Now winter is coming again, and many friends are lamenting the difference between the experience of good exterior wall insulation and poor exterior wall insulation. In this issue, the exterior wall insulation manufacturer Shandong Bangyuan Information Building Materials Co., Ltd. will teach you how to do exterior wall insulation.
Modern buildings generally have insulation layers on the exterior walls to provide winter and summer insulation, making occupants more comfortable. So how to do exterior wall insulation? I believe many friends are not very clear about the method. The editor will introduce it to you immediately, hoping to be helpful to everyone.
1、 Grassroots cleaning
The substrate plays a decisive role in the adhesion of the insulation board. First, conduct a painting base layer test, and the bonding strength should reach 0.45MPA, with a moisture content of less than 10%.
2、 Mixing of bonding mortar
Mix the adhesive plaster mortar with water in a weight ratio of 4:1 and mix evenly. After standing for 5 minutes, mix the adhesive mortar again and start the painting work.
3、 Laying of insulation board
After the painting is completed, start laying the benzene board. Firstly, snap the horizontal line, install the aluminum bracket underneath, and then stick the horizontal layout board in sequence. Note that the minimum length of the benzene board should not be less than 200mm, and the gap should not exceed 1.5mm.
4、 Adhesive of insulation board
Firstly, use a square tooth trowel to scrape, and then pull out the plaster strip, which is about 5cm wide. The application area is larger than the entire board area. Do not use hand tapping when pasting, and use tools to tap and press it onto the wall. There should be no adhesive left on the four sides of the benzene board to ensure flatness, and the joints should be as small as possible.
5、 Grinding
After laying the benzene board, let it stand for one day and start polishing work. Use a polishing plate to polish the unevenness, and then use a brush to clean the base surface.
6、 Reinforcement layer construction
After drying and cleaning the benzene board, start construction. First, apply a full batch of primer treatment, and then apply the grid cloth into the mortar. If the color of the grid cloth is not visible, use a scraper to smooth the surface. After drying, proceed with the construction of the decorative layer. After the final setting of the mortar, the surface should be watered and cured to prevent the occurrence of cracks due to surface water loss. Start polishing and leveling after an interval of 6-8 hours.

Construction process and precautions of adhesive powder polystyrene particles

Rubber powder polystyrene particle insulation mortar is composed of rubber powder and polystyrene particles. The two materials are packaged in separate bags and mixed with water in proportion (rubber powder 1:2). The material should be used up within 4 hours after mixing.

Characteristics and construction points of polymer bonded mortar

Many customers do not have a special understanding of the characteristics and construction points of polymer bonded mortar. In this issue, Shandong polymer bonded mortar manufacturer will come to chat with you about the characteristics of our products.

What are the main properties of graphite polystyrene board?

Graphite polystyrene board insulation: Graphite polystyrene board EPS polystyrene board mechanism rock wool mortar composite board. Hydrophobic rock wool board is a thermal insulation layer material, which is connected and fixed to the base wall using adhesive and nail bonding technology. It is a Class A non combustible building energy-saving insulation system composed of a plastering layer composed of plastering adhesive and reinforced glass fiber mesh cloth, as well as a decorative mortar facing layer or coating.

The main properties of graphite polystyrene board

Graphite polystyrene board has the same effect and lower cost. The outstanding insulation ability of the insulation board is particularly evident at low density. It is more cost-effective than using conventional EPS insulation boards. High cost-effectiveness, compared to other fire-resistant insulation systems, it is more cost-effective when achieving the same effect.

System characteristics and application scope of external wall insulation board

The external wall insulation board can be used separately for wall insulation using mechanical anchoring method, or can be used for external wall insulation by combining with other insulation materials.

Key points for construction of external wall insulation materials in winter

Shandong Bangyuan New Building Materials Co., Ltd. has found that with the recent cooling of the climate and the decreasing temperature, the construction of external wall insulation projects is facing greater challenges.
