  • Detail

Wood paint refers to a kind of resin paint used on wooden products, including polyester, polyurethane paint, etc., which can be divided into water-based and oil-based. According to gloss, it can be divided into highlight, semi matte and matte. It can be divided into furniture paint, floor paint, etc. Wood lacquer makes the surface of wood furniture smoother, avoids the direct scratch and scratch of wood materials by hard objects, effectively prevents moisture from penetrating into the interior of wood and causing decay, and effectively prevents the drying and cracking of wood furniture caused by direct sunlight

the meaning of wood paint construction

wood paint refers to a kind of resin paint used on wooden products, including polyester, polyurethane paint, etc., which can be divided into water-based and oil-based. According to gloss, it can be divided into highlight, semi matte and matte. It can be divided into furniture paint, floor paint, etc. Wood lacquer makes the surface of wood furniture smoother, avoids the direct scratch and scratch of wood materials by hard objects, effectively prevents moisture from penetrating into the interior of wood and causing decay, and effectively prevents the drying and cracking of wood furniture caused by direct sunlight

wood paint construction process

(1) varnish construction process:

clean the surface of wood → Sanding paper polishing → Shangrunbo powder → Sanding paper → Fully apply the first putty and polish with sandpaper → Apply putty for the second time, and polish with fine sandpaper → Apply oil color → Brush the first coat of varnish → Spell out the color, refill the putty, and polish with fine sandpaper → Brush the second coat of varnish

fine sandpaper polishing → Brush the third coat of varnish and polish → Water sandpaper polishing, fading, waxing, polishing

(2) construction process of mixed color paint:

first, clean the dust on the surface of the base course and repair the base course → Flatten with frosted paper → Paint flakes at knots → Priming and puttying → Apply dry oil → The first full puttying → Polishing → Brush primer → The primer is dry and hard → Painting surface course → Refill putty for repair → Polish and wipe the third coat of finish paint and brush the second coat of paint → Polishing → The third finishing coat → Polish and wax

precautions for wood paint construction

1. Do not construct at the same time with latex paint

wood paint products contain toluene diisocyanate (TDI). If wood paint and latex paint are constructed at the same time, these TDI in free state will react chemically with the components in latex paint, making the wall painted with latex paint yellow

therefore, wood paint and emulsion paint cannot be applied at the same time. It is recommended to brush the wood paint first and then the wall paint to prevent the components in the wood paint from polluting the wall

2. Prevent hardware pollution

no matter what process is used, protect the hardware on the workpiece with masking paper to prevent the hardware from being stained with wood paint

in addition to the careful operation and timely cleaning of contaminated places such as non hardware, it is necessary to paint first, and then install door locks, handles and bolts, etc. to ensure that the hardware is clean and beautiful

3. When mixing, choose the supporting product

wood paint. During construction, if water-based wood paint is selected, it only needs to be diluted with water in proportion. If nitrocellulose paint and polyurethane paint are selected, relevant curing agents and diluents need to be added, and they must be prepared in strict accordance with the fixed proportion

therefore, it is best to have professional guidance during the construction of nitrocellulose paint and polyurethane paint. Strictly follow the proportion and select the supporting diluent and curing agent to avoid biting the bottom, wrinkling and other problems

4. Filter the wood paint after mixing.

filter the wood paint after mixing. Because the dust in the air will form small particles after mixing into the wood paint. If it is not filtered and applied directly, particles will appear on the surface of the paint film, and the surface is not smooth enough

therefore, after the wood paint is mixed, it is necessary to use the filter screen bucket to filter out the particle impurities, and then it is best to carry out the construction after standing still for more than ten minutes

5. Differential treatment of remaining paint

after using the water-based wood paint, the remaining paint can be stored in a cool place for further storage in case of need. Nitrocellulose paint and polyurethane paint can only be used once because of the addition of curing agent and diluent, and the remaining paint can only be disposed of

at the same time, after the construction is completed, the waste paint should be properly handled, and the tools should be cleaned in time

what owners need to pay attention to in this step:

it is best to avoid summer when choosing to brush wood paint, because the temperature of air-water genuine stone paint in summer is high, and the air humidity in some areas is high. The surface drying time of paint layer accelerates with the increase of temperature, but the actual drying time is relatively slow; The painter immediately applies another coat of paint after the surface of the paint layer is dry, resulting in the bottom paint layer not completely dry. In rainy days or high humidity weather, the paint layer is easy to turn white. In addition, the temperature in summer is particularly hot, the weather changes greatly, there are many thunderstorms and gales, and the light is particularly strong. These climatic characteristics also have a great impact on the temperature, humidity, light and ventilation, and the distance from the ideal construction environment of wood paint is still a little large, thus affecting the construction of wood paint

the two biggest problems in summer are high temperature and humidity. Don't paint on too hot and rainy days. After the first coat of wood paint is painted, interval more time, and then paint for the second time. This must be watched by the workers, so as to prevent some workers from whitening or peeling due to insufficient interval in order to catch up with the work period
