When it comes to painting a rubber roof, not just any paint will do. Most will crack or bubble within a year due to the elements. If you're unsure of the proper type of paint for your project you can call different roofing or paint companies to get their opinions. You might need to call more than a few since they will want you to pay them to do the job. You will also have good luck with pain store employees since it's their business to know the uses of different kinds of paint. Getting the job done is an easy task, once you have the proper materials.
Step 1 - Choose Your Day of Painting
Not every day is ideal for painting. You'll want to avoid days with high humidity as well as cloudy days because of the chances of rain. Keep an eye on the weather forecast. Make sure it won't rain less than 24 hours after you are done painting.
Step 2 - Prepare the Area to be Painted
First and foremost, you should only paint clean, dry materials. Sweep and mop the entire roof and allow it to dry. Avoid cleaning the roof on windy days. Your efforts will often be in vain.
If the roof you will be cleaning is huge, it's a good idea a portion you know you'll be able to clean and paint it without being interrupted for a significant amount of time. You can alternate cycles of cleaning a portion, painting that portion, cleaning another portion, painting that portion, and so on. If you spend an entire day cleaning the rooftop and something comes up to prevent you from painting until the next day, you'll have to clean all over again since the area will no longer be clean enough to paint.
Step 3 - Prepare to Paint
Because regular acrylic paint easily cracks, you are going to need to purchase urethane elastomer coating. This turns your adhesive coating into a paint. Not only are you adding color to your roof, but you are also adding an extra layer of sealant protection.
Follow the manufacturer’s directions. Some types of paint require you to shake the can. Other paint types require you to stir the paint.
Step 4 - Paint the Roof
Using a paint roller, start at one end of the roof and paint up and down in even strokes. Apply thin, even coats. Painting your roof is similar to painting the walls of a room. Make your way around the roof ensuring that you apply the paint to the entire area. Be careful not to paint yourself into a corner. You don't want footprints all over your fresh paint.
Climb down onto the ladder to apply the paint to the area that you couldn’t get to while you were standing on the roof. Use the small roller brush for this last area. Allow the paint to dry at least 24 hours before applying a second coat if it's needed.
