OTTOFLEX® deep primer Product description OTTOFLEX® deep primer is a high-quality synthetic resin dispersion on a butadiene-styrene basis, developed for the adhesion-improving priming and consolidation of substrates. It is solvent-free and ideally suited for indoors and outdoors. Areas of application OTTOFLEX® deep primer is used for priming and consolidating absorbent and less absorbent substrates. It is particularly suitable for plasterboard, gypsum and lime-gypsum renders, gypsum planks, gypsum fibreboards, concrete, aerated concrete, sand-lime brick, brick, masonry, renders, screeds, anhydrite and mastic asphalt screeds as well as various building boards and trowelable floor-levelling compounds. Properties Synthetic resin dispersion on a butadiene-styrene basis Adhesion improvement and consolidation of the substrate Increases load-bearing capacity Dilutable up to 1:2 with water Solvent-free Penetrates deep into the substrate Forms a very good bonding agent for subsequent application layers Improves the adhesion of renders, tile adhesives and wallpaper Store and transport frost-free Complies with exposure classes W1 and W2 to ÖNORM B 3407 GISCODE BSW20 EMICODE® EC 1 Plus – very low emission French VOC emission class A+ Application notes Dilute OTTOFLEX® deep primer 1:1 to 1:2 with water and mix thoroughly. Apply evenly to absorbent and highly absorbent cement-bound substrates with a lambskin roller, brush or paintbrush. Repeat the process for highly absorbent substrates if necessary. After the deep primer has dried, subsequent layers such as tile adhesive, renders or wallpaper can be applied. On screeds with old covering-adhesive residues, apply OTTOFLEX® deep primer undiluted and avoid puddle formation. For consolidating gypsum renders, anhydrite substrates and mastic asphalt screeds, likewise apply undiluted. After drying, the surfaces can be painted, rendered or wallpapered. The drying time depends on ambient factors and is around 2 hours at +20 °C and 50% relative humidity. Consumption depending on substrate condition and absorbency: 100–200 ml/m² diluted, 100–150 ml/m² undiluted. OTTOFLEX® deep primer is the ideal choice for effective substrate pre-treatment before tiling and renovation work. Order now for reliable priming and consolidation!
