Transfer Hose Size from your Pump to the Proportioner

I got an email today that was a good one.  We sell our stainless braided, transfer hose that runs from your drum pump to the Proportioner. Our line is only 3/8" ID and the customer was concerned because his OEM hose is 3/4". He was concerned that the hose would not be able to handle the fluid flowing to the proportioner.

The Graco, IPM and Gama pumps all have the same flow rate of 5gpm (50 lpm). Thats a total flow capacity of 10 GPM (100 LPM) that can go to your propotioner.

If you spray a standard 01 (AR42) chamber, your spraying at 1.2 GPM (10.20 LPM) And that flow rate is if you hold the trigger down and never release it.

SO, we have 1.2 GPM (10.20 LPM) total, but split into to fluid lines = .60 GPM (6 LPM)

I think I can Pee that hard after a few beers at the Hofbrauhaus House in Munich. In fact, I feel fairly confident I did.

I also noticed that the pressure rating on the OEM hose I saw was 3000psi.  Your 2:1 ratio pump is only 200psi if your air inlet pressure is 100psi. (1:1 ratio and 2:1 ratio means inlet air pressure x1 or x2 is what the pressure is going out of the transfer pump)

Bottom line - Why do you think you need a 3/4", 3000psi hose to  flow .6 GPM at 200psi a distance of 6 feet from the drum? I understand that cold weather makes the fluid thick and harder to flow. Very true, but your fluids are supposed to be at 70F minimum prior to hitting the proportioner heaters.

The industry standard flow rate for 3/8 Hydraulic line is rated at 7 GPM and for 3/8 pipe is 12 GPM.  Don't forget, you're all flowing through 3/8" heated hose and drop to a 1/4" whip at the gun. 

Choosing an Email Name or an Ecommerce Store Name

This may be a little off topic, but I just finished an interview that will be published in a few weeks were I was asked about problems in E-Commerce (Web Stores).

It brought out several issues we have faced in our business and what I see that others do, so I thought you would enjoy the subject.

Lets deal with email addresses and tie it in with an E-Commerce site. When choosing an email, you want to keep it simple and short. Ask yourself if you're going to have to spell out your address every time you give it and if its easy to understand with a poor cell connection. We are in the business of manufacturing parts for the spray polyureathane foam industry and provide a good 1 stop shopping experience. We opened SPF Depot, we thought this was easy, but it turns out that a small percentage don't realize that SPF is an industry term and we do get hits for suntan lotion. At times I have had to spell it out as Sam Paul Frank D E P O T and I can hear them repeat and writing SAMPAULFRANK... We have some people say De Pot ? as in "get off the pot, my bran muffin and Starbucks just kicked in". Sure, we all go to Home De Pot to buy plants. With that said, is easy for the majority. Then we get asked "is it all in capitals or lower case?" It makes no difference at all. I just list it this way so its easy to see. Email and web addresses can be enter in all caps, all lower case - it doesn't mater. But, it is fun at times to say that we capitalize every other letter.

Using your company name is a great way to make it easy, unless your company name is Spray Foam Insulation and Coatings Systems of Southern "My State". Would you want to have to type that out on your cell 20 times a day? Then you add to that your names to your email address:  Spell that out 20 times a day and see how many emails you never see because they misspelled it or left a letter out. Avoid hyphenated names, underscores, misspelled names and using an actual number (2-xpray_Pro's).

In case you have been living in a cave, we live in a time with people suffering from attention deficit. People live on 3 word tweets and 4 letter abbreviations due to not being able to focus much further than a simple Tweet. In fact, they prefer to tweet over sending an email or just picking up the phone. Look at largest businesses out there MAC, iPhone, GMAC, ATT, even McDonalds is now McD's. They use short names and abbreviations for a reason. 

Try to keep it simple, short and easy to understand. For E-Commerce sites lets just look at names. Having a big company name as the one I just mentioned is not uncommon, but you need to chop it down some for the web site and your email address. A huge problem is some do not pay attention to the name they choose and huge corporations have made bad choices on names. Chevrolet came out with the Chevy Nova years ago and when they tried to market it in Mexico, they noticed the sales where poor.  Nobody realized that NOVA in Spanish is No Go and the sales reflected the name they chose for their No Go car.

Now lets look at really dumb names. A cell company - Who Represents with a web address In case you don't know what to buy for that special woman. A specialty store that makes pens - Pen Island with a web address of Great place if you're a real jerk. Speed of Art - web address is Never had one of those. The worst name of all Master Bait and Tackle web address is   Of course the company Big Ass Fans has done very well.

Think about your company name, but think harder on your email address and web store address before you invest big dollars and discover a problem. You'll give those out every day and you'll type it out 20+ times a day. Ask yourself if you want to type that on your cell several times a day. Don't forget to check out trademark infringements by trying to use a like company name or a logo. 3N of China lost big time for using the close copy of the 3M logo and colors. You can even try to Google the name you pick and see what pops up.

Pick a good name - I hope you have it for many years.

SPF Depot Foam Release & Solvents Now in Canada

Winroc first began with a single store in Winnipeg in 1971, and for nearly half a century, the company has continued growing to serve customers all over Canada and the United States with more than 40 outlets all across North America. As a major supplier to the construction industry, providing products for contractors as well as individual, do-it-yourself homeowners, Winroc has long prided itself on the ability to obtain and bring to market the finest-quality products and tools for use in the wall and ceiling building trades.

Top American manufacturer and supplier SPF Depot is pleased to announce that, as part of this ongoing effort, Winroc is now offering a variety of its parts and solvent products. These items are geared toward those involved in the application of spray foam and polyurea coatings. SPF Depot features original manufacturer equipment (OEM) and parts as well as its own branded products, some of which are proprietary and found nowhere else. SPF Depot is known not only for high-quality products, but also affordable prices.

One-of-a-Kind Solutions

Anyone involved in the application of spray foams or polyurea coatings, whether for walls, ceilings, rooftops, insulation or truck bed liners, knows the troublesome nature of overspray and leftover, cured product on tools and hoses. SPF Depot has developed and manufactures a proprietary product for protecting tools and safety equipment from the debilitating effects of overspray: SPF RELEASE. This is a releasing agent that, once sprayed on a surface you want to protect, allows you to simply wipe that surface clean when desired.

An example is plastic face shields used during spraying operations. Rather than tossing out and replacing your costly face shields regularly when they become unusable as a result of becoming covered with overspray, spraying them with SPF RELEASE prior to use allows them to be simply wiped off when necessary, avoiding the need for continual shield replacement, thereby saving a good deal of money. SPF RELEASE can be used to protect whatever you need from overspray.

Other Great SPF Offerings

For items that have already been covered with spray foam or polyurea that has dried and cured (having not been pretreated with SPF RELEASE), SPF-6 is an environmentally friendly solvent that dissolves cured product from spray guns in about 30 minutes, without the need to add heat. SPF-5 is a hose and system flush agent. ISO REMOVE is another available product made specifically for the removal of cured ISO.

Other SPF Depot products and parts will be available, especially if users request that their local Winroc outlet stock the items they must have. Once you use SPF Depot parts, you’ll quickly realize that these are the very best products of their type available anywhere.

How to Properly Maintain Spray Foam Gun Equipment

Spray foam gun equipment has become more popular as the number of uses has increased and SPF tools have become more affordable. While spray foam guns have many commercial and industrial applications, the equipment itself is extremely delicate and requires constant cleaning and attention. It is important to maintain your SPF equipment in order to ensure the longevity of your tools and the quality of your projects. Once your equipment has become damaged by careless usage or lack of cleaning, certain parts may not be retrievable and other SPF components may be damaged.

One of the most popular uses for these guns is the application of spray on coatings including polyurea coating used for truck bed liners, roof coatings, and many other uses. Polyurea is made from a synthetic resin blend that can clog your spray gun equipment if not properly maintained. If this resin or other types of spray foams become crystalized inside your equipment, it can begin to compromise the quality of future projects and render your spray foam tools useless.

Here is a list of some of the most important Do’s for properly maintaining your spray gun equipment to avoid things like cross-overs, leaks, and other performance shortcomings:
  • Clean the main port of your mix chamber when your pattern starts to fluctuate. Use the proper size drill bit or use our Tip Cleaner with the wires that don’t break. Closed cell foam gums up chambers faster than the open cell. 
  • You can flush your gun at the end of the day with our SPF-5 Hose/System flush.
  • Follow our procedure on proper shut down at the end of the day and inject our grease to form a seal around your chamber. Our white grease and those from OEM’s work best. Some other brands dry up and will clog your gun. 
  • Keep your gun and equipment clean. Nothing makes a contractor look worse than a ragged out gun and a trailer that looks like an ISO explosion. Use our SPF-5 or even WD-40 if you want to wipe off some chemicals that are still in a fluid state. Our SPF-ISO Solvent will melt the cured ISO. Wet a paper towel and place it on your gun and you can wipe it clean the next day. 
  • Read our start up procedure to check your gun PRIOR to hooking up you fluid lines. 

And, here is a list of Don’ts you will need to avoid in order to keep your equipment working at peak efficiency:
  • Don’t soak your rubber o-rings in solvent. They have a natural lubricant built in and solvents dry them out. That’s why your o-rings break when you try to remove them.
  • Don’t shoot carburetor cleaner, brake cleaner or acetone into your gun. These are solvents and will gum up the system. If you have to shoot something into your gun – use WD-40. Nothing in that will hurt your seals.
  • Don’t clean your parts without removing the o-rings.
  • Don’t just shove a drill bit into the chamber ports. Be gentle and twist the bit as you go. That’s how you break bits off. We can remove broken bits for you.
  • Don’t keep spraying when you notice a bad pattern or no purge air coming out. You’ll only make a simple problem worse – very fast.
  • Don’t over sand on your chambers and side seals. This causes the parts to become a cupped surface rather than flat. Use 1200 grit and DON’T sand in a circle motion. Pull or push the part in a straight line with equal pressure. Pushing hard on the front of the chamber to remove scratches causes the surface to slope. If you can feel a scratch with your fingernail – it will leak when you hit it with 1000+ psi in your gun. We can re-surface you chambers and lap them to get them back to a factory finish.

These steps and others can help ensure the longevity of your equipment and quality of your finished projects. If any of your spray foam gun equipment does become clogged or damaged, SPF Depot sells all parts and accessories needed to clean, repair, and maintain your SPF tools and equipment for years to come. Remember, using unapproved parts with your SPF tools can cause irreversible damage to your equipment and may void any warranties.

Standard vs. Coalescing Air Filters for Spray Booth Systems

Anyone familiar with spray foam tools knows the importance of using the proper air filters for your
SPF equipment. Spray foam filters are designed to remove airborne contaminants including pipe scale, rust, pipe dope, and other harmful particulates from your system before they damage your equipment or compromise your work. There are two main types of SPF filters, standard filters and coalescing filters, and their use could not be more diverse.

With your standard spray foam air filter, air flows into the inlet port through a deflector plate which creates the centrifugal action necessary to remove any contaminants. Filter shrouds assure the proper swirling action occurs and that air does not pass through the filter before large particles and liquids are removed. The baffle separates the lower portion of the bowl where the removed liquids and particles collect and do not re-enter the airflow system. These particles and fluids are drained from the system while clean air passes through the supply line.

Coalescing spray foam air filters remove suspended liquids including oil and water in the same way standard filters work, but are used for removing aerosolized fluids not removed from a standard filter. The most common filter assembly for this type of system consists of a 3-unit combination of a Filter, Regulator, and Lubricator (FRL). The clean airflow passes through the coalescing filter into the regulator which sets the appropriate air pressure. Then, the air passes through the lubricator to provide a light oil for lubricating O-rings and seals throughout the air system. It is important to place the filter first in order to keep the diaphragm on the regulator clean to ensure constant control and a longer life.

It’s best to hook a large standard filter directly to the compressor tank to remove any rust and water prior to entering the FRL. If your SPF system uses a refrigerated dryer, put the lubricator section after the refrigerated dryer to avoid plugging the system with oil and make sure to add a coalescing filter to this section, as well.

Using the correct filters for your SPF system will ensure that your parts last longer and your work is never damaged due to equipment malfunctions. Many SPF parts are delicate and require airflow free from particulates in order to function properly. But, with a combination of proper filter use and diligent cleaning of all equipment, SPF tools can last years without replacement.

Above is a picture describing how to properly plumb a line to prevent rust, water and other contaminants from entering the supply line with the use of a Drip Leg. The drip leg drops below your other supply line to allow fluid and particles to accumulate in the lower section so you can blow it out when you open the ball valve. Bring your supply lines off to the side, or over the top if running horizontally. That prevents the water from free flowing directly to your supply lines. Always have a ball valve to close the air supply so you can work on each leg without having to kill the complete system. Shown here is our filter/coalesce/regulator assembly. The lubricator is further down line. We use an inline lubricator at each transfer pump. Screw this directly to the pump and screw the supply line onto this. As air passes through, the oil is atomized to an aerosol and goes into the air section of your pumps. This provides clean/dry air from your filters, and then lubricates the seals in the pump. Eliminating the water and adding a small amount of oil will triple the life of your air motors. This is also a must have for your drum mixer. Water makes rust and the rust eats the air motor seals. The lubricator only hold 1/2oz and we use the TSL fluid. If you have to fill it 1 time a month – you’re doing fine. Filling it every day provides too much oil; this can gum up the system.

OSHA Inspections are now targeting the SPF Industry. Be Prepared. just published an interesting article that everyone needs to read and take proper action on.

OSHA's Directorite of Enforcement spoke at the SPFA convention in 2015 and noted that the top violations in the SPF field are:
1. Improper or lack of ventilation in the work space.
2. Slip/fall issues related to becoming entangled in hoses.
3. Exposure to trimming foam.
4. Lack of PPE (Personal Protective Equipment)
5. PPE that is damaged and not cleaned - DAILY
6. Hazard Communication (MSDS sheets, proper signage in the work space, controlled entry point)
7. Flammable Liquids not properly stored.
8. Electrical wire violations

As of December-2014, OSHA has conducted 386 inspections and cited 1351 violations. Fines on violations can start as high as $10,000 each. This makes it more important than ever that you are familiar with  the PPE program, Fit Test procedures and simple code corrections you can make that are very inexpensive to do.

Here is a link to the OSHA directive on the SPF industry and the concerns they have with exposure to Isocyanates:

Here is a list of the top violations found and the OSHA code you need to become familiar with.
1:  OSHA 29 CFR 1910.134 Respiratory Protection:

2:  OSHA 29 CFR 1910.1200 Hazard Communication:

3:  OSHA 29 CFR 1910.132 PPE Equipment:

4:  OSHA 29 CFR 1910.107 Flammable Liquids:

5:  OSHA 29 CFR 1910.305 Electrical Wiring:

If you are uncertain on what you need, there are consultants that are familiar with the OSHA reg's and they can come to your work place and point out what needs to be done in order to comply. The consultants do not fine you or write up violations to report to OSHA. They are truly there to help you. As mentioned in the Sprayfoam article, you can call OSHA and ask about onsite consulting for small/medium businesses. I equate that to calling the IRS and asking for an audit to help you find improper book keeping procedures. I would prefer a private consultant and OSHA may be able to supply a list of them in your region.

We had a consultant come to our office to discuss the program. Some general violations people have are in the electrical section. Extension cords as a permanent for of power are not permitted. If you have extension cords tied up in your trailer or in your shop, you need to run conduit and have a proper junction box. Also, surprising - Power Strips are a big NO-NO. I know - everyone has a power strip with 5 cords plugged in. You are required to have proper junction boxes with an outlet for each cord to plug into. No power strips allowed. All electrical lines have to be in electrical conduit - not PVC pipe. Buy a steel cabinet for storing flammables in that is properly labeled and its best to not have a gallon can of gas in your trailer. MSDS books have to be current. MSDS can be confusing. Its required for everything you have in your trailer, but I have never heard of an MSDS for water and Gatorade, but we do have them for hand soap. Procedures for spills have to be documented for the dumbest of all people to be able to read and follow the procedure. Ladders have to be stored out of the way, secured to the wall to prevent falling or creating a trip hazard. For work sites, you need a controlled entry point, signage that clearly states its a restricted area that requires proper PPE equipment.

The list could go on forever. Bottom line is - you need to be familiar with the code and follow it.
