One: the basic requirements: flat, strong, dry, clean. The new plaster layer can be applied after at least 14 days of hardening and drying (the base layer is less than 2-5 mm square meters).
2: Material preparation: Add water according to the weight of the material 25-30% (the amount of water can be adjusted according to the base layer and climate), until the mixing is uniform, the mixture should be used within 2 hours.
Three: The amount of bonded polystyrene board is 4-5 kg ​​square meters. According to the flat condition of the wall, the bonding of the polystyrene board is carried out by the whole surface bonding method or the point frame method.
A: Full-surface bonding: Suitable for flat bases with a flatness of less than 5 mm and one square meter. Apply the adhesive to the thermal insulation board with a sawtooth trowel, and then bond the thermal insulation board to the wall from bottom to top. The surface of the board is flat and the seam is tight without gaps.
B: Point frame method bonding: suitable for uneven base layer with unevenness less than 10 mm square meter. Use a plastering knife to evenly apply the adhesive to the edge of the insulation board, and then evenly distribute 6 bonding points on the surface of the board. The thickness of the coating is determined by the flatness of the wall surface. Then stick the board to the wall as described above.
Proportion
The ratio of the bonding mortar to water is about 4:1 (weight ratio)) until it is evenly stirred. Reference dosage: 4~6kg/m2
The state of the base wall
The base wall must be flat, strong, clean and dry. The coating layer and the loose layer of the plaster layer on the surface of the base wall must be removed. The newly painted plaster layer must be dried and hardened before use.
Material construction
Use a plastering knife to wipe the bonding glue onto the insulation board, and then evenly press the insulation board from the bottom to the base wall surface. The board surface should be flat and the seam should be pressed to no gap. Check the flatness with a 2m ruler, and there should be no glue between the joints.
Paste method: Paste paste or paste paste area ≥ 40% of the entire board area.
