Indoor and outdoor use — a versatile option for weather-exposed exterior gaps as well as interior gaps around windows and doors.

Smart use cases and scenarios
Seal rough-in gaps around window and door frames before painting to prevent drafts and water intrusion. Use in exterior mulled-joint areas where wind-driven rain could compromise accuracy, and in interior bathrooms or laundry rooms where moisture is a constant consideration. The paintable finish lets you restore or refresh the look of trim without replacing materials, making it ideal for renovations, remodels, or quick DIY fixes.
How to get the best results (quick tips)
- Prep the surface by cleaning and drying thoroughly before application for optimal adhesion.
- Cut the nozzle to the desired bead size and load the cartridge into a standard caulking gun.
- Apply a steady bead along joints, then tool with a smooth, damp tool or finger to achieve a clean, glassy finish.
- Allow surface to dry according to the label before painting or exposing to heavy moisture or direct sunlight.
