Default Best adhesive/method for laminating router table tops?

As the title says. I have two 18mm thick MDF pieces and a sheet of formica laminate, what adhesives/methods have you used with good success?

I'm planning on edging the laminated MDF with hardwood then sanding sealer the hardwood edging. I will be making a hardwood framework on the underneath of the MDF which will then sit inside my router table shell/frame.

Thanks

Also, if I'm adding a hardwood framework on the underside of the TOp, is it necessary to laminate both faces? I'm sure the hardwood framework should keep things flat enough for the forseeable future!?

Regular wood glue works fine for the MDF or adding your hardwood trim. Once these have dried use a contact cement to attach the Formica top and bottom. This adds a tremendous amount of rigidity to the top and is the method described in Shopnotes #1.

I have had good luck with the 'nasty smeling' weldwood cement, so-so luck with the water based. If you are going to be as thick as you describe, laminating the bottom is optional, you can seal it with a finish. Most laminate counters sold aren't laminated on both sides.

Just my opinion

I've had good luck with the 'nasty smelling' Weldwood cement, too.

My success rate improved dramatically when I started rolling on two light coats each for the laminate and the substrate. MDF soaks up adhesives like crazy and two coats guarantee coverage.

Give it a try. I promise, the laminate will stick better and longer.

If you do not like the smell use the 3M spray contact cement. Use on 1 piece for semi-permanent and both pieces for permanent. This works for both the MDF and Laminate. Unlike Mike I always use shellac on all MDF products because down south MDF is anything but waterproof and the humidity will eventually cause swelling. It is cheap insurance, does not interfere with the spray contact cement and if you do not believe it, toss a untreated chunk in water and watch it swell.

Good luck - Baker

Living in AZ, I never gave a thought to the swelling of MDF in humidity. Good suggestion Richard. I'd imagine it can get humid in England.

I might be a bit pedantic but I have laminated both sides of 1 1/2 inch ply to eliminate any possibility of bowing and ensure good sealing. The ply was actually 3/4 glued together. I used white laminate so as I can do calculations, etc. on it with pencil. The pencil rubs off easily with alcohol.
