Thank you so much, Shea! I really appreciate your advice and will give them a call tomorrow.

Hi Karl. Penetrating sealers are non-film-forming. TSP won’t do anything to remove the sealer if that’s what you are thinking. However, it is an excellent concrete cleaner and a good choice to use. We would recommend renting a floor maintainer from your local home improvement center and purchasing a couple green or black scrub pads to do the hard work. Because you used a penetrating sealer and the floor will absorb water, we believe you would be OK using TS210. If it was any other type of coating, such as epoxy, you would need to grind the surface to remove the sealer. We would recommend thinning the first coat to act as a primer as it states in the instructions. Apply two thin coats after that. Before you decide to purchase it though, call Concrete Sealers USA first. Tell them we sent you. Give them the info on your concrete and what you plan to do. They will be your best source of information.

Hi Dan. We would recommend TS210 first based on your requirements. It would be the easiest to apply, it’s more budget friendly, and will perform well for the type of use you have planned for the space.

Hi Michael. The color will get lighter when you apply a lighter stain over darker concrete. However, stains are translucent and the darker undertones of the concrete will still come through. Once a stain is applied, you can only go darker in color, not lighter. That is why when multiple colors are used, the lightest color is applied first. In addition, stains highlight all the imperfections in the concrete and give it character. If you don’t care for that, the only way you can a achieve a solid lighter color is to apply a colored coating.
