Description
Bostik Universal Acrylic is a high-quality, versatile acrylic sealant formulated using an acrylic dispersion system. Once applied, it cures by water evaporation, forming a soft plasto-elastic rubber capable of accommodating minor joint movements. Designed for professional interior finishing and general construction applications, it provides excellent adhesion without primer on most common building substrates, including slightly damp surfaces. Its low odour, easy workability, and paintability with both water-based and synthetic paints make it suitable for sealing gaps, cracks, joints, and finishing edges in residential, commercial, and renovation projects.
