Abstract:
A method for protecting finished bathtub and shower pan fixture surfaces comprising the steps of:inspecting the application surface; applying masking materials to protect the application surface boundary; heating a protective material to a temperature of 120 degrees Fahrenheit, wherein the protective material comprises between 49% to 52% by weight of a pre-polymer mixture and between 49% to 52% by weight of a curative mixture, and wherein the pre-polymer mixture comprises 70% polymeric diphenylmethane diisocyanate, 25% 4,4-diphenylmethane diisocyanate, and 5% trischloropropyl phosphate; using a portable compressor sprayer further comprising a disposable spray nozzle tip wherein the pre-polymer mixture and the curative mixture are mixed at the disposable spray nozzle tip to apply the heated protective material to coat the application surface once an ambient temperature range between 45 degrees Fahrenheit and 85 degrees Fahrenheit is met; inspecting the protective material coating for consistency; adjusting the protective material coating by reapplying the protective material as necessary; allowing a period of ten (10) to fifteen (15) minutes for the protective material coating to cure; and removing any masking materials used to protect the application surface boundary.
