Often when people restain timber, the old Stain is either sanded away, is already flaking off, or can be restained over. While you can restain a deck over an existing stain without sanding or removing the existing peeling product, this isn't always recommended and can leave your deck looking a little worse for wear.
The other consequence of not sanding properly will be that the board will only be surface stained. It's either the stain won't dry properly or will flake off in a few weeks. It would be sad to see all that hard work go to waste.
Yes, you can stain wood that has already been stained. Sand the surface lightly to remove the top layer of the old stain, then apply the new stain. Proper preparation ensures a good finish. For more tips, see my Quora Profile.
Poor Paint Adhesion: Without sanding, paint may not adhere properly to the surface, leading to peeling and flaking over time. Visible Imperfections: Any existing damages or rough spots on the deck will be more visible if the surface is not sanded smooth.

Stains are best if your decking is a couple of years old and the colour is fading. Paint is best for older decking that needs a TLC and has the added bonus of an injection of healthy colour. And finally, oil is best if your decking is greying and needs nourishing.
You can stain an old weathered deck with proper preparation and suitable materials. Start by cleaning and sanding the deck, then make necessary repairs, such as replacing damaged boards.
Use a belt sander or orbital sander to remove any old gloss and smooth out any rough areas on decking boards. Move the sander along the direction of the wood grain. You may need to use a sanding sponge on the railings or balustrades. Lower grit numbers are more aggressive and will remove material faster.

Many people don't realize that early spring and summer are not the best time to apply stain to a deck. Wood absorbs humidity and accepts new treatments best when it's dry, so staining too early in the spring may lead to peeling or cracking.
When we re-stain decks, we do a thorough pressure wash first. Clean all the dirt and such off, and spray off anything chipping/flaking. Let it dry out, then re-stain. If you come across anything chipping/flaking, just scrape it off after it dries.
Efficiency: Power washing is quick and efficient, making it ideal for cleaning large decks. Deep Cleaning: It can effectively remove dirt, grime, mildew, and old finishes from the surface. Minimal Physical Labor: Power washing reduces the physical effort required compared to sanding.
Two Coats Recommended: Most manufacturers suggest applying two coats for optimal protection and appearance. Drying Time Matters: Wait at least 4 hours between coats and 24 hours before using the deck. Avoid Over-Application: Too much stain can lead to poor adhesion, peeling, and uneven color.

Do I need to sand the deck before staining? The answer to this is “it depends.” You won't hurt the deck by applying a light sanding. It really depends on the age of the decking and it's condition. Sanding is more for the feel of the deck than to prepare it to accept a new stain.
The best way to apply new deck stain without sanding is to clean the deck, strip the old deck stain, and apply a wood brightener. A final rinse should be done on the deck before applying the new stain. This is typically more effective, less time consuming, and requires less effort than sanding a deck.

Water-based stains need to be stripped off before you apply a new finish, while oil-based stains can be recoated after you use a deck cleaner. To test the stain: Apply a small amount of deck stripper to a small area on your deck. Let it sit for about 15 minutes, then wipe it off with a cleaning rag.

Natural Oils:
“These stains last longer and are more durable than unsealed water-based stains because there is no film on the wood to chip or fail,” according to the Green Home Guide, Tung oil is the optimal penetrating oil because it can penetrate, harden and still remain somewhat flexible.
Consider Spraying Your Stain
In fact, starting your staining process via spraying is often the way to go, as long as you implement the proper technique. Spraying your waterproof deck stain from the get-go allows you to cover even more area than rolling does and also reach those tighter spaces.
A high-quality natural bristle brush with soft but firm bristles is recommended for applying stain to a deck. Using the right brush and following the manufacturer's instructions is essential to avoid drips and streaks.
Darker color decks tend to show a lot less wear and tear, and can be much easier to clean. Anything that's a lighter color, such as very light brown or light gray, is going to show dirt more and will need cleaned more often.
