Environmentally Friendly Coating | Enviro 900 PUR

Supplier: Enviro Systems

Enviro 900 PUR is a 2 pack quick curing, flexible polyurethane resin based, high build coating, designed to provide an anti-slip durable, waterproofing surface treatment for areas of extreme traffic and wear, such as roads, and bridge decks.

Price Guide: POA

Enviro 900 PUR is thixotropic and is suitable for use on ramps. Enviro 900 PUR can be modified to suit different types and levels of traffic and other heavy duty applications by modifying with different size abrasive aggregates.


  • VOC free
  • Flexible
  • Fast curing
  • Cures at low temperatures
  • Quick return to service


Enviro 900 PUR can be applied to a suitably primed concrete substrate where heavy duty wear application exists:

  • Car park decks
  • Walkways
  • Footbridges
  • Pontoons
  • Loading docks
  • Bridge decks
  • Balconies

Enviro 900 PUR is an integral component of the Enviro Trafficable Systems, where structures requiring waterproofing and heavy vehicle traffic exist. See product Data Sheet “Enviro Trafficable Systems”.

Application directions:

Substrate preparation

Concrete must be thoroughly cured, dry, free of oils, grease, dust, dirt, curing compounds and release agents. Gritblast, scarify, or mechanically abrade substrate to remove laitance, loose material and surface contaminants. It is essential that the surface profile should resemble course sandpaper.


Mix Part A to a uniform colour and consistency. Part B is to be added to Part A using a slow speed mixing drill and stirred until uniform. Enviro 900 PUR can be applied by serrated squeegee or notched trowel to an even finish. Aggregate should be uniformly broadcasted to the wet Enviro 900 PUR within10 minutes. Texture will vary depending on type and volume of aggregate used.

Estimating data (theoretical)

The consumption of Enviro 900 PUR will depend upon substrate condition and type. As a guide a 10 kg kit of Enviro 900 PUR will cover about 17m² @ 600 microns dry film thickness (DFT).


Enviro 900 PUR is supplied as a 10 kg Kit. Part A at 6.4kg and Part B at 3.6kg.


Enviro 900 PUR will dry within 6 hours at 25°C (min.) and be fully cured after 7 days.


Hand tools, brushes, power tools can be cleaned with Enviro Thinners No.1 prior to curing.

Shelf life

12 months when stored in a dry, cool environment, in original sealed containers at 5 – 30°C.

Safety advice

When using Enviro 900 PUR always provide adequate ventilation and wear appropriate personal protection equipment (PPE) during use. Avoid contact with skin, avoid breathing vapours. Wear protective eyewear. If inhalation effects occur remove to fresh air. If discomfort persists, any breathing difficulties occur or if swallowed, seek medical attention. Refer MSDS for full details.
