Question
I read a 3/2/2009 question about refinishing a venerred tabletop. After stripping what about sanding?  This large DR table has some damage and will need some filler.  Will each setion need to be sanded separately in the diretion of the grain?  What about sanding (with 000 steel wool)  between coats of polyurethane? Does grain direction matter then?

Answer
Hi Ginger
Nice to hear from you.
If you have read my posts about refinishing veneer, I always say its no different than finishing solid wood..as long as the veneer is in good condition.
I also always say never sand pieces we are refinishing unless there is wood damage.
In the case of veneer, great caution must be taken if you absolutely must sand. You can sand right through the veneer and ruin it.
Just because you must use some filler does not mean you must sand the entire top.
Yes its always good to sand with the grain but in some cases its impossible. It sounds like your table has inlays going in different directions. You cannot hand sand each direction sucessfully. You will have overlap sand marks which will ruin the look of your job.
So try to only sand where necessary over the filler. Try to be very gentle so you do not change the color of the wood by sanding too deeply.
Use a sanding blockwith 600 grit paper. This will ensure you do not go too deep.
A random orbit sander in the right hands with correct sandpaper is very good for sanding inlays like your table has but only if you are experienced with one.
And your suggestion of steel wool between coats of poly is sound.
Sounds like you are really thinking the job out..good going.
Kind Regards
