What Do You Spray on Concrete Before Pressure Washing?

Pre-treating Concrete for Pressure Washing

Here’s a quick overview of options you can spray before cleaning:

  • Dish Soap or Detergent – for small amounts of grease
  • Concrete cleaner or Degreaser – for large cleaning projects, can tackle oil and grease.

Keep a distance of 6 inches from the surface while spraying concrete with a bottle of degreaser. Scrub the degreaser into concrete using a stiff brush or pressure-washer attachment. Prepare the area by clearing loose material off the driveway before applying a degreaser to loosen stains in the concrete.

Choosing the Right Cleaner for Concrete Pressure Washing

Pre-treating your concrete before pressure washing ensures a more efficient cleaning process by breaking down stains and grime. Properly pre-treating your concrete surfaces with the right cleaner will pave the way for a successful pressure-washing endeavor. Common cleaners for concrete include degreasers, all-purpose cleaners, acid-based cleaners, and enzymatic cleaners. It’s important to choose a cleaner based on the stains or dirt present.

Pressure Washing Concrete Surfaces

Spray down the concrete with a hose before using the pressure washer to remove any loose debris or dirt. Avoid using an acid-based solution on a concrete surface as this can cause damage. Opt for an alkaline-based cleaner specifically designed for concrete surfaces before pressure washing.

  • Ensure durability when choosing the best chemicals for pressure washing concrete, especially for colored or stamped concrete.

Tips for Effective Pressure Washing

Use a fan nozzle when cleaning concrete for a wider spray pattern that covers a larger area at once, distributing water pressure evenly and reducing the risk of surface damage.
