Expert Verdict — Reviewed by the SuperArbor Pro Desk
On exterior trim and skylight details, a 100% silicone sealant like this gives the best long-term flexibility because it does not rely on solvent evaporation. Tool the bead immediately after application and confirm the substrate is clean and dry for best adhesion. Note that silicone is not paintable, so choose a paintable sealant where a painted joint is required.
Use in a ventilated area and wear eye protection when cutting the cartridge nozzle or applying overhead.
