Crocodile paint small class . . . Construction guide for imitation limestone coatings.

Imitation limestone coating because of its special texture, can imitate the natural stone effect, and the cost is moderate, in the past two years has gradually become a popular choice for building exterior paint. Natural atmosphere appearance, exquisite patterns, can fully display the texture and artistry of stone, highlighting the quality of the building facade, so it is particularly suitable for high-end residential exterior decoration selection.
Compared with other exterior coatings, imitation limestone coating construction process is more complex, is the use of medium coating, effect coating and cover layer composite way to complete, and need to use special construction tools, the following together to learn under the
1, environmental protection measures
before the construction, first check the surrounding environment, and make appropriate protective measures to cover the window sill, door edge and a place that may be contaminated
II, grass-roots treatment
1, empty drum, layered substation needs to be first eradicated, and then with the outer wall putty to fill the depression, and maintenance for 5 to 7 days.
2, if the original wall moldy condition, first with the old wall treatment agent rolled over, and then with putty to fill the depression, and then follow-up maintenance.
3, if there is floating ash, oil and loose material on the wall, first rinse and clean.
Three, grass-roots approval
1, in the treated base surface with the external wall water-resistant anti-cracking putty batch scraping 1 to 3 times (depending on the grass-roots flatness), each time putty should not be too thick (within 1.5mm), to the wall leveling for the purpose.
2, tiles, mosaic walls, please use the old grass dedicated refurbishment putty.
3, use sandpaper to polish the putty surface.
4, putty grinding after the removal of floating ash, summer maintenance 5 to 7 days, winter correspondingly extended maintenance time, so that the grass-roots moisture content of <10%, PH value of <10.
, primer
1, with wool rollers or spray gun evenly applied primer 1 time. (Do not leak to provide the necessary alkali resistance, water resistance and adhesion)
2, 21 to 25 degrees C of temperature conditions, the primer after completion, need to dry for 6 hours. (When the temperature is low, the drying time should be extended, be sure to wait until the paint is dry)
3, theoretically, the amount of coating should be controlled in the range of 0.12 to 0.15 kg/m2.
, separation planning
1, with ink line bullet line separation.
2, paint the lines.
3, line paint thoroughly dried, paste the textured paper.
, batch scraping imitation limestone coating main material
1, with stainless steel batch knife even batch scraping imitation limestone main material 2 times.
temperature conditions of 2, 21 to 25 degrees Celsius, each construction interval of more than 4 hours.
temperatures of 3, 21 and 25 degrees Celsius, the sanding process needs to be dried for more than 24 hours after completion.
4, in theory, the amount of coating should be controlled in the range of 1.5 to 2.5 kg/m2. (Depending on the difference between grass leveling, surface effect and water absorption rate)
5, batch scraping the second time the main material, ensure flatness, avoid pores and knife marks.
, polished
sanded with 240 sandpaper to smooth the surface. (Avoid traces of sand)
8, imitation limestone paint spray point, flowering
1, spray point: the use of a special atomized spray gun, spray imitation limestone dot paint.
2, spray large color point: the use of special spray, spray imitation limestone color dot paint.
3, stained flowers: use sponge to take a small amount of imitation limestone color dot paint, beat on the base surface.
4, shaped: use special tool points to draw special-shaped textures.
nine, polishing
using a blade to remove the raised color points and spots, etc. , and then with 800 sandpaper polish, so that the surface smooth and smooth.
10, cover paint
1, with paint gun or wool roller evenly applied mask paint 1 to 2 times. Pay attention to the brush evenly in place, do not leak, so as not to affect the color and durability.
temperatures of 2, 21 and 25 degrees Celsius, each brush needs to be separated by 4 hours.
3, in theory, the amount of coating should be controlled in the range of 0.10 to 0.15 kg/m2.
temperature conditions of
21 to 25 degrees C, it takes about 7 days for the coating to become a complete film.
12, construction precautions,
should be strictly controlled according to the construction method, not arbitrarily diluted.
2, to ensure that the construction temperature >5 degrees C, the grass water content of ≤10%, air humidity ≤85% of the conditions can be expected to be constructed. Do not work in extreme weather.
3, imitation limestone paint should be properly stored to avoid exposure, freezing.
4, after the opening of the paint as far as possible a one-time use.
