How to Stain an Old Deck: The Ultimate Guide

How to stain an old deck including the materials needed, stain options, stain application, after stain care, and best practices to stain an old deck.

Decks are great places to relax and get some fresh air. However, it might not be so relaxing if your deck is ancient. You can wear out older decks and splintery. They can also be prone to rot and dry rot. Whether your deck is old or new, it can benefit from being stained. It can help protect your deck from the elements and make it more comfortable to walk on.

How to stain an old deck

Staining an old deck can be tricky. You don’t want to add too much weight to your deck, which could cause it to collapse. However, you want your patio to be protected from the sun, rain, and other elements. You also want your deck to be comfortable to walk on. You can accomplish both of these things by properly staining your old deck.

Tools you will need

Even a small deck requires a lot of water to keep it wet enough for staining. A garden hose is not nearly powerful enough, so you must hook up a powerful external sprayer.

Tools to stain your deck

Dry brushing techniques work best when the surface is still wet but can also work effectively when the wood is dry. So you can get by with just a garden hose and a deck scrub brush.

However, if you want to use a paintbrush to apply the stain, you must keep the surface wet. And this takes more water pressure. So we recommend hooking up a powerful, external sprayer to ensure you have enough water pressure to keep the wood wet.

If you are using a semi-transparent deck stain, you can work faster because you can see where you have already stained. But if you are using a solid deck stain, you will need to use a sanding block to help move the stain around the wood.

Supplies you will need

Deck cleaners are available in various products with varying strengths, from mild deck cleaners to deck strippers. An increasing number of deck cleaners are water-based. Water-based cleaners are safe for the environment but do not have the same cleaning power as solvent-based cleaners.

What do you need to stain a deck

Solvent-based cleaners are the most potent type of deck cleaner, but they are not environmentally friendly. They can also be dangerous and cause severe skin irritation upon contact. Solvent-based cleaners are suitable for removing old paint and stains, but most do not offer the same deck cleaning options as water-based cleaners.

Solid stains are often painted or pigment-based stains mixed with a thickening agent, usually a natural gum or resin. Solid stains can be purchased as pure pigment or in pre-mixed colors. Because they are thick, solid stains can be challenging to apply, and they do not penetrate wood grain nicely. Solid stains are often messy and can be unforgiving if you make a mistake.

Solid stains

Even though they are not always the best option, solid stains are easy to find at any home improvement store. They are also a low-mess option for stained decks since they do not come in a liquid form. The best way to apply solid stains is with a paintbrush since they will not drip or run.

How to prepare the deck surface

To create an excellent, even deck stain, removing all of the old, chalky finish from your entire deck is essential. Start by scrubbing down the deck boards with a deck brush and a stiff deck cleaner. Once the panels are clean, you can use a deck brightener, deck stripper that contains sodium hydroxide, or another chemical to remove the surface wood fibers.

How to prepare the deck surface

Before you apply any deck stain, you should sand the entire surface of your wood deck. Use fine-grained sandpaper to remove the rust, then move up to medium-grade sandpaper to smooth the surface further. If you are staining a stained or varnished deck, you do not need to sand the texture. Make sure it is clean, and the cover is free of wax and oils.

You should move up to fine-grained sandpaper for a natural wood deck to give the wood a smooth surface. If you want to add a gloss, move to super fine sandpaper.

For composite decking, you can skip the sanding process. If you want a glossier finish, you can begin with a deck stain already semi-gloss and move up to a gloss deck stain.

How to stain an old deck

Even old, weathered deck boards can still be stained and made to look great. But you will need extra care with an older deck to ensure you don’t have problems.

How to stain an old deck

The first thing to do is sweep all the old wood dust and dirt off the deck boards. Then, use a deck-cleaning solution to wash the deck boards. Use a diluted oxalic acid solution or a natural deck cleaner for a natural wood finish.

After the deck boards are cleaned, you can start staining. Start with a thin, even coat of stain. Let this dry, then apply a second coat of stain. The second coat should be a little thicker, but not to let it slide in low spots or pools on the surface.

For the final coat, you can thin the stain down with a bit of water so that it is more like paint than varnish. This will give you more even coverage because you can move more quickly.

Tips for staining a deck

For a deck that is well maintained, a good, solid wood surface will take up to 5 or 6 coats of stain properly. While the wood is still wet after the first coat, it is essential to note the appearance of the stain. If the color is too dark, you must apply another coat.

Tips for staining a deck

The key is to apply thin coats. If you apply too thick a coat of stain, it will not absorb evenly, and you will end up with an uneven finish. For this reason, it is essential to wait 15 or 20 minutes between each coat.

To give your deck solid UV protection, you must apply 5 or 6 coats of stain. For a deck that you just want to give a quick touch-up, 2 or 3 coats will suffice.

deck staining tips

The color of your deck depends on the type of stain you use. There is a range of deck colors to choose from, varying from a light, natural wood tone to dark chocolate hues.

If you have an old deck that you want to give new life, staining it is a great option. You can achieve beautiful, long-lasting results with the right tools and techniques. This guide provides everything you need to know about how to stain an old deck, from choosing the right stain to preparing the surface and applying the stain. With a bit of time and effort, you can have a stunning deck that will add beauty and value to your home.
