Surface Preparation: The concrete must be clean and free from dust, dirt, grease and debris before application of CS-1550. Inspect surface for soundness. When surface is clean, sound and dry proceed with using the CS-1550.

Note: Make sure the surface is free from frost prior to application.

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-1550 at room temperature before applying to ensure easy application. CS-1550 may be a factory or field applied to seal various construction components. Work CS-1550 into rough surfaces to optimize surface contact.

Packaging and Storage: Available in 9.5-fl. oz. cartridges (280mL) and 20.2-fl. oz sausages (600mL). 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: 9.5-ounce cartridges: 3/8” diameter bead covers 12 linear feet. Full cure for 1⁄4” bead is 48 hours (77°F at 50% Relative Humidity).
