I have a dining table top with a repaired veneer finish. It has had three
coats of waterbased Ronseal called 'Diamond hard varnish' put onto to it.
Trouble is, that if water is not wiped off staight away from this varnish
(and say gets trapped under a flower vase of water); it creates a white ring
stain.

I want to put on an *oiled* based coat and phoned ronseal technical help
line to see if it was ok to paint their oil based 'ultra tough varnish' on
top of the water based diamond hard varnish. They said it was ok to do so..

I forgot to ask them if the oil based ultra tough is a *polyurathane*
varnish or not, and their office is now closed for the weekend. (i want to
do it this weekend). I cannot find whether it is or not a polyurathane
varnish from their website.

Is this ultra tough varnish likely to be more *scratch resistant* than the
diamond hard varnish already on the table or not, would you say?

Also it comes in three finishes; gloss, satin and matt. I would prefer to
use the matt, but have been told by someone that usually gloss is more
hardwearing than matt paints. Do you think that it would make much
difference between gloss and matt with this ultra tough varnish? * *Thanks
for any advice.

The additives to dull finishes make them softer so yes gloss is harder
but they also make them cloudy, for floors or any wood I always have
the first coats gloss then the final coat satin is put down, this
gives more wear and more grain is visable. 5 coats of satin and woods
beauty of the grains colors will be masked. I would use the gloss then
hand rub out the finish for a real smooth hard clear look. If its nice
wood you build layers, up to 7 total with the old finish, you can just
use 0000 steel wool or use Rotenstone and oil, If they said you can
use Their oil poly over Their water base thats great but I have had
issues changing products before a near 6 month cure time of the old
finish with using poly over oil Varnish, nightmare issues. The oil
base is much more solvent than the water base and can seriously affect
whats on the table now, But they said its OK!!, so you should be fine
[ I hope]
