Staining a deck with a rag is typically a better option than using a brush, as it helps the stain penetrate deeper into the wood. However, both brushes and rags are best reserved for detailed work because using these tools on an entire deck can require tediously crawling around on your hands and knees. A pad applicator, sprayer, or roller are preferred alternatives to applying stain over the majority of a deck. Use a rag for railings and other detailed work, and let the wood soak up as much of the stain as possible before wiping away drips or pools.

Yes, it is important to wash your deck before painting to ensure the paint applies well and adheres properly. While you don't have to use a pressure washer, it is one of the most efficient cleaning methods. Pressure washing can quickly remove dirt, wood fibers, and flaked paint, getting deeper into the wood than manual scrubbing. You can also clean the deck with a stiff broom and a cleaning solution. Regardless of the method, a clean surface is essential for good paint adhesion. Make sure the deck is completely dry before applying any paint.

Exterior paints contain more volatile organic compounds, or VOCs, making them dangerous when used indoors. Without the free ventilation of the great outdoors, it can take longer for the fumes to dissipate than interior paint. While you may notice the smell lessening more quickly, you should be wary of paint fumes inside for 48 to 72 hours after it dries.

Opt for an interior wood stain that is rated for your type of wood. Consider your personal style preferences as well as the overall use of the room when choosing a color. Remember, the color you see at the store may look different on your actual floors once applied. This is why if you have the chance, it’s helpful to test a few options on a scrap piece of wood in the room first. Once you narrow it down, you can test a small patch on an inconspicuous area in the room to see it on the actual floors.
