Acid Staining Concrete / Cement Floors - Preparation and Cleaning.
After purchasing your supplies for acid staining your cement floors, you are ready to start. The first thing you will want to do is protect anything that you do not want acid or floor sealer on. On new construction where the walls are not painted or not up yet this is not necessary but on existing homes it is necessary.
Take the painters tape and butcher paper and tape off the baseboards and wall to about 12 inches off the ground. Use a minimal amount of tape on the walls just in case the tape tries to pull a layer of paint off. Painters tape should not do this but use as little as possible anyway.
Once the area is taped off simply sprinkle a little Tri Sodium Phosphate (TSP) on the floor, pour on some water and start up the buffer. (pictures of TSP and buffer at bottom of page) It takes a little while to get used to the buffer but after a few minutes you will be a pro. Make sure you are in the middle of the room the first time you squeeze the trigger on the buffer. Control side to side movement by lifting and lowering the handle. You can't manhandle it so don't even try.
After you have done a large area, take a mop and bucket and mop the floors a time or two. Then go to the next area and repeat the TSP/ buffer step and then the mop step.
After the entire floor has been scubbed with the buffer and the TSP, you will need to mop the entire house at least two more times. Wet the mop in clean water, mop and then squeegee out the dirty water into the other mop bucket. Remember that you are trying to remove any chemical residue and dirt from the floor. The cleaner the floor the better it will accept the acid and sealer later on. After the floor dries you are ready to apply the acid stain to your cement floors which is described in the next article.
