Concrete Stain, Dye and Seal
Mile High Coatings can give you a totally unique, custom look to your concrete through concrete acid stain. This process involves using a mild acid with color to induce a chemical reaction in your concrete that results in magnificent permanently colored concrete. Concrete staining is ideal for basements and commercial spaces and also great for outdoor patios! The possibilities are endless!
The key to the perfect looking stained concrete floor is the quality of our sealers and our industry-leading preparation. We only use the highest quality prep equipment and materials. We prepare the concrete surface using our concrete diamond grinder to get the floor smooth and clean. Then we apply our proprietary dye/stain and seal it with our SHP Polyaspartic clear coat. The benefit is that you get the aesthetic beauty and appearance of an acid stained floor with the performance of an industrial-grade coating.
For outdoor patios and walkways, we can add a traction additive to our clear coat to ensure a non-slip surface. This allows you to have a beautiful stained concrete area with the durability of the SHP Polyaspartic. Crack repairs, spalling (pits, divots, holes, etc) repairs or other patching can be completed. However, sometimes leaving the flaws alone will often add to the character of your floor.
Removal of existing coatings, sealers, carpet glue or mastic is generally not a problem. Our professional equipment and experience will make sure that the concrete is suitable and clean before we apply any stain and/or sealers.
Being upfront, honest and acting with integrity is a fundamental reason why Mile High Coatings is among the best concrete stain companies in Fort Collins & Northern Colorado. The vast majority of our work comes from repeat customers and word of mouth referrals.

Concrete Acid Staining Application
Acid staining concrete is a bit of an art. Mile High Coatings has the experience to safely apply a wide variety of custom concrete effects with minimal environmental impact.
Clean, unsealed concrete is a must for an acid stain to properly react with the calcium and lime in the concrete. After the reaction is complete, it needs to be carefully neutralized and cleaned up. The complete unique, one-of-a-kind results that you get from acid stains are what make this application appealing. Once the floor is clean and dry, we can seal the floor. Depending on the area you’re finishing (could be a basement, office space, or patio), we have some options for sealing the concrete and give your new floor the desired sheen and finish that you want.

What is Acid Stain?
An acid stain is salts or a combination of salts that are carried by acid, typically hydrochloric acid, to help facilitate a chemical reaction with the calcium and lime in the cream of the concrete, which is the top layer. An example that many homeowners are familiar with: the rust spots on your sidewalk or driveway from fertilizing the yard. It’s the same principle. The iron turns to iron oxide (rust) and permanently dis-colors the concrete. The same is true with an acid stain – the color is permanent. Although it’s strongly suggested, it theoretically doesn’t need to be sealed.

Metallic Epoxy Flooring
Another fun (growing in popularity) alternative application we can do is create a metallic epoxy floor. This unique, marble-looking floor coating is not a concrete stain but it’s not your typical epoxy floor, either.

This application involves thorough diamond grind preparation, a primer coat and a thick application of a metallic epoxy coating that will settle, flow and move to its own pattern. These floors definitely inspire the WOW response from visitors to your home!
An optional recommended clear coat can be applied on top to help the epoxy keep its shine and appearance.
These floors can even be installed on wood substrates such as the subfloor in your home. Because of the thickness, it can act like an insulator and it reduces and practically eliminates radon passage through the floor. Additionally, this is a very low odor and potentially Zero-VOC application.

F.A.Q
I have drywall mud OR carpet glue OR paint on my concrete floor. Do you clean the floor before staining it?
Yes. We either clean it very well prior to applying an acid stain. If we are using the dye (also a stain), we will diamond grind the floor, which cleans and profiles the concrete prior to staining and sealing.
Will you remove my old carpet or tile floor?
Yes! We are happy to remove and dispose of any old or existing flooring you have.
Do you repair cracks in my patio or basement floor?
With stained concrete, many times we leave the cracks alone and chalk it up to "character." However, if it is wide or deep, we can certainly repair it. It's totally up to the customer if they want it filled in or not.
Does the coating smell?
It depends. We have low or no-odor options. These are typically high-solids content coatings or water-based coatings. We also (mostly) use solvent-based coatings that do smell. For basements, we can provide and set up a fan in a window or doorway to help facilitate airflow to help alleviate the smell during the curing and out-gassing process. And, it's a good way to chase off any spiders you may have lurking in the basement!
Do you have samples of the stained concrete?
We provide samples, when possible, on the slab to be stained. This is because every slab is unique with finish, color, etc. Plus, concrete samples would be really heavy and we don't want our salesmen's muscles to get too big.
