Thread: Laminating large sheets of timber

Use thickened epoxy!

Liquid Nails would be at the bottom of my list.

I know everyone will tell you PVA works and all that, but just get a nice honey consistency, cover the whole thing, let it slump dead even then drop the top sheet on - no airgaps!

The epoxy doesn't rely on air to "dry" and in a day or so will be perfect. Just make sure that the MDF is dead flat, because you won't be getting any warps out later!

Epoxy would be great except for the cost - I have to laminate two sheets of 900 x 600.

Paul,

If epoxy glue is too costly you can use any pva glue and, in the areas where you don't need to rout or cut anything, do as Norm would say secure the two panels with brads.

I did this when I was building my router table extension fences and have had no problems.

This may be useless so shoot me down if ya wish. What about a contact like Gel grip, you can spread real even with a notched spreader, let it get tacky, then whack the other sheet over the top like Bob said.
Not that expensive. Dunno what everyone else thinks?

I believe there would be no real need to place these under pressure as the surfaces should be perfect -just a few locating screws to ensure the two panels are registered ..... in addition I feel "yellow" PVA or similar will be fine - combed across the entire surface and wiped off edges...... should dry fully in 24 hours. Finally, as the table doesnt really need to be "strong" in the usual sense, this bond should be more than ample.

Hope that's helpful

Would contact adhesive be an option? Otherwise I'd probably go for
tradesmans choice by Selleys.

On the above product does anyone have the 'formula' for the date of manufacture in their code nos. Someone in the company gave me the secret formula from the packaging once and I've lost it. The stuff only has a year's life I believe?
Any info?

My router top is exactly that, scrounged from a shop-fit throw out pile, and after Six years the darned thing is starting to delaminate!!! I'll have to try to get my money back!!

There is some load and vibration through the top so obviously it couldn't hack the pace.

I don't think the contact is the best choice, I'd go with the PVA spread evenly over that area, particularly if you give both the surfaces a good sand first, thers is no way you will get it apart.
clamping? a few screws that can be removed later would be ok or put it on a flat floor & stack your worldly possesessions on top.
