Direct Colors Concrete Acid Stains are designed to enhance the appearance of concrete and other surface materials. It has been proven in thousands of commercial and residential applications to create a beautiful and unique flooring surface.
Acid Stains produce unusual and permanent color effects in concrete, self-leveling topping systems, gunite, cement plaster, stucco, shotcrete, natural stone marble, cultured stone, limestone and other surfaces.
Each concrete acid stain creates uneven color effects that simulate the natural shadings and aged appearance of stone or masonry. The color effect is unique to each stained surface and cannot be duplicated with other materials.
COMPOSITION & MATERIALS
Direct Colors Concrete Acid Stains are composed of a unique formulation of blended metallic salts in an acidic water-based solution. These metallic salts penetrate and react with the chemical substance in the concrete to deposit the colors into the concrete pores. Each color is composed of a complex proprietary formulation that contains no pigments or resins. When highlighted with the proper sealer, this effect provides a natural, attractive glow.
Direct Colors Concrete Acid Stains are available in 1 qt (0.95 L), 1 gal (3.8 L), 5 gal (18.9 L) and 55 gal (208 L) containers.
Depending on surface conditions, 400 sq. ft. applying one coat and 200 sq. ft. applying two coats.

REMEMBER TO PREP BEFORE STAINING!
Direct Colors Concrete Acid Stains are available in 10 standard colors (see Color Chart)
As a translucent product, the overall effects of the stain system leave an element of unpredictability as to the final appearance and effects of the applied stain. For this reason, the color chart is to be used as a guideline only.
Testing small areas or samples prior to job application is always recommended since the final color may differ significantly from what is shown on the chart. The difference is due to a number of factors, including, but not limited to, the age of the existing slab, mix design, finishing techniques, concrete base colors and surface permeability.
Acid stain can be diluted with water to lower the ratio of minerals, thus making the color lighter in shade. The best option is to test patch the concrete using straight stain and stain that has been diluted to 2 – 3 parts water to 1 part stain.
If the water content is will not facilitate the chemical reaction required to make the color. This can be corrected by raising the acid content or using stain extender.
Some colors vary more by adding water, but many factors, including age of the concrete, cement content and weathering determine how light or dark the stain will appear. This is another reason to conduct as many pre-stain tests as the jobsite will allow. During the application process, concrete acid stains can be blended together on the concrete slab at full strength or diluted to achieve beautiful marbling effects with diverse high and low lights.
Different stains require varying amounts of time to activate and fully color the concrete, generally from 2 – 8 hours. See Table 1 for details. Be sure to check stain activation time before starting the job to ensure full surface coloring.
For the most color from a given stain, spray another coat over the dried residue.
