Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match the DUO-SIL color number to the siding manufacturer's shade before ordering, since the numbered colors are tuned for common vinyl and cement siding palettes. Tool the joint immediately after application and clean tools with water for easy clean-up. For joints that need painted over, this urethane acrylic formulation is typically more paint-friendly than pure silicone.
Use in ventilated areas and follow the product label's safety directions; avoid skin and eye contact during application.
Order Bostik DUO-SIL Urethane Acrylic Sealant & Adhesive in the color that matches your project.
