Consumption as a basecoat: ca. 4.0 – 5.0 kg/m
Substrate: Substrates must be sound, clean, dry, free from frost, dust efflorescence and not hydrophobic. Existing mineral and organic based coatings and paints must be sound and well bonded to the substrate (pull off test and/or cross cut test). Substrates for Baumit EWI systems must be inspected and prepared according to the guidance set out in the Baumit EWI Installation Guidelines.
Mixing: Sprinkle the dry powder in to clean water in a tub and mix with an electric hand mixer to a lump free, creamy consistency. Alternatively use a continuous horizontal mixer with a constant water feed. Leave to stand for 5 minutes and remix with the hand mixer. Working time: ca. 1.5 hours. Material which has started setting must not be remixed with water. Mixing with other products (e.g. anti-frost agents or accelerating agents) is not permitted.
Adhesive application for bonding insulation boards: A 50mm wide strip of StarContact is applied around the perimeter face of the insulation board and 3 equally spaced hand-sized adhesive dabs through the centre line. The adhesive layer must be 10 -20 mm thick and provide a bonding contact of at least 40%. Deviations in the background flatness of up to +/- 10 mm can be accommodated in the adhesive layer. After sufficient hardening of the adhesive layer the insulation boards can be sanded down and the dust removed.
