Glue for mdf panels?

An experienced woodworker/cabinet maker would be the best person to query.

I have had one use Liquid Nails, there are several varieties of that product.

Some of the first ones I had to reclamp and squeeze in glue because of a slight seperation, but mine are huge. The most recent cabinet maker has done a better job and I have not had that problem.

My husband is an architect and part of his job is recommending certain products for construction. One of those products is glue, and he has decided to go right to the top for the answer to this sticky problem. Forrest Products is the ultimate authority on glue (they set the standards for the industry). He happens to know someone there, so I should have the definative answer on archival glue for wood products soon. I guess I should have asked him to begin with.

Here is the back of the panel, all the mitred joints have little "footballs" inside (don't ask, I don't know). We looked at many different types of bracing, and I consulted books and websites. Everyone has an opinion about how to do this, and they are all different. So we are trying this, it is solid as a rock and smooth on the edges, so if I decide to, I can paint the edge and not use a frame.

When I get the answer back on glue I'll post it.

They are called biscuits, I believe.

How big is this panel , what is it braced with , how thick are the sides, the MDF and how much does it weigh?

Be sure to lightly sand the MDF before gessoing it , to ensure proper bonding of the grounds.

The panel is 30x40, braces are pine (untreated) 1 5/8" wide, the sides are 1'" thick, and the mdf is 1/4". I'll be sealing the whole back side of the panel with gesso. The panel weighs 13lbs.

Steve is building a press to help put even pressure on the panel while the glue is drying.

I'm already roughing up the surface of the mdf, It just made sense.

Another question for you, if I use this panel for my tatto guy, I will have a 9 1/5" head. Of course this will make him larger than life! Do you think this is too over the top, or appropriate for a bodybuilder?

Drop the 1/5". The standard male head is 9" high. Are you using a 71/2 head or an 8 head classical measurement.?The topic "Head size " discusses this at length.

Jean Kelly · 04-19-2005, 02:04 PM

Oops! That was supposed to be 1/2" not 1/5". I shoot for the 8 head model. Jux needs to be massive, at this scale his right upper arm will measure 5 3/4". I can easily go for a 9" head. Thank you!

My husband is the above. Did custom homes, custom cabinets, stairs...etc for many many years. And his father before him and his father before him. He says Guerilla Glue.

I have no problem with Guerilla Glue, but the men in my life are on a quest for the holy grail of glue!

How necessary is it to cradle mdf panels?

I think that MDFpanels at 1/4" x 20" x 30" would do fine without any support on the backside, but it looks good. Bigger formats should be cradled though.
I also believe that we should do these little things for our clients if they like the look of it.

I have made several paintings on Masonite 1/8" x 24" x 24" and never had any problems with them winding. Normally I prime both sides to avoid moisture to bend the panel.

1/4" MDF panel would be more stable than the thinner Masonite.

I could be wrong, Allan
