Made in the USA! How to Use:Once you've applied drywall tape manually, using a "banjo" taper, or employing an automatic taper, the corner roller becomes essential. Its purpose is to effectively embed the tape within interior corner seams, while eliminating excess compound or air pockets.Begin the process from the midpoint of the tape's span, then roll consistently back and forth (or up and down) toward the corners. Gradually widen your passes during this motion.Employ substantial pressure to guarantee a securely bedded tape.The outcome should reveal a precise, crisp 90-degree angle in the tape, featuring smooth and flat tape flanges on the two opposing walls. With this, your interior corner is primed for coating and final touches.Remember to clean the corner roller before the compound sets to prevent accumulation within the rollers.Prior to and after each use, make sure to apply 3-in-1 machine oil to lubricate the rollers.
