For general home maintenance, this offers convenience and effective sealing. ## How to use 1. Ensure the area to be sealed is clean, dry, and free from rust, dirt, grease, or loose paint. For best adhesion, lightly sand glossy surfaces and wipe clean. Remove any loose material. — Prepare the Surface 2. Shake the can vigorously for at least 2 minutes after the mixing ball begins to rattle. Hold the can upright, 10-16 inches from the surface. Spray in a steady back-and-forth motion, overlapping each stroke. — Shake and Spray 3. Apply thin, even coats. Allow 30 minutes to dry to touch between coats. For optimal protection, apply multiple coats until desired coverage and seal are achieved. Do not apply in temperatures below 50°F (10°C) or in direct sunlight. — Apply Multiple Coats 4. Allow the final coat to dry for at least 24 hours before painting. The coating can be top-coated with latex or oil-based paints. Ensure good ventilation during application and drying. — Top-Coat and Cure ## Product details | Field | Value | |---|---| | Base Type | Oil-based | | Key Feature | Flexible rubber coating | | Water Resistance | Waterproof | | Top-Coating | Can be top-coated with latex or alkyd based paints | | Prop 65 Chemicals | Di(2-ethylhexyl) phthalate (DEHP) | | Application | Spray | | Recommended Surfaces | Gutters, roofs, flashing, ductwork, PVC, masonry, concrete, drains | | Interior/Exterior Use | Yes | | Cost per use | Covers up to 8 sq. ft. at ₹2,692 — ₹337 per sq_ft | | Shelf life after opening | 12 months (typical for sealants) | | Contraindications | Not for structural gaps or high-pressure water applications.
