Bonding dispersion concentrate for priming concrete, stone surfaces, and construction boards, and as a mixture additive BAUTEQ Bonding Dispersion is a concentrated adhesion primer for priming various stone surfaces and other materials. It is well suited for all cement systems and can be used as a mixture additive, for preventing wall surface dusting, and for strengthening weak surfaces. BAUTEQ Bonding Dispersion is a vinyl acetate copolymer, known as a low-odor binder. AVAILABLE 2 SIZES: 10 L (weight: 11,8 kg) – 39 € (wo. VAT) 25 L (weight: 29,5 kg) – 93.6 € (wo. VAT) Technical data Unit Value Coverage m² / L 15–50 Final drying time hours 1–3 Density g/cm³ 1.04 pH – 7–8 Color – White The given parameters are measured at 23 °C and 50% relative humidity. Applications For priming floor and wall surfaces before applying levelling compounds or tile adhesives. As an additive to concrete and mortar to improve adhesion and wear resistance. To strengthen plaster surfaces and improve adhesion before applying topcoats or surface finishes. For reinforcing problematic substrates before tiling. To protect stone surfaces against water and alkalis. Suitable substrates Concrete, mortar, brick, natural stone, aerated concrete, wood and chipboard, polymeric materials, etc. Properties As a primer: Excellent adhesion to substrate and leveling layer Excellent resistance to water and alkalis Very good elasticity and resistance to tensile and compressive stresses, even in damp conditions As an additive to concrete and mortar: Improves workability and other mixture properties Improves adhesion to substrate: Increases elasticity and wear resistance, makes the surface more dust-proof Improves resistance to water and aliphatic hydrocarbons Increases early strength of thin-layer mortars in dry conditions Substrates Concrete, leveling compounds, plaster, mortar, brick, natural stone, etc. Wood materials Polymeric materials (paint coatings, linoleum, polymeric coverings) Application conditions Ambient air and substrate temperature must be at least 10 °C, with relative humidity up to 80%. The surface must be clean, dry, and free of dust. Apply with a paint roller, sprayer, or brush. Instructions for use FLOORS: Leveling floors (priming before applying leveling compounds): dispersion : water = 1:3 to 1:10 Concrete finishing layers, manually leveled screeds (strengthening and adhesion improvement): 1:5 to 1:10 Concrete floor surfaces (strengthening weak surfaces): 1:5 to 1:10 WALLS AND CEILINGS: Plaster (adhesion improvement): 1:5 to 1:10 or up to 1:15 Cement mortars 1–5 mm / 5–20 mm (adhesion improvement): 1:5 to 1:10 Plaster and lime surfaces (strengthening weak surfaces, apply dispersion with brush and allow to dry): 1:10, on lime surfaces up to 1:20 AS A CONCRETE AND MORTAR ADDITIVE: Add to mixing water in a ratio of 1:5 to 1:20 On non-absorbent surfaces, use undiluted bonding primer. To prepare the working solution, mix BAUTEQ Bonding Dispersion with water according to the above ratios. When priming, apply so that no puddles form. For surface strengthening, loose dust must be removed before impregnation.
