sandpaper polish to remove the light, wax and polish Construction Technology (1) base treatment before oil cleaning and painting: grinding base is an important process for painting varnish First, clean the dust, oil and other impurities on the surface of wood, and sink the nail cap into the wood 1 mm as required When sanding the sandpaper, wrap the sandpaper around the short wood square and pad it for grinding The line angle and large surface shall be ground and polished, and the cloth surface shall be cleaned with damp cloth or cotton wire (2) Use a knife or scraper to scrape the oil putty or transparent putty into the nail hole, joint and other places When scraping, it is required to wipe horizontally and vertically, scrape and clean After drying out, use sandpaper to gently Polish along the wood grain, and wipe with a damp cloth or cotton thread (3) Construction specification for oil cleaning and painting: when painting oil cleaning, construction shall be carried out in accordance with the sequence of first up and then down, first difficult and then easy, first left and then right, first inside and then outside, and the operation method of horizontal brushing firmness and smoothness Paint construction process (4) when the first coat of varnish is applied, a certain amount of thinner shall be added to dilute the paint liquid, so as to facilitate the quick drying of the paint film (5) During the operation, the paint shall be applied along the wood grain, and the paint film shall be even without missing or falling After the clear oil is completely dry and hardened, it shall be polished with sandpaper When polishing, it is required to polish all the brightness on the paint film to increase the bonding degree with the subsequent coating After grinding, wipe it with damp cloth or cotton thread (6) After the first coat of varnish is applied, the finish shall be cleaned and repaired For obvious unevenness of the paint surface, the same oil putty with the same color as the paint surface can be used for repair If the knots and black spots on the wood surface are inconsistent with the large paint surface, the oil color of the required color shall be prepared and covered to ensure that there is no big color difference in the finish When brushing the varnish for the second time, it should be fully brushed, and the paint film can be slightly thicker During the operation, it should be brushed several times in the horizontal and vertical directions to make it bright and uniform If there is a phenomenon of falling, it should be smoothed with the brush immediately according to the original direction when it is not dry After the second coat of paint is completely dry, polish and wipe it according to the treatment method of the first coat When the third coat is applied to the next coat, it is different from the general paint works When polishing, first dip the abrasive paper in soapy water for grinding Start with 320 water sandpaper and finish with 600 water sandpaper When grinding, the force shall be even and the whole paint film shall be ground Then dip the sand wax (polishing paste) on the soft cloth and rub it repeatedly on the surface of the paint film Soft cloth should not be too much wax liquid, rubbing action to be fast When the surface is very smooth and flat, polish the wax, dip cotton in the wax, and wipe a thin layer on the surface of the paint film Paint Construction Technology (7) environmental requirements for varnish painting: when the wood surface is painted with varnish, the requirements for the environment are high When the environment cannot meet the required standards, the quality of the project will be affected The painting site shall be clean and free of dust Before painting, it shall be thoroughly cleaned During painting, air circulation shall be strengthened During operation, the ground shall be frequently sprinkled with clean water, and cross operation with dust producing work is not allowed Therefore, the application of varnish should be in the final stage of home decoration works The painting shall be carried out in a slightly dry climate, and the temperature must be above 5 ° C before construction, so as to ensure the normal dry fixation of the paint film, shorten the construction period and improve the quality of the paint film Construction technology of
