Big Stretch®

  • BIG-BigStretch-Garage

    Homes move. Window frames pull away from the siding or doors shift against the brick. They move when the temperature changes, the rain falls, the wind blows or the earth quakes. Most caulks can’t take it – they dry hard and crack. That’s why you need Big Stretch® high performance water-based sealant.  Its powerful adhesion and extreme elasticity will stick, twist, bend, compress, and stretch – more than 500% of original size! – to handle most any movement your home can dish out, all without cracking.

    • vents
    • soffits
    • eaves
    • baseboards

    “I had some crown molding on a project we did a couple of years ago, develop cracks between the ceiling and crown. The old caulk had to be removed and new caulk and paint applied. I paid for that trim finishing three times. The first time, the second to remove, and the third to fix. Needless to say we went back with Big Stretch…This is a professional product being available to consumers. You won’t be disappointed…This is my high end go to caulk when conditions are extreme and results need to be guaranteed. Five stars easy.” – M Masaki MM, review

    The best caulk (for its intended use) that I’ve used in 35 years of residential, commercial construction. It’s the proper consistency for intended use, works well, has great adhesion, and water clean-up.” – Craig Jaynes, review

    I started using Big Stretch a few years ago for between the Masonite siding. Regular caulk falls out after a few years and you have to refill the crack and then try to touch up the paint (almost impossible). I tried Big Stretch. It worked so well that I use it everywhere. It has also transformed my sales presentation and dramatically improved the close ratio. I won’t let my crews carry any other caulk on their trucks and repairs are now almost nonexistent. – D. Perran, Paint Co, NC

    “As of this writing, I have been using this product now for well over 2 years.  I tried to figure out how many tubes I have purchased in that time and I am coming up with about 350.  I have yet to have a crack or failure, or a call back for a caulking issue.” – Joe Prin, web review

    “Since that fateful day, I’ve not looked back. We’ve used this caulk in almost every situation that calls for latex caulk. This includes all crown molding, baseboard, or other molding surface installs, our siding install, and various other useful applications for the Big Stretch. It has worked flawlessly since we first installed it on our dining room crown molding. The dining room crown was installed in October 2004 and is still crack free almost seven years later.” Web review
