IKO Water Based Adhesive is a solvent-free primer intended for use with IKO self-adhering roof membranes, IKO AquaBarrier™ self-adhering membranes or IKO heat welded membrane products. IKO Water Based Adhesive is suitable for application on most substrates including wood, glass mat/gypsum sheathing, masonry, concrete and metal. IKO Water Based Adhesive dries to a high tack, providing excellent adhesion properties during the application process. The product is effective on both horizontal and vertical surfaces. Actual drying time depends on the ambient temperature and humidity level during application. IKO Water Based Primer may be applied using a brush, a roller or by mechanically spraying. All substrates should be clean, dry and free from dust, dirt, oil and grease. IKO Water Based Adhesive cleans up easily with mineral spirits.
