## Overview

Flex Caulk is a revolutionary waterproof and weatherproof hybrid polymer sealant designed for both indoor and outdoor use. This 6.6 oz, 2-pack product features an adjustable trigger flow nozzle for easy application without a caulk gun. Its advanced formulation adheres to virtually any surface, is UV and chemical resistant, and is fully paintable, making it the perfect choice for a variety of sealing needs.

## Description

Product description Adjustable Trigger-Flow Nozzle. Lets you control the flow, so you can always “dial up” the perfect bead size. Turn it down for pinpoint precision. Crank it up for maximum coverage. Won’t shrink, crack, or become brittle. Unlike other caulks that dry out Flex Caulk’s innovative hybrid polymer formula allows it to expand and contract, and stay completely flexible. Works indoors and outdoors. Flex Caulk is 100% waterproof and weatherproof, as well as chemical and UV resistant. Plus, it’s solvent-free and virtually odorless. Clings to wet and dry surfaces. Even underwater. There’s no need to wait for surfaces to completely dry before caulking them. It even works underwater! Apply to almost any surface. Bathrooms, kitchens, sinks, showers, toilets, backsplashes, counter tops, baseboards, mouldings, pipes, skylights, windows, doors, autos, boats, and more. Made in the USA Flex Caulk is proudly made in America, using globally sourced products. DIRECTIONS Adjust the flow setting to the desired amount. Hold at a 45° angle, push trigger down, while moving the nozzle in an even motion. Remove excess caulk with a dry paper towel, do not use water. After use, secure the “Snap & Save” cap tightly on the nozzle.

Review: Well worth it! - Caulking isn't new to anyone, but for the homeowner or renter who occasionally needs a bit of caulk and wants it ready to use at a moment’s notice, this is the product to reach for. Unlike traditional tubes that require squeezing and can be messy or inconsistent, this applicator features a push-button mechanism with adjustable flow control—making precise application effortless and clean. The design is intuitive and ideal for small touch-ups or quick fixes around the house. While it may come at a slightly higher price point, the convenience, reliability, and ease of use make it a worthwhile investment for anyone who values having the right tool on hand when needed.
