*FIX-R Classic Primer 10 Required

6. Liquid 10 Thixo

FIX-R Classic Liquid 10 Thixo is a unique additive developed to solve application difficulties of FIX-R Classic Liquid 10 in severely inclined, uneven or completely vertical substrates.


  • Reduces the number of coats of Liquid 10 required when used together
  • Achieves a uniform thickness on uneven substrates by modifying the rheology of the Liquid 10
  • Greatly enhances the thixotropic properties of Liquid 10 without affecting its final viscosity
  • Available in 1Kg plastic sausages for easy addition into Liquid 10 without significant loss

Ideal uses

  • Waterproofing of vertical flashing details on a roof
  • Waterproofing and protection of an uneven substrate
  • Waterproofing and protection of corrugated metal roofs

7. Tape 10

FIX-R Classic Tape 10 is a self-adhesive tape made of a butyl rubber compound protected by a fleece in polypropylene.

The tape has been developed for applications where it is necessary to have a high adhesion property on materials like concrete, gypsum boards and marble.


  • Excellent adhesive properties
  • Excellent heat stability
  • Excellent adhesion at low temperatures
  • High workability, plasticity and formability
  • Solvent free

Ideal uses

  • To seal and reinforce the joints between timber decks, roof sheets and approved insulation boards
  • All surfaces must be primed using Classic Primer 10 and allowed to fully cure before tape application

8. Fabric 10

FIX-R Classic Fabric 10 is a non-woven, spun bound, polypropylene reinforced fabric. Use when applying FIX-R Classic Liquid 10 over existing Built-Up-Felt and Asphalt roofs.
