Stripping polyurethane varnish
« on: February 03, 2010, 16:37 »
I've acquired a lovely big old pine table :) The top has been done with polyurethane varnish which I would like to take off.  Will Nitromors be OK to use or can anyone suggest something better. 
OH wants to do it with the belt sander but I think that will remove too many of the bangs and dents that makes it look its age :)

What do you think :)

I stripped my dresser with nitromors, it worked a treat...........be careful you don't splash it anywhere though :ohmy:
Then a hand sand :) are you just going to wax it Spana, or oil it?

have it dipped,

the finnish of the wood will end up 100% better than paint stripper and sanding it out

you will find a number in the yellow pages or someone like that.

we used to do loads of work on heritage propertys and on a regular basis had stuff dipped, this is good advice from someone with experience in the wood re-finnishing trade

thanks

If you have pine dipped it comes out that horrible orange colour..........which I hate :(

I had several doors dipped years ago and wasn't happy with the colour, I ended up lightening them with liming paste in the end!

and the dipping loosens the joints.......

Mumofstig is right, and not only that but there is usually quite a lot of works still to do in smoothing down etc.

Nitromors and patience, a good pair of gloves and plenty of newspaper will do the job a treat Spana

and oh yes, a good dollop of elbow grease too  :D

Great sense of achievement to follow  :nowink:

have it dipped,


I quite fancied this idea, thanks Nathan, but OH said same as you mumofstig, that the caustic soda used would make it a horrible dry colour and melt the glue in the joints, not that we have ever had anything dipped so dont know how he knows ::) :lol:
So it looks like the Nitromors if that will do it :)
mumofstig, I usually wax things but i'm never really happy with the finish.  It always looks over finished to me, do you think oiling is better?

I am not a in favour of dipping furniture or joinery either, it may be the easy way but as said earlier can kill the glue joints and make the wood soft and wooly.
Nitromors & elbow grease is the way.

Did you mean treated as a hardwood ?, pine is a softwood.

no,

a diffrent product is used to dip pine.

there is a softwood dip, hardwood and pine.

some places will just dip pine the same way they dip a normal soft wood, then it will discolour.

when pine is dipped the correct way it wont take on or loose colour and the serface wont splinter like it does with a basic dip

Is that with danish oil, i only used it once and the finish was quite shiny :unsure: 
OH made me a wonderful wooden wheel barrow about 15years ago with a wooden wheel  - i wonder how many people have had 3 fittings for a wheel barrow :lol:- and we finished it with Danish oil and it still has the shine today:unsure: 

Infact i find it really difficult to get the sort of finish i'm after, I think most thing i do look more finished than i would like.  Any tips new2veg :)

look into wax'es then,

can get a nice satin and matt wax.

but do yourself one thing tho,

dont buy the cheapest wax go for mid price upwards, you will struggle to get  a good finnish and seal the wood with the cheaper stuff.

danish oil will have a sheen, but if its loaded on yes u will get a shine and when its hardened up a while can even buff it

I think oil is the way to go, but apply a very little at a time, just to feed the wood and stop before you get any sign of a shine. Use Danish oil, or if it's for a 'working' kitchen table food grade mineral oil :)
