Uneven and plate seam platforms should first be polished and repaired.layers should be reinforced using non-woven fabric. Firstly, apnon-woven reinforced additional layer before the coating surfac\"criss-cross\" spraying method should be used; each time the wet film thickness should not exceed 1.0mm to maintain uniformity, with no exposed bottom or accumulation of material.After the first coat is dry, the second can be applied, with thamount used for the third coating should be controlled accordinted after inspection, the membranes can be laid.Packaging, Transportation, and StorageThe product should be stored in a dry, well-ventilated place away from direct sunlight at a temperature between This product has a storage period of one year under normal transportation and storage conditions from the date
09Application PointsBase surface treatment: The base surface should be solid and flat without dust and oil stains. Any uneven areas or misaligned joints should be ground smooth and repairedtailed joints should be applied a layer of coating. Secondly, the reinforcing additional layer of non-woven fabric should be placed before the coating surface dries. Finally, another layer of coating should be applied to tApplication of large-area coating: Mechanical spraying is highly recommended (roller application is also acceptable). Cross spraying should be adopted with the wet filmSubsequent coating: Once the first coating has dried, apply the second one. After the second coating has Proceed to the next step only after the coating has dried and passed inspection.Product OverviewProduct ApplicationsProduct FeaturesThe product is a single-component waterproof coating that is mamodified with polymer rubber latex and various special functional additives.
