Roof Repair Composition and Method for Repairing Roof Shingles

Abstract

The present invention relates to a method for repairing a shingle roof comprising the steps of providing a base aqueous medium selected from the group consisting of urethane, polyurethane, wax particulates dispersed in water, and butyl ether, and mixtures thereof; providing additives selected from the group consisting of sand, silica, polymer particles, plastic fibers, and fiberglass fibers, and mixtures thereof, applying the aqueous medium to a shingle roof, forming a first layer, applying the additives to the first layer, and drying the layers.

What is claimed is: 
     
         1 . A method for repairing a shingle roof comprising the steps of:
 providing a base aqueous medium selected from the group consisting of urethane, polyurethane, wax particulates dispersed in water, and butyl ether, and mixtures thereof;   providing additives selected from the group consisting of sand, silica, polymer particles, plastic fibers, and fiberglass fibers, and mixtures thereof,   applying said aqueous medium to a shingle roof, forming a first layer,   applying said additives to said first layer, and   drying said layers.   
     
     
         2 . The method of  claim 1  further comprising applying additional said aqueous medium, forming a plurality of layers and applying additional said additives to said plurality of layers. 
     
     
         3 . The method of  claim 1  wherein said wax particulates are paraffin wax. 
     
     
         4 . The method of  claim 1  wherein said butyl ether is 2-butoxyethanol. 
     
     
         5 . The method of  claim 1  wherein said additives comprise sand in amount 0-10% by volume of the aqueous medium. 
     
     
         6 . The method of  claim 1  wherein the aqueous medium is applied using a means selected from sprayed on, rolled on, brushed on, sponged on, poured on, and combinations thereof. 
     
     
         7 . The method of  claim 1  wherein drying said layers is done using a means selected from fan, hair dryer, heat gun, and self-drying, and combinations thereof. 
     
     
         8 . A shingle comprising
 a substrate having a surface covered by a solid, thin barrier that adheres firmly to the surface and is formed upon evaporation of water after the application of a non-toxic, water-based, colloidal coating composition including a thermoplastic, elastomeric polyurethane and wax dispersible in water,   wherein said film has a thickness ranging between about 5 and about 100 microns.
