Thickness is controlled in three ways, and we utilize all three.

Firstly, yes, the sprayer needs to have a grasp on how much the machine sprays out per minute, per pass at the sprayers normal motive rate, what the job spec calls for, what needs to be built thicker, etc. This is done much like a BUR mopper would know if his hot is going down at the proper flow rates. You have to be at the proper application temperature, and the mopper needs to know what he's doing.

Secondly, we know how much material has been ordered, is on the job, how large an area we cover with said amount of material, mark out this area, and app.ly the product. If we have left overs, then we go back and hit thinner areas and seams, flasahings, penetrations again until this area's material is accounted for.

Lastly, we use an elcometer mil thickness guage. This is an expensive tool. It measures how thick your coating is electronically.

Measuring a coatings, minimum thickness is the l.east of our worries in applying this awesome system.

Overspray.... Dont let it get on anything you dont want it on. Its that simple.

No seam tapes.... not needed. Instant set self-reinforcing. We can spray right up until it rains baby!

Unlike any of the elastomeric acrylics, the thicker you apply polyurea, the STRONGER it gets. So to build up at the flashings requires no reinforcement of any kind but additional spray.

Grumpy, have I ever gotten any samples in to your hands? If you were to sell this stuff, we travel.

If youre not an owner that can be on the job, I wouldnt recommend this system.

Extra thick with acrylics is not better. There is a point at which you are screwing the pooch by adding more material.

Three gallons of properly cured acrylic will pield about 27 dry mil per 100 sq ft. 3 gallons of polyurea will yield 48 dry mil per 100 sq ft. We will go up to 100 mil. Anything beyond this is overkill, in my professional opinion.

Aaron is this considered a coating or is it a roof system?

What type of Warranties are available and who backs them?

It sounds similar to the below grade or plaza deck -type systems that I have read about.

Is it Energy Star rated? How do you find it holds up to UV?

I typically stay away from field fabricated products for many of the reasons Grumpy pointed out. As roofers on the East Coast we seem to have enough working against us, having the membrane produced in a controlled environment rather than on the roof takes some of the chance for error out of the mix.

I am always up for learning about other products so if you have a link or something I'd like to check it out.

Show me how and who to market to and I would be willing.

I don't have any samples.

Ed, shoot me an email or call me at my office number. I will be happy nto get you some samples. We can go over the oparticulars also.

Maybe you, Grumpy and I can all get together and have some Dunkin Donuts coffeetalk. Remember the skit from SNL?

This tends to be a profitable arrangement for all of us.

It holds up to UV quite well if you use the aliphatic polyureas or aluminumized, copper, grey or black aromatic polyureas. Aromatics are better for long term durability, but if you want a UV stable color, aliphatics are needed.

There are some various specs on gaining Energy Star ratings. You can waterproof seams, fasteners, flashings, drains, etc with an aromatic polyurea, and go with a white acrylic @ 2 gallons per square for the required 70% aged reflectivity of the Energy Star rating. OR you could go with an aliphatic color stable white to achieve same.

The acrylic will wear like any other acrylic, but can be recoated after about 10 years with a pressure wash, primer, and acrylic.

VersaFlex guarantees their aromatic (40 mil) with an acrylic latex paint topcoat colorant if applied directly behind the polyurea application BEFORE the reaction is complete. This is must be done within 4 hours. It has to be done this way with this spec because the paint will actually cross-link with the polyurea since it is applied before the molecular cross-linking is completed.

Due to cost considerations, we generally apply an aluminumized aromatic polyurea/urethane hybrid at 48 mil ADFT that weathers to a light grey and provides a little over 50% aged reflectivity. We offer ten years on this system, and polyurea mfg warranties are also available.

Field processing is the only way that this system is able to be applied since it is instant setting (10-30 seconds for hybrids and 4-6 seconds for pure polyureas). You KNOW if youre off-ratio, and you have to stop immediately, clean up the faulty material, solve the proportioning issue, and continue spraying. If you mess this system up, its your fault 99% of the time, and therefore need a wealth of technical info, the right equipment, and spraying experience to get it right.

This is what we do.

Grumpy

Aaron you gave me a sample and a ball park price. Simply put, I can't afford you

Plus seiously I can't sell one product that I have only one installer for. I become too dependant upon that installer and if for some reason we ever break partnership I am left stuck holding the bag. You also bring up another point, I don't want any system where I'd have to be locked on the job. In theory I want multiple crews out working every day, that'd be impossible for me to be in 4 places at once, plus doing my sales and business management too. Impossible.

.....And that's where we come in.

You dont have to be on the job to know youre getting a quality job.

I am an owner operator so that you dont need to be one in order to get your customers a polyurea roofing system.

With what you already know and sell, you could easily sell this system at higher prices than mine. I am offering you a good value.

If our system does fail before your retirement, I can show you how to properly repair and maintain our system. You have intelligent roofing people. They can be trained for this aspect without expensive outlays.

It really is a win-win-win situation, Grumpy.

Grumpy

I prefer Javaman from Mad TV. LOL When he was popular I was working in a machine shop and took my saftey glasses and painted big yellow blood shot eyes on them.


Anyways we should have met at the CRCA show last week. Are either of you going to the AirVent seminar?
