Q. I’m presently using latex paint. Why should I switch to Premium Greenhouse Shading?

A. Premium Greenhouse Shading (PGS) is more concentrated that most latex paints. Latex paint can usually only be diluted at a rate of 3:1. PGS is typically diluted at a rate of 8:1. Better mileage! Latex paint may also flake off, clog up spray nozzles, cause abrasion and wear to spray equipment, and deteriorate plastic. Latex paint may also yellow with age because of cheaper pigments and ingredients. PGS is also available in three formulations to allow you to choose the amount of adhesion that suits your specific growing situation.

Q. Is PGS as good as other leading shading compounds on the market?

A. Yes! Most growers that have compared PGS to other brands prefer PGS. In many cases, PGS is

less expensive than other brands and PGS is manufactured in California and always available when you need it.

Q. Do I need to keep PGS agitated?

A. No. Once mixed, PGS will stay in suspension during normal applications.

Q. Many shading compounds tear up my spray equipment. What about PGS?

A. We use only ultra-fine pigments and materials to insure that PGS will be very low in abrasion.

Q. What type of coverage can I expect from PGS?

A. At an 8 to 1 dilution, you should get about 10,000 sq. ft. of coverage per 5 gallon bucket. Coverage will vary depending on method of application and the surface you are applying it to.

Q. What is the best way to apply PGS?

A. Many growers prefer to apply PGS with an airless paint sprayer with an extension on the spray gun. Airless sprayers atomize the shading at about 3000 p.s.i. This allows for a more uniform application. These sprayers are available for rent at most rental yards. Other growers obtain satisfactory results by using standard pesticide sprayers. Smaller greenhouses may also be shaded using a paint roller or pump up type sprayer.

Q. How does PGS stick to new poly?

A. Application of any shading compound to new poly can sometimes be a problem. This is due to the “oily” coating on the poly that prevents sticking while the poly is rolled up. Usually this coating will evaporate after being exposed to the sun for about a week. Growers that need to shade immediately will sometimes add a small amount of spreader-sticker to PGS, or wash the poly with detergent and water before shading application.

Q. What is the shelf life of PGS? Will it turn rancid like some other brands I’ve tried?

A. If kept above freezing, PGS should store well for several shading seasons. It will not turn rancid.
