Directions for Use

Surface Preparation: The concrete must be clean and free from dust, dirt, grease and debris before applicatio of CS-1500.  Inspect surface for soundness.  When surface is clean, sound and dry proceed with using the CS-1500.
Note:  Make sure the surface is free from frost prior to application.
DO NOT USE petroleum solvents such as Mineral Spirits or Xylene for surface preparation.
Priming: For applications with continuous water immersion ConSeal recommends using a surface primer.  ConSeal CS-80 is specifically designed for ConSeal’s elastomeric sealants.
Application Instructions: Maintain CS-1500 at room temperature before applying to ensure easy application.  CS-1500 may be factory or field applied to seal various construction components.  Work CS-1500 into rough surfaces to optimize surface contact.  CS-1500 is not to be installed in ratios where joint depth is greater than half of the width.  CS-1500 is not designed to bridge gaps larger than 1” or penetrate into joint depth further than ½”.  The use of a backer rod may be necessary in some applications.  If using to fill cracks, avoid air entrapment by filling void with continuous bead of CS-1500.
Packaging and Storage: Available in 10.1-fl. oz. cartridges (298 mL), 20.2-fl. oz. sausages (600mL), 28.5-fl. oz. cartridges (842mL) and 5-gallon pails.
12-month shelf life from manufacture date when stored in a cool, dry area. Elevated temperatures >100° F may reduce shelf life.
Coverage and Full Cure Rates: 10.1-ounce cartridges: ½” diameter bead covers 7.5 linear feet.
Full cure for ¼” bead is 48 hours (77°F at 50% Relative Humidity).
