What should polyurethane be used for roof waterproof and thermal insulation? In addition to the basic treatment, what are the construction steps for the entire roof waterproof and thermal insulation project? How does Hightop Machinery introduce?
Polyurethane is used for roof waterproof and heat preservation. Make the roof basically flat, without floating dust and oil!
Polyurethane is used to spray rigid polyurethane foam for roof waterproof and thermal insulation. Special equipment sprays rigid polyurethane foam plastic on the base surface to form a dense foam material immediately. According to the thickness of the insulation layer, a construction work surface can be sprayed several times, and the construction work surface of the same day must be sprayed continuously on the same day.
Polyurethane is used for roofing waterproof and thermal insulation to apply surface glue. Apply surface glue on the surface of the polyurethane foam in batches. During construction, make the surface smooth and maintain a constant humidity.
Polyurethane is used for roof waterproofing and insulation and mesh cloth must be added. While the glue is not dry, cover the glass fiber mesh on the surface of the glue, and press the mesh into the glue with a knife.
Polyurethane is used for roof waterproof and thermal insulation to be coated with waterproof and anti-crack glue. After the surface of the previous layer of glue is dry, apply the glue again, the thickness of the two times is not less than 2mm, to ensure the firmness of the exterior layer.
The above briefly describes the relevant steps of polyurethane used in roof waterproof and thermal insulation. For more information on polyurethane, please continue to pay attention to Hightop Machinery.
