Application guidelines

Always apply Multi-Pave Outdoor Cleaner to dry tarmac, slabs, decking or resin driveways. Don’t apply if rain is forecast within the next 24 hours.

Standard application

Apply Multi-Pave 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 Multi-Pave may leave a white residue, but rainfall will gradually wash this away.

  • Step 1: Fill a 10 litre plastic watering can (fitted with a medium plastic rose) with cold water. Empty one sachet into the water and stir the solution 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 out the watering can and any other equipment with cold water.

Surfaces in poor condition

Follow these additional steps for areas with excessive surface algae or weeds / moss between joints.

  • Step 1: Apply first application of Multi-Pave. 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 Multi-Pave 4 weeks after the first. Multi-Pave will gradually break up the moss and debris between the joints and slowly disperse over time.

Results: Be patient

Allow rainfall to rinse your block paving and Block Blitz Multi-Pave will gradually start to transform your paving. Multi-Pave has a slow, secondary, cleaning effect which helps prevent the regrowth of algae and moss for months afterwards. It will also help clean jointing materials, helping to deter future weed growth. Any newly emerging weeds can be spot treated with a weed killing product. However, the more you use Multi-Pave, the more resistant the joints will become to weed growth.

NB: Multi-Pave Outdoor Cleaner will not restore the colour of weathered surfaces.
