Application Techniques： Thoroughly clean the surface to remove dirt, dust, grease, and oil, and let it dry completely. Painting width must be ≥20cm: Most of the construction surfaces are water-absorbing materials. If the coating width is too narrow, rainwater will flow around the waterproof layer and cause re-seepage inside the substrate. Therefore, when repairing cracks, the spray width must be greater than or equal to 20cm (8 inches). Before construction, be sure to accurately locate the leaking point: Most people who have not been in contact with waterproof construction often have a wrong understanding, thinking that the water leakage marks downstairs correspond to the water leakage point upstairs. In fact, we often encounter situations where the leak point is far away from the leak marks during construction. In this case, the construction can generally be extended from the position of the indoor water leakage marks to the surrounding areas. INSTRUCTION FOR GAPS OVER 1/4" (0.6cm) Clean the gaps, free of dust, keep the surface clean and dry. Pour the coating on the crack or leaking point and apply evenly. Cover a layer of Nonwoven Polypropylene Fabric at the crack to enhance the toughness after curing. Apply the coating again until the Nonwoven Polypropylene Fabric is fully covered. Repeat this process again if the gap is larger than 1/4" . Easy Solution for Leak Prevention Easily create a watertight seal with Tapel Liquid Rubber. Apply by brush or pour onto any surface for a durable, flexible barrier against air, water, and moisture. Self-levelling Tapel Waterproof Sealant is self-levelling, ensuring a smooth surface on uneven terrain.
