Subject : gluing raw veneer using unibond
Posted : 2001-05-10 5:51 PM
Post #30131

Dary,This is my first time veneering. I am ordering some Unibond to glue raw bubinga veneer to some mdf cabinets. I want to use the Unibond vs PVA so I don't have to worry about the PVA moisture checking the veneer as it did on some samples I glued up. I do not have a vac bag and so planned on using clamps. The cabinets I will be gluing the veneer to are about 40"x15" and 40"x10" in size. Will I need to use cauls (if so how to construct them) or will it suffice to place another sheet of 3/4" mdf over the veneer and clamp every 8 inches or so? Will there be enough bleed through the with waterfall bubinga to worry about the top piece of MDF getting glued to the veneer? Any other tips?Thanks for any advice you might be able to give.Kind regards,Dennis

Dear Dennis,I suggest doubling up your cauls so they are 1 1/2" thick and clamp about every 4". Be sure your clamping pressure is all the way to the center of your 15" wide panels. It's not so much that you need very high pressure, just very uniform pressure. I would put plastic between the cauls and veneer because you will get some bleed through, in fact you should. Be sure to veneer both sides so you will need 1 1/2" cauls on both sides of your panel. Also, spread the glue with a foam paint roller to get a uniform coat.Good luck. You may want to consider a vacuum press, it would make thing go a lot easier.SincerelyDarryl Keil: Dary,: This is my first time veneering.

Daryl,Thanks for the reply, I appreciate it very much. I will use a double thickness of MDF as my cauls (I was under the mistaken impression that cauls were slightly curved "2x2" boards you placed aceodss the width of the piece and attached your clamps to. Do I need these in additon to the two layes of .75" mdf?)One other small question, Will a gallon be enough to glue up 35 sq. feet? If so can I use the leftover just like I would wood glue for other projects?Again thanks for your help.Regards,Dennis : Dear Dennis,: I suggest doubling up your cauls so they are 1 1/2" thick and clamp about every 4".

Dear Dennis, Because your panels are not very wide I think you can get away without the additional 2"x 2" wood blocks although they would help. I am assuming you have the wooden hand screw type clamps as they put pressure over a 4" to 6" area depending on there jaw length. If you dont have any of these clamps then you will need the blocks, at least on your wider panels.A gallon of Unibond 800 will cover about 250 sq.ft. and the extra can be used for general wood gluing.SincerelyDarryl Keil: Daryl,: Thanks for the reply, I appreciate it very much.
