Industrial floors, parking lots, garages, and other concrete surfaces require painting. However, painting is not just to lend freshness to the premises. In fact, it may be necessary to demarcate parking lots, post warning signs or instructions or color code different areas for operational requirements, to name a few, which can be achieved through painting.
However, painting concrete floors is not simply a matter of taking up paint and applying paint with a brush. Concrete has special characteristics that require special treatment. For a long-lasting and effective job it has to be done in a systematic and professional manner.
Tools and Materials RequiredConcrete Paint

  • Paint: For best results, use hybrid organic or organic nano-lithium paint that comes with high solids and lithium-silicate water-based formulation that ensures high performance. This not only gives a strong matte finish, but also contributes to protecting the floor effectively.
  • Primer: If you don’t prime then you run the risk of the paint peeling, especially since garage floors are so smooth.
  • Concrete cleaner: Solution that will remove extra-tough dirt and grime from asphalt, glazed or unglazed ceramic tile and concrete
  • Concrete sealer: When the concrete floor has a stain applied, it is important to seal the floor to preserve the color.
  • Water: Use water as the final rinse after using the cleaner.
  • Paintbrush roller or pump sprayer: Optional equipment to apply paint to concrete floor.

The Concrete Floor Painting Process

  1. Clean the floor thoroughly: Use a vacuum to suck out dust and debris. Painting atop dust and debris will erode large chunks of the paint away from the surface very quickly.
  2. Apply concrete cleaner: Use a concrete cleaner to clean the floor. Wet the floor, apply the concrete cleaner solution and rinse it away with more water. Allow the floor to dry.
  3. Apply concrete sealer: Using a paintbrush roller, apply two to three coats of concrete sealer to prevent moisture seepage through the floor. Moisture can ruin the paint job. Make sure that the sealer cures thoroughly before applying a fresh layer. This can take many days.
  4. Apply concrete primer: Once the surface is dry, apply concrete primer using the paintbrush roller. Apply the primer in even strokes, especially filling any small gaps or voids in the floor to ensure a smooth appearance.
  5. Apply the paint: Paint the surface as required, using a paintbrush roller or pump sprayer. For special markings and words, either place the stencil cutting on the floor and spray above the cutting, or simply use a paintbrush to paint the required text or sign.
  6. Apply multiple coats: When applying multiple coats, let the paint dry for about 24 hours between coats.

This is a DIY task, and can be done well, once you understand the process involved, and make sure to be well prepared before starting the task. A little preparation, the right tools, care, and patience will ensure you do a perfect paint job.
