Topic tags/keywords: question

I have an 8’ folding conference table with an MDF top. It was left out in the rain and now the top has turned to oatmeal. I want to put a new top on the metal frame and am thinking of using recycled plastic deck boards. What do you think? Does this material hold screws well?

How will screws be incorporated for attaching the boards to your existing metal frame? I would think it may be better if you could use countersunk bolts that go through the boards and the frame rather than hoping that the screws will hold over time. If this table is going to be constantly opened, closed and transported around, screws might wiggle loose and may not be ideal.

That being said, I’m pretty sure deck screws are the commonly used fastener when using composites for building a deck.

I could bolt through, but would rather keep fasteners hidden.

The only negatives I see with deck boards in this use are that they are very heavy, especially the thicker ones (obviously); allso, that if they have to span much distance, they may be too flexible. I wouldn’t be very concerned about fasteners, unless the table will be subjected to a lot of stress.

I’m assuming there would be no reason to fasten into the ends, in which case they are somewhat prone to splitting, though not as bad as mdf moldings.

My plan was to tie the planks together with battens; one on each end and one in the middle. At this point, I’m treating this as a “wood” project and employing wood working techniques. I found some planks at Lowes called “choicedek”. They are 1” thick, 5.4” wide and 8’ long. Cost $14 each and 5 required. According to online press, they will accept wood screws with no problem in the usual wood working practice. Thanks for your input. The table will be heavy, but I don’t intend to move it around. It will remain outdoors as a picnic table and maybe use it as a bench rest.

I think the composite deck boards will work. Another option might be MDO. The only issue with the composite decking might be:

-the weight
-it might get very hot if left sitting in the sun
-it may not be smooth—only a concern if writing on it (without a pad or buffer) is important.

On the plus side it won’t ever need a finish! I wonder if you can paint that stuff?

Deck boards will sag over an 8’ long span especially in the summer. I doubt that this idea will work.
