BASF recently launched MasterSeal SL 100, designed to help expedite construction project schedules and keep horizontal joints weathertight, even in the most demanding conditions.
Its hybrid technology permits application to freshly placed (green) concrete as soon as 24 hours after forms are removed, compared with the 21 days recommended for most sealants. Earlier access to jobsites allows contractors to save on labor costs. The sealant can also be placed on damp concrete, helping minimize the impact of rain on project schedules.
MasterSeal SL 100 adheres to multiple substrates such as concrete, metal and stone. Recommended uses include plaza decks, parking structures, balconies, industrial floors, driveways and garages, sidewalks and numerous other horizontal joint applications.
MasterSeal SL 100 has a skin time of 5-45 minutes, depending on weather conditions. This feature shortens project schedules as it requires less time to dry and reduces accumulation of dust and debris. The strong UV resistance results in a weathertight seal that retains its color over time. It can also be painted once cured, allowing for future flexibility.
