WETPOUR RUBBER DIY INSTRUCTIONS

Guidance for the installation of Wet Pour Rubber Crumb

Rubber Crumb products have been developed to work with our PU Binder and laid as a continuous wet pour surface.

If you are unsure of the depth of surface required to meet any Fall Height regulations or recommendations, please contact us and we will advise you.

Wet Pour Rubber Crumb can be laid on existing solid surfaces such as bitumen or Concrete but you must ensure that there is good drainage. We do not recommend laying directly on to unprepared surfaces such as bare soil or grass. If the area you intend to use is currently soil, grass or other unmade surface then we strongly advise that a subbase of a minimum of 100 mm of a compacted aggregate, such as crusher dust/cracker dust should be laid first with a geotextile membrane laid on top to inhibit weed growth.

  • A firm edging should be installed around the perimeter of the area either using treated timber or other permanent edging.
  • Wet Pour Rubber Crumb should not be laid in damp or cold conditions, 5⁰c is the minimum temperature advised. Our PU Binders are moisture activated and any contact with moisture either through rainfall or existing damp surfaces during installation will cause the binder to react and cure much more quickly, resulting in potential problems with the finished surface. Check there is no rain
    forecast for at least 48 hours from when you start the installation.
  • The depth of the top layer is usually 15 mm minimum +. To mix the Rubber Crumb and Binder it is common practice to use a forced action pan or paddle mixer, which are widely available for hire on a daily or weekly basis.
  • For the Top Layer we recommend a mixture ratio of 4 kilos of Binder per 25 kilos of Rubber Crumb.
  • When you’ve prepared the sub base you can begin the mixing of crumb and binder. Allow the material to mix for between 4-6 minutes per batch. Reducing this mixing time will result in the surface taking much longer to set. However leaving it too long mixing will make it more difficult to spread so this timing is critical. When the batch has been mixing for the correct length of time, empty it from the mixer in to a wheel barrow and take it immediately to the site to be poured out and laid.
  • The mix should be troweled evenly over the area to the required depth using a depth block and straight edge then lightly rolled to ensure a level surface. As the rubber crumb is obviously very adhesive at this point we advise continuously lubricating your trowels and rollers with ͚soapy͛ water/trowel lubricant or Diesel fuel.
  • We recommend that you coat the edging boards with a layer of binder as you work up to them with the rubber crumb. This will help to create a strong adhesion between the finished surface and the edging.
  • White Spirits may be used to clean your tools once you’ve finished.
  • The area should be ready to walk on within 24 hours but we recommend it not be used for 72 hours after completion.
