Wet-sanding and dry-sanding each have pros and cons. Dry-sanding is less messy, so it’s a good option if you’re trying to minimize dust (for example, if you’re sanding an occupied home or working with particularly dry or dusty drywall mud). However, dry-sanding is quicker because you don’t have to keep rinsing a sponge or wait for it to dry before painting.

Satin paint is generally considered a better choice for woodwork—including trim, baseboards, cabinets, and doors—than flatter finishes like eggshell or matte. Its soft sheen enhances architectural details and stands up well to frequent cleaning and daily wear. Compared to eggshell and matte finishes, satin is more durable for high-touch areas because it is less porous and doesn't absorb dirt as easily. Matte finishes, in particular, are prone to scuffs and are harder to clean, making them less practical for surfaces like doors and cabinets.

The best way to protect a deck is to prevent damage from UV light, water, mold, mildew, insects, and abrasive cleaning methods. Sweep regularly to prevent debris that hides bugs and traps moisture that can result in mold or mildew growth. Use a deck cleaner once a year to remove algae, mold, and mildew. Avoid using pressure washers on high, as they can damage the wood. Applying a deck sealant can protect the wood from UV and water damage, and adding shade can also reduce sunlight damage.

For the longest-lasting exterior paint, consider acrylic or enamel (oil-based) paints. Acrylic paints, including acrylic latex and acrylic enamel, are known for withstanding harsh weather and sun exposure. Enamel-based paints are also one of the most durable options available. While latex paint is common, it typically has a shorter lifespan than acrylic or oil-based options. The paint's finish also affects its durability; a higher gloss finish is generally more durable. For resistance to moisture and cracking, matte and satin finishes can be effective, while a high-gloss acrylic or oil-based paint offers a combination of maximum longevity and durability.
