grinding to no light until the 'spot', not worn edges and corners, after grinding wipe clean.
3.13 to play sand wax: First, the original sand wax mixed with kerosene transferred into a porridge-like, with a double cloth cloth dipped in sand and wax rubbed back and forth several times, the power should be uniform, the corners should rub rubbing, not leakage rub, Broken, until the bright stars so far. Finally, with a clean cotton dipped in gasoline will wipe the wax.
3.14 polish wax: with a clean white cloth will be wrapped in wax inside, shut tightly, rub your hand, rub evenly, wipe until the light so far. If the wood surface to do varnish grinding back without acrylic lacquer grinding retreat, the operation of the process with the above 3.2 to 3.10, plus wipe the paint surface, that is, in the fourth road alkyd varnish after drying, the rubbing alkyd varnish (Drunk acid varnish plus 10% to 15% of the alkyd thin material), with a white cloth (preferably bean bag cloth) cotton dipped in varnish wipe 5 to 6 times, so brown eyes more smooth. Drying at room temperature for 3 ~ 4d, with 400 water sandpaper to remove more than 50% of the light, commonly known as "spot". But be careful not to wear the end of the road paint and lines, edges and corners, grinding clean wipe clean. Then follow the above process (3.13) to play a sand wax, (3.14) polish wax can survive.
