Hi AVP26, thank you for your review. I'm sorry that the color did not turn out as expected and that the coating does not wash well. I assure you this is not the experience we want for our customers. Typically, cleaning the surface with a concrete/degreaser or soap and water helps remove stains. If that does not help, to fix your project, scuff sand the smooth or glossy surface, remove the dust, or clean the area; when dry, apply another coat. The new coat can be in a different color choice if the one used did not turn out as expected. Customer satisfaction is important to us, and we want to help. Please reach out to our customer care team directly for further assistance. They are always happy to help! -Alex
