Ensure that surfaces to be sealed are clean, dry, sound and grease-free. Clean non-porous surfaces with DOWSIL™ R-40 Universal cleaner or methylated spirits and dry thoroughly with a clean, oil and lint-free cloth before application of sealant.

Apply the product using the Geocel ecoSEAL sleeve and a cartridge gun. It is also suitable for use with a standard 400ml Sausage Gun

Clean up

Excess sealant may be cleaned off tools and non-porous surfaces whilst in an uncured state using DOWSIL™ R-40 Universal Cleaner.

Care should be taken not to damage plastic or coated surfaces.
