Application and Reinforcement
VersEseal is applied using brush, roller, or airless spray equipment, and reinforced with geo fabric where needed for added strength. Typical use includes sealing floor-to-wall joints, cracks, and penetrations in water tanks or ponds. For potable water systems, allow 7 days of curing and discard the first two rinses.
General application steps:
- Prepare the surface (clean and dry)
- Repair or reinforce joins and damaged areas
- Apply VersEseal Rapid Build
- Allow appropriate curing before use
Always refer to our technical data sheets and application guides for specific project requirements.
