Over the roof slab an exposed coating of Water Guard 3020N is recommended. Water Guard 3020N is a one component, acrylic co-polymer based flexible waterproofing system ideal for use on cementitious and metal surfaces. The reason for having an exposed coating is that with regular wear and tear it is easy to maintain this coating over the industrial slab from time to time (Please refer to the product data sheet for further information). The application of Water Guard 3020N is recommended in at least 2 coats of application. Both the coats should be applied in opposite right-angled directions. If the first coat is applied as a top to bottom pattern the second coat is to be applied in a left to right pattern.
Once the coating of Water Guard 3020N has properly been applied, flood tests can be carried out to find various spots of leakage. Once a leak point has been identified, it should be rectified accordingly.
Note: for industrial applications, the coating of Water Guard 3020N has been left exposed. The reason being that regular maintenance of the coating can be done easily when exposed.
