Directions for Use

Surface Preparation: The concrete must be clean and free from dust, dirt, grease and debris before application of CS-1500SL.
Inspect surface for soundness. When surface is clean, sound and dry proceed with using the CS-1500SL.
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 and CS-85 are specifically designed for ConSeal’s elastomeric sealants.
Application Instructions: Maintain CS-1500SL at room temperature before applying to ensure easy application. CS-1500SL may be factory or field applied to seal various construction components. Work CS-1500SL into rough surfaces to optimize surface contact. CS-1500SL is not to be installed in ratios where joint depth is greater than half of the width. CS-1500SL is not designed to bridge gaps larger than 1” or penetrate into joint depth further than 1⁄2”. 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-1500SL.
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: 1⁄2” diameter bead covers 7.5 linear feet. Full cure for 1⁄4” bead is 48 hours (77°F at 50% Relative Humidity).
