Wood paint construction process:
Substrate finishing treatment → first primer coating → putty → second primer coating → topcoat brushing.
Wood lacquer construction method:
1. Painted furniture before painting should be degreased, decontaminated, and smoothed.
2. Use the matching water-based primer, the primer is prepared according to the product specification, stir evenly, and then dilute to the construction viscosity with water according to the situation. Filter with crepe cloth and place it for 20 minutes to mature. The primer should be painted thin and uniform for the first time. After drying for 3 to 4 hours (25 ° C, 50% humidity), sand it with sandpaper.
3. Depending on the depth of the wood grain, the putty should be scraped thin as well. When applying the putty, apply the force to scrape into the wooden seam. After the putty is dried, use sandpaper to polish it thoroughly.
4. Apply 1~2 times of primer on the putty or the first primer. After the primer is dried, sand the paper with a sandpaper to make the substrate smooth and smooth.
5. The topcoat is prepared according to the ratio of the product description. After mixing the main paint and the curing agent, intermittently stirring for 10 minutes, then diluting with water to the construction viscosity according to the situation, filtering with crepe cloth, leaving it for 20 minutes to be matured. The top coat is generally applied 1~2 times. If higher fullness is required, the number of top coats can be increased. The overcoating time is within 2~16 hours (25°C, 50% humidity), topcoat and topcoat. There is no need to polish between the two. If the overcoating time exceeds 16 hours, it should be polished and then painted. Before applying the last finish, after the paint film is fully dry (about 12 hours), gently dry or wet the unevenness with a 1000-mesh sandpaper and wipe it clean, then apply or spray the last finish.
Wood lacquer construction precautions:
1. Wood lacquer should be brushed after completion of ground construction. Keep it ventilated during construction, no dust, so as not to affect the overall effect. Wood lacquer and latex paint can not be constructed at the same time.
2, the wood should be dry, the water content should not exceed 15%, the construction environment humidity and temperature should not be too high.
3, the paint products are mostly three components (main paint, thinner, curing agent), stir evenly before mixing, strictly proportional to paint.
4, use the matching thinner, curing agent, so as not to cause biting the bottom, wrinkle.
5, after the deployment is good to filter, still 10 to 15 minutes to paint.
6. After placing the paint for a period of time, add a proper amount of thinner to avoid the viscosity increase and the brush marks.
7. The finished paint should be used up within 4 hours. If it is not used up, it should not be returned to the original paint bucket.
8. The construction area should not exceed 4-5 planks to avoid brush marks.
9. The coating film should not be too thick at one time. It must be finished after the coating film is dried.
10, the primer should not be thick, thin one layer. The topcoat should not be applied too thick at one time, otherwise it will affect the drying speed and hardness.
11. Before the construction of the wood lacquer, it must be thoroughly polished until the whole paint film is smooth and flat, avoiding the poor adhesion between the layers and causing the layer to rise.
12, polishing must be done after the actual dry, otherwise there will be haze or whitening.
13. If the ambient temperature is lower than 7 °C or the humidity is greater than 85%, it can not be applied, otherwise it will easily cause whitening and other defects.
