When you seal your home, seal it with silicone. GE-branded 100% silicone and paintable silicone caulks create a seal that never shrinks, cracks, breaks down or washes away – while creating beautiful, long-lasting results. Unlike acrylic caulks, GE-branded silicone caulks can adjust and move with your surfaces, without becoming less flexible or cracking or crumbling over time, and form a permanently flexible barrier that always keeps water, moisture and other elements out.
