Frequently Asked Questions
How much caulk does one tube cover?
A standard caulk tube typically covers 50-100 linear feet depending on bead size. Larger beads use more product.
What caulk should I use for outdoors?
Use silicone or polyurethane caulk for exterior applications as they resist weather and UV damage better than acrylic.
Can I paint over caulk?
Yes, paintable caulk is available. Silicone cannot be painted, so use acrylic or polyurethane for painted surfaces.
How long does caulk last?
Quality caulk lasts 10-25 years. Silicone and polyurethane last longer than acrylic. Reapply as needed.
Should I remove old caulk?
Remove old, cracked, or damaged caulk before resealing to ensure proper adhesion and a clean appearance.
