Is water based or oil based sealer better for wood?
If you are going for a gray-stained, white stained or a white-washed hardwood floor, you must use a water-based poly, because an oil-based poly will make those floors look yellow. Over time, they will continue to look more and more yellowish.
Oil-based sealers are better for pine, cedar, oak, ash, and other types of wood that have a high absorption rate because oil-based sealers are not as easy for the wood to absorb as water-based products. However, an oil-based wood sealer typically has better UV resistance and tends to have a more even finish.
Things You Should Know. Water-based stains preserve the look, feel, and color of wood, but they're harder to apply and maintain. Oil-based stains hold up better in crazy weather, they're more durable, and they're easier to work with.
Water-based polyurethane scratches and dents easily. Oil-based polyurethane coatings provide excellent abrasion and scratch resistance. This makes them a good choice for wood floors or for any application such as cabinets, railings, or countertops where durability is critical.
Oil-based sealers have long been favored for their numerous advantages, particularly their exceptional durability. These sealers can effectively safeguard your driveway for up to four years, depending on the specific product and prevailing environmental conditions.

Liquid sealants are one of the most common ways to waterproof wood. These sealants are applied directly to the surface of the wood and form an impermeable barrier against water penetration. It is important to apply several coats of sealant to ensure a thorough application.
Water-based products do not last forever, even when unopened. General Finishes products are best used within 1 year of the manufacture date listed on the bottom of the can. The life of the product may be extended to 2-3 years with proper care and storage.
Compared to water molecules, oil molecules are much smaller in size, enabling them to penetrate the board more deeply with an added layer of moisture beneath its surface. As a result, wood stains that contain oil have been proven to be longer-lasting and possess higher durability than those consisting of only water.
water based: can last around 10 years when high quality product is applied by professionals, inexpensive lower quality product may last only 5-6 years. Water based is harder which offers greater dent resistance. oil based: generally lasts around 10 years. Oil based is softer which can offer greater scratch resistance.
What is the downside of oil based polyurethane?
Cons of Oil-Based Polyurethane
Longer dry times. Dents easier due to it softer finish. The odor is unbearable (respirator use is recommended). The floor darkens over time.
The water in water based polyurethane tends to “react with the grain” more, so you often need to apply more coats to achieve a smooth, finish.

An oil based polyurethane will continue to amber and darken over time, while water based poly will remain clear for the lifetime of the hardwood floor. This color difference is less noticeable over a stained hardwood floor, but an oil based poly will still exhibit an amber hue that will continue to darken over time.
Water-Based Deck Stains
The new kid on the block, water-based stains have become an extremely popular sealer option for wood decks. For one, it dries quickly – with a water-based stain you only wait two or three hours maximum, vs. the 48 hours an oil-based stain takes to dry.
QUESTION: Can oil and water based products be used over each other? ANSWER: Yes! but the underlying finish has to be absolutely dry.
Most oil-based stains must dry for at least 12 hours before they are exposed to any moisture/rain; however, Ready Seal, if properly applied to prepped and dried wood, can get wet within a couple of hours, and it won't wash away. Oil-based stains will generally take 24-72 hours to fully cure.
It is fundamental to apply three coats of sealer to wood surfaces because the initial coat will simply penetrate inside. The second coat binds with the first coat, forming a seal. The final coat, on the other hand, provides protection from scratch, heat and water.

What is the best treatment for outdoor wood?

In conclusion, while wood sealers do a remarkable job of enhancing wood's resistance to moisture, they don't achieve complete waterproofing. Nevertheless, they are an indispensable tool in preserving the beauty and integrity of your wooden projects, ensuring they stand the test of time.
While water-based sealers offer environmental benefits and a quick curing time, their durability falls short in comparison to oil-based sealers. The surface protection they provide may not stand the test of time, necessitating more frequent reapplications.
Water-based sealers have a lower level of VOC (volatile organic compounds) content than a typical solvent-based sealer. This means it is less harmful to the person using the product, as well as the environment.

Oil-based stains, on the other hand, protect by penetrating deep down into the wood's pores and sealing water out. Their oil content, however, makes them less resistant to other moisture-related problem causers, like mold and mildew, which feed on some materials found therein.
Water based poly dries much faster, and several coats (up to 4) can be applied in one day. Water based poly can be walked on with socks in about 4-6 hours after last coat has been applied, while oil based poly must dry for at least 24 hours before walking on it with socks.
Water-Based Wood Stain
Water-based stains are typically less toxic and easier to clean up than oil-based stains. They penetrate the wood surface to colour the wood without raising the grain, and they don't require a topcoat. Water-based stains can be applied to both indoor and outdoor projects.
A water based coat dries much faster then the oil base. A few coats can be applied and dried all within several hours.

A polyurethane finish is applied to the surface of the wood, but doesn't penetrate it.
Water-based Polyurethane Finishes
Most water-based finishes dry clear and do not change color over time. The “yellowing” of the floor's color often seen with oil-based polyurethanes won't happen with water-based.
Oil-based polyurethane is more durable than his water-based alternative since it contains a significant amount of Volatile Organic Compounds (VOCs). Those chemicals make the finish tougher and allow it to last longer.
Water-based polyurethane can take anywhere from 3 to 21 days to cure. It's touchable after 24 hours. You can put on some furniture after 2 days. And officially cured on the 20th day.

Give it a few more days to see if it improves. Another possibility is that the stain was old or came from a bad batch. In either case, if the tackiness doesn't go away, wipe the wood down with mineral spirits or naphtha to remove most of the stain, let it dry thoroughly, then try again using a fresh can of stain.
Average dry times are as follows: Hard wax oils: 4-24 hours. Water-based finishes: 4-8 house. Oil-modified polyurethane: 12-24 hours.
When the moisture content of the wood is below about 25%, you can use the sealer, but if you haven't got a moisture meter that's not going to help much. Damp wood can be felt with the skin as a sensory organ; this is not widely known.
Stains also have water repelling qualities, as the stain does not allow water droplets to penetrate the wood. Applying stains is a bit trickier than sealers, but it can last longer and look more professional.

I often use Sealcoat shellac as a sealer, however. But both can be used to give a more uniform staining job on blotch prone woods like maple, pine, etc. In any case, you allow the sealer to completely dry before applying the stain, and often it's best to lightly sand the wood with 320 or 400 grit before staining.
Sealers are different from oils. They don't “feed” the wood with more oil, but instead seal oils in the existing wood.
