If you want to remove the roofing paint, you might want to dry and thoroughly sweep your roof surface in order to not have dirt and dust within your primer when you begin sealing. Use a paint scraper for this process.
Tip: Any debris left on the surface can hinder the bond you want to achieve when sealing.
Step 2: Prime. You can use any primer so use a rolling brush that covers the entire area with ease. It is necessary to have a roller brush for this. It is best to dip it in primer. Don’t put generous amounts of primer on the brush as it can drip and make your project look awful. When everything is completely covered the brush, allow it to dry.
A tip: You don’t have to be meticulous to prime your roof.
Seal the roof. Secure the roof when the primer has dried. The steps are the same as the second step. It is important to protect all the roof’s surfaces when sealing to avoid moisture from entering the roof.
