Repair of rough patches on the surface of a concrete garage floor
Q. I have several rough patches on my garage floor that I need to repair and then paint the floor with concrete garage finishing coat. What product should I use to repair these very rough surface only patches so that I can paint?
A. If you're going to repair the rough patches yourself, then I would recommend you use Quikrete's concrete resurfacer. You can purchase it at Home Depot.
It's very fluid after you mix it which makes it easy to apply. You can use a trowel or squeegee to apply it with. I would also purchase a rubbing stone while at HD.
After you trowel the resurfacer onto the rough spots, leave it a little higher than the existing concrete (1/16 inch is good). Leaving it high is much better than getting it low. Once the material is dry, you can sand it down with the rubbing stone to match the existing concrete floor.
Make sure you follow the manufactures specs. for surface prep and mixing instructions.
