Postcrete may be used for the purposes of fixing domestic posts.

The amount of Postcrete required will depend on the size of hole and post. For example: 1 bag = square post 10 cm (4”) with a hole 20 cm (8”) wide x 75 cm (30”) deep. Please refer to Product Datasheet for more details.

Postcrete may not be used for general concreting, screeds, mortar, grout or render.

If a particular compressive strength is required, Postcrete should not be used.

For best results follow these instructions:

  1.  Dig hole to correct depth and width relevant to post size (see table on reverse).
  2.  Fill hole with water to a third of the depth.
  3.  Pour in Postcrete evenly around post until no standing water is visible (powder completely covers water surface). Sprinkle water on top of powder.
  4.  Position and level post as required. Setting will take place in 5 to 10 minutes.
  5.  When set, cover top of hole with soil or grass. Do not mix Postcrete with water by hand or machine.
