Questions About Stamped Concrete

by Ethan Schneider

The CTI tech department often receives calls from dealers about going over, repairing, re-coloring, re-sealing or all of the above in reference to stamped concrete.

While each situation is different there are some common similarities. In general working on pre-existing stamped concrete jobs involves a number of unknown circumstances. We don’t know what kind of grout products, color pigments, color release agents, mold release agent, sealers etc. Keeping that in mind we don’t know how our CTI products are going to react or perform. Therefore, we can not guarantee anything. Many CTI dealers do in fact try to help customers with existing stamped concrete finishes but it is very important that the customer understands that there is no guarantee.

If you decide to work on one of these projects it is highly recommended that you first test out your procedure on a small inconspicuous area before attempting to do the entire job. If there are any sealers on the job it is best to try and remove them before you start. Sandblasting or using a Sandcat attached to your power washer usually will remove the sealer from the lower portions of the stamp. It is best to handle the jobs on a case by case basis. You can submit pictures to the CTI tech department for opinions before proceeding or even quoting the job. We are not saying that you shouldn’t do these kinds of jobs. We are saying that you should proceed with caution and seek technical advice as needed.
