To sand, or not to sand?

[solo]

I'm using some Ronseal, satin, quick drying varnish in the house. The tin says to sand with fine grit sandpaper before the final coat. Just wondering if this is absolutely necessary, cos I'm getting fed up to the teeth with this project and just want it done.
TIA.

Only necessary if you want a decent finish!

Do exactly what it says on the tin!

The finish isn't too bad at the minute, so I'm trying to understand the justification behind sanding before the final coat. By that reasoning, I could apply 99 coats and then sand before the 100th. Just wondering what the sanding actually brings to the job if you see what I mean.

The sanding before the final coat gives you a smooth surface with a decent key for the final coat.

If you're happy with it as it is then no problem - carry on as you suggest

As said, sand lightly using a very fine wet and dry paper (generally between 600-1000 grit, as this shouldn't scratch the surface) for the best results, then wipe off any dust completely before applying the final coat.
The main reason for sanding is not necessarily to provide a key, but to remove any nibs that have built up during the previous coats. You may not think the finish feels bad at the moment but I'm sure you'll be surprised by the difference after a light sanding.

Well, I sanded and am truly impressed with the finish. Just goes to show, it pays to follow instructions sometimes. Thanks for the replies.
