GacoWash
Concentrated Cleaner

GacoWash is a concentrated cleaning solution for roof membranes and existing waterproof systems. It is specially formulated to remove tough dirt, pollen, mildew and fungus from roof membranes and existing waterproof systems. GacoWash should always be the first step in every GacoFlex Silicone Roof Coating System.

For general cleaning, combine 1 part GacoWash Concentrated Cleaner with 9 parts water. When mixed at a 9:1 ratio, 1 gallon will clean up to 4,000 sq. ft.; higher concentration may be needed for adequate cleaning.
