The sealant is non-staining and non-bleeding, but does not accept paint. Excellent adhesion to multiple substrates. Adheres to clean concrete, gypsum, metal, glass, plastic and wood surfaces without primer. Excellent gunnability, even at low temperatures. Flexible, even at extremely low temperatures (-40° F). Water resistant, even under immersion conditions Non-skinning and non-hardening.
