Wood stains

Wood decking has a warmth that synthetic decks lack. But you pay a price in maintenance: Wind, rain, summer sun, and winter snow can take a noticeable toll on its finish in only a few months. Some deck treatments can lighten your workload by lasting longer before they have to be reapplied.

To see how well each deck treatment we tested protects, Consumer Reports applies various stains to wood panels at its Yonkers, N.Y., headquarters and leaves them exposed to whatever Mother Nature dishes out. The best we've tested still remained close to their original color after three years, picked up only a little dirt and mildew, and effectively protected the wood from cracking. The worst looked ratty and provided little protection after just one year.

While the longest-lasting products were often the most expensive up front, their longer life should save you money over time. Don't buy strictly by brand; different products from the same manufacturer often performed differently. What's more, a product that worked well for you last time may not do as well this time, as manufacturers keep reformulating to address cost and performance, and to comply with government regulations.
