Nothing beats the warmth, character and durability of cedar trim on the outside of a home. However, many shy away from using it because it has a reputation of being a high maintenance product. best deck paint for old wood
Like anything, it’s important to understand the nature of the product you are finishing to get the best results from your paint or stain. Doing so will give you many years of lasting, low-maintenance wood siding.
Red cedar is one of the most effective wood species for exterior siding. It retains a variety of finishes well, excretes no pitch or resin, is naturally resistant to decay, and its low density qualities prevent excess shrinkage or swelling.
Some general rules when choosing an exterior finish include:
Use only corrosion-resistant, hot-dipped galvanized, aluminum or stainless steel nails to prevent stains.
Never leave cedar to weather without a protective coating as some manufacturers recommend. Even a few weeks of weathering can decrease cedar’s ability to hold a finish and may cause blistering, or cracking.
To obtain the naturally weathered look, use artificial stains designed for that purpose. These commercial bleaching stains are water-repellent and contain pigments to give that gray shading of weathered cedar.
Some prefer the look of newly milled cedar which also can be obtained by using finishes that contain chemicals that block out the sun’s ultraviolet rays.
Always choose a finish containing ultraviolet blockers and mildewcide to protect the wood.
The more solids your finish contains, the less maintenance it will require. In otherwords, painted wood may last up to 10 years where a solid color stain about 3 to 5 years. Semi-transparent stains last 1 to 3 years and water-repellent preservatives and oil about 1 to 2 years. These numbers are all slightly increased when applied to textured cedar as opposed to planned or smooth cedar planks.
