Personal protective equipment (PPE) use: PPE must be used when handling spray paint materials, particularly PPE that offers protection to the skin. Some of the essential personal protective equipment are overalls with a hood, protective goggles for the eyes, half-mask respirators, and single use nitrile gloves. One of the most essential types of PPE is respiratory protective equipment (RPE). Nevertheless, basic RPE does not offer ample protection from the negative effects of isocyanates in human tissue. Paint products containing isocyanates must be handled while donning an air-fed RPE that has a 20 or higher APF (assigned protection factor). Air-fed respiratory protective equipment needs extra attention since they provide breathable air to the user. When in use, measures must be implemented to prevent contamination of the air supply since there is a risk of harmful substances entering the intake valve if it is not positioned outside of the spray area.
I applied the Gaco 100% Silicone Roof coating to a slightly-sloped, metal porch roof. My leaks have stopped, and it looks like they are gone for good. I followed the instructions, and it appears the product made a perfect bond to the roof. What a terrific product! I'm glad I made this purchase, and that I didn't settle for a cheap, metal coating from the local outlet store. Coating Services
Hydraulic and air-powered airless pumps have linear motors that require a hydraulic pump or an air compressor, which can be electric or gasoline powered, although an air compressor is usually diesel powered for mobile use or electric for fixed installations. Some airless units have the hydraulic pump and its motor, built onto the same chassis as the paint pump.
When do you need an ignition barrier? According to the IRC and IBC, an attic or crawl space needs an ignition barrier over the spray foam if the space can be accessed but will not be used for storage or auxiliary living space. You don't need an ignition barrier if the space cannot be accessed without cutting into it, if it is not connected to other spaces, and if it does not communicate with other spaces.
What do you mean by "our AC units require fresh air ventilation"? Fresh air doesn't come from the attic. If there's an atmospheric combustion appliance in the attic, such as an 80 AFUE furnace, then you shouldn't be encapsulating the attic anyway. If that's the case, you don't want spray foam on the roofline at all. You can either change out the furnace to a sealed combustion unit or do your insulating and air-sealing at the flat-ceiling level. Spray Coating Services
That’s $58.3 Billion dollars. That’s roughly how much money we wasted in 2010 in the US according to the Department of Energy because of air leaking out of our building envelopes. If your building leaks energy, you’re paying more for energy than you need to. Clearly you’re not alone. If you’re ready to claim your share of the savings, it’s quicker and easier than you think.

Condensation - It can seem like a tropical rain forest inside an unprotected metal building. It's worse on those days where there is a greater contrast between temperatures at night vs. day. The morning sun hitting the cool sheeting will create a drip. A temperature difference between outside and inside your building creates condensation - Similar to what happens when you leave a cold can of beer outside on a hot day. Insulation Spray Coating
Like HVLP, low volume low pressure (LVLP) spray guns also operate at a lower pressure (LP), but they use a low volume (LV) of air when compared to conventional and HVLP equipment. This is a further effort at increasing the transfer efficiency (amount of coating that ends up on the target surface) of spray guns, while decreasing the amount of compressed air consumption. Insulation Spray Coating
Yes, absolutely. If you put spray foam insulation in a building, it needs a thermal barrier. That's what separates it from the occupied spaces. If there's a fire in the building, a thermal barrier keeps the combustible spray foam from the flames to increase fire resistance. The International Residential Code (IRC) and Internation Building Code (IBC) both include requirements for thermal barriers (and ignition barriers, too; see below). Coating Services
This is more common with closed cell foam, but it happens with open cell foam, too. Since closed cell foam has a higher R-value per inch, installers generally spray 2" in walls and 3" in rooflines to meet the energy code requirements of R-13 and R-19, respectively. (I'm not going to dive into the energy code here, but these numbers apply to many climate zones, the latter being allowed under the UA tradeoffs rule. See the Energy Nerd's blog on this topic if you want to argue.) Spray Coating Services
The drawback to spray foam insulation is it's been known to cause certain health issues such irritation of the eye and the gastrointestinal and respiratory tracts. Direct contact can cause inflammation to the skin, and some individuals have been known to break out in a rash on the arms, chest and neck area. Spray foam insulation has also been linked to a few cases of hypersensitivity pneumonitis. This condition can cause: Spray Coating Services
The guys who sprayed my attic were trained and certified, but I later found out, too late, that they had no experience and my attic was the first they'd ever sprayed. I was also never told to vacate my house for any length of time, and so I (and my pets) were in the house the day they sprayed and the entire time the off ratio foam was filling my home with horrendous vapors. The company kept telling me that it was a good job and I had nothing to worry about, even after I'd had 2 other experienced sprayers from 2 different companies visually examine the foam and confirm that large areas appeared to be off ratio. The 3rd sprayer from yet another company, was also outraged because the company who did my attic had failed to vacuum up all of the old cellulose insulation, and he also noticed areas where the foam was shrinking or pulling away, and this was not even 5 weeks after the spraying.

RE: my June 12 post...We went ahead and had the attic sprayed with a Soy-based product. Stayed in a hotel for 3 nites. Still smelled a little bad but that's gone away over time. I'm very glad we didn't use the other foam as even that much outgassing of a petrochemical could have sent my wife to the hospital. Unfortunately, the spray crew didn't speak English(at least not to me) and were kinda lazy, so they ended up spraying over some can fixtures from the kitchen below that were not insulation-contact rated. So I hired an electrician to come out, pull down the cans, pull out what he thought was an appropriate amount of foam to create a big enough air space and then re-install the cans. I billed the firm for the electrician plus an extra night we had to stay in the hotel and they paid, no questions asked. Guess they knew they had screwed up. Spray Coating Services

By heating the full-bodied paint to 60-80 °C, it is possible to apply a thicker coat. Originally the paint was recirculated, but as this caused bodying up, the system was changed to direct heating on line. Hot spraying was also used with Airless and Electrostatic Airless to decrease bounce-back. Two pack materials usually had premix before tip systems using dual pumps.
Hydraulic or air powered airless provide a more uniform pressure control since the paint piston moves at a constant speed except when it changes direction. In most direct drive piston pumps, the piston is crankshaft driven in which the piston will be constantly changing speed. The linear motors of hydraulic or compressed air drive pumps, are more efficient in converting engine power to material power, than crankshaft driven units. All types of paint can be painted by using airless method.
This stuff works perfectly! We'll see how long it holds up on my nicely prepped paint on my black 1996 Jeep Cherokee. I first hand washed it, then used Meguiars Clay Bar kit on it, then compounded it using Meguiars Ultimate Compound, then polished it using Meguiars polish, then used wax and grease remover to remove any oily residue from the previous steps, then applied the Mother's CMX using a microfiber foam hand applicator to spread one spray at a time evenly across the paint... Let it sit for a few minutes to bond with the paint surface, then used a really soft microfiber towel that came with my clay bar kit to buff off the dried powder residue to a perfect shine!! It wiped off very easily and then let it sit to cure for 24 hours without getting wet... It looks flawless on my fresh black paint! And water falls right off of it like all the other great brand ceramic coatings!! Highly recommend it especially for the price and the big bottle... This stuff has a very strong smell to it (must be good!), and is completely white like milk inside it if you unscrew the cap and have a look at it... I'm very satisfied, this was my first time ever using a ceramic coating before and it worked exactly how they claimed and advertised in their video Ads on FACEBOOK Coating Services
Open cell spray foams are less common and have a lower resistance to heat flow than closed cell spray does. Open cell spray foaminsulation expands when it is applied, which allows it to be installed in hard to reach areas, such as small wall and ceiling cavities. Open-cell spray foam is typically cheaper than closed cell foam is, but it is more permeable and vulnerable to fire hazards.
I've used P&S BeadMaker, Meguiars Express Wax, Carnuba Wax, CMX and most recently Meguiars Hybrid Wax. To tell you the truth, if you're a gloss and slick addict, it really boils down to how well you prep your car. Wash, clay bar, compund, and polish. IPA wipe down. Anything else you put on after will highlight the shine you prepped with all the pre-work. Spray Coating
The deposition efficiency is typically low for alloy powders, and the window of process parameters and suitable powder sizes is narrow. To accelerate powders to higher velocity, finer powders (<20 micrometers) are used. It is possible to accelerate powder particles to much higher velocity using a processing gas having high speed of sound (helium instead of nitrogen). However, helium is costly and its flow rate, and thus consumption, is higher. To improve acceleration capability, nitrogen gas is heated up to about 900 °C. As a result, deposition efficiency and tensile strength of deposits increase.

I've had concerns with foam in walls with only 2-3" and the resulting air space & convective currents. spray foam for walls is not one of my recommendations to my clients. instead foam sheathing to exterior of walls caulked,taped & sealed. conventional insulation & air tight drywall approach. a better and affordable wall with no extremely long payback like spray foam in walls. Insulation Spray Coating
Manufacturers who mass-produce wood products use automated spray systems, allowing them to paint materials at a very high rate with a minimum of personnel. Automated spray systems usually incorporate a paint-saving system which recovers paint not applied to the products. Commonly, linear spray systems are for products which are lying flat on a conveyor belt and then fed into a linear spray system, where automated spray guns are stationed above. When the material is directly below the guns, the guns begin to paint the material. Materials consist of lineal parts usually less than 12 inches (30 cm) wide, such as window frames, wood moulding, baseboard, casing, trim stock, and any other material that is simple in design. These machines are commonly used to apply stain, sealer, and lacquer. They can apply water- or solvent-based coatings. In recent years ultraviolet-cured coatings have become commonplace in profile finishing, and there are machines particularly suited to this type of coating.
While intumescent coating can be used instead of an ignition barrier or thermal barrier in some cases, the coating itself is not technically either. It does prevent or slow fires, so it has been approved to be used in conjunction with spray foaminsulation as an alternate assembly. The fact that it qualifies as an alternate assembly means that it can be used instead of a thermal barrier or ignition barrier.
The problem was that the installer was doing his first spray foam job ever, and the thickness of the insulation varied from zero (visible roof deck) to about 9". Unfortunately, good average thickness doesn't cut it. The coverage needs to be uniform because a lot of heat will go through the under-insulated areas. (See my article on flat or lumpy insulation performance.) Spray Coating
Due to a wide range of nozzle shapes and sizes, the consistency of the paint can be varied. The shape of the workpiece and the desired paint consistency and pattern are important factors when choosing a nozzle. The three most common nozzles are the full cone, hollow cone, and flat stream. There are two types of air-gun spraying processes. In a manual operation method the air-gun sprayer is held by a skilled operator, about 6 to 10 inches (15–25 cm) from the object, and moved back and forth over the surface, each stroke overlapping the previous to ensure a continuous coat. In an automatic process the gun head is attached to a mounting block and delivers the stream of paint from that position. The object being painted is usually placed on rollers or a turntable to ensure overall equal coverage of all sides. Coating Services
The Rubberseal creates a coat that can efficiently reflect heat off the roofs of buildings. It is Energy Star rated, which means it’s friendly to the environment.The spread rate of this product is 60 square feet per gallon at 20 imperial mils. It dries in 2 hours but takes 72 hours to get fully cured. Check the weather forecast before you apply it. Spray Coating Services
once the foam is installed correctly, it is a inert plastic not much different than the foam cushions you sit on. there is not a health rick unless you have off ratio uncured foam that has not mixed properly. the foam is absolutely a health risk in its raw forms before it is mixed and cured. You should not be in the building without proper respirators and eye protection. The spray foam industry should be controlled and regulated by the same standards, testing and inspections that framing ,electrical and plumbing are. until that happens then you will have idiots with spray rigs ruining peoples homes and ruining the market for honest foam contractors that know how to price a job fairly and complete it correctly.

During the 1980s, a class of thermal spray processes called high velocity oxy-fuel spraying was developed. A mixture of gaseous or liquid fuel and oxygen is fed into a combustion chamber, where they are ignited and combusted continuously. The resultant hot gas at a pressure close to 1 MPa emanates through a converging–diverging nozzle and travels through a straight section. The fuels can be gases (hydrogen, methane, propane, propylene, acetylene, natural gas, etc.) or liquids (kerosene, etc.). The jet velocity at the exit of the barrel (>1000 m/s) exceeds the speed of sound. A powder feed stock is injected into the gas stream, which accelerates the powder up to 800 m/s. The stream of hot gas and powder is directed towards the surface to be coated. The powder partially melts in the stream, and deposits upon the substrate. The resulting coating has low porosity and high bond strength. Spray Coating
