• How do I use Rendergun?

  1. Connect the Rendergun to a compressed air supply with the hose supplied with the unit. (Compressed air requirement: 35 cfm @ 50 psi (1000 litres per minute @ 3.5 bar)). Extra lengths of standard compressor hose may be added as required.
  2. Simply scoop up the mix with the hopper of the Rendergun from the wheelbarrow or container of mix. No awkward loading or filling of the tool is necessary; just use the Rendergun itself as a scoop.
  3. Point the Rendergun at the wall from a distance of between 1 and 3 feet and press the trigger.
  4. When the trigger is pressed, air is released from the nozzles inside the base of the hopper, drawing the mix at speed through the holes in the front plate of the unit and throwing it firmly on the surface.

• Does Rendergun require a special render mix?

  No! Any render mix that you would apply by hand can be applied with Rendergun.

  Sand and cement render, lime render, insulated renders, Tyrolean, wet pebbledash, whatever type of mix or render you want to apply, all can all be put on the wall much more quickly and efficiently with Rendergun than is possible by hand!

  Rendergun is distributed by Anglia Lime Company, manufacturers of lime-based building products including a range of lime renders suitable for use with Rendergun.

• How thickly should I apply with Rendergun?

  As thickly as you wish. The same principles apply as if you were putting on the render by hand.

  However if required, Rendergun enables you to achieve thinner or thicker coatings than are obtainable by hand. For example:

  Rendergun can easily and very quickly give a thin, spiky first coat on a surface which will provide an excellent key for subsequent coats.
  Suitable mixes can be applied as thickly as required. Insulating renders, for example, can be applied 40 mm / over 1" thick in one go.
