Deck Sanding Tips to Get the Perfect Repaint

A fresh coat of paint or stain can completely transform your deck—but only if the surface is properly prepped. One of the most important steps is sanding. If you’re searching for the best deck sanding tips, you’re in the right place. Smoothing the surface helps paint adhere better and last longer, even in high-traffic or coastal areas like Long Island.

At Big Expert Painting LLC, we help homeowners prep and repaint decks the right way, from Amityville to Babylon. Whether you’re doing it yourself or planning to hire a pro, this guide will help you get the most out of your next repaint.

Why Deck Sanding Matters Before Painting

Even if your deck looks clean, uneven wood or old peeling paint can prevent new layers from sticking. That’s why sanding is essential. It removes rough spots, opens the wood grain, and allows paint or stain to penetrate evenly.

This step is especially important after you power wash the deck before painting. Power washing can raise the wood fibers slightly, creating a fuzzy texture. A light sanding smooths everything back down and helps your topcoat go on clean.

Sanding isn’t about removing every bit of old paint—it’s about creating a stable, clean surface. For older decks, it’s also a good chance to spot loose nails or damaged boards before painting begins.

How to Prep a Deck for Painting

Proper prep goes beyond sanding. First, clear the deck completely—furniture, plants, and any debris should be removed. Sweep and rinse to eliminate loose dirt, then apply a deck cleaner if you see mildew or stains.

Once dry, power washing helps clean deep into the wood grain, but be sure to let the deck dry fully before sanding. Start with medium-grit sandpaper (like 60–80 grit) for rough areas, then switch to finer grit (100–120) for a smoother finish.

Be sure to sand railings and stairs too, as these areas get lots of contact and wear. This full approach makes your deck safer and more paint-ready. For full-service prep, check out our

Choosing the Best Paint for Decks

Once sanding is complete, you’ll need a paint that can handle outdoor exposure and foot traffic. The best paint for decks is typically an acrylic-based formula or a solid color stain. These coatings provide durability and resist fading from UV rays.

Paints designed for decks are often mold- and mildew-resistant, great for Long Island homes where moisture and shade are common. If you’re unsure what type of paint suits your deck material, we can guide you through your options during your repainting project.

For a full makeover, you might also want to coordinate your deck color with your home’s trim or siding. Our

Deck Color Ideas for 2025

This year’s deck color ideas for 2025 focus on soft, natural hues and coastal-inspired tones. Think warm grays, rich browns, and ocean blues. These colors pair well with both modern and classic home styles.

Neutral shades like “driftwood” and “stone gray” are especially popular, offering a clean and timeless look. If you want something bold, consider navy or forest green as accent colors for railings or stairs.

A fresh color doesn’t just look great—it also hides wear and extends your deck’s life. Just make sure your surface is properly sanded and sealed before applying new color.

When to Paint Your Deck in Long Island

The best time to paint your deck is during dry, mild weather. In Long Island, spring and early fall offer the most reliable conditions. Avoid painting in extreme heat or humid days, as paint may dry too fast or too slow, leading to bubbling or peeling.

Be sure your deck is fully dry after sanding or washing. Painting over damp wood traps moisture and leads to early failure. With the right prep, including sanding, your new paint job will last for years.

Routine deck maintenance in Amityville and surrounding areas includes periodic cleaning, sanding, and sealing, keeping your investment in great shape year after year.
