Okay, now that the commercial construction portion of the shop is done, it's time for me to ask for help from the forum.
I was power washing the floor today to get rid of all of the construction marks, including tire marks from the equipment used to erect the building and various mud, etc marks on the floor. After 8 hours, I only finished power washing about 1/4 of the floor inside the building (2000 sq ft). The tire marks from the construction equipments (lifts, front loaders, etc) are really embedded into the surface of the concrete. I can power wash them out, but it means setting the washer on narrow (approx. 1/4" wide spray) and takes forever. I can get the mud, etc up with a wide spray. Also with the narrow spray, it is blowing some of the top surface off of the concrete floor, revealing the aggregate. My thought is to only deal with the dirt/mud with the power washer and hope the acid etch (to come in the future before I epoxy the floor) will take care of the tire marks. Any comments/suggestions/thoughts?
The second problem is that now I am putting water on the floor, it all accumulates in the area where I am planning on putting my office. The floor apparently flows back to the rear of the building (instead of toward the shop doors). Unfortunately, it leaves as much as 1" of water in the area where the office is to be built. I am one of those people that washes my shop floor at least once a week. With that potential for water flow/standing water, what is the best way for me to keep water out of the office area and what should I use when I put the office walls in place to keep (1) water from coming under the walls and (2) keep the walls from rotting from the water. Although I squeege the water up when I clean, it is a lot of water right at the area where the shop office is goigin to be located.
