How to Remove Concrete With Chemicals


Building anything out of concrete will make it last and stand the test of time. Being one of the most durable materials we have around, it makes perfect sense that we use it to anything from BBQ pits and garages to houses and skyscrapers. Things like rebar and steel can be added to the concrete to make it even stronger. Once the dust has settled and the job is complete you are left with a mess to clean up, and removing dried concrete is not as easy as it should be. This article will show you how to effectively remove concrete with the use of chemicals.

Things You'll Need

  • Hammer
  • Chisel
  • Sandpaper
  • Flo-Chem Concrete Off Plus Concrete Cleaner, Remover and Etcher
  • Pressure Sprayer
  • Mild Detergent
  • Hot Water

Removing Concrete

  • Dissolving large chunks of concrete is not an option so using a hammer, chisel away large chunks of the concrete to get closer to the surface you are trying to clean.

  • Use sandpaper in firm, strong vertical motion to remove bumps and ridges of excess concrete.

  • Clean the pressure sprayer thoroughly with hot water and mild detergent making sure it is dry before using.

  • Follow the manufacturer's instructions for using the Flo-Chem Concrete Off Plus Concrete Cleaner, Remover and Etcher and put it inside the pressure sprayer and apply a layer to the concrete you wish to remove for large surfaces.

  • Clean out the pressure sprayer again and fill with hot water and mild detergent and wash off the Flo-Chem once the alloted time as elapsed.

Tips & Warnings

  • For small jobs you can simply brush on the Flo-Chem.
  • Always remove as much excess concrete as possible before using chemicals.
  • It may be prudent if your job is large to have two pressure sprayers on hand.
  • Using any type of chemical can be dangerous and you should always wear protection.
