Expert Verdict Reviewed by the SuperArbor Pro Desk

ASTM C 920 listing makes 4300 a solid choice for expansion and control joints where movement capability matters. Tool the bead within the working time and size joints per standard sealant practice. On damp substrates, expect possible cloudiness in the cured clear sealant, so test in a hidden area where appearance is critical.

Use in a ventilated area and wear eye protection; follow the safety data sheet when applying chemically curing sealants.
