Choosing the right weatherproofing caulk is essential to ensure long-lasting protection against moisture, drafts, and environmental elements. To make an informed decision, consider the following key factors carefully before purchasing.
Material & Compatibility
The type of caulk material matters significantly. Look for silicone-based caulk for durability and water resistance, or polyurethane caulk for flexibility in various weather conditions. Ensure the caulk is compatible with indoor and outdoor surfaces like wood, metal, glass, or masonry to avoid adhesion issues.
