- Waterproof performance: Confirm 100% silicone formulation for reliable moisture sealing and weather resistance.
- Flexibility and adhesion: Look for flexible bonds that tolerate surface movement and withstand shrinking or cracking.
- Cure time: Consider time-to-water-ready or rain-ready claims to fit your project timeline.

- Paintability: If you plan to paint after sealing, ensure the product is paintable or choose a paintable variant if provided.
- Surface compatibility: Most silicone caulks adhere well to ceramic, glass, metal, and tile; test on delicate surfaces first.
