Coetrans Coating Systems

A range of polyurethane-based seamless waterproofing systems designed to refurbish and/ or repair balconies and patios.

Product range:

  • Transparent coatings: Designed for use on sound substrates, the coating cures to a gloss finish. If a lower level of sheen is required, then an additional coat of Coetrans® silky matt topcoat is applied, which will also increase the chemical resistance of the system. The coating can be used to repair broken glass rooflight panels; offer additional splinter protection to glass surfaces.
  • Coloured coatings: Provides a seamless waterproofing system which is elastic and flexible from -40°C to +90°C and is UV and weather proof. Designed to take foot traffic and heavy loads. Provides good water vapour permeability and allows easy waterproofing of details. Can cover cracks up to 2 mm wide. Can also be used to waterproof walls, in vehicle washing bays.
  • Coloured coatings with coloured chips: Additional decorative effects can be achieved by scattering coloured chips to the coloured basecoat, followed by a coat of Coetrans® transparent finish. Coloured chips can be matched to the standard colours in the Coetrans® range and are available in 3 sizes.
  • Coloured coatings with full-surface coloured chips: The coloured chips are scattered over the whole surface to produce a terrazzo-type effect.
  • Trowel coatings: Additional trowel coatings of Colorit Quartz or Coelan® Natural Stone can be added to the Coetrans® liquid plastic systems to give a flat and slip-resistant surface. The trowel coatings can also be used on external steps and risers to refurbish worn areas. Colorit Quartz are furnace-dried, pigmented quartz sands in special grain sizes. Coelan® Natural Stone coatings are made from original marble or granite. Refer to Kemper System Ltd for details of the range of colours available. Trowel coatings should be applied only by trained specialist applicators. They can take higher-than-average loads, yet retain a high degree of elasticity which in turn guarantees permanent waterproofing.
