Chopped Glass Emulsion - Still The Fastest!

And possibly the longest lasting retrofit you can install. This 29,000 sq. ft. roof done in 1 day. Tomorrow it gets aluminized emulsion - 2 days turnkey.

Weve been installing chopped fiberglass going on ten years now we recently had a metal roof we sprayed when we started hit by a tornado it was close to ten years old and the roof looked like the day we put it on it would have lasted another 10 to 20 years easily i was surprised at how good the chopped fiberglass looked no breaking down of the material.

We do some of the acrylic polymer coatings and they weigh about twice as much as that.

Did you come up with the idea of applying the emulsion with the glass like that? About 50 years ago we did some roofs with an emulsion and rolls of mesh: a product called "Adex". It worked well, but the same problem showed up. It was temperature sensitive and rain sensitive. Michigan is not a good state to do that type of process in.

Yeah, now I may be confusing emulsion's weight with 100LL avgas, but I think it's 8.69 lbs./gal. Divide by 2 because it's roughly 50% water and you get 39 lbs. + 3 lbs glass. It miust weight more than that per gal because the industry says it weight 49 lbs.

9 gallons of emulsion only weighs 46 pounds when it cures? Hey, if it works, why not?

Actually I sold my interest in Kold King last spring.

Sometimes we pressure wash but usually powerbroom. Emulsion has really good adhesion properties. We've done 31 million sq. ft. and I can't think of a single 1 that blew off.

Flashings - if they have splits and cracks we install a poly fabric flashing set in emulsion, then chop. If we're repairing hail damage we usually just chop.

Neat thing about the chopped glass emulsion system is it weighs only 49 lbs per SQR and it does not blister.

Thanks for posting the video. Read your posts for years about the product so it was interesting to see what it actually involves to apply it.

Do you power wash the old roof before you spray on the new roof? We do some coatings up here in Michigan, but realistically there are only about 50 days a year when you can actually coat up here. Rain, wind, cold all make the "coating" business iffy. How do you treat the flashings with that system. Just spray and let the glass re-enforce it? It is good that you posted the video as I have read about your system and never seen it.

Typical spec on smooth is 9 gallons of emulsion, 3 lbs. of chopped glass, 1-1.5 gallons aluminum.

It is water-based so it cannot freeze until set. We work 12 months here in Texas but we have to be more careful in winter.

Depending on outside temps and humidity, it will set up in 30 minutes to a few hours. The secret is to constantly look at what you sprayed 30 minutes ago, 60, 120. It turns from brown to black when it is set up enough to handle rain and looking at what you did an hour ago gives a good clue about when you need to call it a day.

No guy is running the machine - he just goes down periodically to switch 275 gallon totes. Typical crew is 3 men but we're running 6 on this job to beat the weather coming in tomorrow.

So how many gallons per square of emulsion do you use? How temperature sensitive is it? If it is freezing I am sure the water based emulsion would not set up before it froze. Rain would also be an obstacle. Just wondering. It looks very fast though. One guy holding the box of fibre, one handling hoses and one holding the screen for the overspray. I am sure one guy on the ground maning the pump. Interesting.

The existing roof is our chopped glass roof that was hail damaged. Yes, that is fiberglass gun roving coming out of the box that will hold about 14 SQRS worth. The Kold King chopping gun chops it into 1/2" strands and blends it midair with clay emulsion. Same process used in making boats, RVs, tuns, except we blow in emulsion rather than resin. Building "felt" into the asphalt as it's sprayed.

We just replaced one I installed in 1986, due to hail. It had another 10-15 years of life in it if not for the hail. They last a long time if done right.

Was that sprayed over urethane foam? Do you do anything over the flashings? Was that the fibre-glas coming out of the box that the third man was holding?
