Roof Reviver Technical Specifications

Please see below for all technical specifications for the Roof Reviver system:

Tilewash

Tilewash is a specifically designed cleaning solution for the removal of moss, moulds and lichen from concrete and Terra Cotta roof tiles.

After application, moss and lichens will deteriorate and loosen. The removal process is accelerated by water blasting.

Coverage

Total surface coverage can be achieved by using 1 Litre of Tilewash per 5 square meters of roof. Treated surfaces may become temporarily slippery.  Avoid discharging into streams and avoid contact with grass and plants.

Application and equipment

Tilewash should be applied by pump driven or hand held equipment which can provide sufficient spray volume for thorough coverage and wetting.

Common application methods are:

  •  Motorised pump units including rotary cleaners
  •  Air Assisted or Airless Spray units
  •  Backpack spray units
  •  Garden hand held spray units
  •  Hand held watering cansRoof Reviver (Tilewash) Product Information
