Think your wood is protected? It has color, it’s protected right! This semi transparent stain was applied over 7 years ago, the color may be there but the protection is not.
This project located Rancho Mirage has been exposed to the harsh elements for over 2-3 years. Some of the wood was actually falling off. Stained/sealed exterior wood in the Palm Springs area should be recoated every 2-3 years, depending on the exposure to the sun. In some cases it needs to be sealed yearly, like the natural wood garage doors or front doors. Doors get beaten up far more as it is exposed to the scorching heat for longer periods. Here is a picture of 2 boards that received a freash coat of semi transparent stain. The color applied was the original color whem 1st applied. You can see the drastic difference.
Painted wood is not as critical because paint has a harder shell with higher UV protection. If the wood has been properly prepared, primed and received the right amount of mills, with the qualified product. You can get 7-8 years of protection out of it. However I would recommend at least every 5-6 years. The longer unsealed wood is exposed the more preparation is involved. The less it is exposed, the less preparation is needed. Take a moment and examine your wood and get protected before it turns into costly repairs.
