LOW VOC: Meets CARB VOC limits

BETTER WEATHER RESISTANCE: Exceeds ASTM Test Method C920, TTS-230, with +/- 25% movement capability. A caulk with more movement capability provides better weather resistance because it is less likely to crack when exposed to expansion or contraction that can occur with temperature fluctuations. Cracking can lead to gaps where air and water can pass.

PAINT-FRIENDLY: Caulk won't cause most paints to crack, fade or change sheen when painted over as the paint dries.

Don't Waste Time and Energy

Not all caulk is the same. Because silicone is permanently waterproof, flexible, and shrink-/crack-proof, unlike acrylic, it won't leave gaps or cracks for air and water to seep through over time. Those leaks can lead to water damage, mold growth, and higher energy bills—all of which can translate into your lost time (when you have to do the job again), lost energy, and lost money.
