TLDRIn this video, Mike from EverythingAboutConcrete.com demonstrates the step-by-step process of applying a high-quality epoxy coating to a garage floor. He covers essential preparation techniques, including grinding off old coatings, fixing cracks, and cleaning the concrete. Mike emphasizes the importance of using the right primer and epoxy products to ensure durability and prevent peeling. The video also highlights tips for applying the coating, rolling it evenly, and using a protective urethane top coat for a long-lasting finish. For those interested in DIY, Mike offers a detailed course to guide them through the entire process.

Takeaways

  • 😀 Proper surface preparation is crucial for a durable epoxy coating, including grinding off old epoxy or paint.
  • 😀 Using a grinder with a diamond blade and a vacuum attachment is an effective method for surface prep.
  • 😀 If a grinder isn't available, a diameter brush attached to a floor buffer can be rented as an alternative for prepping the concrete.
  • 😀 Always fix cracks and divots in the concrete before applying the epoxy coating to ensure a smooth surface.
  • 😀 Cleaning the concrete thoroughly, including wiping it down with denatured alcohol, ensures proper bonding of the epoxy.
  • 😀 Applying a primer before the epoxy coating helps block moisture from coming up through the concrete and causing peeling.
  • 😀 Epoxy coatings typically come in a two-part mix (A and B), and proper mixing is critical to ensure correct application.
  • 😀 Spread the mixed epoxy with a squeegee to ensure an even application across the floor before rolling it out with a paint roller.
  • 😀 Rolling the epoxy both ways (north-south and east-west) helps to achieve a uniform coat and eliminates streaks.
  • 😀 After applying the epoxy, a polyurethane or urethane topcoat is recommended for added durability and scratch resistance, extending the life of the floor.

Q & A

  • What is the first step in preparing a concrete floor for epoxy coating?

    -The first step is to grind the existing coating or paint off the floor using a hand grinder with a diamond blade. This ensures proper adhesion for the new coating.

  • Why is it important to grind off old coatings before applying a new epoxy floor?

    -Grinding off old coatings is necessary because it removes any contaminants and ensures the new epoxy will bond properly to the concrete, preventing peeling or blistering.

  • What tools are recommended for prepping the concrete floor?

    -Mike recommends using a hand grinder with a diamond blade or a floor buffer with a diamond grit pad for preparing the concrete. Both methods help clean and prep the surface for better bonding.

  • Can you use a floor buffer for prepping the concrete instead of a grinder?

    -Yes, you can use a floor buffer with a diamond grit pad to prep the concrete. It's effective, though hand grinders are preferred for removing old coatings.

  • What should you do if there are cracks or divots in the concrete?

    -You should fill in the cracks and divots with a patch repair material. After that, grind the repaired areas smooth to ensure a flat, even surface for the epoxy.

  • Why is it necessary to clean the floor thoroughly before applying the primer?

    -Cleaning the floor thoroughly is crucial to remove dust, dirt, or oils that could interfere with the bonding of the primer and the epoxy coating.

  • What is the purpose of the primer in the epoxy floor coating process?

    -The primer helps prepare the concrete for the epoxy coating by promoting adhesion and blocking moisture from rising through the concrete, which could cause the epoxy to peel or bubble.

  • How do you mix the epoxy for application, and why is it important to apply it quickly?

    -Epoxy is mixed by combining two components (a two-to-one ratio of A to B). It's important to apply it quickly because the mixture starts to heat up and set once combined, so getting it on the floor before it hardens is essential for proper coverage.

  • What is the correct method for applying the epoxy once it is mixed?

    -After mixing, pour the epoxy onto the floor and spread it out using a squeegee. Then back-roll the epoxy with a roller to ensure an even finish.

  • What is the role of the urethane topcoat in the process?

    -The urethane topcoat protects the epoxy layer by providing a hard, scratch-resistant finish. It helps extend the life of the floor coating and prevents damage from wear and tear.

  • What common problem does Mike mention with DIY epoxy kits from big-box stores?

    -Mike points out that DIY epoxy kits from big-box stores are often too thin and don't last well. They are prone to peeling and blistering, especially in areas like garage floors where tires frequently come into contact with the coating.

  • How long does it typically take for the primer to dry before applying the epoxy?

    -The primer typically takes about 3 to 4 hours to dry, but it can be left overnight to ensure it is fully cured before applying the epoxy.

  • How does the course Mike offers help those wanting to apply an epoxy floor themselves?

    -Mike's course provides a step-by-step guide, from preparing the concrete floor to applying the primer, epoxy, and topcoat. It also includes tips and tricks for achieving professional-quality results and avoiding common mistakes.
