1. Clean the Tile Floor before Construction, and Keep the Floor Free of Dirty Water Stains. If the Gap of Tile Is Too Deep, Fill the Gap with Plugging King First. The Product Does Not Need to Be Mixed, and the Cover Is Brushed Immediately. before Construction, Block the Floor Drain to Prevent Glue Leakage. 2. For Large-Area Construction, It Is Recommended That the Wall Surface Should Be Followed by the Ground, the inside and the outside Should Be First, Which Is Convenient for the Construction Personnel to Exit. during Construction, the Colloid Should Be as Thin as Possible (the Film Becomes Dry Faster), it Is Recommended to Brush the Key Positions (Floor Drain at the Edge of the Toilet/Corner Gap) and Other Parts Twice (the Effect Is Better). The Construction Should Be Completed at One Time, Forming a Continuous and Flat Waterproof Membrane on the Base Surface. 3. After Construction, It Is Suggested That the Place Should Be Ventilated. The Colloid Should Not Be Exposed to Water Or Trample before Drying and Curing. The Colloid Should Be Dried after 2 Hours at Room Temperature above 20 ℃ , and the Film Can Be Formed after 5 Hours, the Lower the Temperature, the Slower the Curing Time (the Lower the Temperature in Winter May Affect the Curing Time) Due to the Difference between the Coating Thickness and the Ambient Temperature, the Curing Time Will Be Slightly Different, based on the Actual Construction Curing Time
