💡 How does moisture cure sealant perform in active construction seams?
This stuff stays squishy and locks out water without requiring extra primer. It is a handy fix for tradespeople dealing with shifting wall seams and concrete panel gaps. Follow these tips to get the job done right.
- Match the medium modulus grade that matches your expected panel movement rates
- Trim the cartridge tip to match the actual gap width before you start laying down a bead
- Work the rubbery paste straight into the joint while it is still fresh and tack free
- Wipe down guns and gloves with mineral spirits before the chemical reaction sets solid
