Classification data
Preparation	-
Horizontal work	Activator-Primer (Canister) APR01 - Black. Guidance for specification option: Synthetic rubber resin-based primer, developed to provide the necessary preparation of substrates prior to the installation of self-adhesive and torch-applied membranes. The spray application offers improved film thickness speed of application (by up to 50% over roller applied products) and quick drying in a matter of minutes. Coverage: approximately 96 g/m² (300 mm-wide spray one coat, 192 g/m² two coats). Two coats may be required for very porous substrates. Application temperature: +5 to +30°C. Drying time (at 10°C): 5–10 minutes. Colour: black. Recoat time if left exposed: four hours. Suitable substrates: oriented strand board (OSB); plywood; timber; concrete; lightweight concrete or cementitious materials; metal; Bauder self-adhesive underlayers; existing asphalt and bitumen membranes; polyisocyanurate (PIR) insulation. Non-suitable substrates: mica-finished surfaces (e.g. KSD FBS); Laminated paper-foil faced insulation; expanded polystyrene (EPS) or extruded polystyrene (XPS) insulations; BauderROCK or mineral wool insulation; BauderGLAS or cellular glass insulation; copper; thermoplastic waterproofing membranes. SA Bonding Primer. Guidance for specification option: For Self-Adhesive membranes to Concrete and Screeded Substrates. Synthetic rubber-based primer, specially formulated to increase the bond strength of Bauder self-adhesive bitumen membranes to a wide range of substrates, including timber, concrete, brick, metal and most plastics. Coverage: approximately 200–300 g/m² (depending on substrate porosity). Application temperature: +5 to +30°C. Drying time: approximately 30 minutes, dependent upon ambient temperature and material porosity. Colour: black. Recoat time if left exposed: four hours. Suitable substrates: timber, concrete, brick, metal and most plastics. Manufacturer guidance Contact manufacturer to confirm substrate suitability, if required.
