A:  Hi JJome, thank you for your question. To prepare uncoated concrete, we recommend etching the surface if it feels smoother than 150 grit sandpaper. That will ensure it has the correct texture for the Solid Color Concrete Stain to adhere. Then, make sure the surface is clean and dry. For the best performance, prime the floor with our Concrete & Masonry Bonding Primer (No. 880) before staining. Best of luck with your project! -Lina
