Many people are under the impression that staining your wood is only for cosmetic benefits. While a color tint will help you decide which stain you prefer, the real reason to apply stain is PROTECTION.  While wood in general is a very hearty material, without any protective stain wood is exposed to moisture, nature’s elements and air-borne particles continually.  Untreated wood results in graying, splitting and splintering.  Even dry rot will occur at a faster rate for untreated wood.

To really understand why wood needs protection, one must understand the basics of wood and even more so one needs to understand the basic cellular construction of wood.

All wood that has been cut is left with a surface that is made up of open cells. These open cells form catch basins where microscopic air-borne particles can come to rest.  Air-borne particles such as spora from trees and bushes, emissions from air pollution and dirt are all particles that can get into those catch basins and become one with the wood.  Once the air-borne particles become one with the wood there is a negative reaction which is a gray color, resulting in tired looking wood.  When you stain with an oil base stain such as Preserva Wood the stain dries within the wood and unites with all particles on and in the wood. When wood is not cleaned before staining the air-borne particles become part of the wood. For this reason it is so important to clean wood before every application of any stain.   Did you know that even brand new wood needs to be cleaned?  Some may be surprised to hear this, this is because moisture, nature’s elements and microscopic air-borne particles are everywhere and unavoidable.

When you apply stain to wood, the process of filling up the catch basins begins and this results in fewer places for the air-borne particles to hide. Each time you apply stain to your wood, the cells get coated and this results in less open space for air-borne particles to hide.

Wood should be cleaned semi-annually, once in the spring and then again in the fall. When it’s time to re-stain your wood it’s important to note that Preserva Wood stain will cover more square footage on the second application.  This is because the cells have already absorbed stain during first application, this stain remains inside the wood even after being cleaned.

After first application of Preserva Wood, all protective ingredients remain permanently as part of the wood. Your wood is protected and ready to face nature’s elements & air-borne particles.

So should you stain your wood? In short, YES!  Wood needs protection and applying stain will prolong the life of your wood.
