How to Clean, Paint, and Polish Concrete

So you’ve got concrete? Lucky you.

Concrete isn’t just for pavements and driveways anymore. It’s the unsung hero of patios, garages, basements, and even posh indoor floors. But, even the toughest surfaces need a little TLC.

Let’s dive into the three concrete commandments: clean it, paint it, and polish it.

Step 1: Cleaning Concrete

First things first: you’ve got to clean your concrete.

• Sweep it: Get rid of loose debris, leaves, or that weird mystery gunk with a quick sweep over
• Hose it down: A good rinse works wonders and ideally you’ll use a pressure washer.
• Try this homemade potion: Warm water, dish soap, and a sprinkle of baking soda. For those oil stains, use a degreaser and let it sit before scrubbing.
• Mould or mildew? Use a bleach-and-water mix (1:10 ratio).

Pro tip: If your concrete starts foaming, you’re doing it right.

Step 2: How to Paint Concrete

Take your concrete to the next level with a coat of paint:

• Start with clean, dry concrete: Remember Step 1? This is why it matters.
• Etch it: Use a concrete etching solution to open up the surface.
• Apply a concrete primer: This will help the paint stick better.
• Choose your paint wisely: Go for masonry paint or epoxy-based paint. Avoid acrylic.
• Apply with a roller: Use a paint roller and take your time. Two thin coats are better than one thick one that won’t dry properly.

Step 3: How to Polish Concrete

Simple steps to polish your concrete floor:

• Grind it down: Use a concrete grinder with a coarse diamond pad. This removes the top layer and any lingering imperfections.
• Keep grinding: Switch to finer grit pads as you go.
• Apply a densifier: This hardens the surface and makes it ready to shine.
• Polish to perfection: Use a polishing pad to bring out that glossy finish. You’ll know you’re done when you can see your face in it!

Pro Tip: Seal it to lock in the shine and keep stains out.
