What is the best method of applying an elastomeric?
Rolling is usually the best method. Consult the Product Datasheet for specifications and recommendations on this. If applying by airless, you should use .021 to .031 tips because this is a fairly heavy-bodied material. When working with a low-texture material, the spray unit must be specifically designed for aggregate coatings. Generally, you can spray on 20 to 30 wet mils by cross coating (a horizontal coating pattern followed by a vertical coating pattern). When rolling, almost invariably a minimum of two coats will be needed to achieve the acquired film thickness. When applying over flat surfaces like poured-in-place concrete, simple spraying works well. When applying over rough surfaces like stucco, spraying would have to be followed by backrolling. Backrolling involves an additional pass with a wet, but not loaded roller, that will force the material into contact with all dips and holes in the surface.
