TECHNICAL DEFINITION Ready-to-use, solvent-free adhesive primer for smooth or hardly porous substrates, for interior and exterior use. BETON HAFTGRUND allows to achieve an adhesive bridge between such substrates and certain cementor plaster-based products with a relatively low bond. COMPOSITION AND APPEARANCE Pink, ready-to-use primer with visible grain. Paintlike consistency. ACCEPTED SUBSTRATES Can be applied onto interior and exterior walls, and also onto ceilings. • Smooth cast-in-place concrete • Self-levelling concrete • Old paintwork • Old painted fibreglass coverings APPLICATION BETON HAFTGRUND is to be applied using a brush or a woollen roller. Apply a liberal coat onto the substrate and allow to dry before covering. The drying time will depend on the substrate and ambient conditions. As a general rule, allow for approximately 6 hours.

TECHNICAL DEFINITION Extra-fine finishing filler in powder form for all types of interior jobs. The substrate is now ready to be decorated with paint, wallpaper or any wall covering. COMPOSITION AND APPEARANCE Calcium carbonate, redispersible resin, rheological agent and various additives. Produces a white paste. SUITABLE SURFACES • Wallpaper • paint • wall covering • Plasterboards • Concrete • Old paint • Plaster-based high build filler • Plaster blocks • Cement render • Undercoat TECHNICAL CHARACTERISTICS • Setting time : >24hrs (drying filler) • Powder’s density : 0.8 • Grain size : very fine • pH : 7 • Adhesion : complies with standard NFT 30 608 MIXING FACTOR Use approximately 11-12 litres of water for one 25 kg bag. Allow the paste to rest for 15 min before use. APPLICATION Apply either manually with a steel trowel or a putty knife, or mechanically. Allow to harden and scrape off any possible imperfection before sanding down.

TECHNICAL DEFINITION Ready-to-use coating paste coating specially formulated for use on tapered-edge plasterboard joints, to be used with jointing tape. The coating comes mixed : it is suitable for gluing and finishing the tape. COMPOSITION AND APPEARANCE Resin, water, calcium carbonate, preservatives and various additives. The paste is white in colour. TECHNICAL CHARACTERISTICS Cracking : Up to 5mm thickness with no cracking. APPLICATION Application is carried out manually, spreading the thinned the product with a coating knife across 10 or 15 cm, before laying the tape in position. In the event of projecting vertical angles, use reinforced tape (frame placed at the side of the panel). Apply tape to the internal ceiling corners, making sure that the concrete is free of any trace of forming oil. The surface must be dry and free of any type of powder or insufficiently adherent product.
