1, main construction technology
(1) varnish construction technology:
Cleaning the wood surface → Sandpaper grinding → Powder spreading → Sandpaper grinding → First putty scraping, Sandpaper grinding → Second putty scraping, Fine sandpaper grinding → Paint painting → First varnish painting → Color matching, putty filling and fine sandpaper grinding → Second varnish painting and fine sandpaper grinding → Third varnish painting, waxing and water sandpaper grinding.
(2) Construction technology of mixed color paint:
First, clean up the dust on the surface of the base, repair the base → smooth it with sandpaper → draw scars → render putty → apply drying oil → blow putty for the first time → polish → apply primer → dry primer → apply topcoat → repair putty → polish topcoat for the third time → apply coating for the second time → polish topcoat for the third time → polish and wax.
2. Key points of construction
Code for construction of oil cleaning and scrubbing
Polishing the base is an important process of painting varnish. First of all, it is necessary to remove dust, oil and other impurities from the wood surface.
Lubricating oil powder is also an important process of varnish painting. During construction, cotton silk is dipped in oil powder and coated on the wood surface, rubbed back and forth by hand, and the oil powder is rubbed into the wood eye.
When brushing clean oil, you should hold the oil brush easily and naturally, and use your fingers gently, so as not to loosen or drop the brush when moving.
When painting, it should be carried out according to the requirements of dipping more times, dipping less oil every time, diligent operation and smooth brushing, and the construction should be carried out according to the operation methods of first up and then down, first difficult and then easy, first left and then right, first inside and then outside, and horizontal and vertical brushing.
Code for construction of mixed oil on wooden surface
In addition to cleaning up the sundries at the grass-roots level, the grass-roots level should also fill in local putty and polish it with sandpaper along the wood grain.
Before painting the top coat, seal the knots and wood resin with lacquer flake (shellac paint). Drying oil or berth clearing should be applied at the grass-roots level, and drying oil layer should be evenly applied to all parts, without brush leakage.
After the priming oil is completely dried, scrape the putty for the first time, polish it with manual sandpaper after drying, and then fill in the high-strength putty. Putty shall be based on not picking silk. When the surface coating is applied, it should be polished with fine sandpaper first.
3. Preventive measures
(1) The base treatment shall be constructed as required to ensure that the surface coating will not fail.
(2) Clean up the surrounding environment to prevent dust from flying.
(3) Because the paint has certain toxicity and strong stimulation to respiratory tract, attention must be paid to ventilation during construction.
Diamond paint is one of real stone paint, real stone paint, imitation stone paint and imitation stone paint. It is a kind of paint that is attached to its surface or mixed with a kind of "artificial diamond particles" during construction. "Diamond Paint" and "Diamond Paint" are the brand names of this paint. This kind of paint and lacquer will produce the reflective effect of inlaid diamonds under light.
In addition to the effects of ordinary diamond paint and real imitation stone paint, its biggest feature is that it increases the reflective effect of diamonds embedded in it, which makes it more beautiful, and increases the lighting warning and sign effect of road traffic and outdoor use, as well as the beautiful and luxurious effect of indoor and outdoor use.
Diamond paint and diamond paint are trade names. The patent name of the coating is "multi-angle reflective coating and its preparation method". It is a China patent exclusively applied by Hainan Guotai Decoration Building Materials Research Institute in the middle section of Renmin Road, Huxian County, Shaanxi Province. The application number is "2009 1002 1056.4".
