Sprayer and nozzle are calibrated to achieve the recommended spray pattern of Entry® to maintain snow- and ice-covered entrances between four and eight feet wide making this the ideal sprayer for maintaining entrances of retail stores, offices, schools and large homes. Entry's liquid residue and chloride-free formulation puts an end to the mess and harm caused by granular chloride salts. When used as directed it prevents refreeze to temperatures below 0° F/-19° C. Proprietary residue-free formulation eliminates the mess and expense of cleaning up ice melt materials inside of homes and buildings. Clear liquid formulation eliminates the abrasive affect that granular ice melts have on flooring surfaces. Neutral pH reduces the risk of damage to high value flooring surfaces such as hardwood, tile, granite and marble.
