Best Caulk & Sealant for DIYers
The right caulk keeps water out and gaps sealed for years. Use 100% silicone for wet areas, a hybrid or siliconized latex for general sealing you will paint, and match the product to the surface.
What to look for
- ·Use 100% silicone for kitchens, baths, and anywhere with constant water. It lasts longest but cannot be painted.
- ·For gaps you will paint (trim, baseboards), use paintable acrylic latex or a hybrid sealant.
- ·Look for a mold and mildew guarantee in wet areas, and let silicone cure before exposing it to water.

Frequently asked
Silicone or latex caulk?+
100% silicone is the best for wet areas like tubs, showers, and sinks: fully waterproof and long-lasting, but it cannot be painted. Acrylic latex (often siliconized) is paintable and easy to tool, ideal for trim, baseboards, and gaps you will paint over.
What caulk is best for a shower or tub?+
Use 100% silicone made for kitchen and bath, with a mold and mildew guarantee. It handles constant water far better than latex. Brands like GE Advanced Silicone and DAP Silicone Max are common top picks.
Can I paint over silicone caulk?+
Pure silicone cannot be painted, paint will not stick. If you need to paint the joint, use a paintable siliconized acrylic or a hybrid sealant instead. Save pure silicone for areas that stay unpainted, like tub and tile joints.
How long does caulk take to cure?+
Many silicones are water-ready in 30 minutes to a few hours, but full cure can take 24 hours. Acrylic latex skins over fast but also needs time before exposure. Check the tube and wait before running water or painting.
How do I remove old caulk?+
Cut and pull out the old bead with a utility knife or caulk removal tool, scrape the residue, and clean the joint with the appropriate solvent. A clean, dry surface is essential for the new caulk to seal and last.
