How to use the external wall insulation corner net 5

Introduction to thermal insulation and corner protection.

The use of external wall insulation and corner protection, no need to use the ruler board, can be step-by-step construction, can improve the construction efficiency 2-5 times, the original intermediate plasterer can complete the work, after the use of the product junior plasterer can be completed. For example: the original ten months of the project period, after the use of this product, can shorten the construction period of 2-3 months, effectively reduce the construction cost, it is certain to say, as long as it is not man-made strong damage, the corner in normal use, even if it is difficult to destroy a certain impact, the impact resistance of the corner can reach more than 100 kilograms.

In the original construction process, the construction of indoor and outdoor wall corners required highly skilled professionals to carry out the construction, which required high salaries.

The new type of "corner protection for indoor and outdoor walls" can be constructed synchronously with the main project, and can speed up the construction progress, improve the quality of the project, reduce the cost of the project, and reduce the labor intensity of the construction personnel. The product effectively solves the long-term problems of unstraight, uneven, unsightly and easily damaged corners of the wall in building construction.

At the same time, the external wall insulation needs to paste the mesh cloth, in the corner treatment, the construction speed is slow, the impact resistance of the wall corner is poor, because the key parts such as the corner and the window sill, the door are easy to be damaged, and the damaged wall corner is not repaired by professional maintenance personnel, after a long time of weathering, water seepage, resulting in the cracking of the wall.

Where are the thermal insulation corners applied?

Gypsum board wall and insulation system wall corner, window side corner and other yang angle treatment, it can be completely combined with caulk and thermal insulation mortar to form a solid yang angle insulation protection system, no rust, alkali resistance, aging resistance, high strength and anti-wound, effectively ensure the vertical smoothness of the yang angle, the mesh structure on both sides of the corner protection strip, so that the bond is stronger.

2.Thermal insulation and corner protection features.

Thermal insulation and corner protection solve the common quality problems that exist in building construction for a long time, such as the yang angle is not straight, unbeautiful, and the wall corner is easy to be damaged. In the external wall insulation treatment, the construction speed is slow, the impact resistance of the corner is poor, and the wall cracks after a long time of weathering and water seepage. The use of this product will completely solve all the above wall quality problems and difficult problems of project delivery, ensure that there are no cracks in the insulation mortar layer, and the combination of plastic strips and glass fiber mesh sewing, acid and alkali resistance can also improve the level of earthquake resistance, and reduce the best disasters.

3.Insulation and corner protection construction method:

1. Apply the insulation board adhesive on the outside of the wall first.

2. Paste the insulation board, and then smear the mortar layer.

3. Put this product close to the corner of the wall and fix it with caulking paste or stability nails.

4. The mortar is required to be extruded from the hole of the corner protection strip, and then the anti-crack plastering mortar layer is brushed.

During construction, according to the thickness of the external wall insulation layer and the actual situation, the appropriate specifications of thermal insulation corner protection net (or with dripping corner protection strip) should be selected around the yin and yang corners of the exterior wall and the door and window openings, and after the anti-cracking mortar is smeared on the insulation board and the mesh cloth is pasted, the thermal insulation corner protection is closely attached to the yin and yang corners, and the anti-crack mortar is extruded from the hole of the corner protection strip.

Summary. Exterior wall insulation requires yin and yang corner protection.

1. The yin and yang corners of the wall must be straight, in order to ensure that the yin and yang corners of the wall paint must be straight, when doing the yin corners, be sure to play the line, and visually find out the most protruding place of the wall when playing the line, hold down these two points to pop up a black line, and then use the angle aluminum model of the meter to scrape the pop-up line; The yang angle is kept straight, generally scraped with 2 meters of aluminum alloy together, the other side is scraped with a scraper, in order to ensure the durability of the yang angle, white cement and gypsum powder can be used when scraping. 2. Paste wallpaper on the yin and yang corners of the wall When pasting wallpaper, the yin and yang corners of the wall are the most prone to problems. When pasting the corner of the sun, carefully paste the wallpaper on the wall with a scraper, and cross the corner of the convex wall, straighten the folds from top to bottom at the corner of the convex wall with your hands, and then Li Na uses an artist to cut the wallpaper along the vertical line, add glue to paste it, and flatten it with pressure.

When pasting in the dark corner, smooth it from the center of the last wallpaper to the concave wall, scrape up and down with a scraper to make the extended part stick to the wall, and wipe the glue on the scraper clean, and cover the wallpaper. 3. Tile tiles on the yin and yang corners of the wall When pasting tiles, the yin and yang corners of the wall are the most difficult. The more common method is to use the tile itself to brighten the splicing, and the method is often used on the edge of the tile.

1. Cut the metal corner strip to the required length, and apply adhesive plaster at the corner to bond the metal corner strip, or fix it directly at the corner with screws.

2. Paste the metal corner strip along the sunny corner to the caulk, and gently squeeze it to make it firmly bonded. Cover each side with 100mm wide caulk and allow to dry.

3. After the second layer of caulk is dried, gently polish the surface of the caulk with sandpaper.

4. Apply the third layer of caulk about 200mm wide on each side. 1.First, check the verticality of the corner of the wall and the flatness of the wall, and if the error is too large, the protrusion and uneven depression should be removed.

2.To make a special cement slurry: white cement and wood glue to about 3:

Mix and stir in the ratio of 1, add an appropriate amount of old powder and 801 glue, and stir well. 3.Smooth the corners and walls with special cement slurry, and maintain the appropriate thickness of the slurry.

4.The corner protector is close to the corner of the wall, and the slurry overflows from the punching hole; If fastness is to be strengthened, Charbeau recommends fixing it with nails. Then, the cement slurry at the overflow punch is gently smoothed.

5.After a little drying, brush with another layer of professional pulp and smooth it out. 6.

After natural air drying, it generally takes about 48 hours, if it is in the rainy season, it can be appropriately extended, slightly sanded with sandpaper, and then brushed with a layer of putty old powder. 7.Finally, you can choose to brush paint, paint or.
