Application guidelines

Always apply Block Blitz to dry gravel or aggregate paths and driveways. Don’t apply if rain is forecast within the next 24 hours.

Standard application

Apply Block Blitz every 5-6 months, at any time of the year.

NB: Before use, it’s advisable to test a small inconspicuous area of the surface to be treated to check for suitability. Block Blitz  gravel cleaner may leave a white residue, but rainfall will gradually wash this away.

  • Step 1: Fill the watering can provided with 10 litres of cold water. Empty one sachet into the water and stir the solution with the wand until fully dissolved.
  • Step 2: Start applying at the highest point to control excessive run off that could damage grass and plants. Apply evenly to soak the surface area.
  • Step 3: Leave to dry. Rinse the watering can, rose and stirring wand with cold water.

Gravel in poor condition

Follow these additional steps for areas with excessive surface algae, weeds or moss.

  • Step 1: Apply first application of Block Blitz. Leave to work for a minimum of two weeks.
  • Step 2: Spot treat any remaining weed growth with weed killing product.
  • Step 3: Apply second treatment of Block Blitz 4 weeks after the first. Block Blitz will gradually break up the moss and debris and slowly disperse over time.

Results: Be patient

Allow rainfall to rinse your gravel and Block Blitz will gradually start to transform your path or drive. Block Blitz has a slow, secondary, cleaning effect which helps prevent the regrowth of algae and moss for months afterwards. It will also help  deter future weed growth. Any newly emerging weeds can be spot treated with a weed killing product. However, the more you use Block Blitz, the more resistant your paths will become to weed growth.

NB: Block Blitz will not restore the colour of weathered aggregates.
