Most of the contractors installing elastomeric acrylics, thermoplastic rubber and high silicone coatings will use airless spray equipment such as the Graco 833 Roof Rig. Smaller pumps may be suitable for spraying roof coatings short distances in warm weather. With high solids silicone, spray application can be rather demanding. A larger Graco 933 is typically associated with those materials. It is also possible to brush apply repairs and to use rollers to apply coatings on small projects. In most cases, we will be able to recommend brands or specific vendors that can meet your needs.
