-Waterproofing (top coat):

Decothane® Ultra is a cold-applied, one component, seamless, highly elastic, UV stable and moisture-triggered polyurethane membrane with significantly reduced odour. It cures to form a seamless,

durable and weather-resistant waterproofing solution for exposed roof areas.

• Low maintenance
• One component - no mixing, easy and ready to use
• Cold applied – requires no heat or flame
• Minimal odour - suitable for odour sensitive projects
• High solids
• Seamless membrane
• Compatible with Sika® Reemat Premium – easy to detail
• Easily recoated when needed - no stripping required
• Elastic - retains elasticity even at low temperatures
• Good adhesion to most substrates – see table
• Free from rain damage almost immediately on application

-Waterproofing (reinforcement):

Sika® Reemat Premium is a glass fibre mat reinforcement for Decothane® and Sikalastic® Liquid Applied Membrane systems.

-Waterproofing (base coat):

One-part low odour polyurethane liquid applied base coat for use in conjunction with Decothane Ultra systems.

-Carrier Layer:

• S-Vap 5000E SA is a multi-layer self-adhesive vapour control layer made of polymer modified bitumen with a glass-fibre mat reinforcement and an aluminium foil as top layer.

- Insulation:

Sikatherm® PIR GT/Tapered is an insulation board for flat roofing. It is faced on both sides with a coated glass tissue bonded to the insulation core and produces a tough, durable, light weight insulation board.

Sikatherm® MW DD/Tapered is an insulation board, faced with a mineral fibre tissue, bonded to the insulation core during the manufacturing process. The core of Sikatherm is high performance mineral wool with a typical density of 220 kg/m³ (top layer).

- AVCL:

• SikaBit® VB SA-724 is an SBS modified bituminous, self-adhesive air vapour control layer. It is reinforced with aluminium foil and a dimensionally stable non-woven polyester inlay. The underside has a removable liner over the adhesive compound for an easy application. It can be applied to wood, metal and concrete substrates. Top surface finish: sanded bitumen. Weight:~3.0 kg/m².
• S-Vap 5000E SA is a multi-layer self-adhesive vapour control layer made of polymer modified bitumen with a glass-fibre mat reinforcement and an aluminium foil as top layer.

- Primer

• Primer 600: Synthetic rubber and resins based primer.
• Primer-610 Spray: Solvent-based synthetic-rubber bonding agent in a pressurized canister system.
