FAQ: Solving Common Challenges
Q: What happens if Component B is overused?
A: Excess Component B degrades membrane properties; stick to the 100:6 ratio.
Q: Can IMPERMAX COLD POLYUREA withstand rain during curing?
A: Yes! It develops rain resistance within 1 hour (ideal for unpredictable weather).
Q: How to clean tools post-application?
A: Use Rayston Solvent before curing; hardened residue requires mechanical removal.
