Coloring concrete. ?
Thanks for the class and supporting Instructables and the do it yourselfers. I am going to be making a countertop for my home. I have a wet grinder and have made many practice molds/castings. My question is 2 parts
1. I am having trouble getting a good gray color from standard 5000psi bag mixes and one type of countertop bag mix. The 5000psi mixes have a gray/green color. Hard to explain. And the countertop mix is pretty ashy. Do you have suggestions on a mix, or do I need to buy a gray coloring from Mr. Roads or Mr. Chang.
2. I want to have the glasslike polished look to my countertop but without exposing agraget (if I can). Do I start with 400grit diamond pads and move up? Is there another method to polishing that I am just oblivious to?
Thanks again for the class. Sorry for the long message. Looking forward to lesson 4 tomorrow.
