Description

High performance, one-component, high solids, UV-stable, liquid applied polyurethane roof waterproofing system with low odour.


System includes:

  • Surface Finish: Minimum 50 mm thick concrete paving slabs (by others) / Minimum 50 mm thick 20-40 mm well-rounded river washed stone ballast (by others)
  • Protection Layer: S-Felt T-300
  • Waterproofing (Top Coat): Sika® Decothane Ultra
  • Waterproofing (Reinforcement): Sika® Reemat Premium
  • Waterproofing (Base Coat): Sika® Decothane Ultra Base Coat
  • Carrier Layer: S-Vap 5000E SA
  • Insulation Primer: Primer 600/610
  • Insulation: Sikatherm® PIR GT Insulation / Sikatherm® PIR GT Tapered Insulation / Sikatherm® MW DD Insulation / Sikatherm® MW DD Tapered Insulation
  • Insulation Attachment: Sika® C-250 Spray / SikaRoof® Adhesive-200
  • AVCL: S-Vap 5000E SA/SikaBit® VB SA-724
  • Primer: Primer 600/610


- Protection layer:

S-Felt T-300 is a separation, levelling and protection layer made of polyester (PES).


-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.


Approvals/ Standards:

  • British Board of Agrement (BBA) certified No. 14/5158
  • European Technical Approval (No.ETA - 14/0331)
  • External fire performance according to ENV 1187:BRoof(t1) + (t4) over Built up roofing system, classification under BS 476-3: 1958 EXT F. AB
  • Odournet – Report Number 504 - 2014.
