Universal Prim Granite – Multi-Surface Bonding Primer
Universal Prim Granite is a ready-to-use bonding primer specifically designed to enhance the adhesion of decorative mortars, renders, and concrete coatings.
Its high-performance formula regulates surface porosity and allows application on a variety of substrates including concrete, tile, stone, and more – whether porous or non-porous. Enriched with granular texture, it offers excellent surface roughness, ensuring a strong grip for subsequent layers.
When Should You Choose This Primer?
This bonding primer is ideal if you need to:
- • Improve adhesion on difficult substrates like tile, concrete slabs, wood, or low-porosity surfaces.
- • Prepare the surface before applying béton ciré, microcement, decorative coatings, or microtoppings.
- • Promote bonding on indoor and outdoor surfaces.
- • Avoid heavy sanding or grinding, thanks to its granular formula that boosts grip.
How to Use It
1. Surface preparation:
Clean the surface thoroughly. Degrease and remove all dust. The substrate must be clean, dry, and sound.
2. Apply the primer:
Use a roller or brush to apply an even coat. Do not dilute the product.
3. Drying time:
Allow to dry for 2 to 4 hours before applying your chosen mortar or decorative finish.
For detailed application guidelines, download the technical data sheet in the “Product Instructions” section below.
Pro Tips
Do not apply below 5°C (41°F) or above 25°C (77°F).
Stir well before use.
Store away from frost, in a dry and well-ventilated area.
Maintenance
Once covered with the final finish, no specific maintenance is required for the primer itself. Its role is to ensure lasting performance and strong adhesion of the top coating.
