Kitchen & Bath Caulk

Kitchen & Bath Caulk keeps wet areas sealed, clean, and good-looking. It fills gaps around sinks, showers, tubs, backsplashes, counters, and fixtures to stop water intrusion that leads to mold, mildew, rotten subfloors, and stained grout. A neat bead also gives joints a crisp finish and reduces odors by blocking moisture and grime.

Choose the right formula for the job. 100% silicone caulk is highly waterproof and flexible, with strong adhesion to ceramic, glass, metals, and many plastics. Many blends include mildew-resistant protection for showers and tubs. Silicone is not paintable, so pick a color (white, clear, almond, or color-matched) that suits the space. Acrylic latex and siliconized acrylic are paintable and easy to clean up with water, making them great for backsplashes, trim, and drywall transitions that see only occasional splashes. Hybrid polymer and urethane options offer excellent adhesion and durability, often with low odor and broader surface compatibility. For natural stone or sensitive metals, look for neutral-cure silicone that won’t stain or corrode.

Key benefits include long-lasting waterproofing, flexibility that handles thermal movement, and improved hygiene through mold and mildew resistance. Many products are low-VOC, low-odor, and fast curing, letting you return the bath to service quickly.

Application tips:
- Remove old caulk completely; clean with alcohol and let surfaces dry.
- Mask edges with painter’s tape for straight lines.
- Cut the nozzle at a 45° angle; use a quality caulk gun for steady flow.
- Tool the bead within the stated working time using a smoothing tool or damp finger.
- Respect cure times (often 24–48 hours) before heavy water exposure and keep the area ventilated.

Whether you need shower caulk, tub caulk, or a paintable kitchen caulk for backsplashes and counters, you’ll find waterproof, mildew-resistant options that make sealing projects easier and longer lasting. Shop sizes from tubes to cartridges and sausages.
