There are a few great reasons why applying a flooring adhesive with a paint roller is a good thing. The first, and probably the most obvious, is that you get to apply the flooring adhesive from a standing position. It's no longer necessary to crawl across the floor on your hands and knees when you can stand up and apply using a roller. Another advantage is that your coverage will increase on a per-gallon basis. Roller-applied adhesives typically are applied rather thinly, which extends the coverage by as much as 50% – a real savings on a per-square-foot basis. Yet another advantage to applying adhesive with a roller is that the drying time is much faster than with traditional trowel applications. Being that it is applied in a thin coat, the adhesive flashes off quickly, allowing for flooring installation much faster than with traditional methods.
