Question
I glue two sheets of Oriental strand board together (4x8x3/4) to make one 4 x 8 x 1.5" sheet. I was using contact cement, which worked the first few times I used it. But since, the sheets aren't bonding together totally. Can you suggest something better? And a reasonable price? After bonding, the sheet is cut into 6" wide strips.

From contributor P:
I think the difficulty here isn't the glue, as many will work (Titebond II or Titebond III, for example). OSB is so un-flat, your main difficulty will be achieving a good contact between surfaces. If you don't have a full sheet press, a vacuum bag on a flat surface should work. Otherwise, I would suggest ripping your strips a little oversized and clamping a whole stack of them the good old fashioned way - lots of clamps (whatever you have - Bessys have a good, deep reach).

Comment from contributor W:
I have the same experience with osb panels not bonding together. I received a recommendation per the people at osbguide.com and franklininternational.com (titebond):

OSB panels use a bonding/waterproofing resin to secure the wood chips. This resin may bleed to the panel surface during fabrication, coating much of the bare wood. For any adhesive to work on the panel surface, it would have to be 'solvent based' to react to the resin as well as the wood. Water base glue won't work. Sanding the panel surface will also help as well.

Suggested use:
Titebond solvent based FRP adhesive, Titebond trowelable multipurpose construction adhesive, or other brand equivalents.
