4 years ago I applied Gaco Roof, coats to an Office Building flat roof and have zero leaks since that time. This saved me $30,000 compared to having a new roof installed. The roof itself was only 7 years old when I applied Gaco Roof. but due to ponding water and harsh Florida heat and UV, the roof already looked shot and was leaking. I have now used Gaco Roof on 4 flat roofs to great results. I also tried big hardware store lower cost substitutes on 2 flat roofs. Those product utterly failed 1 to 2 years. Yes, I pressure washed my roofs clean before using Gaco Roof and followed their simple installation instructions. Excellent product.
I've seen this only once, and it was with closed cell foam, but I've heard of it happening with open cell foam, too. I don't know the details, but I've heard it could result from a bad batch of chemicals, improper mixing, or too high a temperature. Whatever the cause, it's not a good thing. The photo below shows how the spray foam pulled away from the studs. A little bit of uninsulated area like that adds up to a lot of heat loss/gain when the whole house has that problem, as it did here.

We have a 22 year old home located in southeastern georgia where the humidity is very high. In the past 2 weeks our floors have started buckling all over. We have a vented crawl space and the old insulation is drooping from moisture and the wood is wet. We are debating between the "encapulation" method or the spray foam method to repair this issue. Which would you recommend? Insulation Spray Coating

Thermal barriers are defined in building code as 1/2-inch gypsum wallboard or any material that is as equally fire resistant as 1/2-inch gypsum wallboard. The gypsum wallboard is known as a prescriptive thermal barrier. Materials are tested in a 15-minute fire test in order to determine whether or not they are equal in fire resistance to the 1/2-inch gypsum wallboard. If they are, then they can be used and counted as the equivalent of gypsum wallboard.


As discussed, many closed cell (and even some open cell) foam sprays do not need additional layers to serve as an ignition barrier. It is possible to use these spray foams, and leave them exposed in attics and crawl spaces. Additionally, you can use alternate assembly spray foams with intumescent coats and leave them exposed in an attic or crawl space without the use of an ignition barrier. In order for these methods to be accepted by code officials, the spray foammust be sprayed in the same exact manner they were in the assembly test in the laboratory.
The problem you saw with the closed cell foam pulling away like that is due to the heat of the foam was to hot. It was actually curing out and making foam before it could adhere to the wood. The installer wasn't reading his foam correctly. He should of stopped and turned down the heat on his hose temp. Also installers have to be aware that as the sun rises and the temp in attics rises the subtrates get hotter as well. This will cause the installer to adjust his heat when installing the foam as the temp changes thru out the day.   Spray Coating Services
The second type of barrier that prevents insulation from catching fire is called the ignition barrier. Ignition barriers are a lower standard to meet than a thermal barrier. Additionally, several different materials can meet the definition of an ignition barrier. Now that we have established the code jargon for spray foam barriers, we can look at each type in detail.

Spraying paint with compressed air can be traced back to its use on the Southern Pacific Railway in the early 1880s[1] In 1887 Joseph Binks, the maintenance supervisor at Chicago's Marshall Field's Wholesale Store developed a hand pumped cold-water paint spraying machine to apply whitewash to the subbasement walls of the store.[2][3] Francis Davis Millet, the decorations director for the World's Columbian Exposition in Chicago in 1893, used Binks and his spray painting system to apply whitewash consisting of a mix of oil and white lead to the buildings at the Exposition, taking considerably less time than traditional brush painting and tuning it into what has been called the White City.[4][1][3] In 1949, Edward Seymour developed a type of spray painting, aerosol paint, that could be delivered via a compressed aerosol in a can.


Prodex reflects 97% of the radiant energy (primary source of heat flow) that strikes it - Which also protects your animals from Black Globe Effect. Prodex also reflects back the heat inside your steel building. Each unit of radiant heat energy that is reflected away from your barn in the summer, and each unit that is reflected back during the winter, means less operation of your heating and air conditioning system - Less wear and tear on your equipment - Less money you pay in utility costs.

I applied CMX on my wife's car and my car and had odd results. See pic. I ended up with little white beads that formed when I sprayed CMX on car, wiped it to a haze, but not completely off. After about 2 minutes I then began to wipe CMX until the haze was gone. However, oddly, after letting the product dry (but not yet wiping completely off) it began to form white little beads (possibly residual). What a pain as these beads landed in all the window crevices, etc. It's like when you have a bad wax that leaves dust. I had to use a can of compressed air to wipe the bead out of the crevices. I was thinking that allowing it to haze would allow CMX to bond to the paint better. After getting the beads cleaned up I tested again and spray CMX on, then wiped completely dry. No beads.

If you're chemically sensitive, it's probably not a good idea to get it installed, but it's also not a good idea to breathe musty air from the crawl space either. In addition, your house and its contents are made of lots of materials that affect your indoor air quality. If you're really concerned about this, hire a company to test your air and tell you what you can do about it.


Prodex eliminates the moisture (condensation) from forming on the metal sheeting. It does it by making the temperature of the metal sheeting on the building approximately the same on the inside as the outside. When the heat or cold from outside comes through the metal skin it hits the outside aluminum facing of Prodex and is reflected back upwards through the underside of the metal sheeting. This process keeps the metal sheeting temperature consistent on both sides. In addition, the inside layer of aluminum in Prodex reflects away the heat (heater) or cold (air-conditioning) from inside the building, from getting to the metal skin. This also helps in preventing condensation.

Most electric powered airless pumps have an electric motor connected through a gear train to the paint piston pump. Pressure is achieved by stopping and starting the motor via a pressure sensor (also called a transducer); in more advanced units, this is done by digital control in which the speed of the motor varies with the demand and the difference from the pressure set-point, resulting in a very good pressure control. Some direct drive piston pumps are driven by a gasoline engine with pressure control via an electric clutch. In electric diaphragm pumps, the motor drives a hydraulic piston pump that transmits the oil displaced by the piston, to move the diaphragm. Insulation Spray Coating
Mass-produced material is loaded on a conveyor belt where it is fed into one of these flatline machines. Flatline machines are designed to specifically paint material that is less than 4 inches (10 cm) thick and complex in shape, for example a kitchen cabinet door or drawer front. Spray guns are aligned above the material and the guns are in motion in order to hit all the grooves of the material. The guns can be moved in a cycle, circle, or can be moved back and forth in order to apply paint evenly across the material. Flatline systems are typically large and can paint doors, kitchen cabinets, and other plastic or wooden products. Spray Coating Services

A spray booth is a pressure-controlled closed environment, originally used to paint vehicles in a body shop. To ensure the ideal working conditions (temperature, air flow, and humidity), these environments are equipped with ventilation, consisting of mechanical fans driven by electric motors, and optionally burners to heat the air to speed paint drying. Toxic solvents and paint particles are exhausted outside, possibly after filtering and treatment to reduce air pollution. Prevention of fires and dust explosions is also a high priority. In order to assist in the removal of the over sprayed paint from the air and to provide efficient operation of the down-draft, water-washed paint spray booths utilize paint detackifying chemical agents.

Thank you, Allison. We have a split system unit (actually 5) with the heat being propane. The foam guy said that it needed ventilation, so completely sealing the attic wouldn't be a good idea. It sounds like you are saying that the systems need to be vented out of the attic or replaced with some type of closed system. But I shouldn't bother spraying if the plan is to leave the soffet vents open. Is that correct? Spray Coating Services


Closed-cell (aka two-pound foam) is denser than open-cell at about 2 pounds per cubic foot. Its R-Value is between 6-6.5 per inch. As a result, this kind of foam is much more expensive than its counterpart. The reason closed-cell doesn't need a vapor retarder is because it already has one. It's permeance is 0.8 perm, which means it can handle cold climates without the use of an additional board or drywall. Closed-cell uses hydroflurocarbons (HFCs) as part of its makeup. However, this material has been known to have a high global warming effect. If you want a green insulation solution, this is not the material to use. A way to avoid this and still use closed-cell is by installing it alongside fiberglass batts. Coating Services

These spray foam insulation kits are quick to learn and simple to use. They’re designed to be easy so you get results the very first time you spray. Thorough Instructions, 24/7 Product Support, and videos make it easy to install. Spray Coating Services
Sean, thanks for jumping in and answering John's questions. About choosing the right foam, I intentionally avoided the open cell vs. closed cell foam debate. I did this partly because it's worthy of an article all by itself, but mainly I didn't include it because, despite all the warnings the two sides issue about the other, I've never personally seen a problem caused by using open cell where they should've used closed cell or vice versa. I'm sure things like that happen; I just haven't seen it yet. Coating Services
