GoldFlex #615 Asphalt Crack and Joint Sealant is a premium hot melt, polymer-modified, asphalt crack sealant designed for use on asphalt, concrete, streets, and parking lots. GoldFlex #615 Cracker sealant is a blend of SBS polymer modified asphalt, fillers, and additives designed as a hot applied, premium pavement joint and crack sealant. Application to prepared joints or cracks is by hot application from a heated melter then squeegeed into place. Only 100% new polymer is used, with no recycled polymer, rubber, or reclaimed rubber, giving superior performance over a variety of temperatures and climates. It is packaged in easy-to-use 35 lb. “bricks” that are wrapped with meltable poly in an individual cardboard carton and palletized.
For best application, use an oil-jacketed melter and dispense the material between 340º – 350ºF. Never exceed 380ºF, as product performance will be degraded. Cimline and Step Equipment melters are commonly used by contractors. Goldflex will also work with direct fire melters if proper care is taken to limit flame intensity. A gentle flame works best when using this equipment – avoid over-heating material. Only apply to cracks, normally 1/4″ and wider, and apply with either a pressure feed wand system or gravity pour pots. Use a “V” or “U” shaped squeegee to strike-off material and avoid excess “bands” on the surface.
