Preparation

-

Horizontal work

Bauder SA Bonding Primer.

Guidance for specification option:

Only for concrete decks. Used to seal substrate and improve adhesion.

Bauder Activator Primer.

Guidance for specification option:

A synthetic rubber resin-based material using a non-flammable solvent and propellant system. Bauder Activator-Primer has been specifically developed to provide the necessary preparation of substrates, insulations and underlayers prior to the installation of Self-Adhesive membranes.

Skirtings and vertical work

Relevant LiquiTOP Primer.

Guidance for specification option:

Upstands and details to be primed first.

 

Purpose:

Relevant Bauder LiquiTOP Primer substrate primer to seal and prepare dry surfaces of a variety of common substrate material prior to the application of receiving the new Bauder Cold Applied Liquid Waterproofing System to upstands and details only. The following primers must be used as required:

  • Bauder LiquiTOP General Purpose Primer: For timber, plywood or OSB/3 or KLH, absorbent asphalt, exposed bitumen, bitumen bleed, non-porous concrete, screed, blockwork 
  • Bauder LiquiTOP Epoxy Primer: For exposed metals.
  • Bauder LiquiTOP Reactivation Primer: For existing liquid waterproof coatings (subject to adhesion testing) - Bauder LiquiTOP PVC Primer: For existing PVC single ply membranes (subject to adhesion testing) 

Application:

Refer to the current relevant Bauder LiquiTOP Primer product datasheet. 

Note:

For other substrates, consult the Bauder Technical Department for required preparation methods and priming.

Air and vapour control layer

TEC DBR 06.

Guidance for specification option:

Suitable substrates: Metal, plywood and oriented strand board (OSB). Not suitable for concrete decks.


Self-adhesive elastomeric bitumen air and vapour control layer (AVCL), with an aluminium foil facing for vapour impermeability. The bottom is a peel off release film, covering self-adhesive bitumen.


The product is thinner than other Bauder air and vapour control layers and is therefore lightweight. For mechanically fixed insulation only.

  • Width: 1.25 m.
  • Length: 32 m.
  • Thickness: 06 mm.
  • Weight: 0.6 kg/m².
  • Reinforcement: Aluminium foil and 50 g/m² polyester.
  • Tensile strength: Length ≥950 N/50mm and Diagonal ≥750 N/50mm.
  • Cold bending test: -40°C.
  • Elongation at break: Length and Diagonal ≥ 4%.

KSD FBS.

Guidance for specification option:

Suitable substrate: Concrete.


Robust, self-adhesive elastomeric bitumen air and vapour control layer (AVCL), with a mica finished upper surface to allow easy bonding of insulation using appropriate Bauder Insulation Adhesive. One side lap features an 80 mm wide glass fleece along the underside, and a 100 mm strip of aluminium foil above. The other side lap has a thermofusible film on the top surface. This arrangement ensures that laps are heat sealed using hot air or gas torch as appropriate to extrude a bitumen bead, thus ensuring waterproofing integrity.


  • Width: 1.08 m.
  • Length: 10 m.
  • Thickness: 2.5 mm.
  • Weight: 2.5 kg/m².
  • Reinforcement: Polyester coated aluminium foil and 200 g/m² glass fleece.
