We instructed the concrete finisher to finish the floor very smooth all the way to the walls so we can stain the floor. He did a lousy job and we are now working on fixing the problem. We will try a concrete grinder in hope that it will result in a smooth, stainable surface, but the different chemical compositions of the different pours may be a problem. We may also have to consider a complete new coat, possibly with a product like Permacrete. (We would appreciate any information or ideas anyone has to solve the problem.)









The subcontractor did such a bad job that they also covered completely over nearly all the drains with up to 3/4" of concrete. The drains all had to be chipped out and the drainage will need to be redone.
