Q: I need to use a water-based roof coating on my roof due to coding regulations. I also have a significant amount of rust on my roof already. What should I do to remove the rust?
A: Topps has an excellent product to help prepare your rusted roof for a water-based coating. RAP™ actually converts rust into a more stable oxide and binds it into a primer layer for your water-based roof coating material.
Q: What do I need to do before applying RAP™?\
A: It is recommended that you scrub any loose rust off of your roof surface with a metal brush and then thoroughly power wash the surface before applying RAP™.
Q: How is RAP™ applied?
A: Apply RAP™ immediately after drying by pump-up sprayer, long handled roofing brush or roller, working it in for maximum absorption. RAP™ contains special penetrating agents to permeate and saturate rust. Working it in helps get best results.
