Prepare the Roof for EPDM Rubber Coatings

One of the nice things about EPDM rubber coatings is the fact that you don’t have to be an expert roofer to apply them. As long as you have some time, the right tools, and the willingness to do it correctly, it is possible to do it on your own in most cases. Of course, if there is a massive roof, you will likely want to hire someone to take care of it for you. However, if the roof is less than 5,000 square feet or so, there’s no reason that one or two people can’t do it on their own.

Plan Your Application Days

While you can technically apply the EPDM rubber coatings in cold temperatures, or in very warm temperatures, you have to keep in mind that they require an ambient temperature of 55 degrees Fahrenheit or greater to cure. Ideally, you will choose a day when it’s sunny and between 70 and 75 degrees Fahrenheit. This ensures that it will be comfortable enough to work, the product can cure, and you won’t have to worry about rain. Before you can get to work though, you need to prepare the roof for the EPDM rubber coatings.

Preparing the Roof

You need to inspect your roof to look for signs of damage. Look for things such as corrosion, gaps, cracks, and tears. If there is rust on the surface of the roof, you can sand it away before you get started. Make repairs to any holes or tears before you apply the EPDM rubber coatings. You also need to clean the roof to remove any grit or grime that might be up there. Clean dirty areas with soap, water, and a stiff-bristled brush. Make sure that you let the roof dry completely before you start to apply the coating of Liquid Rubber. Different types of roofs will require different types of cleaning, naturally.

For example, if you have a concrete roof, there is a chance that it could be too porous for the EPDM rubber coatings to adhere to properly. This doesn’t mean you should give up the idea of these coatings though. First, test out a small patch. Apply the rubber coating and let it cure for about a week. Examine it and look for any indications that it isn’t adhering properly, such as bubbling. If that’s the case, you will want to apply a coat of epoxy onto the concrete first. This will fill in the pores. Let that dry, and then you can use the EPDM rubber coating to cover the roof.

The Application

Once you have prepared the roof, you will find that the application is actually quite simple. You add the catalyst, mix the product according to the instructions, and then use a roller to apply it to the roof. It goes on just like paint, and you will find that it can dry in about the same time. It’s a good and easy solution for those who need to protect their roof.
