Purpose

Deep-Penetrating Anti-Fungal Primer “DPA Grunt” PR3 by BAYRIS is designed to strengthen all types of fine-porous, loose mineral surfaces with high water absorption, including lightweight concrete, plaster, gypsum, brick, and similar substrates before filling, painting, wallpaper application, tiling, and other finishing works.

The primer helps prevent the growth of bacteria, mould, mildew, and blue stain fungi. It is used to equalise substrate absorbency and improve adhesion between decorative materials and mineral surfaces.

Recommended for use in areas with high humidity, such as kitchens, bathrooms, and basements, as well as rooms with poor ventilation. “DPA Grunt” PR3 by BAYRIS is suitable for both interior and exterior applications.

Characteristics

Deep-Penetrating Anti-Fungal Primer “DPA Grunt” by BAYRIS is supplied ready for use, with no strong odour and no toxic substances. The product penetrates deeply into the substrate, strengthening the surface, equalising absorbency, and reducing the consumption of subsequent decorative and protective materials.

It helps prevent the growth of bacteria, mould, mildew, and blue stain fungi. After drying, it forms a transparent film that does not reduce vapour permeability.

Surface Preparation

The substrate must be visually clean, dry, and free from peeling layers. If necessary, remove dirt, dust, grease, traces of biological contamination, and residues of oil-based or lime-based paints.

Application

Application should be carried out at substrate and ambient temperatures between +5°C and +30°C, avoiding direct sunlight, with relative humidity between 50% and 80%. Do not dilute with water.

Before use, stir the anti-fungal primer thoroughly. Apply evenly using the “wet-on-wet” method with a brush, broom, roller, or spray equipment until the substrate is fully saturated.

Immediately after application, clean all tools with water. The next stage of finishing work may begin after 4–6 hours.

Warning! Any modification of the ready-made product, misuse, or application contrary to the manufacturer’s instructions may significantly affect product quality and performance. Suitability for specific materials and compatibility with other products must be determined by the user through trial application. The manufacturer accepts no responsibility for direct or indirect damage resulting from improper use or conditions beyond its control.

Coverage

Approximate consumption: 0.15–0.25 L/m² per coat depending on substrate type, absorbency, application method, and tools used.
