How Do You Smooth Out Flex Seal?
Flex Seal sprays out as a thick liquid and dries to a watertight, flexible rubberized coating. For best results, spray Flex Seal about 8-10 inches from the surface, using an even, sweeping motion. If you need to smooth out Flex Seal, you can do so while it is still wet or uncured by using a disposable paintbrush.
Flex Seal should be applied one coat at a time. Allow 24-48 hours for Flex Seal to fully cure before applying additional coats. Here’s to smooth sealing for all your projects!
