Tips for Applying EPDM Liquid Rubber Manually

One of the best ways to protect a roof from all manner of problems including UV light and leaks is with EPDM Liquid Rubber. One of the nice things about this product is that you will be able to install it on your own if you have the time and the DIY spirit. The following are some tips to help make it a bit easier for you.

Have the Right Tools

First, you need to make sure you have the right tools and equipment on hand. You should have an electric drill, a paddle mixer so you can mix up the liquid and the catalyst, and a roller, such as the type that you would use for painting. Just make sure that it has a rubber squeegee. You should also have a paint brush, and some rags and xylene for cleaning up if you make a mess. You will have up to four hours to remove any splashes or drips that occur using the xylene and the rags. Even when you are careful, chances are good that you will make at least a little bit of a mess.

One Coat Is All You Need

You only need to apply a single coat of the EPDM Liquid Rubber to get the desired results. You need to make sure that you apply the coat evenly, and according to the instructions on the container. Keep in mind that different types of roofing surfaces will allow you to spread the liquid at different rates. For smooth surfaces, you will need about one gallon for every 40 square feet. If the surface is rougher, you will need to change your estimate, as you will get about 30 square feet for every gallon. Use this as a basic calculation of how much of the EPDM Liquid Rubber you will need.

Don’t Paint Yourself into a Corner

This is a common saying because it happens, sometimes literally. Always make sure that you have a way to get off the roof as you are painting. You want to paint yourself into a corner of the roof and have to wait until it dries to get down!

Consider Working with a Specialist

Even though it is quite possible to apply your EPDM Liquid Rubber to the roof on your own, as you can see from the simple instructions, you might want to consider working with a professional. If you don’t have the time to do a proper job, or if you don’t have the tools, or knowledge, then a professional can help to ease your mind. You don’t want to get halfway through the application only to realize that you have air bubbles and that the EPDM Liquid Rubber isn’t adhering properly. If you feel that you need some professional help for the roof, there’s no shame in that. Just make sure that you hire a roofer who has experience with the Liquid Rubber.

Regardless of whether you apply the EPDM Liquid Rubber on your own or have some help, it’s important to take action soon. You want to make sure that your roof is protected.

    1. Hi here are the instructions for wood applications
      thank you

      When working with any wood application you first want to seal it with the ProFlex Primer. Porous and unstable substrates will not accept the application and will result in an ineffective cure. When working with applications over existing painted wood, clean the surface with soap and water to rid it of residual oils, debris and dirt. Scrape off any flaking areas. If you have washed the roof, ensure that enough days have passed so that any water absorbed into the wood has evaporated. When working with large commercial roofing applications, inspect the joints and seams. If there are any gaps 1/16 inch or larger, you will need reinforcement or filling. Wood application are not covered by warranty as it is impossible to verify the condition of the wood i.e. rotten wood or wood that has absorbed water.
