| Characterization: Bayblock Prime NS is a single-component, water-based, general purpose primer. Properties / Applications: Bayblock Prime NS is designed for the preparation of surfaces for the application of elastomeric coatings and spray polyurethane foam. This material can be easily sprayed, rolled, or brushed on and provides excellent adhesion to most surfaces. Bayblock Prime NS primer requires minimal set time before foam application. This product is water reducible. As with any product, use of Bayblock Prime NS primer in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
