Trial Number 3

Trial Purpose:

To analyze how affective it dulls the contaminant from the surface of floor tiles.

Date Run:

07/08/2014

Experiment Procedure:

Nine floor tiles were coated twice with latex enamel satin black colored. The coating was left to dry for a day before testing the ease of removability of the latex enamel from the floor tile with the chosen cleaner products. Each cleaner was given three coupons for testing. The cleaners were applied onto the coupons with a standard spray bottle with three sprays on each individual coupon and let soaked for fifteen minutes. After fifteen minutes of soaking the coupons were pat dried manually with a paper towel.

Trial Results:

Cleaner L* L* L* Ave L*
TSP Liquid Substrate 25.59 25.99 1.56 1.25
TSP Liquid Substrate 25.45 25.79 1.34

TSP All Surface Paint Prep 25.57 27.40 7.16 30.4
TSP All Surface Paint Prep 25.56 28.58 11.82  
TSP All Surface Paint Prep 25.61 44.11 72.24  
Moldex Paint Prep 25.60 25.79 0.74 0.27
Moldex Paint Prep 25.61 25.55 -0.23  
Moldex Paint Prep 25.58 25.66 0.31  

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

TSP All Surface was the most effective remover of the paint, but it also led to paint chipping on the tiles. Moldex paint prep and TSP liquid substitute did not exhibit significant dullness after a manual towel pat down.
