What is the practice of water cladding ah

The following answers are provided by Jubilee Paint:

Construction process

1, the new grass-roots level thin-layer construction process: the total thickness of the system is 1.2-1.5mm

New grass-roots level thin-layer construction process

2, the new grass-roots level sand stone construction process: the total thickness of the system is 1.2-1.5mm

Sand stone construction process

3, new corrugated stone construction process: the total thickness of the sand stone 1.2-1.5mm

Sand stone construction process

3, the new grass-roots corrugated stone construction process: the total thickness of the system 1.2-1.5mm

Specific steps are as follows:

1, grass-roots level: repair the grass-roots level, remove grass-roots level of dirt, dust and so on.

2, primer: fill the gap, closed wall alkaline, improve the combination of layers, increase the adhesion to the substrate.

3, water-in-water colorful medium paint: imitation stone main color layer, at the same time has the elasticity, to prevent the wall from cracking.

4, water-based colorful coatings: imitation stone modeling layer, you can create almost the same texture as the original stone effect.

5, cover coating: protect the inner coating, with durability and UV resistance.

Days above the party can be constructed.

I, grass-roots treatment:

1, flatness check:

With a 2m ruler, the first check the base surface, will be obvious concave and convex parts of the marked with a colored pen.

2, point patch:

The hollow drum parts need to do cut partition processing, hole or obvious depression with cement mortar for repair, not obvious with putty point patch.

3, sanding:

With a sander, the obvious protruding parts and the repaired parts are sanded to conform to (≤2mm)

4, dust, and cleanup:

With brushes, spatulas, etc., to remove the wall surface adhesion and floating dust. Large area wall rectification, good compartmentalization of pre-treatment. For metal rods sticking out of the wall, they should be de-rusted first, so as not to contaminate the painted surface with rust stains in the future.

5, positioning, popping line:

To drawings or Party A requirements for segregation joints positioning, width of 2.0cm segregation joints, required to use the ink line popping up 1.6cm wide positioning line.

Two, paint primer:

1, brush or roller coating should be used, and strive to evenly spread.

2, the use of cross-rolling method, to ensure that the construction of no omissions, uniform film.

3, paint construction must be carried out by the building from top to bottom.

4, does not meet the technical requirements, repair treatment.

5, primer coating must wait for drying (about 12 hours) before the next process of construction.

Three, paint in the coating

1, in the coating to provide the main color of the final film

2, coating can be sprayed or rolled

3, the use of cross-spraying or cross-rolling method, to ensure uniformity of the film, color consistency

4, paint construction must be carried out by the building from the top to the bottom.

5, does not meet the technical requirements of the repair process.

6, after the first coating, must be in accordance with the specified interval before the second coating.

Four, spraying colorful coatings

1, no need to filter, avoid intense mixing, the main material will be placed in the pressure tank can be sprayed.

2, using the spray method, and strive for uniformity of the main material layer, the thickness is consistent, adjust the strength of the air pressure to control the size of the point type, pay attention to the air pressure in the tank, as far as possible to control the 0.05MPa.

3, a one-time or multi-variable spraying, can be thin spraying a first time, the second cross-cross spraying. Spray gun operation should be maintained at a constant speed, the general nozzle and spraying surface vertical, spraying distance to 30-40cm most appropriate.

4, after spraying need to stay more than 24h, to be completely dry, before spraying cover coat.

5, the requirements: color consistency, no obvious hanging, leakage of spray, through the bottom of the phenomenon. 6, color and compartmentalization of tape paper, every paragraph should be removed immediately.

Five, tape paper removal method

Spraying is completed, every small section should be immediately torn away from the compartmentalization of the adhesive tape, so as to avoid the paint film after drying and solidifying, when taken to destroy the paint film.

When the colorful paint is dry, use a spatula to remove the edges of the compartmentalized line and other irregular residues, so that the edges and corners are complete and straight.

Sixth, painting overlay topcoat

1, spray gun spraying method

2, each spraying surface should try to be completed at once, the construction must be carried out by the building from the top to the bottom, each spraying to the natural division of the seam, yin and Yang corner junction as a boundary, if a larger range of no compartmentalization of the seam, the use of the upper and lower articulation method, avoiding the stubble of paint traces. As far as possible to avoid the appearance of traces of paint stubble.

Precautions for use

1, air pump pressure ≥ 8kg, air pump pressure tank pipe diameter ≥ pressure to the diameter of the spray gun pipe, the spray gun pipe diameter of 8 # - 12 #

2, the pressure tank to the gun's outlet holes, the discharge of the tube should be less than 4 meters

3, the pressure tank air pressure to 0.5-1.5kg (not more than 1.5kg), the pressure tank should be adjusted to 0.5-1.5kg. 1.5kg (not more than 1.5kg)

4, the pressure tank cover must be tightened with a wrench, and debugging to check that there is no air leakage

5, the pressure tank, pipeline, the spray gun should be cleaned up each time the completion of spraying, spraying in the middle of the need to stop the gun to take a break, the spray gun can be immersed in clean water, so as to avoid spraying the mouth of the gun due to the material dry solid and clogging the gun.

Points to note

1, the best two barrels of material equal, can not be stirred hard.

2, discharge air pressure (tank air pressure) and gun pressure to the same (air pressure is too small, the particles can not be opened, the pressure is too large particles scattered, after a one-time spraying prone to craters)

3, go to the gun should be stable, as little as possible to stop the gun, the gun and the base should be perpendicular to the spraying can not be diagonal spraying.

4, a wall division line shall prevail, ditch joints divided into blocks of spraying is good, good block to block protection measures.

5, in case of scaffolding and the wall is too close to the place, pay attention to spraying uniform speed, so as not to produce scaffolding marks.
