Grill Mask is not all the same quality. For duct tightness pressure testing, there are two grades, low tack and high tack. Retrotec grill mask is a high tack product. It costs more and less at the same time. While low tack is cheaper, it does come loose from time to time, particularly over extended testing periods. This results in labor losses tracking down leaks that don't exist. So while it costs a little more up front, high tack mask will save you money on the back end. Lost labor costs are definitely more than the difference! Try it, you will see the difference.
NOTE: Please take care when using this product on freshly painted or stained surfaces.
