What Customers Are Saying

Customers overwhelmingly praise this caulk for exceptional sealing performance and ease of application. The latex formula applies smoothly and cleans up easily, even for non-experts. Reviewers consistently report it seals windows, doors, and outdoor gaps effectively, with many noting years of reliable use through weather changes. Most highlight its paintability, though some mention it requires longer than advertised before painting. A few report minor stickiness or dispensing issues, but these concerns are vastly outweighed by strong satisfaction with durability and performance.

Works well with some caveats

 Would Recommend

Easy to apply, work with, clean-up and smooth out and doesn't collect and attract dirt and dust like some. It also has good stretch and adhesion. The downsides - it shrinks more than many other silicone's once cured and also yellows slightly. I've used this for years and only recently noticed the slight yellowing after curing so maybe it's something that changed in the formula or I got a bad batch.
