How thick is the mortar before Profile Pvc is hung

External wall insulation is generally divided into two types: brick exterior wall and paint exterior wall. If it is a paint exterior wall and the thickness of the external insulation layer is less than or equal to 3 cm, Profile Pvc can be omitted. In addition, Profile Pvc must be hung in any case Below, we summarize the requirements for laying Profile Pvc in anti-cracking mortar.

1. For the first floor of the building, door and window openings, decorative seams, corners, etc., an additional layer of drywall tape should be laid, and then a layer of anti-cracking mortar should be applied.

2. The overlap length of ordinary drywall tape should not be less than 100mm, and the reinforced corner vinyl is only connected without overlap.

3. The width of each side of the corner vinyl at the corners should not be less than 20mm.

4. The Profile Pvc around the door and window openings should be turned out of the wall by 100mm, and a layer of 400mm×30mm Profile Pvc should be laid at the four corners along the 45° direction.

Currently, the joint corner used in external wall insulation is divided into internal wall insulation Profile Pvc and Profile Pvc. The inner wall insulation joint corner is made of medium alkali or Profile Pvc as the base material and then coated with modified acrylic copolymer liquid. The Profile Pvc is made of medium alkali or alkali-free Glass Fiber yarn as the raw material, woven into Profile Pvc as the base material, and then coated with acrylic copolymer liquid and dried to form a new type of alkali-resistant product.
