Eco Beton Primer 4T | Acrylic Primer & Absorption Uniformer

Quartz-Infused Acrylic Primer for Microtopping Overlays

Prevent tile joint ghosting and create a high-grip mechanical key with Eco Beton Primer 4T – Acrylic Primer & Absorption Uniformer for Micro-Cement. Formulated as a single-component, water-based acrylic primer infused with fine quartz aggregates, Primer 4T unifies sub-surface suction across mixed-porosity substrates while leaving a textured, gritty key that maximizes overlay bond strength.

When applying thin micro-cement systems over existing tile, variations in suction between glazed tiles and porous grout joints frequently cause visual “tile mirroring” or ghosting lines on the finished coat. Primer 4T neutralizes these absorption differences in a single application, allowing micro-topping overlays like Microbond® and Ercole® to dry evenly for a flawless finish.

Key Benefits of EcoBeton Primer 4T

• Prevents Tile Ghosting & Mirroring: Unifies uneven absorption rates between ceramic/porcelain tiles and porous grout joints to eliminate sub-surface lines.

• Grit-Infused Mechanical Key: Embedded with fine quartz aggregates to form a textured surface key that locks micro-cement overlays into place.

• Ready-to-Use Single Component: No complicated mixing required—simply open, stir, and apply directly to prepared substrates in one coat.

• Multi-Substrate Adhesion: Establishes strong bonding across glazed ceramic tiles, plasterboard, timber, smooth plaster, and concrete screeds.

• Eco-Conscious Water-Based Formula: Low-VOC, low-odour composition designed for safe indoor residential and commercial surface prep.

💡 Pro Tip: Stir Primer 4T thoroughly before and during application to keep the fine quartz aggregates evenly suspended. Apply a generous, uniform coat with a medium-nap roller over tiled walls or floors, ensuring the grit fills into grout lines so the micro-topping gets a consistent mechanical key across the entire surface.
