The process of cleaning an entire plant at the end of each day is a labour intensive task.  If you add up all of the hours required each year to clean, you end up spending one quarter of a full time position.  We have explored several ways to speed up the cleaning process, and one of them is to paint the entire shop floor.  The paint has many benefits: it is smoother than bare concrete so the effort required to move a broom and dirt across the floor is less; the dust generated is significantly decreased; machining oil and coolant cannot stain the floor; and finally, as a bonus, the work area gets much brighter.  Below, we show several pictures illustrating the process.  While we do not generally like to share pictures of a "dirty" shop floor, it is important to show the contrast.

 At the start of the process we had to do a thorough cleaning of every corner of the shop.  This was a great opportunity to do a kaizen event in each work center.

 This is an embarrassing picture of the mess under our machining center.  After a few years of coolant and oil making it's way to the floor the concrete has becoming so stained it was impossible to clean anymore.

 Here is the start of the floor painting process.  The huge difference between the bare concrete and the painted section is noticeable both in appearance and overall brightness from the reflection off the white surface.
