Yes, staining or sealing a cedar deck or fence is highly recommended to extend its lifespan, typically by five to 10 years. While cedar is naturally resistant to mold and mildew, it can still fall victim to moisture, sun exposure, and rot over time. Applying a treatment creates a protective shield that helps prevent splintering, fading, and decay, preserving the wood's strength and appearance. A combination stain and sealer often provides the best protection, as it soaks into the wood grain rather than just sitting on top. This offers superior defense against UV damage and rot and lasts longer than a sealer alone. To maintain the wood's natural look, consider using a near-translucent stain. You should plan to reapply the stain or sealer every two to three years.

You can refresh a painted deck by either giving it a thorough cleaning or refinishing the deck altogether. Chipped or faded paint, as well as extensive damage, often calls for a new finish. To do this, remove the original coat of paint with a sander and add either a new coat of paint or a stain to protect the wood below.

Yes, you can and should paint or stain pressure-treated wood to help prevent the boards from cracking. However, you must wait for the wood to dry out completely before applying any finish. Freshly treated wood can take weeks or even months to dry; a common recommendation is to wait three to six months. To check if the wood is ready, perform a simple water test: drip some water onto the surface. If the water beads up, the wood is still too wet and needs more time to dry. If the wood absorbs the water, it is dry enough to be painted or stained. You can proceed with building your deck or fence while the wood is still wet, but you will need to wait to apply the paint or stain.

Always sand a deck before repainting so the wood is smooth and ready for paint. While you do not need to fully remove paint before repainting, sanding helps remove any areas with weather and sun damage. Sanding also helps remove chipped or flaking paint and opens the wood pores to improve paint adhesion.
