Key Differences of Epoxyshield Vs. Rocksolid Coatings

Epoxyshield and Rocksolid are two of the most popular options on the market.

While both coatings provide a durable and long-lasting finish, there are some key differences to consider before deciding.

Colors & Finishes

One of the biggest differences between Epoxyshield and Rocksolid is the range of colors and finishes available.

When you use Rocksolid to coat your garage floor, you can expect a solid base color with a stunning color-fleck finish that dries to a glossy shine.

It also offers various colors, including gray, tan, black, modern garage, and mocha.

Expoxyshield has a more limited color selection.

It may not offer the same level of shine as Rocksolid, but it still gives your garage a unique and textured finish that gives a professional look.


While both coatings are DIY-friendly, the application process differs slightly.

Because Epoxyshield is a two-component water-based coating, you must mix an activator and a base, which can take 2-3 minutes.

Rocksolid, on the other hand, only requires one coat of Polycuramine coating.

Thus, the application process is quicker and easier.

Regarding curing time, Rocksolid is also quicker, requiring 10 hours to dry to resume foot traffic and 36 hours for vehicles.

Epoxyshield takes 16 hours to 48 hours of drying time.

Lifespan & Durability

When it comes to lifespan and durability, both coatings are top performers.

However, Rocksolid has a slightly longer lifespan and is more resistant to scratches and scuffs.

Epoxyshield, on the other hand, is more resistant to chemicals and stains.

Ultimately, the lifespan and durability of each coating will depend on how well you maintain your garage floor.


The cost of the coatings is another important factor to consider.

Epoxyshield is generally more affordable than Rocksolid, making it an excellent option for those on a budget.

However, Rocksolid's longer lifespan and durability may make it a better long-term investment.


Both coatings are not recommended for use on floors with moisture issues as well as surfaces that have been previously coated with bonded paint.

Additionally, both coatings require a clean and smooth surface for proper adhesion.

Epoxyshield Vs. Rocksolid Coatings: Professional or DIY Installation

When it comes to installing garage floor coatings, you have two options: professional installation or DIY installation.

Both Epoxyshield and Rocksolid coatings are designed for DIY installation, but there are some differences to consider.

Pouring garage flooring coating in the garage floor

Epoxyshield coatings are relatively easy to install, but they require a bit of preparation.

You need to clean the surface thoroughly and ensure it's completely dry before applying the coating.

You also need to mix the two components of the coating together before applying it.

Rocksolid coatings, on the other hand, are even easier to install than Epoxyshield coatings.

They come in a single can, so you don't need to mix anything together.

You need to apply the coating to the surface and let it dry, making it an excellent option for those new to DIY projects.

If you're comfortable with DIY and have some experience with home improvement, either coating should be easy enough to install on your own.

The Verdict: Which is Better - Epoxyshield or Rocksolid Coatings?

When it comes to choosing between Epoxyshield and Rocksolid coatings, it ultimately depends on your specific needs and preferences.

Both coatings have pros and cons, and it's up to you to decide which is better for your garage floor.

If you prioritize affordability and stain resistance, then choose Epoxyshield.

On the other hand, if you need a coating that's highly resistant to chemicals with a long-lasting coat, opt for Rocksolid.

With a 96% solids content by volume, it's a highly durable and flexible coating that can withstand heavy use and abuse.
