Beginner here.

I’ve got a spalted slab of living edge tamarind, 78×28 x 3, destined to be a bathroom vanity.

I sanded the wood all the way from 40 to 800 grit, using an orbital sander.
That was overkill, apparently.
The wood seems incredible dense, and now feels like glass. Do I need to go back and roughen it some (220 grit) before I start applying varnish?

Finishing plans:
5 coats of epifanes high gloss marine varnish
2 coats of epifanes matte finish
(24 hours between each coat)

Main tips I’ve gathered from reading online…

minimal dust, well ventilated area
clean bare wood with mineral spirits before applying varnish
1st coat gets thinned slightly using mineral spirits
lightly sand between coats, increasing grit each time
high quality china bristle brush
also seal the bottom and sides

How does this sound?
