Joint Fill & Repair

Heartland Warehouse Renovation

Introduction:

This article explores the real-world training and application of the SealBoss® 6500 QuickFix Polyurea Joint Filler and the JointMaster® Pro2 Pump during a recent aerospace facility renovation project. The focus is on the critical importance of proper industrial floor joint repair in high-performance environments, particularly in sectors with heavy equipment use and stringent facility requirements.

The case study is based in St. Louis, Missouri, where a local contractor—new to joint filling work—was selected to complete repairs on 6,000 linear feet of floor joints. Understanding the complexity and performance standards expected by the aerospace client, the contractor partnered with SealBoss for professional training. A SealBoss Technical Representative provided on-site, hands-on instruction to ensure proper use of both the material and the pump system.

This project showcases the effectiveness of direct technical support and the role of quality equipment in enabling successful outcomes, even for contractors without prior experience in joint filling. It also highlights how tailored renovation work helps prepare industrial floors for the heavy-duty usage expected in aerospace and manufacturing environments.

As the construction of tilt-up concrete buildings and warehouse facilities continues to rise nationwide, many existing structures are not immediately suitable for new tenants and require modification before operations can begin. Floor joint restoration using reliable products like SealBoss 6500 Polyurea and the JointMaster Pro2 Pump can be an essential part of that process—ensuring durability, performance, and long-term facility integrity.

SealBoss Expertise Elevates Industrial Floor Joint Repair at Aerospace Facility

On-Site Training Brings Professional Results in St. Louis, Missouri

In the thriving industrial hub of St. Louis, Missouri, SealBoss was called upon to provide specialized, on-site training in the use of  SealBoss professional-grade Floor Repair Systems.

A SealBoss Technical Representative visited a local contracting team to deliver targeted instruction in joint filling techniques using the SealBoss® 6500 QuickFix Polyurea Joint Filler and the JointMaster® Pro2 Dispensing Pump.

This hands-on training session was designed not only to introduce the contractor to SealBoss technologies but also to prepare them for an urgent renovation at a warehouse soon to be occupied by a major aerospace company. The goal: enable a successful, high-performance floor joint fill that would meet the strict operational standards of a high-profile tenant.

Meeting Aerospace Industry Demands with Advanced Joint Filler Technology

The aerospace industry places exceptional demands on facility infrastructure. In this case, the client required a durable floor surface capable of handling continuous heavy forklift traffic and the movement of substantial aerospace components.

To meet these challenges, the project team selected SealBoss 6500 QuickFix Polyurea, a fast-cure, heavy-duty joint filler with A 80 Shore hardness and 200% elongation. This advanced material is engineered for industrial environments where impact, stress, and movement are constant. Its flexibility and toughness ensure long-lasting performance—especially crucial in environments that cannot afford downtime.

Equipping the Team: The JointMaster® Pro2 Joint Fill Pump

The project marked the first time the contractor used the JointMaster® Pro2 Pump, a battery-powered, dual-component pump designed specifically for dispensing fast-setting polyurea joint fillers. Recognizing the importance of proper equipment use, the SealBoss Technical Representative provided detailed instruction on pump operation, material mixing, flow control, and cleaning procedures.

Thanks to its intuitive design, the pump quickly became a natural extension of the crew’s workflow, allowing for precise, efficient filling throughout the day.

Scope of Work: 6,000 Linear Feet in One Day

The scope of the project was significant: fill and finish 6,000 linear feet of floor joints within a single day. While ambitious, this target was achievable through careful planning, expert training, and the efficiency of the SealBoss system.

Day-Before Surface Preparation

Preparation began the day before joint filling, with the contractor removing all failed or deteriorating joint material. Adhesion and delamination issues were resolved, and the joints were cleaned thoroughly. Backer rod was inserted to the proper depth across all areas to ensure optimal material flow and control during the next day’s application.

Streamlined Team Configuration for Maximum Efficiency

To complete the project in the shortest possible time while ensuring seamless execution and maximum efficiency, a three-man crew configuration was implemented:

  • Pump Operator – Managed flow and refill, maintaining steady output from the JointMaster Pro2 Pump.

  • Joint Filler Applicator – Guided the dispensing nozzle and ensured joints were filled evenly.

  • Floater / Finisher – Performed critical joint shaving within 8–15 minutes of fill, maintained supply of materials, and ensured the entire process stayed on track.

This streamlined crew layout proved highly efficient for fast-paced, high-volume joint filling. 

From Training to Performance: Results That Speak for Themselves

After a concise yet thorough training that included a product overview, equipment setup, and a 20-minute hands-on session, the contractor’s team quickly demonstrated their ability to handle the task. With a dispensing rate exceeding half a gallon per minute, the crew successfully filled and shaved the entire 6,000 feet of joints in a single day.

This successful outcome underscores the transformative value of SealBoss support—empowering even less-experienced contractors to deliver professional results under demanding conditions.

Conclusion: High-Caliber Products Paired with Expert Support

This project in St. Louis exemplifies the SealBoss commitment to excellence—combining premium products with in-person technical training to deliver top-tier industrial solutions. As the demand for tilt-up warehouse renovations grows across the United States, projects like this one illustrate the value of selecting a partner who goes beyond product sales and invests in contractor success.

With SealBoss 6500 QuickFix Polyurea Joint Filler and the JointMaster Pro2 Pump, facilities can be prepared to meet the rigorous demands of aerospace, logistics, and other heavy-duty industries—quickly, efficiently, and professionally.

Freezer Floor Crack Repair

Freezer Floor Crack Repair

Freezer Floor Repair

The addage ‘time is money and money is time’ is no mystery to warehouse operators and owners.

When valuable foods such as meats, seafoods or produce are stored in areas with cold temperatures, floor repairs needs can start to present themselves, especially when ice becomes an issue.

In the freezer department of a food handling facility, the transition threshold between the freezer area and the cold prep area was in jeopardy due to spalling.

Warehouse operators and owners understand how important it is to keep the floors in smooth and navigable condition.

Besides the obvious concerns of safety, hygiene, and aesthetics, pallet jacks may get stuck and damaged, and warehouse forklift wheels take a constant pounding.

Safety is the always the number one concern for the responsible and liable business operators.  Pallet jacks and forklifts need to run as smoothly as possible over floors, ramps, and transitions — for the security and safety of the operators and the merchandise.

Forklift tires and other impact related repairs or equipment replacement can be very expensive. When the equipment is rattled and chewed up by damaged concrete floors and ramps the costs add up quickly.

Last, but not least, good hygiene and manageable, clean surfaces are an expected standard in a food product environment.

Something Needed To Be Done

Freezer Floor Crack and Spall Repair with SealBoss QuickFix

SealBoss 6060 QuickFix has the ability to cure in temperatures as low as -20° F / -29° C making it an incredibly resilient and reliable product to repair damaged floors in the harshest conditions.

With a set time of less than 5 minutes at room temperature, a good repair team can return a warehouse floor back to service in the same day, keeping business flowing and the revenue stream healthy.

Warehouse owners do not have the luxury of waiting full shifts to allow for products to cure over the span of several hours but rather need something that can get the job done within half of a working day.

Prior to the repair, SealBoss 6060 QuickFix has to be thoroughly mixed and, when used in colder ambient temperatures,  conditioned to room temperature in order to achieve the best results. Properly prepped material is key to ensuring the job goes smoothly, as the final curing of the material happens only within minutes after applying the mixed material.

The spall has to be dry, debris free and uniform in depth, with a minimum of ¾ of an inch. Taking these steps will ensure good adhesion and prevent delamination.

As an example, with this job where the material was used to great success, a blowtorch was applied briefly to the substrate in order to melt and remove any ice, to get rid of excessive moisture and to warm up the general area for good bond and quick cure.

Important: Application should not leave any gaps between substrate and repair. Any entry points for water must be sealed to prevent water from entering. Joints and gaps can be filled with flexible SealBoss 6500 Polyurea Joint Filler.

When used in conjunction with the SealBoss 6500 Polyurea Joint Filler, these two SealBoss QuickFix Line floor repair products provide a 1-2 punch that allows for fast back to service operations.
