Sharktooth High-Adhesion Primer & Undercoat for Specialty Finishes

Ensure maximum grip and lasting durability for your decorative projects with Sharktooth Primer / Undercoat / Sealer. Formulated specifically for hard-to-paint substrates, this heavy-duty undercoat creates a high-tack, micro-textured surface. As a result, decorative plasters and specialty finishes can easily bond to slick, challenging materials.

Whether you are applying Venetian plaster over glossy painted walls, MDF, or non-porous laminates like Formica, Sharktooth delivers the ultimate structural anchor.

Key Benefits & Highlights

• Superior Surface Bonding: Engineered specifically to adhere to shiny, pre-painted surfaces, glass-like substrates, Formica, wood, MDF, and plywood. Therefore, heavy sanding is rarely required.

• Lime-Proof Formula: Provides exceptional chemical resistance for traditional lime plasters and mineral finishes. Consequently, it works flawlessly on both porous and non-porous surfaces.

• Reduces Plaster Consumption: The micro-textured base locks in topcoats. Because of this, total material usage is reduced, making expensive plaster applications far more economical.

• Faster Layer Build-Up: Allows applicators to build thin or heavy plaster layers much faster. Additionally, it prevents slipping and dragging without affecting your final finish.

• Custom Tintable: Can be tinted with universal colorants up to 8% by volume. As a result, you can closely match your topcoat and eliminate basecoat show-through.
