Powafix Powabond Key Coat - 5L

PowaFix Powabond Key Coat - 5L is a high-performance bonding primer designed to improve adhesion between surfaces and subsequent coatings. Formulated by PowaFix, this product is ideal for preparing porous or low-adhesion substrates such as concrete, brick, plaster, and fibre cement before applying paints, renders, or waterproofing membranes. It ensures a durable, long-lasting bond, reducing the risk of delamination or peeling over time.

The 5L container delivers consistent coverage, with one litre typically treating between 8 and 10 square metres depending on substrate porosity. The water-based formula dries to a tacky, receptive surface within 30 to 60 minutes under standard conditions, allowing for timely top-coating. It is compatible with a wide range of finishes including acrylics, epoxies, polyurethane, and cementitious coatings. The product is low-odour, VOC-compliant, and suitable for both interior and exterior applications.

Using Powabond Key Coat enhances the performance and longevity of top coatings by sealing dust, stabilising friable surfaces, and promoting uniform absorption. It is particularly effective on challenging substrates like smooth concrete or aged masonry where standard primers may fail. Contractors and DIY users rely on it to prevent costly rework and ensure professional results in renovation, construction, and maintenance projects across residential and commercial settings.
