Acid Stain

Characteristics of a Concrete Acid Stain

When choosing acid stain as a color choice and finish for concrete it is necessary to be educated on its limitations. The end user should be made aware that the basic principles which make acid staining so beautifully mottled, variegated and marbleized can also cause some undesirable results.

Un-reacted Acid Stain in its packaging is often a translucent color that does not represent the final color that the concrete surface will become after the reaction and finishing takes place. Many tan and amber Acid Stain colors come out of the package a light green color. The final color will not be evident until the Stain has completely reacted with the cement substrate. The reaction takes place over a period of 1-8 hours (depending on the manufacturer). The stain brings out the natural variations found in Concrete but also may expose man-made blemishes and imperfections.

Acid Stains add translucent colors to the concrete surface and do not hide imperfections. Any undesirable blemishes or imperfections should be addressed prior to stain application. A qualified professional should be able to determine which ones may be of concern and their remediation.

No matter how discolored the concrete, many blemishes or variations will only add to the character of the finished floor. Application hazards and variations in the surface generally blend in or simply add to the variegated look and feel desired when choosing the natural marbling effect of concrete stain.
