Polyvine - anyone used it?

[RogerS]

Tempted to give it a go to see how little it discolours Birds Eye Maple as it's water-based.

Has anyone tried it?

I have never heard of it but if you want to polish birds eye maple or any wood that is light and do not want to alter the colour then bleached shellac will do the job for you. it is also good if you are polishing over metal or ivory inlays as it will not tint them. The only disadvantage is it tends to be a bit brittle and will scratch more easily than unbleached shellac.

 

[RogerS]

Thanks for that suggestion. I'll look into it.

First attempt using Polyvine left a lot of brush marks. On the plus side, discolouration wasn't too bad.

While digging around for some bleached shellac I came across this interesting research paper on shellac and minimising discolouration

interesting Roger. What are your conculsions- will you be avoiding bleached shellac as a result?

 

[RogerS]

No, not at all. I'm going to give it a try as I thought it came out pretty well for colourless finish.

i missed the last but one paragraph. I need to get some for some ah I am finishing actually. Smith and Rodger seemed to be as competitive as anywhere I could find.

Bleached shellac seems to be elusive. Any suggestions? I've tried Smith and Rodger, A G Woodcare, Fiddes.

 

[marcros]

is smith and rodger's waxy white, or transparent powder the same thing?

 

[RogerS]

They say it is clear but not specifically bleached. I'm getting some in to try.

Ian at S and R is very helpful. he is on here too I think- woodfinishman IIRC

Bleached shellac is sold as 'White Shellac' it has a cloudy white appearance but will be completely transparent when applied.

I bought some of that to try. I'd have said it was a more cloudy brown colour TBH! I've got some other stuff coming down from S&R and so I think I'll sand up a long piece of BEM and run a test. I'll try and take some photos.

Thought I'd take a photo of 'white shellac' and normal Shellac Sealer. The allegedly 'white' one is on the left!
