The colorseal-on-a-reel ensures water tightness in vertical or horizontal structural and abutment joints in virtually any substrate. Colorseal-on-a-reel not only seals out water, it also seals out air, heat, cold, and sound.

Colorseal-on-a-reel replaces traditional liquid sealant and backer rod in the typical “caulk and backer rod” configuration that relies for performance on the difficult-to-achieve ‘hour-glass’ shape.
