34 Utility Grade Asphalt Cotton Fabric

Karnak #34 Utility Grade Cotton Fabric is a strong cotton fabric, thoroughly impregnated with highly specialized bitumens. This exclusive Karnak process permits the fabric to unroll easily, without distortion. It can be applied smoothly and without wrinkles. The open mesh construction of the fabric allows the surface coatings to penetrate through and interlock, thereby providing a firm mechanical bond between coatings, and insuring long life of the application. This strong elastic interlocking system is very pliable and prevents rupture due to expansion and contraction of the applied surfaces. Karnak #34 Utility Grade fabric was developed to meet the need for an economical, lighter weight fabric.


Karnak #34 Utility Grade Fabric is useful for roof repairs, flashings, parapet walls, coverage of entire roof areas and for waterproofing of building foundations, retaining walls, and wherever construction is exposed to the elements.
