Texprime Primer & Sealer | High-Adhesion Basecoat for Plaster

Ensure maximum adhesion and optimal coverage for your decorative wall projects with Texprime Primer / Sealer. Specially engineered as a textured basecoat for bare drywall and masonry, Texprime creates a strong, uniform surface that locks down porous substrates, prevents uneven color absorption, and maximizes plaster performance.

Whether you are applying traditional lime plasters, acrylic Venetian plasters, or heavy decorative topcoats, Texprime provides the structural bond required for high-end architectural finishes.

Why Use Texprime Before Applying Plaster?

• Textured Grip Base: The subtle, gritty texture gives plasters enhanced mechanical grip, allowing for a faster buildup of layers without slipping or compromising the final finish aesthetic.

• Economical Material Savings: By sealing porous substrates and providing a textured anchor, Texprime significantly reduces the amount of expensive decorative plaster needed to complete your project.

• 100% Lime-Proof Shield: Prevents aggressive alkali burn and chemical reactions when applying lime-based plasters over sensitive substrates.

• Eliminates Color Flaws: Completely seals unpainted drywall, joint compounds, and porous patches to prevent “flashing,” color variations, and uneven suction.

• Low VOC Formula: Features a low-odor, eco-friendly formulation with a VOC content of just 20 g/L.

• Custom Tintable: Can be tinted with universal colorants (up to 8% by volume) to closely match your selected plaster topcoat for seamless coverage.

Technical Specifications & Product Details

Application & Substrate Compatibility

Texprime is formulated to bond securely to both porous and non-porous surfaces, making it an essential first step for:

• Bare, unpainted drywall and joint compound

• Cured plaster and masonry surfaces

• Previously painted interior substrates requiring extra grip

⚠️ Important Product Note: Texprime Drywall Sealer is specifically formulated only for use beneath decorative plaster products. If you intend to finish your wall with standard wall paint rather than plaster, we recommend using Protek Acrylic Drywall Primer/Sealer instead.

Simple Step-by-Step Instructions

1. Surface Prep: Ensure the substrate is clean, dust-free, and structurally sound.

2. Tinting (Optional): Tint Texprime up to 8% by volume with universal colourants to closely align with your decorative topcoat shade.

3. Application: Apply Texprime straight from the container (do not dilute with water) using a roller or brush. Ensure an even coat across the entire surface.

4. Dry Time: Allow the primer to dry completely before applying your Venetian plaster or decorative finish.
