Using Metacaulk 1000 is a breeze. You can apply it with a caulking gun, bulk loading gun, trowel, or pump it directly from the pail. There's no need to mix or dilute it before use. When using it for construction joints, make sure the surfaces are clean and dry. Apply the sealant evenly on vertical or horizontal surfaces for a proper fire - rated seal. For through - penetrations around pipes, conduits, and cables, fill the space around them carefully with the sealant. As for storage, keep it in a cool and dry place. The product has a minimum 3 - year shelf life, but try to use it as soon as possible after purchase for the best performance. If you notice any mold growth, don't worry as the sealant is mold - resistant. However, if the area gets very wet, dry it out promptly. And since it's paintable, you can paint it to match the surrounding surfaces once it's cured. Just follow these simple steps, and you'll get the most out of Metacaulk 1000.
