    Core tips: 1 Preface Water based wood paint includes three major products: wood decoration paint, furniture paint and floor paint Water based wood paint is only a semi-finished product It can only become a finished product after a construction process, until the film is formed on the substrate and the decorative effect is produced The ideal decorative effect depends not only on the excellent performance of waterborne wood paint itself, but also on the reasonable product supporting construction, excellent construction technology and standard operation under appropriate environmental conditions Good base material treatment, strict construction and control are the guarantee to realize high quality project 2、 Construction workers Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: first, the introduction of water-based wood paint including wood decoration paint, furniture paint and floor paint three products, water-based wood paint, only semi-finished products, must go through a construction process, until the film on the substrate and produce decorative effects, can become finished products The ideal decorative effect depends not only on the excellent performance of waterborne wood paint itself, but also on the reasonable product supporting construction, excellent construction technology and standard operation under appropriate environmental conditions Good base material treatment, strict construction and control are the guarantee to realize high quality project 2、 Construction process: base material treatment - puttying (base material leveling can be avoided) - primer painting - finish painting Notes: 1 Base material treatment: the moisture content of wood material is higher than 12%, and the construction cannot be carried out when the hand touch is wet The wood base material must be clean, flat and free of oil stain, glue and other impurities If there is oil stain, it can be removed with Tianna water 2 Base material treatment before woodworking Construction: seal with universal primer or surface cleaning primer (remove dust and dirt on the surface, especially glue before sealing the primer) Then carry out construction) treatment, and then enter the construction site for woodworking 3 Puttying: if the surface is rough, clear puttying shall be applied for 1-3 times, with an interval of 2-3 hours There is no need to polish and dry the even and even layers Puttying can also be arranged before and after woodworking The putty does not need to be diluted Generally, it should be well scraped and applied after one coat of primer Brush primer: Brush primer 2-3 times every 4-5 hours After each time is dry (depending on the humidity and climate), polish with 800 × sandpaper, and dilute the primer with 10-20% water Brush the top coat: Brush 2-3 times of the top coat, with an interval of 4-5 hours After each time is dry, Polish lightly with more than 800 × sandpaper 4 Before applying the water-based paint to wood, when the oil-based primer has been applied, the paint bottom shall be polished Generally, 360 × sandpaper shall be used for polishing, and the water-based primer can be applied only after the dust is removed, otherwise the adhesion of the paint film will be affected 5 When applying primer for construction, for some rough base materials, 360-400 × sandpaper shall be used to polish the base materials first, and the primer can be applied only after the grinding dust is removed, otherwise the construction effect will be affected For the dust that has entered the wood grain, it can be removed by brush or sucked out by clean towel and cloth with humidity 3、 Common construction scheme: A varnish 1 Base material treatment: dust removal Use 400 × sandpaper to polish the base material For the board and wire with wood grain, Polish along the direction of wood grain to remove surface stains, especially glue 2 Brush the primer for the first time (most of the plates have been painted with oil primer or multi-purpose bottom and bottom cleaning) Add about 15% water to the primer 3 Fill the nail hole: Note: when adjusting the nail hole putty, the color is slightly darker than that of the plate Try it first if you are not sure After the nail hole is polished, it must be cleaned with a brown brush 4 Apply the second coat of primer, and consider whether to apply one or two coats of putty after drying It depends on the depth of wood grain, and there is no need to polish in the middle 5 Brush the primer for the third time, polish the putty with 600 × sandpaper, and dry it with no sandpaper 6 Brush the first finishing coat (mix 15% water, mix well, use 300 mesh filter cloth, leave it for 20 minutes, and clean the surrounding environment) 7 Brush the last finishing coat (800-1000 × sandpaper grinding, remove the surface particles) 8 Treatment of transparent color paint construction base material: first, make one coat of sealing primer primer: scrape one to two coats of transparent putty according to the thickness of wood grain of the board, and polish it smooth Generally, the color mixing in the primer is mainly spray, and make two to three coats of colored primer each time thin spray, spray to the same color as the sample, avoid polishing Topcoat: clean the topcoat twice, if there are particles, it can be lightly ground Special note: for the plates with not very deep color, the high solid bottom is generally used, and the construction is carried out after the nail hole filling process The next process can only be carried out after about 25% water is added, and the next process can only be carried out after the next process is fully dried The dry grinding temperature is 25 ℃, and 3 hours is subject to the production of powder and no sandpaper B Construction process of white paint: 1 Substrate treatment: brush one coat of white primer (mix 10-15% of water to seal the substrate to prevent the color of the plate from coming back If necessary, brush one coat of primer of white paint for sealing) If the primer is not applied first, the self-adjusting putty in the wood eye will bulge easily when encountering water 2 Apply self-adjusting putty twice (the first time is thick and thick, the second time is thin and thin) to level Do not use pig blood ash as the bottom, because pig blood ash itself is afraid of water and will swell when encountering water The method of self-adjusting putty preparation: ① clinker + a small amount of white emulsion + Shuangfei powder or putty powder ② transparent putty + Shuangfei powder + a small amount of water When adjusting putty, it should have hardness and be well polished, which should be controlled on the addition amount of white emulsion The method of applying self-adjusting putty: ① evenly apply the putty to fill in the solid wood seam, and dry grind with 400 × sandpaper after drying The first time, the third time ② Thin batch, not too thick, to prevent cracking The thinner each time, the better 3 After the putty is completely dry, polish it with 600 × sandpaper Add 10-15% water for the first time of painting white primer, avoid adding too much water, polish with 600 × sandpaper after drying completely, and paint the second time of primer The drying time shall be operated according to the actual temperature and must be well dried 4 Spray and brush the first finishing coat (when mixing 10-15% water, make sure to spray the top coat thinly.) after drying out, polish it with 800-1000 × sandpaper 5 Spray the last coat of finish paint (add 15% water and filter with 100 × filter cloth; spray with a cross) the actual effect can be more than one coat of finish paint before the last coat Home of coatings is specialized in
