  • One-component, solvent-based SBS adhesive primer.
  • Used to aid adhesion of Weplus SA VB PL to concrete and various porous substrates.

Skirtings and vertical work

Weplus SA Bonding Agent.

Air and vapour control layer

Weplus SA VB PL.

Guidance for specification option:

  • A multi-layer self-adhesive vapour barrier and carrier membrane made of polymer-modified bitumen with a glass-fibre mat reinforcement and an aluminium foil as top layer.
  • Can be applied over most common substrates such as concrete, plywood/OSB and metal decks.

Insulation

-

Type

PIR insulation.

Guidance for specification option:

Thickness to suit required U-value; consult manufacturer for details.

Liquid-applied waterproofing

-

Type

Wecryl R 230 and Wecryl R 230 thix waterproofing resins.

Guidance for specification option:

  • Two-component, fast-curing and highly flexible.
  • Wecryl R 230 thix is a variant of Wecryl 230 with improved non-sag/ thixotropic properties to reduce run-off when the waterproofing resin is applied to sloping and vertical surfaces. It is used primarily for the waterproofing of details.
