Trial Number 6

Trial Purpose:

To evaluate bio-based floor strippers.

Date Run:

01/13/2005

Experiment Procedure:

Three products were used at 100% v/v concentration. Nine pre-weighed plastic composite tiles were coated with Johnson Wax Professional Show Place floor finish (40861-29-8, 78-51-3, 34590-94-8, 111-90-0) using a hand held swab. The finish was dried using a hand held heat gun for two minutes at ~300 F. Once the finish/coupon had cooled, three more coats were applied following the same procedure. Coupons were reweighed to determine the amount of finish that was applied.

The coupons were sprayed with a cleaning product. The formulation was allowed to sit on the finish surface for 10 minutes. Three coated coupons were firmly held against a rotating abrasive pad (175 rpm) which was purposely designed to imitate the working properties of the floor stripping machine. The cleaning lasted for 1 minutes (175/2 revolutions). At the end of the cleaning, the coupons were wiped once to remove any cleaner and left to dry for about 1 hour. Final weights were recorded and efficiencies were calculated.

Trial Results:

The three products removed only a small amount of the floor finish. The table below lists the amount of finish applied, remaining and the percent effectiveness for each coupon cleaned. Some of the plastic coupons resulted in cleaning efficiencies over 100%. These coupons had noticeable damage caused by the scouring action.

Success Rating:

A follow up test, usually based on company input.

Conclusion:

These results are not conclusive, especially for the Bio-T-Max or SC-Actisolv because it seems that the abrasive pads assisted in the removal of most of the contaminants when these products were used on the substrate.  However, the abrasive action may have removed the contaminants and also parts of the substrate.  These experiments will be repeated using ceramic tiles.
