How to Waterproof With PTEF

For canvas roofs or coverings that are constantly exposed to the elements, a waterproofing treatment can not only add life to the canvas but keep those sitting underneath drier. By waterproofing a canvas roof on a boat, RV or awning you can prevent mildew, mold and rot. PTEF waterproofing spray can be sprayed on a clean canvas roof or awning by the homeowner and will provide visible waterproofing protection after it has been allowed to dry for the recommended time of six hours.

Instructions

    • 1

      Clean off the fabric roof before applying the PTEF waterproof spray. If the canvas is especially dirty, use a sponge with soap. Otherwise, just spray it off.

    • 2

      Let the canvas dry naturally until it is completely dry.

    • 3

      Spray the PTEF waterproofing solution on the canvas. Spray until you can see the canvas is saturated and looks darker than the parts that have not yet been sprayed.

    • 4

      Let the PTEF dry on the canvas for the next six hours.
