Spray foam application has many intricacies that beginner contractors might struggle with. Because of this, we often see beginner contractors making the same mistakes as they start their own spray foam businesses. Fortunately, there are tips and tricks you can use to prepare and avoid these mistakes in your own business. Learn some of the common mistakes people make when starting a spray foam business and how to avoid these same mistakes in your own work.
Selecting the Wrong Equipment
There are many types of spray foam systems to choose from on the market. The three main types of spray foam systems include air-driven machines, electric machines, and hydraulic machines. Each machine has a different output rate, lifespan, and cost-effectiveness, which are all factors to consider before choosing your spray foam system. A beginner mistake is to rush into purchasing your first system, only to realize that you can’t keep up with the maintenance costs or it doesn’t offer enough output.
Beginner contractors may also forget about basic maintenance for their equipment. Don’t put off cleaning out your spray foam system after a job—the compacted foam can harden in your spray foam hose or gun and cause endless headaches later. Instead, be sure to flush out your spray foam hoses, guns, and other equipment between uses.
Choosing the Wrong Spray Foam
Not only are there multiple pieces of spray foam systems and equipment but there are also multiple types of spray foam. Each type of foam has unique qualities, which is why it’s best to understand each type and their applications so you can select the right spray foam for the right job. There are three main types of spray foam: high-density foam (closed-cell foam), medium-density foam (closed-cell foam), and low-density foam (open-cell foam). High-density foam is ideal for insulating large-scale, commercial buildings and other applications. On the other hand, low-density foam is best for tackling small-scale projects due to its smaller coverage and expanding properties.
There is also the difference between closed- and open-cell foams. Closed-cell foams have higher density, R-value, and water resistance, while open-cell foams offer more expansion and flexibility. These slight differences add up and can influence the quality and efficiency of your spray foam project. Be sure to compare your application needs with each type of foam you choose.
Not Following Correct Spray Techniques
There is a precise method for applying spray foam insulation, which is why it’s not always recommended that homeowners take on spray foam DIY projects. Those who lack experience may try to apply the insulation all in one go rather than using the correct layering technique. When applying spray foam, the contractor will make one pass along the wall, roof, or other surface, allow this layer to expand and cool, then pass over it again with more layers. Inexperienced, do-it-yourselfers or newcomer contractors may try to apply the spray foam all in one layer. Alternatively, some beginners may know how to work in layers but fail to give the foam proper time to expand and cool before adding an additional layer. Spray foam application takes time and patience to apply correctly.
Incorrectly Mixing Spray Foam
Spray foam is a unique form of insulation because you must prepare it at the site of the application. The main chemicals involved in forming spray foam are isocyanate and polyol resin, which must be mixed fresh on-site and applied right away to stick to the desired surface. Therefore, you must have all the materials and equipment present on-site to start the application process. Pay close attention to the ratio of ingredients and the temperature of your surroundings and the spray foam mixture itself. You’ll know when your spray foam mixture isn’t successful when it contains a waxy or flaky debris and has a lingering odor.
Improper Storage Conditions
Spray foam chemicals have specific temperature requirements during storage. If you fail to store these chemicals at the required temperatures, they could become damaged and you could waste entire quantities of spray foam materials. The ideal temperature at which to store spray foam chemicals is between 70 to 80 degrees Fahrenheit, but it’s always best to compare with the manufacturer guidelines to ensure accuracy. Storage at any temperature lower than 70 degrees could cause your spray foam to become thicker and harder to apply.
Rushing the Spray Foam Application Process
Efficiency should never override quality when it comes to your spray foam application process. While trying to establish your spray foam business, you want to take your time and perform high-quality spray jobs to secure positive customer reviews. Efficiency and speed will come with experience. You don’t want to risk uneven coverage or even missed spots by rushing through your jobs. Gaps in spray foam coverage can lead to spikes in energy bills and even mold problems for your clients. Your customers will understand that quality takes time, and many will prefer a lengthier, high-quality job compared to a speedy, incomplete one.
Failure To Account for Overspray
Overspray occurs when the residual foam from your spray gun lands on surfaces outside of the ones you’re actively coating with insulation. Because spray foam cures into a hard material, it can be difficult to remove without the right equipment. Overspray can make your application look unprofessional and unfinished. Fortunately, there are ways contractors can prevent overspray in the first place. Remove additional furniture, appliances, light fixtures, and other objects from the spray site. For objects and surfaces that you can’t transport, be sure to cover these items with tarps and suitable coverings. Additionally, when working outdoors, make sure to use a windscreen and barricade the spray foam site.
