Tiefengrund No. 301

AURO Tiefengrund No. 301 is the ideal substrate preparation for plaster and wall paint on highly or unevenly absorbent wall materials, such as plasterboard and gypsum fibreboard or mineral interior plasters. As a high-yield concentrate, a small amount of product covers large areas.

The biogenic binder REPLEBIN®, developed in-house by AURO research, ensures professional product properties and a low-emission formulation: better substrate compatibility and adhesion, oil-free, with low drying odours and no yellowing in the dark.

Advantages at a glance

• Hochergiebiges Konzentrat
• Hohe Festigungswirkung
• No added solvents and no added preservatives
• AgBB-compliant
• Can be applied by brush or spray equipment
• Can be overpainted with all AURO wall paints

Anwendung & Verarbeitung

Shake well, then dilute 1:1 with water. Apply the product evenly with a brush, 1 to 2 times depending on the absorbency of the substrate. Any AURO wall paint can be used for the subsequent coating.

Tip: Highly or unevenly absorbent substrates such as plasterboard should be primed to achieve a uniform surface and to avoid irregular, dull patches in the subsequent wall paint.

Frequently asked questions

When do I need a penetrating primer?

On highly or unevenly absorbent substrates such as plasterboard, gypsum fibreboard or mineral interior plasters, the deep primer ensures uniform absorbency and prevents irregular, dull patches in the subsequent coat.

Do I need to dilute the deep-penetrating primer?

Yes, the concentrate is diluted 1:1 with water and then applied.

How do I apply the deep-penetrating primer?

With a brush or by spraying, 1 to 2 times depending on the absorbency of the substrate.

What can I paint over it with afterwards?

With any AURO wall paint, e.g. Wall Paint No. 321 or Professional Clay Paint No. 331.

Is the penetrating primer free from added preservatives?

Yes, entirely free from added preservatives and added solvents, and AgBB-compliant.

What coverage does the concentrate give?

2 litres are sufficient for around 40 m², 5 litres for around 100 m² – depending on the absorbency of the substrate.
