Question

I am interested in using a wax or grease pencil to mark layers of finish on VCT. It is my understanding that Wal-Mart uses this procedure to alert their floor care technicians that a floor is in need of a scrub and top coating. The pencil marking is visible to the trained eye only. Iím not sure what color and would like to know more about the process and if anyone uses this.


Answer

We recommend putting down your base coat(s) and marking the top base coat with a red marking pencil. Then put down another coat and mark it with a yellow marking pencil. Put down another coat and mark it with a green marking pencil. Put down as many additional coats as necessary.
Train your employees to look for the 3 dots as they scrub the floor. If they see the green dot they scrub and go. If they donít see the green dot but see a yellow dot they caution you that finish needs to be applied. If they just see the red dot they stop and alert you that finish needs to be applied immediately. By marking the traffic area in several areas you can tell if you only need to apply finish to key areas or over the entire area.
JenMar Systems developed and previously distributed the Stoplight kit, a marking scale to better manage floor care needs. Stripouts can be reduced by monitoring traffic-wear into the base coat. Here are their original instructions:
JenMar no longer markets the pencils. The colors 02086 171T peel off china marker green, 02083 170T peel off china marker yellow and 02059 Red Rouge peel off china marker are available from Gray Enterprise www.grayenterprise.com.
Another option is to use a lead pencil which is readily available, but harder to view. You can number each coat of finish as it is applied. If you are relying upon workers to track the remaining coats, then the green, yellow and red dot stoplight system is a better choice. If a floor care manager tracks the coats and does not have the colored wax pencils then a minute lead pencil numbering system can work. Just make a note of which tiles contain the ID. Some managers track the wear visually (without marks) in order to prevent loss of finish that requires a deep strip. Of course your goal is to top coat as needed and as many times as possible.
