17-0559 Ankocryl Interior ISO Primer Grey is a professional water-based grain-filling isolating primer developed for interior wooden components. Designed to provide exceptional tannin and stain-blocking performance, it helps prevent discolouration caused by oak and other tannin-rich hardwoods while creating a smooth, even surface for finishing. With excellent coverage, outstanding sanding properties, and fast drying, it provides the ideal foundation for coloured interior coating systems. Its grey base helps improve coverage, colour development, and consistency when applying darker or more vibrant topcoat colours.

Ideal Applications

Ideal for interior doors, door frames, joinery, furniture, cabinetry, MDF, and other interior timber components. Particularly suited to oak and tannin-rich hardwoods where stain blocking is required to prevent discolouration and achieve a flawless decorative finish. Recommended where dark, bold, or highly saturated topcoat colours are being applied and enhanced colour consistency is required.

Application & Drying

Apply to clean, dry, and properly prepared timber using suitable spray equipment. Once dry, lightly sand the surface where required before overcoating with 17-087X Ankocryl Interior Topcoat Colour. Where tannins or extractives remain visible after the first coat, apply a second coat after approximately 24 hours to achieve optimum stain-blocking performance. Follow the technical data sheet for the recommended application guidance and drying schedule.
