It is not always necessary to remove old stain before restaining a deck. If the previous stain is in good condition and is compatible with the new stain, you may be able to apply a new coat after thorough cleaning. However, if the old stain is in bad condition, flaking, or peeling, it is best to remove it completely to ensure an even surface and proper adhesion for the new coat. Staining over a damaged layer can lead to an uneven finish and poor penetration. For best results, test a small area first and consult the stain manufacturer's guidelines.

Painted decks typically require a new coat about once every ten years. In between new coats, it's best to maintain your deck by regularly removing debris, washing it down with non-abrasive cleaners, and staying ahead of structural issues, such as loose boards and rotting wood. In some cases, painting a small section of your deck affected by damage or the sun can lower your costs and workload.

An exterior paint job typically lasts between 5 and 10 years, though this can range from 3 to 17 years depending on several factors. The longevity is influenced by the quality of the paint and primer, the quality of the application, the local climate, and the type of surface being painted. For example, paint on wood siding may need to be redone every 3 to 7 years, while painted brick can last up to 17 years. Aluminum siding often needs repainting every 5 years.

Staining or sealing a cedar deck or fence is highly recommended to extend its lifespan and protect it from the elements. While cedar is naturally resistant to mold and mildew, it is not impervious to damage from moisture, sun exposure, splintering, fading, and rot over time. Applying a protective finish creates a shield that preserves the wood's strength and appearance, potentially extending its life by five to 10 years.

When choosing a finish, it's helpful to understand the difference between a sealer and a stain. A sealer sits on top of the wood, whereas a combination stain and sealer soaks into the top layer. Because it penetrates the wood, a stain generally offers better protection against UV damage and rot and lasts significantly longer. For the best results that also preserve the wood's natural color, consider using a near-translucent stain.

To maintain protection, plan on reapplying the stain or sealer every two to three years, either as a DIY project or by hiring a professional.
