Hey guys,
I have a karri burl that I will be finishing with lacquer. However I need to apply a coat(s) of sanding sealer beforehand to make the fibers of the burl stand on end, so I can sand at a higher grit and produce a truly smooth top when the time comes to finish the burl.
Any recommendations on a cheap, effective sanding sealer?
Thanks,
Harlan
Hi
Feast Watsons sanding sealer is good.
Not sure if its the cheepest though.

There seem to be two completely different styles of sanding sealer on the market.....
The Ubeaut stuff (which I use) is a thin liquid with no suspended solids. Raises the grain, but dries in a very thin coat. Feast Watson, by comparison, is much thicker with a LOT of material in suspension. The last can of Feast Watson I had (and I won't be buying more) had a large lump of putty-like material in the bottom, which took a lot of stirring to get rid of.
I gather the Feast Watson is intended for a rather different application, i.e. painted finish?
Mr Brush
as far as I know, people use "sanding sealer" for two different applications
1) to raise the grain and
2) to fill pores as the first step towards a glass like finish
Ubeaut's stuff is for use 1)
Feast Watson's stuff is for a use midway between uses 1 and 2
Watyl make a grain filler prmarily for use No.2
If the Wooden Mechanic is looking for a glass like finish, multiple coats of the Feast Watson product may be the go
Hey guys,
Thanks for the replies. I am only wanting to get the grain to raise, The top feels perfectly smooth however when any sort of moisture (water) is applied to the surface it again becomes very rough and is unpleasant to touch.
The whole idea of me using a sanding sealer is to raise the grain for it to be sanded off at a higher grit (400, 600, 1200 etc) and then finished.
I will have a look around but will most likely use the U-beaut Product as the description sounds much better than a thick lacquer like consistency as described for Feat Watson's Sanding sealer.
Thanks guys,
Harlan

if you're finishing the burl with multiple coats of a sprayed on solvent based lacquer, you should be able to use a thinned lacquer coat as a sanding sealer and then fill the grain (pores) with more coats of lacquer
one of the functions of a sanding sealer is to remove the need to sand much beyond about 320 grit
the finer grits are then used to "polish" the top coat of lacquer
Another option, if you are after a very quick fix, is to lightly wipe the surface with metho. This too, will raise the grain, but has absolutely no grain filling abilities.

hi there i use ppg sanding sealer you can only get it in 4 liter tins i think i payed $35.00 i got it from like a paint place ,so i got ppg lacquer that is compatible this is what i did my burl with and it is very smooth i just wiped it on and than just sanded with 1400 :U
looks great mate, well done! :D
Absolutely beautiful, lonepine. Well done! I am green with envy :)
I am trying to understand the various ways of finishing, not having much luck with my finishing efforts to date.
What did you finish the bare timber with before applying the sanding sealer, and then what did you sand the sanding sealer coat with?
How many coasts of ppg lacqer did you apply, and what did you sand with between coats?
Thanks ok i just sanded to like 1200 than the resin was to smooth for the lacqer to stick so i used a 3M paint scourer than i put 3 coats of sanding sealer than aboat 6or7 coats of lacqer:doh:. Than letting the second coat dry for 48 h than i sanded it with 2000 wet and dry. And the other 5 coats without sanding. And just to add i sanded the sanding sealer on the thired coat after i let it dry with 2000. thanks :UQuote:

I wasn't aware that ubeaut did a version, when I run out of this batch I might give it a go
