OSI® RT-600 roof tile adhesive is a professional grade adhesive developed for the repair and installation of concrete, clay, slate or other types of composition roof tiles on existing roofs. It offers long life expectancy with reduced labor and installation costs. It bonds to most building materials producing a water and weather resistant seal against the elements. RT-600 will withstand high temperature roof exposure while maintaining its high tensile and shear strength. OSI® RT-600 roof tile adhesive is ideal for tile repairs since new tiles can be glued to wood or mortar substrates in replacing the broken tiles. The product is easy to use with all "S" type tile and flat type tile applications. OSI® RT-600 can also be used for original installation of concrete, clay, slate or composite type roof tiles in conjunction with appropriate approved installation methods.
