Why do wood tables crack?

When it's more humid, the moisture in the air is absorbed by those drinking straws or wood fibers and the wood swells. Worse yet, if the wood is joined improperly it can cause the wood to crack and split. When it's less humid, moisture is released by those drinking straws or wood fibers and the wood shrinks.

Can you oil green wood?

Well, consider a curly piece of crotch wood, or a green-turned burl. This can also be done with some oils instead of water, but I usually just use water for sanding up to 320 or 400, then dry the wood with towels, and apply oil to the surface by hand.

Will polyurethane make wood waterproof?

The answer is no, polyurethane does not make wood waterproof even if you coat all sides and ends with multiple coats… at least not for very long. Wood expands and contracts and naturally contains moisture even when kiln dried. As it moves it eventually compromises the finish and allow wetness to invade.

Does polyurethane make wood harder?

Yes, polyurethane provides a protective layer on hardwood (as well as furniture) making it harder for water to penetrate into the wood. But, it is not waterproof; rather, it's water resistant.

Do I need to seal wood before polyurethane?

NOTE: Water-based stains will need a fine sanding with 220-grit sandpaper after the stain is dry. Also, some stains are self-sealing. To seal the wood before top coating, thin your oil-based polyurethane to one part mineral spirits and two parts polyurethane (first, gently stir the contents in the can).

Should I put polyurethane over stain?

Whether you put a polyurethane finish on wood that has been stained is entirely up to you, and so I cannot in good faith say that you are "supposed" to do so. But you certainly can do so, as long as you ensure that the stain finish is dry before applying the polyurethane topcoat.
