Need some tips on waterproofing? You've come to the right place.Water repellent coatings can be brushed, rolled, or sprayed on, depending on the size of the surface to be treated. For either water- or solvent-based coating, you will definitely need a paintbrush for painting around the edges (called cutting-in). If you're rolling the coating on, use a synthetic roller cover (use a long-napped one for rough surfaces) and a roller pan. Spraying requires low-pressure (20 psi) spray equipment with a stainless-steel, fan-tip nozzle. You will also need plastic dropcloths to protect adjacent surfaces and landscaping. Be sure to wear eye protection and rubber gloves when applying the product.
