Concrete Dyes Or Acid Stains

Most people think of acid when they think of stained concrete, but there are alternatives. The big question, though, which one is better, acid stains or dyes? That proves to be the million dollar question. The simple answer is neither! Both types of stains are great and effective in achieving beautifully stained concrete surfaces.

The chemical makeup is what makes them different. Acid Stains for concrete are a mixture of water, salts and acid that are applied to the concrete surface. They react chemically with the mineral content and excess lime in the concrete surface for a permanent stain. Acid stains are UV stable when sealed with an appropriate sealer and can be used on both interior and exterior applications. Green and blue stains are typically for interior use only. Acid stains create a variegated or mottled appearance that is unique to each individual concrete slab. The depth of the colors penetration ranges from 1/16 to 1/32 of an inch.

Exterior concrete surfaces usually do not color as well as interior surfaces because the environment has leached or percolated out most of the mineral content. Exposed aggregate (rocks) in worn concrete will not accept staining unless they’ve been ground down with a concrete grinder.

Concrete Dyes are a translucent solution, usually based in alcohol or solvent and formulated using very fine particles of color designed to penetrate and color interior or exterior concrete surfaces, including polished concrete. Some dyes are UV stable. Concrete Dyes create a unique, multi-colored translucent color scheme that unlike paints, will not crack, chip, or peel. Concrete Dyes come in many different colors and can be combined to create an unlimited color palate that creates a similar mottling or marbleized effect as acid stains. Exposed aggregate in worn concrete will accept color to varying degrees.

Concrete dyes and concrete acid stains can be used in conjunction with each other. Some manufactures even recommend having a corresponding dye available when staining in order to dye areas that may not take acid stain well. Using dyes together with stains in this application lends to a more consistent and uniform color in the floor. Dyes and stains can be used to accent each other, increasing the color pallet that is limited by acid stains alone.

There are some down sides to both type stains. Acid stains are typically very dependent on the concrete and the reaction that is achieved upon application and have a limited color pallet . High levels of fly ash will effect the color adversely. Acid staining is not a good candidate for concrete that has been sealed. Often times it is recommended that the surface be ground to help remove the sealer.

While this does help, it also removes the fines that the acid stain needs to react with to achieve the desired color. Most often the colors come out muted and much lighter than expected. Acid staining is a very wet application when done correctly and is not always a good fit.

Concrete dyes also have some down sides as well. Concrete dyes will penetrate very quickly and they leave little room for error when applying. The porosity of the concrete plays a large part in the penetration of concrete dyes, especially when using solvent based dyes. A surface that is very porous can have color fallout. This is where the small molecular size of the dye may penetrate too far into the slab and you lose the color all together. Typically densifying the slab and reapplying will fix this issue.

If a slab is too tightly finished, the stain may sit on the surface and not penetrate enough causing the stain to rub off during the cleaning phase of application. A simple fix for this is a light acid wash or grinding of the surface to open up the slab.
