Base inspection
After the base layer is plastered for about 15 days, the plaster base surface is surveyed and leveled. The verticality and flatness should not be greater than 2mm; the cracking and emptying area, reserved holes and scaffolding holes and loading openings require the use of cement and mortar with early strength agent to repair the caulking holes. When plastering, it should be smeared and required to be smoothed; the wall moisture content should not exceed 8%, and the pH value should be less than 10.
Base surface treatment
1) Clean the surface of the floating ash, garbage, oil, etc. with a gray knife; brush the plastic wall of the wall with an epoxy primer and fill it with polymer anti-cracking mortar, which will be obviously sunken. Use special putty points to fill up; flatten the raised parts, the flatness requirement is less than 1.5mm.
Friendly high-end finish
2) Strengthen the treatment with the fiberglass cloth. The polymer is cracked with a crack-proof mortar, embedded in an alkali-resistant glass fiber mesh, and then coated with a polymer crack-resistant mortar on an alkali-resistant glass fiber mesh, and the width is required to be larger than the edge of the alkali-resistant glass fiber mesh by 2 cm.
Flat putty construction
1) The first flat-bottomed putty construction, with a special scraper to scrape from top to bottom and from left to right, the scraper should be stable during the construction process, and once in place, there should be no pause in the middle to prevent leaving traces. Its purpose is to level.
2) Grinding: Grinding with 150#~220# sandpaper (Note: the first two putty), after each putty is finished for 4h, the dried and solidified putty is polished to eliminate the uneven parts.
3) The second flat-bottomed putty construction, with a special batch of knives full batch, pay attention to the knife can not have joints, knives, full batch must be in place once, the requirements must be flat.
4) After drying, polish with the above (2), and then sand with 200#~300#. Special attention: (a) The surrounding of the grinding hole must be leveled before the next process can be carried out. (b) The interval between the two constructions should not be less than 4 hours, and pay attention to the water conservation in the middle.
Wall primer construction
The material has strong binding force, further integrates the plaster layer and the putty bottom, improves the waterproof performance, neutralizes and isolates the free base, and prevents the efflorescence. Construction requirements: use a short wool roller to roll in place, requiring no sag, no leakage coating.
Separate seam setting
The positioning, width, horizontal and vertical direction and overall distribution of the joints are carried out according to the engineering design requirements; after the joints are positioned, the lines can be laid to ensure the width and uniformity of the joints. (2) Brush the separation joint, first use the epoxy seal wall primer to paint the separation seam position, and then use the black high-gloss fluorocarbon paint to paint the separation joint.
Elastic coating construction
The use of high-performance elastic paint of the same color makes the overall structure three-dimensional effect, can effectively prevent wall cracking, and can be combined with fluorocarbon metal paint to produce excellent adhesion. Construction method: Rolling with fine-drawn roller, the pattern is required to be consistent. [1]
Elastic fluorocarbon middle layer paint construction
It has good adhesion, effectively integrates with the bottom layer, excellent coverage, fills the small pinholes in the base layer, improves the waterproof performance, forms a good combination with the back top paint, and plays the role of the upper and lower sides, showing the color of the building. . Construction method: Mix the middle layer paint base, curing agent and thinner in proportion, roll it in place with short wool roller, and require no sag and no leak coating.
Elastic fluorocarbon metal paint construction
Complete protection of the coating system, excellent weather resistance, and metallic luster effect of the haflon fluorocarbon metal paint. Construction method: Mix the topcoat base, curing agent and thinner in proportion, first mature for 30min, first spray the base dust, then apply from left to right and top to bottom, and evenly to prevent thickness and inconsistency. In order to avoid the occurrence of undesirable phenomena such as flowering and sag.
Lacquer construction
Complete protection of the coating system, excellent weather resistance, excellent water resistance, great surface tension, and good self-cleaning performance. Construction method: Mix the topcoat base, curing agent and thinner in proportion, first mature for 30min, first spray the base dust, then apply from left to right and top to bottom, and evenly to prevent thickness and inconsistency. In order to avoid the occurrence of undesirable phenomena such as flowering and sag.
Related Matters
1) The humidity is below 85%, and the temperature is 5~40°C. If rain, snow, fog, frost, strong wind or relative humidity is above 85%, it is not allowed to be constructed;
2) After grinding, rinse the surface with clean water and wait until the water is dry before spraying.
3) The paint film can be completely cured after drying for about 7 days. At this time, it is recommended not to use it in advance;
4) It is necessary to stir the components evenly as required, and use them after 30 minutes of aging;
5) The configured materials should be used up within the specified time. If the materials exceed the time, the materials are not allowed to be used again;
6) It is necessary to use the special accessory materials of this product, and it is strictly forbidden to use other commercially available accessories.
Welded Wire Mesh
It is widely used as machine protecting mesh, garden or residential fence and livestock cage in industrial or agricultural area. In addition, according to different flexibility, welded wire mesh can be divided into 2 types: welded mesh roll and welded Mesh Panel. The former has better flexibility.
