Written by Travis McCutchen | Sep 4, 2024 12:00:00 PM

Concrete is a durable and versatile material that is commonly used for building structures, pavements, and other outdoor surfaces. However, over time, concrete floors can become dull and worn out from exposure to weather elements and heavy foot traffic. This is where sealers and dyes come in – they help protect the surface of concrete while enhancing its appearance.

In this guide, we will discuss how to properly apply concrete sealer and dye concrete to achieve a beautiful and long-lasting finish.

The Importance of Concrete Sealing and Dyeing

Concrete sealing and dyeing are about more than just aesthetics. Sealing protects the surface from stains, moisture, and wear, while dyeing adds color and vibrancy. Properly treated concrete can transform dull, gray surfaces into stunning focal points, making them ideal for both residential and commercial spaces.

Understanding the Basics of Concrete Sealing


Why Seal Concrete?

Sealing concrete is crucial for protecting it from damage caused by water, chemicals, and everyday wear and tear. Without a sealer, a concrete surface is prone to cracking, staining, and deterioration. A good sealer acts as a barrier, prolonging the life of the concrete floor and maintaining its appearance.

Types of Sealers

There are three main types of concrete sealers:

Film-Forming Sealers

Film-forming sealers create a protective layer on the surface of the concrete. They are great for enhancing color and providing a glossy finish. However, they can be slippery when wet and may require reapplication more frequently.

Penetrating Sealers

These sealers penetrate the concrete to form a chemical barrier. A penetrating sealer is excellent for protecting against water and stains without altering the appearance of the surface. Penetrating sealers are ideal for exterior concrete such as concrete driveways.

Topical Sealers

Topical sealers are applied directly to the surface and can be either water-based or solvent-based. They provide a durable finish but might need periodic maintenance to retain their effectiveness.

 

Advantages and Disadvantages of Each Type

Film-Forming Sealers

  • Advantages: Enhances color and provides a glossy finish.
  • Disadvantages: Slippery when wet, requires frequent reapplication.

Penetrating Sealers

  • Advantages: Long-lasting protection, maintains a natural appearance.
  • Disadvantages: Limited color enhancement might be less effective on very porous surfaces.

Topical Sealers

  • Advantages: Durable finish, various finish options.
  • Disadvantages: Needs regular maintenance, and can alter the appearance.

The Art and Science of Concrete Dyeing


of Concrete Dyeing

Concrete dyeing is a popular decorative option that can transform plain concrete into a vibrant, colorful surface. Unlike paints or coatings, dyes penetrate the concrete, creating a more natural and permanent color. Concrete dyes are available in an array of colors, allowing endless customization.

Types of Dyes

Water-Based Dyes

These are easy to apply and clean up, making them a popular choice for DIY projects. They offer a range of colors and are environmentally friendly.

Solvent-Based Dyes

Solvent-based dyes provide intense, vibrant colors that are ideal for high-traffic areas. They dry quickly but require proper ventilation during application due to strong odors.

Acetone Dyes

Acetone dyes are known for their fast-drying properties and deep penetration. They offer a wide range of colors and are suitable for both indoor and outdoor use.

Factors to Consider When Choosing the Right Dye

When selecting a dye for your project, consider the following factors:

  • Location: Indoor or outdoor use will dictate the type of dye you should use.
  • Desired Color: Different dyes offer various color intensities and hues.
  • Application Method: Some dyes are easier to apply than others, depending on your experience level.
  • Environmental Impact: Water-based dyes are more eco-friendly compared to solvent-based options.


Step-by-Step Guide for Sealing and Dyeing Concrete

Now that we have covered the basics, let's dive into a step-by-step guide on how to seal concrete and apply dye.

 

Materials Needed:

  • Concrete sealer of your choice
  • Concrete dye in preferred color(s)
  • Pump sprayer or roller for applying sealer
  • Paint brushes for detail work
  • Floor scrubber or sander (optional for surface preparation)

 

Sealing Process:

  • Clean the surface thoroughly with water and mild detergent to remove any dirt, stains, or debris.
  • If necessary, take advantage of Onfloor's quick change tooling by attaching a floor scrubber or sander to your Onfloor machine to smooth out rough spots or imperfections
  • Allow the surface to dry completely before applying the sealer.
  • Using a pump sprayer or roller, apply the sealer evenly across the entire surface. Be sure to follow the manufacturer's instructions for application and drying times.
  • If desired, add another coat of sealer once the first coat has dried.

 

Dyeing Process:

  • Once the sealer has fully cured, clean the surface again with water and mild detergent to remove any residue from the sealing.
  • Allow the surface to dry completely before applying the dye.
  • Create your desired color by mixing different dyes together. Test the color on a small area before applying it to the entire surface.
  • Using a pump sprayer, apply the dye evenly across the surface.
  • For more intricate designs, use paintbrushes to create patterns or add additional layers of color.
  • Allow the dye to dry completely before adding a sealant layer for extra protection and shine.
  • Once the sealant has cured, your concrete is ready to be used and enjoyed!

Do You Seal or Dye First?

It is recommended to seal the concrete first, as this will protect it from any potential damage caused by the dyeing process. Additionally, sealing first allows for easier clean-up in case there are any spills or mistakes during the dyeing process.

However, if you are using a water-based dye, it is possible to dye first and then apply a sealer on top once the dye has dried. It is important to follow the manufacturer's instructions for both the sealer and dye to ensure proper application. So, it ultimately depends on your personal preference and the type of products being used.

Safety Precautions and Environmental Considerations

While sealing and dyeing concrete is generally a safe and straightforward process, it’s essential to take proper precautions to protect yourself and the environment. Here are some safety tips to keep in mind:
