I used polyurethane for the fist time today and I’am delighted with the results. one coat was more than enough to give a smooth glass like finish , I used it on a handrail and will post pictures of it next week

Polyurethane is good stuff. There are many different kinds available. I’m not sure I’ve seen any of them that recommend using only one coat. Even if a single coat looks good, you should check the label and use the minimum number of coats suggested. Multiple coats will last a lot longer and keep your project looking good for many years.

yep with good surface prep 1 coat will have it looking and feeling good but poly is made to soak in so for it you want 4 coats minimum, but about 6 or 7 coats would be better. so you can get good protection from the wood!

You should also lightly sand with 400 grit paper or 0000 steel wool between coats. I usually use a gloss finish. I sand or buff until it is no longer glossy. After sanding, wipe it down with mineral spirits to remove the dust and residue. This creates a good bond for the different layers of finish. If using a water based poly, do NOT use steel wool. Any fragments left over will rust.

The gloss poly is the most durable. If you want a less glossy finish, knock it down with steel wool and then wax.
