1. Before the implementation of PANHOO steel protector self-protecting waterproof coating, the metal roof waterproof base should be properly treated: the metal roof trench should have no clear water, no leakage, unevenness, and should be kept flat, firm and clean. In the case of cracks, the leaking must be leveled first. 2, for PANHOO steel protection treasure self-protection metal roof waterproof system, the pre-treatment of the metal roof of the bottom of the bottom of the gutter, joints, bite needs to be sealed with polyurethane sealant, and then smooth with paint. Make the edge smooth and smooth without water. 3, the metal roof gutter in the water drop section, the same bite, joints are dense, fill. The water intake should not be high. If there is water, the water should be treated and the whole construction work should be carried out. 4. After the waterproof coating is opened, it should be fully stirred and evenly coated with elastic sealing paint. When wet, spread the polyester cloth, then apply the bottom coating in time. After the bottom coating is dry, finally brush the surface to isolate the coating. 5, scraping: according to the design requirements of the waterproof layer with a scraper for scratching, 6. Evenly apply each corner according to the appropriate amount of the bottom layer. Apply a hard brush to the corner several times. After the coating is dry, use a round wooden stick to woven the polyester cloth, and immediately construct the middle layer of steel. The undercoat of the Guardian, waiting for the middle layer to dry, can be used to paint the surface layer PANHOO surface acoustic coating. Tip: The time interval between the layers is determined by the dryness and non-stickiness of each layer of film. When the paint has sedimentation, it should be stirred evenly at any time. When scraping the material for each person, first stir the bottom of the tank a few times to avoid sedimentation. 7. The construction sequence first makes the node additional layer, and then the large area is painted. The coating of the corner and the façade should be brushed many times without any flow or accumulation. 8. The scraping film should be uniform, and there should be no local deposition. It is required to apply a few times of scraping to make no bubbles between the coating and the base layer, and the bonding is strict. 9, each layer of coating must be taken according to the specified amount, can not be too thick or too thin. 10, the best construction temperature should be 5-30 degrees Celsius, when the film construction is not cured, should pay attention to protection, so as not to damage the waterproof layer.
