How to tell deck stain is bad? Deck stain that has gone bad will clump, thicken, and form a film on the top layer. Bad deck stain will also give flawed results when used on a deck or fence.
The sun beating down, the rain pounding, and the snow piling high. Dirt and residue are going to settle in and build upon that flat surface. That's why it's so important to treat your deck with a good quality stain or paint. The best stains should last 3-5 years when applied correctly.
Yes, you can put a stain over an existing stain on a deck, but there are a few important considerations to keep in mind: Compatibility: Ensure that the new stain is compatible with the old one. If the existing stain is oil-based, it's best to use an oil-based stain on top.

Darkness Depends on Wood Type: One coat offers a lighter tone; two or more coats deepen the color but may obscure the grain. Test First: Always test a small section to assess how the stain interacts with your deck's wood.
Semi-Transparent Deck Stain
Semi-transparent stains are one of the most popular choices by many homeowners when staining their decks. It is water repellent and provides enough protection against the harsh heat of the sun, and at the same time, allows the beauty of the wood to show through.
Too Much Stain and Trapped Moisture
Wood can only absorb so much stain. If too much stain is applied, the excess material will linger slightly above the surface and prevent moisture from rain and dew from leaving the wood. If this moisture can't evaporate, it will remain on the surface and begin peeling away the stain.
Solid stains are nearly indistinguishable from paint. The primary visual difference is that solid stain has no sheen and does not reflect light. Solid stains provide a thick, colored film that can be made to match or coordinate with the colors of your home siding.
To tell if it is still good, start with a visual inspection. Discard finishes that have become thick, rubbery, stringy or separated, as well as those with a skunky odor or obvious mold growth. Ditto for water-based paint or finish that looks like cottage cheese.
Because you want to wait for days that aren't excessively hot or humid, the best times to apply deck stains are in the late spring and early fall, when the weather is moderately warm and dry.
Decks that have seen minimal wear and are not exposed to harsh weather conditions may not require stripping. If the wood surface is in good shape and the old stain is still intact, a light sanding and cleaning may be enough before applying a new coat of stain.
It's usually due to applicator lap marks which you can fix, but you need to leave it for at least 7 days for the coating to harden up then lightly sand the lap marks out and recoat the deck.

Before applying stain, make sure your deck has been cleaned properly. Sprinkle some water on the deck. If the droplets soak in, the wood is ready to be stained.
In some cases, you can get away with leaving the previous coat as it is, as long as you perform the other necessary preparation steps, such as sanding and power washing. If, for instance, the new stain is the same brand and color as the old stain, you might not need to go through the complete removal process.
Vinegar is acidic so, normally, it's actually used to remove stains. Issues can arise when vinegar is left to sit on decking for too long, as doing so can seep the color out of the wood. Using undiluted vinegar is especially harmful, as the stronger concentration results in even more acidity that can damage your deck.
Most opened stains can last 12+ months if stored correctly with the lid tightly sealed.
