ATLAS ULTRAGRUNT is a highly effective, deep-penetrating primer for reducing and regulating the absorbency of substrates. It improves the adhesion of subsequent layers and ensures an even surface.

• Solidifies and strengthens the substrate – ideal for porous and highly absorbent materials such as plasterboard, concrete and cement screed.
• Improves adhesion – Increases the adhesive strength of tile adhesives, plasters and paints.
• Penetrates deeply – Reduces water absorption and prevents subsequent layers from drying out too quickly.
• Universally applicable – Suitable for indoor and outdoor areas, on walls, floors and ceilings.
• Quick-drying – Can be reworked after a short time.

ATLAS ULTRAGRUNT ensures optimal preparation of substrates and increases the durability of coatings and coverings.
