Project Overview

Algae and mould grow prolifically in the tropics because of wet season weather conditions. They can grow on your driveway and walkways, which become slippery and dangerous. With the right products and some know-how from us, getting rid of them is easy.

Step by Step Instructions

1 Sweep the driveway
2 Spray the chemical cleaner on the driveway
3 High-pressure clean the driveway
  • Step 1. Sweep the driveway

    Before you start cleaning the driveway, use a broom to sweep away any leaves and debris. This will stop patches forming where the cleaner wasn’t sprayed on the driveway.

  • Step 2. Spray the chemical cleaner on the driveway

    Before you start spraying the chemical cleaner, carefully read the instructions on the package. Put on your safety glasses and protective gloves. Starting at the bottom of the driveway, begin spraying the chemical cleaner onto it. Work your way to the top of the driveway spraying all over it with the cleaner. 

  • Step 3. High-pressure clean the driveway

    Change the nozzle on the high-pressure water cleaner to the patio cleaning nozzle. Connect the high-pressure cleaner to the garden hose. Start at the top of the driveway and slowly sweep your way across and down the entire driveway with the high-pressure cleaner. Depending on the size of the driveway, this might take some time but it’s a job that shouldn’t be rushed.
