MDF Router Table Top

[Steven Bolton]

I want to glue two 24 x 36 pieced of MDF together. Both would be 3/4 inches. What is the best way to glue and get it right? Does contact adhesive work.

I want it flat and I want it to stay together.

Thanks for input.

Solvent based contact cement works well. Some folks use yellow glue, but I think there could be long term problems due to the glue never curing fully, especially with MDF being weakened by liquids. I used contact cement and also used screws to pull the two sheets of MDF tightly together. Be careful not to put screws where you will make cuts for the plate. My MDF and laminated router table top has stayed dead flat for several years using this method.

I did use yellow glue for mine, but contact cement or even cold-press is a reasonable alternative. Be sure to use cauls and clamp it down to a flat surface as the glue cures.
