Ideal Accessories for Your Polyurea Pump

Concrete is a diverse medium for use in residential and commercial spaces.  Concrete workers and interior designers are able to maximize the flexibility of concrete via its texture, color, and sheen, at a rate that is easy on the budget.  As miraculous as concrete seems, it also needs to be properly installed and maintained to avoid excessive cracks.  However, not all cracks in concrete are bad.  As a matter of fact, the installation of concrete requires certain planned cracks, called control joints, to ensure that the cracking is manageable and works with the functionality of the flooring.  The control joints work to manage the contraction and expansion of the concrete as it cures and dries.  Cracks are inevitable, but by creating control joints and utilizing the proper fillers, any damage from the natural contraction and expansion of the concrete is mitigated.  Ensuring the control joints are spaced out properly is the key to the reduction of unwanted cracks.

When the control joints are created, they need to be filled in order to provide the necessary cushion between the two pieces of concrete.    There exist two industry standard types of joint fillers:  epoxy control joint fillers and polyurea control joint fillers.  Polyurea joint fillers are the easiest to work with of these two fillers.  Fast setting with a flowable pour, the polyurea joint filler is a great choice for people who want to not only filly joints, but also for caulking and crack repairs.  Polyurea filler is also versatile in that it can be made in a variety of colors.

What is the Purpose of a Polyurea Pump?

While the polyurea control joint filler is versatile, it does require the combination of two chemicals at the time of placement in the control joint. Because of the fast setting aspect of the polyurea joint filler, you need a pump that allows you to merge and apply the compounds at a rapid pace.  Once the two compounds merge, they start to cure and dry.  Polyurea pumps apply the fast-acting, merged compounds to their proper place in the control joint quickly.  Typically a job for multiple people due to the dual components, the polyurea pump makes this a one-man job, reducing labor costs and allowing the joint filler to be applied swiftly and with maximum precision.

Top Accessories for Your Pump

Every great tool needs equally as great accessories.  The polyurea pump is no different.  Because the polyurea joint filler is applied to cracks, both planned and unplanned, it is important to ensure the cracks are clean and free of debris.  Many times, joints that have been filled will need a new application of joint filler.  In order to do this, it is important to remove any remaining filler to ensure proper cohesion.  This is where the crack chaser plays a vital role.  The U.S.SAWS 5” hand-held premium crack chaser is a prime example of a high-quality crack chaser.  This handy tool is small and lightweight making it perfect for use horizontal and vertical repairs.  It also comes equipped with dry diamond blades.

A power inverter is another great accessory for the polyurea pump.  In using a battery, the polyurea pump is freed from the constraints of the power cord.  Cord-free operation is handy for those tight situations where a cord can get in the away, or in times when a power source is not conveniently located nearby.  U.S.SAWS 1200W Power Inverter is a great choice.

Because of the quick setting materials in the polyurea filler, it is vital to clean the components to the pump quickly after use.  Having a replacement pump on hand is always a good call.  The U.S.SAWS Polyurea Replacement Pump works to prevent seal leaks and is much easier to clean.

Finally, as the tanks are a vital piece of the polyurea pump puzzle, it is always a good idea to have replacement tanks for the pump as well.  A spare resin tank and a spare hardener tank on hand will ensure that should there be any issue with your current tanks, you have clean, debris-free spares to use.

The Brilliant Belly Saw

Often time contractors find themselves stuck in tight situations where large diameter pipe needs to be cut, but the conditions are not optimal for the use of industry standard pipe cutters or saws.  Cutting pipe in cramped conditions can be a real nightmare.  Couple that with wet conditions and you could be setting yourself up for disaster.  That’s where the U.S.SAWS Belly Saw comes in and makes life a whole lot easier for those wet cuts in narrow spaces.

Applications of a Belly Saw

The belly saws supplied by U.S.SAWS are ideal for pipes ranging from 8 inches to 24 inches, 24 inches to 48 inches, and 48 inches to 72 inches in diameter.  Contractors and utility workers use these innovative saws for cutting subgrade pipes in tight conditions as it only requires 7 inches of clearance to work, eliminating the need to clear out excessive amounts of dirt to create the cut, which then saves significant time and effort.  If a pipe has burst and needs to be cut and repaired, having to clear out a wide area of sludge under and around the pipe increases the amount material lost from leaking out of the pipe and requires more effort and manpower to clear out, thereby increasing the total cost of the job.  The belly saw provides the workers the ability to make the cut quicker by reducing the amount of space needed for saw clearance and under safer conditions.

U.S.SAWS manufactures and sells belly saws that are pneumatically or hydraulically powered.  These powerful saws with their Tiger Tooth blades make cutting PVC, HDPE, ductile iron and cast iron pipes a breeze, creating precision cuts every time.

Benefits of a Belly Saw:  Increased Safety

Wet and tight are never conditions that meld together to create a safe pipe cutting scenario.  U.S.SAWS has solved that problem through their belly saw. U.S.SAWS is always looking for ways to develop tools that protect workers.  Their belly saws do not disappoint in this regard.  These saws are water saws in that they are ideally used in wet conditions.  As safety is paramount in the design of these saws, U.S.SAWS first ensures that the saw is equipped with its top of the line Tiger Tooth saw blade.  Sharp blades make lessen cutting time, which then reduces the amount of time spent using the saw.  For cutting pipe ranging from 8 to 24 inches, the belly saw comes equipped with an 8 inch blade.  Pipes with diameters of 24 to 48 inches and 48 to 72 inches would use a belly saw equipped with a 12 inch Tiger Tooth blade.  The next safety feature of the belly saw is its clamshell design.  This shell design surrounds the saw and protects the workers from those sharp blades before, during and after the cut.  Another safety feature for these saws is how they are powered.  By using air or hydraulic power in small, cramped spaces, emissions are non-existent, and workers are not forced to breath in harmful fumes.  Finally, the vital safety feature of this water saw is the strap used to affix the saw to the pipe.  By strapping the saw to the pipe itself, the saw can be drawn around the pipe for a fast and accurate cut.  Further, U.S.SAWS supplies a “water kit” for use with steel pipes to suppress sparks.

Save Time with U.S.SAWS Belly Saws

Not only has U.S.SAWS taken safety into account for the development of their belly saws, they also want to ensure the saw is an efficient tool.  The entire purpose of the “tool” is to make a regular job easier.  U.S.SAWS understands that time is money, not only for the workers, but also for the municipalities or businesses employing the workers or supplying the materials flowing through the various pipes.  The 7 inch clearance space required to cut fully around a large diameter pipe is nothing compared to other tools used for similar jobs.  Less prep work means less time and money spent.  By requiring such minimal clearance for such a large job, the workers’ time normally spent on clearing space, can be used attaching the saw and focusing on creating an accurate cut.  Further, the accuracy provided by using the strap and wheel system requires less effort by the workers during back breaking work, and also enables the workers to make easy accurate cuts, reducing the need to fix a poor cut.

U.S.SAWS is an innovator in the tool industry.  In balancing safety and efficiency, U.S.SAWS has developed yet another saw that will revolutionize the world of pipe cutting.  Contact U.S.SAWS today to find the right belly saw for your business

The Importance of Concrete Surface Prepping

Since before the time of the ancient Romans, concrete has been a vital resource for use in the industrial and construction world.  Over the last several years, however, concrete use has spilled over into the interior design world as well.  Because of its price point, durability and variety, concrete floors are popping up all over commercial and residential locations.  Whether the building owner is looking for that “unfinished” industrial chic look or just sees the practicality of inexpensive flooring, concrete floors have become all the rage.

Concrete surfaces are known for their hardness (no dropped egg is going to survive a tumble in a kitchen with concrete flooring, although, a great rug will help in that regard).  They’re also known for their durability and versatility.  From utilitarian finishes to texted, chic colors and designs, concrete surfaces can bring style to the most humdrum of locations.  Of course, obtaining and maintaining that high sheen requires some work with concrete specific tools.

In order to get the finish you want, whether it is for a repair or a new floor, it is important to ensure the concrete is prepped properly prior to applying any finishing coats.

Remove Debris and Material

While concrete flooring is definitely a low-maintenance flooring option, there is some intense preparation that needs to be done to achieve and maintain that highly finished look.  Surface preparation is the key to ensuring your concrete flooring finish lasts.   The first step in proper surface preparation is to remove any debris or material that will affect the finished product.  Initially, this can be done with a broom and vacuum, but the process doesn’t stop there.  This work is done with concrete grinding tools and requires specific safety gear to protect the workers from hazardous fine dust particles that can get into their lungs.  The purpose of the grinding is to remove any damaged or weak concrete from the slab.  This also helps clean the surface of any oil or residues that may be on the concrete that would inhibit the finishing process.  After the concrete has been ground down, it is important to roughen up the concrete with the right abrasive technique.  Depending on the purpose of the flooring, there are several different techniques, such as acid etching, abrasive blasting, and water-jetting, that are used to roughen up the surface to ensure the sealants and overlays last.  Once the concrete has been roughened up, you can go ahead and add your sealant and overlays.

Cleaning and Repairing Concrete


With so many daily stresses in our lives, it’s great to know one thing can be simple, and that is cleaning up concrete flooring.  Tile flooring can get dirt and grime wedged in the grout in between the tiles.  Carpets can stain due to spills and dirt, some of these stains wind up being permanent.  Concrete flooring avoids all of these hassles.  It is easy to clean and maintain and just requires some maintenance every few years.  The properly finished concrete surface is resistant to water, stains, and abrasions.  This makes cleaning up dirty pet paws or spilled drinks a breeze.  Using a pH-neutral cleanser and avoiding harsh products like ammonia and bleach will help preserve the integrity of your finish.  Harsh cleaners will degrade the finish and react with the concrete.

Repairing concrete is easy as pie too, with the right tools.  A properly finished and well maintained concrete floor should last between eight and fifteen years.  Sometimes, no matter how well-loved the floor may be, repairs will need to be made.  The extent of the repairs will depend on whether the concrete surface issues are structural or aesthetic.  Preparing the area for repair is an important step.  All cracked and flaking bits of concrete need to be removed from the surface area. The original sealant will need to be removed.  Dust, debris, and oils all need to be removed prior to starting any repair work.  If you are repairing a crack in the concrete, it is important to remember that concrete shrinks, and your current concrete floor has already completed its shrinking cycle.  You will want to ensure any filler you use to repair the cracks is a low shrinkage filler to ensure bonding does not fail.  Once the crack(s) are repaired, treat the concrete surface again with whatever abrasive technique is proper for your particular flooring to roughen it up, and then reseal the floor and polish until it is as shiny as you want it.

Prevent Further Issues for Long Lasting Finish


In order to maximize the durability of your concrete surface, make sure to maintain it regularly.  Removing and resealing the surface every few years will help prevent cracking.  Ensuring you are not using harsh chemicals to clean your floor will help preserve the sealant and the shine.  As the sealant is the top section of your flooring, this is where several eye-catching issues may arise.   If you are doing the prepping and finishing the floor yourself, make sure to follow all manufacturers’ directions regarding sealants.  Many issues, for example, bubbles in the surface, will become non-issues when you read the manufacturers’ instructions and learn the limitations of the product you intend to use.  Preventing problems is much easier and less costly than having to solve problems.

The One Man Polyurea Pump

With the popularity of concrete in modern construction practices, every concrete worker is familiar with the control joint, whether for walls or for flooring.  Control joints are a necessary part of concrete work.  As concrete ages over time, it shrinks.  That shrinkage leads to cracking within the slab of concrete.  While the cracks are inevitable, they are manageable.  If not managed with properly placed control joints, the cracks are unmanageable and difficult to maintain.  This is where control joints come in to save the day.  Control joints act as a planned crack to ensure the cracking is straight and manageable. The control joints work by filling the joint space next to a specific slab of concrete with the right filler that will expand as the concrete shrinks, allowing the concrete to maintain its form and cover the same amount of space, without unmanageable cracking.  These joints are a necessary part of concrete work and must be planned for and spaced out accordingly.

There are two industry-standard types of joint fillers:  epoxy control joint fillers and polyuria control joint fillers.  Semi-rigid epoxy fillers are easy to use, have a flowable pour, and may be applied with a bulk gun or a dual component pump.  However, polyuria control joint fillers appear to be the better option of these two fillers.  Polyruea fillers have the same advantages as the epoxy filler, but also are fast-setting, which allows for a quick shave making them perfect for caulking or repairing existing cracks.  Another plus of the polyuria filler is that it can be made in a multitude of colors.

How Does a One Man Polyurea Pump Work?

Now that we understand the benefit of the polyurea filler for our concrete control joints, we need to understand more about the application of the polyurea filler.  Just like the epoxy filler, polyuria filler can be applied manually or with a dual component pump.  Dual component pumps are necessary for the chemical reaction to take place to form the polyuria.  Specifically, the chemical reaction creates the polyuria through the mixture of a resin component and an isocyanate component (often a soft block prepolymer).

The One Man Polyurea Pump allows a single person to manage the pump with both of their hands managing different aspects of the filling operation.  One hand controls the pump’s position.  The other hand dispenses the joint filler with the other.  The user must first premix any necessary polymers and then ensure the correct items are placed in the correct poly tanks.  Cross-contamination is a real issue and needs to be avoided.  Once the correct materials are placed in their respective poly tank, the user should conduct a test spray through the manifold to ensure the stream is even and equal. If that test is even and equal, then the static mixing tip should be added to the manifold .  Once the static mixing tip is added, applying a test strip of polyuria to a piece of cardboard will allow the user to ensure the cure time is also proper. As the test cures, discard the static mixing tip and pump grease into the fittings of the manifold to prevent any cross-contamination.   After the test cure is deemed correct, the mixing tip should be replaced with a new one and the joint filler may then be applied.  It is essential to maintain the cleanliness of the pump to ensure it works properly for you during the next use.

Why is it Better Than a Traditional Pump?

The benefit of the One Man Polyurea Pump comes down to efficiency.  This pump allows one person to handle the task of joint filling while other members of the work crew focus on other facets of installing or repairing concrete.  Traditional pumps would require multiple people to operate.  One person would handle the application, another person would manage the pump position, and potentially a third person would manage the levels in the poly tanks.  Not only does the work crew become more efficient, but it is also cost-effective for the business owner as the cost of labor for the business decreases by using a one-man pump as opposed to the traditional pump.

Features of U.S.SAWS One Man Pump

U.S.SAWS features an industry-leading One Man Polyurea Pump with its SX20550 model.  This pump is a prime example of why the one man polyuria pumps are essential to a concrete working crew as it is perfect for single person operation.  The pump is equipped with a T handle that allows the user to easily guide the pump during the application process by knowing precisely where the pump should be to avoid wet floor joints.  When moving the pump to a new position, the attached waste bucket provides a place for the mixing tip to drip instead of on the floor.  There is also storage for a battery or generator as needed.  The poly tanks hold a volume of 6.5 gallons, and are semi-transparent to allow the operator to monitor fluid levels.  The SX20550 also comes with an enclosed box that is perfect for tool storage.  For the operator that requires something different from the standard 1:1 component ratio, U.S.SAWS does offer a 2:1 component ratio if needed.
