ATLAS UNI-GRUNT is a professional-grade, fast-drying priming sealer formulated to stabilize and enhance the absorbency of mineral substrates before applying adhesives, plasters, screeds, paints, or self-leveling compounds. This ready-to-use primer significantly improves bonding strength, prevents rapid water loss from finishing layers, and reduces surface dusting—ensuring consistent results and a longer-lasting finish.

Ideal for use in residential, commercial, and industrial environments, ATLAS UNI-GRUNT creates a uniform, sealed base that maximizes adhesion and application efficiency. Its low-odor, quick-drying formula allows for faster project turnaround, making it a favorite among contractors who value time and performance.

Key Features & Benefits:

• Fast drying time – allows overcoating after just 15–30 minutes

• Improves adhesion – enhances bonding of paints, adhesives, plasters, and screeds

• Reduces substrate absorbency – ensures consistent setting and finish

• Dust-binding action – stabilizes loose particles and prevents peeling

• Water-based and low odor – safe for indoor use and enclosed areas

• Ready to use – no dilution required

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:

1. Surface Preparation:
   Make sure the substrate is clean, dry, and free from dust, grease, and loose material. Repair any cracks or damage before application.
