Sanding before sealing is not required but for the nicest job, sand with #320 or #400 first. If you sand, use a HARD sanding block. A soft block allows the sandpaper to follow any bumps, ridges, etc already there. Use a hard block and do not run the block over the edge. It will round the edge. Keep all of the block on the blade face. After sanding, use a tack rag to remove ALL sanding dust. Any dust left on the blade will make a small bump after sealing. If you seal and you feel any bumps, use the block again and sand Very lightly. A piece of "used" sandpaper is much smoother than a new piece. Use a used piece if lightly sanding the finish.

By the way, this was for a NEW blade. If you have a used blade, it is a must to get ALL the old glue off.

If you REALLY want to sand and seal your blade then what hookshot said is the way to go for the sanding part.
I am inclined to NEVER SAND and NEVER SEAL my blades now. I just have to be EXTRA CAREFUL when I remove the rubbers off my blades.
Sanding and/or sealing makes another blade...I know I am stretching it a bit because I am surely not good enough to feel the difference between a sealed blade and the same blade not sealed. I just think the blade keeps its value much better when it has neven been sanded not sealed/varnished.

I can't speak for sanding but using only one coat of sealer does not change the properties of a blade. Only once you start using 3 or more coats will it make any difference (as well as start adding weight) But one coat doesn't change the way a blade plays.

Having done close to 100 blades, many in pairs so I could compare sealed to unsealed, I can tell you one coat is not detectable on an all+ or faster blade. An OFF + blade would need MANY coats before you could tell the difference. We have done blind tests with other players that could not pick the sealed blade. As far as holding the value, some like to buy a used blade that still looks like new. With the new water based glues, more reason to seal.

I work with various grades of wood every day, If you want a very smooth finish that will have no bearing on the playing properties of the blade, this is what you should do;
1. sand blade with 500s paper useing hard flat block going with the grain, then dust off with tack rag.
2. use a 50/50 mix of a quality sanding sealer and acetone to brush quickly over the blade surface.( this will give a quick drying, ultra thin layer).
3. as soon as its dry (about 1-2 mins) buff up vigerously with a soft lint free cloth.
TRY IT! YOU'LL NEVER HAVE BLADE DAMAGE AGAIN !

That is the safest and simplest way which I always do.
