Ready-to-use acrylic polymer-based waterproofing compound for use on construction surfaces such as concrete, filler, plaster, drywall, chipboard, and wood. Designed to create a flexible, waterproof barrier in indoor areas exposed to moisture, including bathrooms, showers, toilets, kitchens, and saunas. Ideal for use before tiling with ceramic or stone tiles, including application over existing tile coverings with good adhesion. Not suitable for swimming pools. The compound forms a seamless, elastic film with excellent adhesion and prevents mold growth. Solvent-free.

The surface must be even, dry, and free from dust, grease, or substances that reduce adhesion. Rough surfaces must be sanded or filled. Absorbent or chalky surfaces should be primed with ELVI TIEFGRUND A-05. Stir thoroughly before use.

First, apply the compound to corners, junctions, screw heads, and drains using a brush. Embed a reinforcing waterproofing tape into the wet layer and coat over it again. Apply the first coat to the remaining area with a roller or brush. Allow to dry completely, then apply the second coat. Application temperature: above +10°C. Tiling can begin approximately 24 hours after full drying using ELVI universal tile adhesive or similar elastic adhesive. Joint grouting should be done 24 hours after tiling.
