Deck Protection

Many people have the idea that "treated lumber" commonly used for deck construction protects the wood from the elements. But the treatment protects the wood from insects and mold but not from the weather.

Wood's main enemy is sunlight. Ultraviolet radiation slowly deteriorates wood. But there are various coatings that can keep decks in top shape: -Transparent coatings are common and allow the natural wood to show. They should be renewed yearly. -Semi-transparent and pigmented coatings offer a little more protection and give some color to the deck. They should be renewed every two or three years. -Painting offers good protection but shows wear faster than other coatings. And, finally, beware of manufacturer claims--they assume ideal conditions. Be sure the product you choose blocks ultraviolet radiation.
