Selecting a mobile coatings unit requires knowledge and skill. Plus, when you invest in the proper equipment, you get to enjoy an effective and long-lasting rig that improves your overall business productivity.
In this post, you’ll discover how to choose the best mobile spray rig for you. We accurately describe the vital steps you should head consideration to before buying your spray rig.
4 Key Steps Involved in Choosing a Mobile Coatings Unit

1. What is the Purpose of your Spray Rig?
The first step to take before selecting the best spray foam rig is to define the purpose of the mobile coatings rig.
In general, these are the basic categories of use that determine the rigs that will work for you:
- Roofing/insulation
- Part-time/full time
- Residential/commercial
Are you interested in spraying foam insulation, spraying storage tanks, and other application methods?
While it’s true that some coatings rigs come pre-equipped, you can customize your spray rigs to fit your plan.
If you’re a residential contractor or home builder that deals with applications that require average output of 5-8 pounds per minute, a machine with a lower maximum output of 15-20 PPM is great – such as air-driven devices.
If you operate on both large residential and commercial projects and spend most of your time in these projects, hydraulic machines with more powerful output ratings are ideal.
Do you intend to install spray coating roofings? With the introduction of robotics in the spray coating markets, accuracy and maximum production can be achieved with high-performance foam and coating machines.
2. Do you intend on spraying both Foam and Polyurea Coatings?
Another determinant to consider is the particular material you'll be spraying. Do you plan to spray only spray foam, or do you have ideas for coatings, slab jacking, or pour coatings?
For instance, an air-driven closed-cell spray coating rig is common and easy to use if you're working on your home. These works ideally for small home renovation projects.
However, if you intend to spray several hundred or thousands of square feet, a more powerful hydraulic machine will work well for both coatings and spray foam. Whether you are a contractor needing to install open-cell foam or closed-cell foam, they are both rated as a moisture barrier and serve as a higher R-value than fiberglass or rock wool. Those with lower R-value can retain moisture and lead to mold.
3. Do You Require High Pressure or Low Pressure Spray Foam Equipment?

The third most important stage in buying or choosing a mobile coatings unit is defining the kind of pressure your rig should have. This can change the requirements of space and equipment needed.
If you intend to spray coatings only in a residential setting, you should select lower output spray equipment. However, for spray coatings or spray foam in a non-residential setting where much more material is required, you need a higher output hydraulic machine with more hose length, pressure ratings, and appropriate transfer pumps.
4. What Type of Trailer Do You Need?

Finally, it would help if you didn’t neglect your trailer type when planning to buy a spray coatings rig. It’s essential that the rig you purchase can conveniently pull the loads in your trailer while supporting the demands of the intended use.
For example, will the rig be employed in the city where congestion is likely, and space is a premium, or will you need access in a more challenging geographical location where maximum payloads and extra rugged suspension are required?
If you do a job where you carry mostly large loads, your rig should be customized to work for a goose-neck trailer, fifth wheel, or box truck. Note that if you want to buy used equipment, get the guarantee that it’s as efficient as the new one. Smaller loads can benefit from a box truck or smaller trailer.
Final Thoughts
In brief, this article serves as a short guide for choosing a spray coating rig for your small or large residential or commercial projects.
We’re hopeful that the four steps you read above will help you to make an informed decision. No doubt, the right investment in spray rigs will produce ripples of business benefits.
