Typical Applications:
ATLAS UNI-GRUNT is designed for priming:
Concrete, cement-lime plasters, cement screeds, and gypsum substrates
Interior and exterior mineral surfaces before tiling, painting, or plastering
Floors and walls prior to applying self-leveling compounds or adhesives
Highly absorbent or porous substrates to regulate water uptake
Professionals in construction, renovation, flooring installation, and painting frequently choose UNI-GRUNT for its reliable performance, ease of use, and versatility across multiple finishing systems.
Instructions for Use:
Surface Preparation:
Make sure the substrate is clean, dry, and free from dust, grease, and loose material. Repair any cracks or damage before application.
Application:
Stir the product thoroughly before use. Apply an even layer using a roller, brush, or sprayer. Avoid pooling.
Drying Time:
Allow the primer to dry completely before proceeding with further work. At standard conditions (+20°C, 55% RH), drying takes approximately 15–30 minutes.
Coverage:
Depending on substrate absorbency, 1 liter of UNI-GRUNT covers approx. 5–10 m².
Tool Cleaning:
Clean tools immediately with water after use.
ATLAS UNI-GRUNT is the trusted choice for professionals who demand a reliable, quick, and effective priming solution that enhances the performance of every layer that follows. Use it to build quality from the ground up—starting with a properly sealed base.
