Alpha Particles. Alpha particles are a type of radiation that do not travel very far, do not pass through anything very thick, and can generally be absorbed or stopped by an inch or less (1-2 centimeters) of air or a thin piece of tissue.
People stain or paint their decks in order to protect and preserve the wood. Outdoor decks take a lot of abuse from weather and the natural elements and require a high quality paint or stain to protect the wood. Decks require regular maintenance and are usually painted or stained every three to four years.Staining a deck emphasizes the natural grain of the wood.utdoor decks take a lot of abuse from weather and the natural elements and require a high quality paint or stain to protect the wood.

As a general rule, the air temperature for good painting conditions ranges from 55 degrees to 85 degrees. Unfortunately, when applying paint or stain it is the surface temperature, not the air temperature that is important. Air temperature and surface temperature can be miles apart.If a wood deck or wall is in direct sunlight it may well be 30 to 50 degrees hotter than the air temperature.One sunny day in May the air temperature on our test deck was 55 degrees, but the surface temperature of the wood was over 95 degrees. In other words, it was already too hot to stain successfully.pply stain only at the proper temperature. For most stains, 70 degrees Fahrenheit is the optimum, with the safety range from 50 to 90 degrees Fahrenheit. Stains do vary, so check the label first.
