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: Approx. 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; metal; Bauder self-adhesive underlayers; existing asphalt and bitumen membranes; polyisocyanurate (PIR) insulation.
  • Non-suitable substrates: Concrete decks (new & refurb), Mica finished surfaces (e.g. KSD FBS); Laminated paper-foil faced insulation; expanded polystyrene (EPS) or extruded polystyrene (XPS) insulations; for bonding BauderROCK or mineral wool insulation; for bonding BauderGLAS or cellular glass insulation; copper; thermoplastic waterproofing membranes.


SA Bonding Primer.

Guidance for specification option:

For Self-Adhesive membranes to Concrete.

Bauder SA Bonding Primer is a synthetic rubber-based primer applied by a roller or brush. 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: Approx. 200-300 g/m² (depending on substrate porosity).
  • Application temperature: +5 to +30°C.
  • Drying time: Approx. 30 mins, 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.

Lightning conductor clips are a specially designed secure clip that allows for movement.

  • Bauder Lightning conductor - Type 4: Polyvinyl chloride (PVC) coated or bare conductor.


Bauder rainwater outlets.

Guidance for specification option:

Bauder has a range of insulated or stainless-steel rainwater outlets.

The insulated outlets can be used for maintaining thermal continuity at drainage points. Suitable for warm, cold and inverted roof construction, the high thermal value of the rigid foam body prevents condensation from forming on the underside of the outlet.

Designed for use when connecting to conventional drainage systems, with excellent flow rate performance and is suitable for both new build and refurbishment projects. Outlets are included in the Bauder waterproofing system guarantee as they are integrated components.

Flow rate figures (where applicable) are based on BS EN 12056:3:2000, typically taken using a 35 mm header of water including leaf grille:

 

  • Bauder Bitumen Compact Vertical Outlet DN100: Insulated internal outlet, 6.1 L/s.
  • Bauder Bitumen Vertical Outlet DN70: Insulated internal outlet, 7.1 L/s.
  • Bauder Bitumen Vertical Outlet DN150: Insulated internal outlet, 7.2 L/s.
  • Bauder Bitumen Letterbox Parapet Outlet DN 205 including stainless-steel leaf guard, 2.02 L/s.
  • Bauder Bitumen Parapet Outlet DN 100 including stainless-steel leaf guard, 1.06 L/s.
  • Bauder Bitumen Vertical Refurb Outlet DN70, designed to ensure the maximum flow rate of the existing downpipe is not exceeded.
  • Bauder Bitumen Vertical Refurb Outlet DN95, designed to ensure the maximum flow rate of the existing downpipe is not exceeded.
  • Bauder Bitumen Vertical Refurb Outlet DN145, designed to ensure the maximum flow rate of the existing downpipe is not exceeded.
