How To Paint Concrete

Painting concrete isn’t just about enhancing aesthetics; it’s a crucial step in protecting and preserving your concrete surfaces. At APMG Painting, we’ve been transforming concrete surfaces across Melbourne for years, bringing over a century of combined professional painting experience to every project. Whether you’re looking to revamp your concrete patio, freshen up a commercial floor, or protect an industrial surface, our expert team is here to guide you through the process.

 

Preparing Concrete for Painting

1.    Moisture Check

Concrete is porous and can retain moisture, which can spell disaster for your paint job if not addressed. We always start by:

  • Using a moisture metre to test the concrete surface
  • If a moisture metre isn’t available, we employ the plastic bag test: taping a clear plastic bag to the concrete and checking for condensation after 24 hours

If moisture is present, we’ll recommend appropriate measures to dry and seal the concrete before proceeding with painting.

2. Surface Preparation

This step is critical for achieving a smooth, even finish that will last:

  • Stripping Old Paint: For previously painted surfaces, we use wire brushes and scrapers to remove any loose, peeling, or bubbling paint.
  • Patching Damaged Areas: We carefully fill any cracks, holes, or gouges with a suitable concrete filler, ensuring a uniform surface.
  • Cleaning the Surface: Using trisodium phosphate (TSP) and high-pressure washing, we thoroughly clean the concrete to remove any dirt, grease, or contaminants that could interfere with paint adhesion.

3. Masking and Priming

Once the surface is clean and dry:

  • We meticulously mask off surrounding areas with painter’s tape to ensure clean lines and protect adjacent surfaces.
  • We apply a high-quality primer suitable for concrete. For areas prone to heavy wear, we often recommend an epoxy primer for its durability and excellent adhesion properties.

By following these crucial preparation steps, we set the stage for a flawless paint application that will not only look great but stand the test of time.

The Painting Process

With thorough preparation complete, we’re ready to transform your concrete surface. At APMG Painting, we approach this stage with the same level of care and expertise that has earned us recognition as registered Master Painters and Dulux Accredited Painters.

Choosing the Right Paint

Selecting the appropriate paint is crucial for achieving a durable, long-lasting finish:

  • For most concrete surfaces, we recommend high-quality masonry paint. Its binding properties offer excellent durability and resistance to weathering.
  • For areas susceptible to water damage, such as exterior surfaces, we use paints with enhanced waterproofing capabilities.
  • In commercial or industrial settings, we may suggest specialised concrete floor paints designed to withstand heavy foot traffic or chemical exposure.

Painting Techniques

Our skilled painters employ proven techniques to ensure even coverage and a professional finish:

  • We begin by painting the perimeter of the concrete surface using a medium brush. This provides precise coverage in corners and edges.
  • For larger areas, we use paint rollers. We select the appropriate nap length based on the concrete’s texture – short-nap for smooth surfaces and long-nap for rougher textures.
  • When painting floors, we always start from the farthest corner and work our way towards the exit to avoid trapping ourselves.

Applying Multiple Coats

A flawless finish often requires multiple coats:

  • We allow each coat to dry completely, following the manufacturer’s recommended drying times.
  • Between coats, we inspect the surface, using a putty knife to smooth out any imperfections and lightly sanding if necessary.
  • The final topcoat is applied with extra care, ensuring full coverage and a uniform appearance.

Aftercare and Maintenance

To keep your freshly painted concrete surface in top condition, we recommend allowing sufficient drying time—usually 24-48 hours for foot traffic and up to 72 hours for vehicle traffic on painted garage floors. Our team meticulously removes all painter’s tape to reveal sharp, clean lines. We also offer advice on long-term care, including proper cleaning techniques and touch-up strategies to maintain the paint’s appearance over time.

FAQs

Q: Can you paint directly onto concrete? A: Yes, as long as the concrete is properly cleaned, repaired, and primed. However, it’s crucial to ensure the concrete is free from moisture and existing sealers.

Q: How long does it take for concrete paint to dry? A: Drying times can vary, but most concrete paints take 12-24 hours to dry completely. Always follow the manufacturer’s instructions and avoid foot traffic until fully dry.

Q: Can I paint over old concrete paint? A: If the existing paint is in good condition, you can paint over it. However, any loose or peeling paint must be removed first to ensure proper adhesion of the new coat.

Painting concrete is a transformative process that can dramatically enhance the appearance and longevity of your concrete surfaces.
