Keep Your B-Side Going

The B Side, in general, is less likely to cause contamination in the screens. As a result, B Side screens are often neglected.

One possible cause of B Side pressure loss is the collection of paint chips over time. Spray foam drums are recyclable and during the recycling process, some of the drums are repainted inside. Over time, the B component can soften the paint in the drum, causing it to flake off and collect in the Y-filter assembly – restricting flow to the machine. Making the Y-filter assembly a priority to clean can help prevent the collection of paint chips.

Check your hose temp at multiple points

When I find my equipment is spraying just right, I grab a pocket thermometer. With a variety of elements including sun and fluctuating temps outside, that’s what I use to maintain the temperature between my gun and proportioner.

I always stick a pocket thermometer at the halfway point of my hose, so if there’s 200 feet I stick it in the sleeve at 100 feet. This way, if the material sprays a little off, I just check that thermometer to ensure the hose is the same temp all the way through.

SprayWorks Equipment Group Provides Equipment, Materials and Training at the Waverly Hills Sanatorium

Louisville, Jefferson County, Kentucky: The Waverly Hills Sanatorium is a five story historical monument estimated around 800,000sf and well known for its historical past as a hospital to accommodate tuberculosis patients and is also deemed as the most scariest place on earth.

With its horrifying historical past, the Waverly Hills Sanatorium has been popularized on paranormal television as being one of the most haunted places on earth. The Waverly is visited by Paranormal Investigators on a daily basis.

Remove moisture from your drums

The “A” component, while in the drum, will react with atoms in the air resulting in the formation of crystal like skin structures. The “A” material should be sealed properly to limit the potential of these formations that if allowed to form will contaminate the liquid. Contamination may make the liquid impossible to process, requiring disposal and wasting of the product. Once the drum is opened, the air needed to replace the displacement of the “A” material being removed should be dry. This is achieved be either low pressure nitrogen being let in the drum as the material is displaced or filtered through a desiccant dryer.

Electrical Connections

Often overlooked when owning and operating spray foam equipment, is the electrical system.  When transporting to and from projects, the spray equipment takes its share of bumps and vibrations that can loosen electrical connections. I recommended rechecking all of the electrical connections at least once every three months. Weak connections can prematurely short circuit or shorten the life of the electrical components.

Best Tool to Have

As Spray Foam Technicians, we recommend one tool you should have on hand that can keep you and your crew up and running. When you suspect that you may have an electrical issue and need to contact a tech for help, one of the first things you may be asked is to confirm voltage’s through the spray system. Having a Multi-Meter on hand in your spray rig will help you to easily determine the answers you need to get your system up and running asap.

Use the Correct Mixing Chamber & PCT Combo

AP-EXWhen using the AP-EX extension gun in 16” on center stud wall type spray application – try using PMCs – 00X Mixing Chamber and PCT combination. (PN# KT-814-00X) Set your spray foam machine around 1,000 PSI on you’re A and B gauges. This will allow for further extended control of the AP-2s quick change mixing spray head.

Inspect Your Hoses

Over a short period of time, ISO material can accumulate on the pump – preventing the equipment from working correctly and causing potential damage. A quick daily inspection and removal of crystallization can prevent costly down time and will extend the life of your pump.

Follow this daily check with inspecting the bottom foot valve housing from potential obstruction. Lastly, color code the transfer pump ‘red’ for isocyanate and ‘blue’ for resin.

The Automated Spraybot:

The Machine that is Revolutionizing
the Spray Foam, Coatings, and Polyurea Industries

It resembles a Mars Rover Robot, except that a spray gun is mounted on this motorized mobile spray machine. Introducing the latest innovation in spray coating equipment: The Spraybot, from Sprayworks Equipment Group.

Jim Davidson, President of Sprayworks Equipment Group, LLC in Canton, Ohio has invented a new automated spray application machine that has been patented as the Spraybot. This roving machine is designed to evenly apply spray foam, polyurea, or other coating materials to roofs, bridges, decks, and other large horizontal surfaces. Interestingly enough, automated spray machines are finding a place in floor-coating industries that require the application of elastomers, polyureas, epoxy, and other types of coating materials.
