Latex paint, wood paint, rust-proof paint construction process

Paint is the general called wood paint and latex paint, wood paint is divided into polyester paint and nitro paint two kinds. Polyester paint construction requirements are high, the ratio is strictly complex, a single time into the film after the hand feel good, but after damage is not easy to repair, yellowing performance is unstable, with latex paint at the same time construction may smoke yellow latex paint. Nitro paint is simple and easy to construct, easy to repair after damage, good performance of yellowing resistance, but a single time into the film thin, to reach a certain number of times after the feel

Latex paint construction process
1, the main construction process
First: clean the grass→ fill putty, local scrape putty, grind flat→ Then: the first time full scraping putty, grinding→ All over the scrape putty, grind flat → and then: brush seal the primer →smear the first paint→ make up the putty, grind flat →swep the second paint→ and finally: polish live.
2, construction points
(1) grass-roots treatment is to ensure the quality of the construction of the key link, which ensures that the wall is completely dry is the most basic conditions, should generally be placed for more than 10 days.
(the walls must be flat and scrape the putty at least twice to meet the standard requirements.) )
(2) latex paint coating method can be used hand brush, roll coating and spraying. Brushing should be done continuously and quickly, once.
(3) brush latex paint should be uniform, there can be no leakage brush, flow attachment and other phenomena. Brush it again and polish it again. It should generally be more than twice.
3, construction precautions
(1) putty should be matched with paint performance, solid and solid, not powdered, peeling, cracks. Use water-resistant putty in damp places such as toilets.
(2) coating liquid to be fully stirred, the viscosity is too large to be appropriate without, the viscosity is small can be added thickener.
(3) construction temperature is higher than 10 degrees Celsius, indoor can not have a lot of dust, it is best to avoid rainy days.
wood paint construction process
1, wood paint construction process
(1) varnish construction process
st step: clean wood surface →scrub paper polishing
second step: polishing powder →shaving sanding paper→ scraping the first putty, sand paper polishing → full scrape second Throughout the third step of putty: fine sandpaper polishing →painting oil color→ brushing first varnish→ spelling color, patching putty, fine sand paper polishing→ brushing second varnish, fine sand paper polishing→ brushing third varnish, polishing→ water sanding paper polishing, waxing, polishing.
(2) Mixed paint construction process
st step: clean the grass surface dust, repair the grass →smealing with matte paper→ sections of scars paint tablets →styping bottom scraping putty→ dry oil
second step: the first full scrape putty→ →Passing the underlying paint→ the bottom coating dry hard →passing surface layer→ patching putty for repair→ polishing wipe the third time the paint brushing the second coating →sweed→ the third finish → polishing waxing wax.
2, wood paint construction specification
(1) oil painting construction specification
1: grinding the grass is an important process of painting varnish, should first of all the wood surface dust, oil and other impurities removed clean.
2: Oil powder is also an important process of varnish painting, the construction of cotton wire oil powder applied to the surface of the wood, rub back and forth with your hands, the oil powder into the eyes of the wood.
3: When brushing oil, hand oil brush to be easy and natural, fingers gently force, to move without loose, do not drop the brush.
4: Brushing should be in accordance with the secondary more, each time less oil, operation time, the requirements of the brush, in accordance with the first up and down, first difficult then easy, first left and then right, first inside and outside the order and horizontal brush vertical operation method construction.
(2) wood surface mixed oil construction specification
1: grass-roots treatment, in addition to cleaning up the grass-roots debris, should also be partial putty embedding, sandpaper should be polished along the wood grain.
2: Before painting the surface layer, apply lacquer (worm paint) to the scarring area with a large color difference and wood fat. Should be applied to the grass dry oil or clear berthing, brush dry oil layer to all parts evenly brushed through, can not leak brush.
3: After the bottom oil is dry, scrape the first putty, dry after sandpaper polishing, and then make up high-strength putty, putty to pick the wire does not fall. When applying surface paint, polish it with fine sandpaper first.
3, wood paint construction precautions
(1) grass-roots treatment should be in accordance with the requirements of construction, to ensure that surface paint painting will not fail.
(2) to clean up the surrounding environment, to prevent dust.
(3) because paint has a certain toxicity, the respiratory tract has a strong stimulating effect, construction must pay attention to do a good job of ventilation.
4, paint construction acceptance
(1) feel smooth, grain-free.
(2) paint surface saturation.
(3) gloss is suitable, (cleansing, high transparency).
(4) no pendants, brush marks.
(5) is non-polluting to other types of work.
(6) varnish grass is pollution-free.
(7) mixed oil base flat, smooth, unstoppable feel.
(8) permeable color paint construction color, depth and uniform.
Rust-proof paint construction process
1, construction steps
construction process: grass-roots clean-up →paint paint coating→ inspection and acceptance
2, base surface cleaning
1: construction steel structure engineering paint coating should be carried out after the steel structure installation and acceptance.
2: Before painting, the rust, welding splashes, oil, dust and other debris that need to be coated should be cleaned up.
3, inspection and acceptance
1: surface coating construction and construction, should be coated work to protect against flying dust and other debris.
2: after coating treatment inspection, should be the color of the coating consistent color bright, no wrinkled skin, no mole.
3: The thickness of the coated paint film is determined, the thickness of the paint film is determined by the contact-type paint film thickness meter, and the thickness of the paint film thickness meter is generally measured by 3 points.
4, rust-proof paint construction precautions
(1) pay attention to buy that kind of environmental protection paint, preferably has been diluted, open directly can be used, brush paint can not be too impatient, should have a sequence of slow brushing, to prevent bubbles.
(2) is generally brush 3 times, the first brush after slowly drying, and then brush again, then dry, and then brush again to dry it.
(3) Do not paint on rainy days.
(4) brush when you must slowly brush, look at the brush where there are no bubbles, if there are bubbles immediately broken.
(5) brush after brushing again waiting to dry, immediately clean with water, soaked in water.
(6) masks, glasses must be worn, the former can reduce inhalation of harmful gases, the latter to prevent paint from dripping into the eyes. Single-story plasterboard ceiling for kitchen, bathroom, balcony, basement area.
