  • Lubricant for smoothing caulking joints and method of use
    Patent number: 6656886
    Abstract: A water-based, phosphate-free, non-toxic, and biodegradable lubricant used for smoothing and shaping a bead of caulking compound sealant, and a method for its use, which can be easily removed from the caulking compound sealant bead after it is allowed to cure. Applied to a bead of newly dispensed caulking compound sealant, the present invention lubricant will not chemically interact with, prevent the curing of, or otherwise contaminate the caulking compound sealant. Instead, direct application of the present invention to a bead of caulking compound sealant, or application via a finger or man-made tool, and subsequent smoothing with the finger or tool will allow correction of all imperfections in the caulking bead prior to curing. Applications may include, but are not limited to, use in construction, marine, automotive, aircraft, electronic, and manufacturing industries with caulking sealants made from silicone, elastomer, urethane, polyurethane, polymers, butyls, poly-sulfide lithoseals, thiokols, and epoxys.
