Buying veneer backing paper??

[Peter Sefton]

Thanks again for all your advice.
I contacted Crispins and they informed me that they had no access to a paper that could back veneer, or the whereabouts as to where I could buy such a product.
I bought a couple of different gummed brown paper tape, but the adhesive wasnt strong enough to hold the veneers secure when peeling the masking tape off. ( I use masking tape to build/construct the parquetry sheet. )
I have however made a A3ish size press/clamp using 18mm MDF with several bolts around the edge This allows me to clamp a pre made parquetry sheet coated with a 1:4 PVA mix to a piece of brown parcel/wrapping paper.
I have had success on some small sheets, in that after I have glued the backed parquetry sheet to the ground work, I just dampened the brown paper with a sponge and it just peeled off.
However on larger sheets, I have found that the PVA doesn't dry, I assume, due to the lack of oxygen that is within th press/clamp.
Could you please advise of a adhesive that I could dilute that doesnt need oxygen to go off, that will alllow me to dampen it after setting to remove the backing paper.

Many thanks

Simon

I do not use the method you are trying but I have used Solvite wall paper paste on occasions in woodworking it might just be right for your application.

Thanks again for all your input, it has all been taken on board.
Perhaps my methods are slightly unorthodox, but I only do this as a hobby and have no access to a workshop or workshop machinery or vacuum press. All my work is done using hand tools, thus the primitive MDF press.
I will certainly try the starch glue and the wallpaper paste suggestion and let you know my findings.
As a final question: Do both of these adhesives need natural air to cure them, as I am having problems, as stated in my previous posts, in that the adhesive is failing to cure due to the lack of air.

It's probably a question of experimenting with different things till you find something that works. I have had no problem with hide glue going off in the press, even on much bigger pieces than A3. How long do you leave it in the press for?

Thanks marcus
Like I have stated, it is a primitive press. I have left it clamped between the MDF pieces for 2 days, with total failure, but have learn t that if I open the press after 36 hours ish and use a seam roller over the entire sheet and then put it back in the press, it normally works, but not always.
I am really looking to find a technique that I am confident in working each time without opening the press

I would say it is unusual for any glue not to have cured after two days, is your press the problem? I understand you have thinned your PVA 4:1 this may be too thin, as I say I don't use your method but I only recommend thinning glue by 5% for woodworking. PVA cures by solvent loss the water soaking into the substrate so 2 days should be plenty of time. One of my guest lectures is in next week Quentin Smith http://www.qjsmarquetry.co.uk/index.php he is the president of the marquetry society http://www.marquetry.org/
Quentin is a really helpful guy and very experienced I would pose the question to him next week but I am going to be setting up for the Midlands Woodworking show http://www.nelton.co.uk/assets/files/mi ... l_2014.pdf give him a ring or email he may be able to help you out or if all else fails come and join one of our short veneering courses.
