Our sealers can be used with rollers, pump sprayers or airless sprayers. Ultimately, it is up to the applicator to decide on the best method of application for the surface. If you are doing a small square footage project, a roller is an inexpensive method of application if you do not have access to a pump sprayer or airless sprayer. If you are planning on sealing a large area, pump sprayers and airless sprayers help you to finish the job quickly.
