To maintain the useful life design of your polyon greenhouse Polyethylene film, the guidelines below should be followed.

1. If high winds and impact are a frequent problem, two layers of film, inflated with air, should be used. Outside air is recommended for inflating the film due to its low moisture content at low temperatures and its low concentration of chemicals. It is recommended that the air pressure between layers correspond to 0.25"-0.35" of water measured on a manometer.
   Air inflation should be directed at a 45 degree angle to the film. Do not direct perpendicular or near perpendicular. The air should not directly impinge on the film surface. A deflector or diffuser should be used.
   
2. Locking channels should be used to secure the film. The bubble should be maintained as airtight as possible in order to keep the proper inflation between film layers.
   Wooden slats are not recommended to lock down film. However, if slats are used, they need to be clean, smooth, and coated with a heavily pigmented white, flat latex-based paint. At time of installation, film should be wrapped at least one turn around the slat before nailing to the frame.
   
3. Any nicks, scratches, or torn areas on the film should be patched immediately. A tape made from greenhouse film containing a UV stabilizer adhesive will achieve best results.
   
4. All metal and wood surfaces, including rafters, in contact with the film should be painted with a heavily pigmented white, flat latex-based paint to reduce heat stress.
   
   Treated wood which often contains organic solvents that can damage the film, should also be painted with a heavily pigmented white, flat latex-based paint. Paint should be dried completely before the film is installed.
   
5. Greenhouses using PVC pipe in contact with Polyon film require special preparation prior to installation of the film over the structure. Certain types of PVC pipe contain high loadings of highly reflectice calcium carbonate. These highly reflective surfaces accelerate conversion of the Ultra-Violet Inhibitors in the film, accelerating degradation of the film in contact with the pipe.
   Pipe surfaces in contact with the film should be painted with a heavy coating of highly pigmented white, flat latex-based paint. Pipe surfaces may require light sanding to obtain satisfactory adherence of the paint to pipe surface. Sufficient time should be allowed for the paint to thoroughly dry and cure. The paint, by reducing reflection, will absorb a considerable amount of the Ultra-Violet rays.
   These precautions apply to all polyethylene films and should be followed when using all Polyon films.
   
6. After the film is installed, a heavily pigmented white, flat latex-based paint should be applied to the area over and around the locking channel and an area on the film approximately six inches above the lock.
   
7. If shading is desired, use only those compounds manufactured for the express purpose of shading greenhouse films.
   
8. If a shade cloth is used, either under or over the film, it should not be in direct contact with the film.
   The movement of a shade cloth against the film will tend to cause abrasions as well as create heat buildup.
   
9. Organic solvents or petroleum-based products should not be put in contact with or in close proximity to the film
   
10. Fungicides, pesticides or herbicides should never be put in contact with or in close proximity to the film.
    
11. Do not leave soap or detergent of any kind on the film. Immediately after washing the film with a soap or detergent, rinse thoroughly and carefully with water.
    
12. Maintain at least a 3% slope for films with an anti-condensate additive in order to allow moisture buildup to adequately run off.
    
13. Failure to properly prepare the structure prior to installation will void our warranty.
