Moisture intrusion can be the demise of many structures, including roofs, foundations, and cement walls. Waterproofing can be used to protect these materials after construction, ensuring that they stay sealed throughout their lifespan.

Most industrial projects utilize spray machines to apply liquid waterproofing materials. Choosing a machine that’s tailored to your project ensures optimum results, but it’s not always easy to identify what product you need.

In this blog, we will break down the main factors involved in choosing a waterproofing spray machine and why a mobile trailer may be the most practical option for contractors.

The Importance of Selecting the Right Spray Machine

A poorly sized or configured waterproofing coating machine can spell disaster for your next project. When choosing a sprayer, you’ll want to consider various factors, with one of the most important factor being the material you plan to use (polyurea, liquid membranes, elastomeric coatings, etc.).

There are multiple consequences that can come from selecting the wrong machine, including:

• Project Downtime: A machine that’s incompatible with your waterproofing material can clog or fail outright. This directly correlates to more downtime on the job and decreased revenue for your team.
• Material Waste: Each spray machine configured by Bolair Fluid Handling is designed with a specific material in mind. Out of sync material and spray machine will be incredibly inefficient,wasteful and costly.
• Inconsistent Spraying: From excessive overspray to winking, the wrong machine can suffer numerous malfunctions that make your waterproofing project a chore.

Why Trailer-Mounted (Mobile) Spray Rigs Are So Practical

Most spray contractors move from job site to job site. Traditional spray machines have to be lugged along with them. Mobile spray setups are a faster, easier-to-transport solution that makes frequent waterproofing projects simpler. In addition, housing your waterproofing spray equipment in a mobile rig/trailer/truck can ensure that all the necessary components of your job are always present and ready to perform.

There are a few key benefits that mobile units provide to professional waterproofing contractors, including custom configuration, time and cost efficiency, all-in-one operation, and safety.

Custom Mobile Spray Rigs

Custom configurations allow a waterproofer to design a mobile unit that directly suits their needs and budget. The size of the operation and its accessibility can also determine what type of mobile setup is required. A few of the most common configurations are described in the chart below.

Time-Saving and Cost-Effective Benefits

Another primary advantage of a mobile unit is that it saves Canada waterproofers time and money. Loading spray equipment into a vehicle, unloading it at the job site, and setting up the machine can slow down the project. Over many projects throughout the year, this eats into profit margins.

Mobile units can be easily transported to the job site and are ready to spray as soon as you arrive. In addition, towed units can be detached from the truck and left at the job site, freeing up the vehicle for other uses.

Comprehensive Units

Mobile spray rigs are customized to a contractor’s preferences. This means that individual components can be carefully chosen to meet a team’s needs. In addition, mobile units are all-inclusive and can be designed with all of the necessary equipment - heated hoses, spray machines , transfer pumps, and onboard power generators.

Designed for Safety

From a safety and logistics perspective, mobile units are much more desirable for a spray technician. They’re built with fire safety mechanisms, ensuring that the equipment doesn’t overheat and cause damage even when you’re away from it in the field. In addition, enclosed mobile rigs offer protection from the elements.

Factors to Consider for Your Mobile Spray Setup

With so many different options for mobile trailers, it can be difficult to decide which is best for your operation. Before deciding on a unit, you’ll want to consider the size and environment of your typical projects. As described above, some mobile units are better for large industrial projects, whereas others are better for tight, off-street spaces.

After choosing the mobile rig format (trailer, enclosed, box truck, or portable), you’ll want to think about which devices you want installed. Every mobile spray rig from Bolair can be customized with the proportioners, hoses, and power supplies you want, all from your preferred manufacturers.
