Red Devil Latex Caulk Editorial Review
The Red Devil 0841DS RD-DS 181 Acrylic Latex Duct Sealant is a high-quality product suitable for sealing metal, fiberglass, and flex ducting systems. It can also be used on painted ducts and exterior ducts that have been sealed with another product. The temperature range, after curing, is -20F to 180F, perfect for sealing HVAC ducts. The Consistency is good and easy to apply, and it cures in 2-3 days. However, according to customer reviews, the packaging needs improvement as the container may arrive cracked or open, causing spillage during shipping. The product's odor is strong, and it should not be applied to wood, heater vents, or used to patch up holes.
