IMPORTANT: ProFlex primer is required for any RV roof where someone has put a 3rd party coating/sealant over the original roof. The primer will ensure a suitable surface for the Liquid Roof. Also owners of Fleetwood units need to apply the primer due to Fleetwood’s Alpha roof membranes. Fleetwood was popular for Alpha membranes. If you are unsure of what is on your roof we highly suggest applying the primer. When using the ProFlex primer only mix half of each part. For the gallon set part A and part B is enough for 200 sq. ft. Note when applying the Liquid RV Roof be sure the primer is still tacky. Do not permit the primer to fully cure as this will result in you needing to sand the primer to allow for adhesion of the Liquid Roof. The primer should be tacky to the point of being able to walk on it without picking up any of the material on the bottom of your feet. The manufacturer offers a warranty when liquid roof is used in conjunction with ProFlex primer.
Installing spray foam is easy to do and can dramatically improve a building or home’s energy efficiency and thermal resistance. Our closed cell foam is so efficient just 3 inches of foam appled inside of wall cavities provides an insulation value of over R18!. Our products are specially formulated for both new construction and existing homes and buildings.
The insulation at eaves level will leave your loft area comfortable for use and free from condensation. By installing the insulation at rafter level, it keeps the loft void warmer and prevents condensation build-up, which can otherwise occur when increasing insulation at ceiling level. The warmer, drier, cleaner roof space eliminates the risk of pipes and tanks freezing. http://www.youtube.com/watch?feature=youtube.be&v=ggLAUsiuI_o

Rust-Oleum® 780 Elastomeric Roof Coating provides a high initial reflectivity value of 85%, energy efficiency, long term durability and excellent resistance to weathering and dirt pick-up. This elastomeric roof coating is formulated to meet and/or exceed the standards established in ASTM D 6083. Rust-Oleum 780 Elastomeric Roof Coating waterproofs and weatherproofs metal, weathered single ply membranes as well as smooth surface asphalt built-up and modified bitumen roofing substrates. http://www.youtube.com/v/ggLAUsiuI_o&feature=youtube_gdata


The end of the gun needs to be lubricated before the first tip is installed, and again before the tanks are stored after use. Many pros prefer to lube the tip of the gun every time they install a new tip. Kits will come with some lubricant (petroleum jelly). Always follow the manufacturer’s instructions on operation, tip changes, storage and disposal.
Silicone coatings are typically produced by adding a catalyst and solvents to a silicone base. Because the silicone is a natural material, these coatings are bio-degradable. They can be applied to a roofing system using many different techniques, including spraying or rolling. Silicone coatings are available in many colors, including reflective white and translucent.
There are several types of reflective roof coatings that impart varied reflectance rates/ values. Typically, the reflective coatings are what are commonly referred to as white coatings and there are also aluminum coatings typically used with asphalt. Highly reflective white roof coatings are typically comprised of acrylics, urethanes, silicones, SBS, SEBS, and other types. https://youtube.com/v/ggLAUsiuI_o?version=3

Spray foam is a chemical product created by two materials, isocyanate and polyol resin, which react when mixed with each other and expand up to 30-60 times its liquid volume after it is sprayed in place. This expansion makes it useful as a specialty packing material which forms to the shape of the product being packaged and produces a high thermal insulating value with virtually no air infiltration.
In the case you have above the installer wasn't reading his foam. They must be trained to do that as they spray. Temps and conditions are constantly changing thru out the day. Either he wasn't properly trained or if he was,he wasn't doing his job! This is a serious problem with people jumping in to the foam business. A lot of homeowners and builders are looking the best price and end up with someone who doesn't know what they are doing. Hope this info helps. Foam insulation is a great product. It just has to be done right by someone who knows what they are doing.

Acrylic coatings are typically applied in two coats, with the second running perpendicular to the first. 1 gallon per 100 square feet is a good estimate for these coatings, as they do not need to be applied nearly as thick as many other coatings. These coatings can be sprayed or roll-applied. Acrylic coatings generally require a re-coat within 2-3 years of application.

Solvent-based polyurethane coatings have excellent adhesion and when used as a base coat over asphalt, EPDM, TPO or PVC, it eliminates the need for a primer. The resulting savings on labor and material more than offsets the higher cost of the product. When top coated with silicone, it gives you the best of both worlds. It's also an excellent gutter and RV coating.
Foam is very sticky; you'll need to wear disposable coveralls with a hood, and gloves, a face mask, and eye protection. It takes some practice to spray foam evenly and, because it expands so dramatically, to control its depth; 2 inches is all you need to seal the joist cavities. You need a clear area so that you can work without interruption; any pause longer than 30 seconds will clog the nozzle and require putting on a new one. It's also critical that the air temperature stays between 75 and 85 degrees.
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. http://y2u.be/ggLAUsiuI_o
