Paint column: Do this, real stone paint construction power is deep again!

1 True stone paint construction and pollution-resistant performance, is the purchase of real stone paint is one of the most concerned about one of the issues.
, the wall grass-roots treatment
. 1. Materials and tools: 200 sandpaper, oilstone or angle grinder.
2. First of all, the grass to view the surface floating particles, residue removal to ensure that the surface clean, no loose matter, no moisture

.
3. All-round repair treatment is carried out on the small cracks in the surface, sand eyes and impotence.
4. For repair areas, polish with coarse sandpaper to ensure that the texture and large area are consistent after repair, and to clean the floating ash to ensure that the finish layer is firmly integrated with the base.
acceptance criteria: solid surface, no loose matter, no cracks, clean, dry, no moisture, no sand eyes, no empty drum, no mortar, no obvious bumps and other phenomena, no oil pollution, floating ash and other pollutants.
, scrape moisture-proof putty twice
. 1. The use of waterproof putty in the anti-crack layer mortar scraping to find flat, putty must be compatible with anti-cracking mortar, it is best to use the same enterprise's products, otherwise, due to swelling will lead to different sizes of cracks in the real stone paint.
2. Putty should be on-site deployment, stirring well, toothpaste-like, after deployment should be used up once. Dilution ratio, powder: water: 100:20 to 29, that is, each bag of 25 kg of powder plus water 5 to 7.25 kg, after construction at least 12h must prevent rain, hot sunlight and frost. The construction temperature is 5-35 degrees and the relative humidity of the air is 75%.
3. During construction, the putty is evenly applied to the base surface with a smear knife, the thickness of each batch is controlled within 0.8mm, 1-2, and the second channel should be approved only after the first line is completely dry.
4. Putty dry solid after grinding until the surface is free of scratches flat, and remove floating ash, surface flatness deviation should be controlled within 2mm.
5. Only after the putty is dried can the next process be carried out.
acceptance criteria: surface flat, uniform, clean, no scratches, no cracks, yin and yang angle straight, square, no floating ash and other debris.
, roll to apply anti-alkali primer
. 1. After the surface treatment of the grass-roots, should be carefully examined, confirmed to meet the requirements, testing the water content of the grass-roots less than 10%, the grass-roots wall primer construction.
2. The basic back cover before the doors and windows, air-conditioning brackets and other metal parts of the necessary wrap and cover, to be removed after the completion of the overall spraying, to prevent pollution and rust.
3. Before the construction of the grass-roots closed primer, it is necessary to dilute it in strict accordance with the dilution ratio stipulated by the product, and note that the primer should be stirred thoroughly when diluted to ensure uniformity.
paint the primer only after the putty is dry.
5. Brush primer 4-6 hours later into the next process; acceptance criteria: spray uniform, no leakage, no bottom leakage, no flow hanging.
Seventh, sub-grid seam bullet line
according to the requirements of the wall to be divided, divided from the whole monomer around the top down at the same time, to ensure that the corresponding gray seams around the same horizontal line, all vertical gray seams parallel to each other, lead hanging, so that the gray seams horizontal vertical.
the acceptance criteria: the lines are straight vertical, the double parallel lines are wide and narrow consistent, clear and clear.
Thye, brush split seam paint
using split seam paint brush split seam, in order to ensure that the split seam does not appear exposed, the split seam paint brush width can be appropriately wider than the design, to ensure that the split seam paint within the width of the split seam is full.
acceptance criteria: brush paint should be horizontal vertical, wide and narrow consistent, deep and light consistent, the inner grid seam paint full, the effect is clear, not exposed, no skin, no pollution of other parts.
6, sub-sectional seam secondary bounty
by painting the split-block seam paint, the first section seam sewing bullet line has been obscured, in order to let the tape strip straight, the need for a second bullet line only need to pop the split-section seam side line can be.
, paste the sub-grid seam paper
beauty paper paste, with the second section seam bullet line alignment can be.
acceptance criteria: beautiful paper paste solid, tight, straight, tear not damage the grid line, non-stick bad seam paint.
eight, real stone paint spray
. 1. True stone paint should be diluted in strict accordance with the dilution ratio specified by the product, and should be fully stirred when diluted to ensure uniformity.
2. Construction is performed sequentially from top to bottom when spraying.
3. The coating in the construction should be connected to the grid line or window cover, etc., to avoid the color difference at the combination.
4. When different real stone paint construction, should wait for a real stone paint construction completed and table dry before carrying out another color real stone paint construction, construction needs to be another color real stone paint protection to prevent pollution.
. Before use, the real stone paint must be thoroughly stirred, the construction gap should be covered tightly bucket cover, to prevent the coating skin.
. Using spray method construction, before construction must be test sprayed, to determine the use of nozzles, working pressure, spray gun movement speed and other construction factors, to ensure the quality and effect of application.
acceptance criteria: spray uniform, thick and thin consistent, color consistent, particle dot uniform, size in line with the requirements, no bottom, no leakage, no drop and other phenomena, no accumulation at the corner of the yin, do not pollute doors and windows, glass and other parts.
9, true stone paint polishing
true stone paint polishing in the spray waterproof protective film before, need to use ordinary 400-600 matte paper to grind out the dry coating surface of the sand and the sharp angle of the sand grain, increase the beauty of the natural real stone paint surface, while ensuring the complete coverage of the protective film. Force must not be too strong, otherwise, will destroy the paint film, causing the bottom loose, serious will cause poor adhesion, real stone paint off and other undesirable phenomena.
, tear off the split-striped paper
. 1. Before the tape is torn, the tape should be cut off with a paper cutter at the cross-sectional junction, in the direction parallel to the horizontal tape, the vertical tape will be cut off to avoid tearing the tape when the real stone paint falls off.
2. Unmasking time control, unmasking time, the sooner the better, as far as possible to shorten the time, so as not to really stone paint surface skin, debunked.
3. Unmask the direction of the paper, nearly 180 degrees open line.
11, split seam treatment
split seam treatment tape tearing, the gray seam finishing and repair, to ensure that the gray seam straight and wide and narrow consistent, repair, should avoid secondary pollution.
, roll the dust cover face paint
. 1. After the construction of real stone paint, the coating surface is hard and dry, dry on sunny days for more than 24 hours, rainy days should extend the drying time, in order to carry out the construction of cover paint spraying.
2. Mask paint should be diluted in strict accordance with the dilution ratio specified by the product, pay attention to the dilution should be fully stirred to ensure uniformity.
3. Rolling construction should be constructed sequentially from top to bottom.
4. The coating in the construction should be connected in the grid line or window cover, etc., to avoid the color difference at the combination.
5. Spraying and rolling coating can be used for construction.
acceptance criteria: uniform paint, color consistent, no leakage, no hanging, no bottom leakage, no accumulation at the corner of the yin.
stone paint is poor anti-fouling refers to: dust and dirt is easy to deposit, seepage, rain and artificial difficult to remove, fundamentally affect the appearance of the building.
how to solve the problem of anti-fouling of real stone paint? The old saying re-mentions: "three points of products, seven points of construction." True stone paint all performance depends on two aspects: first, the quality of the product itself (the quality of raw materials, emulsion content), and second, the construction process.
the tightness of real stone paint mainly depends on three aspects:
1, the size of the particles of colored sand, fine particles adjusted to make real stone paint denser.
2, emulsion quality and content, the use of excellent water resistance emulsion, and ensure a reasonable content of emulsion.
3, scientific production process.
