Using a liquid rubber roof coating is a fantastic way to quickly restore your roof to its best condition. You’ll achieve a roof that looks better and can stand up the harsh weather and temperatures without cracking or flaking. It’s versatile and will stick to a whole host of surfaces, making it one of the most popular roofing materials today.
Liquid rubber roofing is also one of the simplest materials to apply to your building. When you open a tin of rubber roofing, you’ll notice that it looks a lot like paint, and not surprisingly it does on in much the same way. You can apply it with a brush or a roller, but if you have a large surface area that needs covering, we recommend using a sprayer for a quick and easier job. Here’s how to get started with a sprayer.
First Prep the Surface
Before you start spraying liquid rubber roofing all over the place, you’ll first need to prepare the surface. If you try spraying it onto a dirty roof, the material won’t adhere as well and could bubble or peel before it’s had a chance to work. If your roof currently has an oily coating, you’ll also need to remove that, otherwise, the liquid rubber won’t adhere. Another important step before you start spraying is to check if you need to prime the surface. Some EPDM coatings require a base primer before you spray the rubber coating.
Tear Up Any Caulking
Before the days of liquid rubber roofing, caulk was commonly used to seal up vents, flashings, and other openings on a roof. The good news is that you no longer need that caulking and should remove it before applying your liquid rubber roofing. The rubber roofing will seal up those opening and last longer than outdated caulking.
Don’t Overdo It
Now that you’re ready to start spraying liquid rubber roofing, you must know just how powerful this stuff is. A sprayer is designed to make the job easier because it can spread the material far across the roof quickly. Adjust for any gusts of wind and warn anyone else on the roof before you start spraying. If the roofing material gets on clothing, vehicles, or your skin, it won’t come off easily. You’ll have to use mineral spirits to scrub the roofing material away. Therefore, it’s best to dress appropriately and be careful as you spray.
Don’t Clog the Sprayer
Another useful tip is to thin the liquid rubber roofing before loading it into the sprayer. When it comes out of the tin, liquid rubber roofing is quite thick and won’t easily spray out of your sprayer. If you’re struggling to make it work, try adding a little dash of solvent to the mixture to thin it out. We recommend using a five-to-one ration when you mix the two and to use a solvent specifically made for liquid rubber roofing. Contact the specialist from whom you bought your roofing, and they should have the solvent you need.
Using a sprayer to apply liquid rubber roofing keeps you from bending over with a paintbrush or roller. If you’re planning to cover a large roof with the coating, we cannot recommend enough that you use a sprayer. You’ll appreciate the ease, and you’ll be done much faster than if you were to follow a more manually intensive method. Just remember to prepare the surface beforehand and go light on the first coat.
