Henkel Almost as exciting and productive as watching paint dry is waiting 24 hours for caulk to dry. For busy builders and remodelers with better things to do, Polyseamseal EST Speed Seal reduces that waiting period to two hours. The silicone caulk, appropriate for kitchen and bath applications, creates a flexible, watertight seal and resists mold and mildew. It comes in white and clear. 800.321.1733. www.henkel.us.
