Manual Application Instructions for EPDM Liquid Roof®
Liquid Roof is ONLY for Recreational Vehicles, Mobilehomes and Trailers
Surface to be coated should be clean, dry and structurally sound. Fasten loose areas with adhesive (contact cement) or pop rivets. Oil or wax must be completely removed with solvent. Remove loose portions of existing coatings and brittle caulk with scraper and wire brush. Whatever still has good adhesion may remain to be recoated. Rusty or pitted metal should be wire brushed to remove loose oxide. Tightly adhering corrosion may be directly coated with Liquid Roof.
Asphalt based aluminum coatings should be removed as much as possible by wire brush or abrasive disc. Roofs previously coated with elastomerics or other coatings must be primed with the ProFlex Primer. Also if your roof is an Alpha roof you will need to prime prior to the application of the liquid roof. Roof cements should be removed and replaced with butyl caulk where necessary.
Coverage:Liquid Roof® will cover up to 46 square feet per gallon on a very smooth surface. Normal coverage is 40-42 square feet per gallon on an average substrate. The required 20 mil film thickness will be achieved when the above spreading rate is used.

You will notice when you get your product the can is somewhat under filled, this extra room will allow for you to mix the catalyst without having to pour the material out in another container. You can watch a mixing video here We suggest mixing the material first without putting in the catalyst for approximately 1 minute then pour in the catalyst and mix for an additional 4 minutes. Once the catalyst is added you have four hours to use the material before it begins its initial set up.
