Repairing a Water-Damaged MDF-Melamine Countertop
      #6382112 - 05/21/13 11:55 PM

Hello, I have an MDF-melamine countertop that has some water damage; the melomine separated from the MDF board for about 4 inches along the edge.

Any suggestions for best ways to repair this?

Thanks.

Ramone

Sorry, but Twinn's suggestion is about all there is. Depending on it's location, maybe the damage could be cut out and a butcher block inserted.

Do you think it's worth squirting some glue in and clamping it down to see if it holds? There's still plenty of strength in the board ... : /

You've got nothing to lose.

But I think I'd try construction adhesive or epoxy rather than glue.

Given the application, I'd guess that contact adhesive is out.

A pic of the countertop would help.

I agree that you have nothing to lose. I guess my question would be if it matters what it looks like when you're done.
A picture would help.
Is there an integrated backsplash or is it a flat piece? How is the edge treated? Was there damage to it?
One of the enemies here is going to be the surfaces- the top of the MDF and the underside of the laminate. If there is glue, dirt, or particle residue it will translate through the laminate and ruin the surface appearance. I would try to use a file, some solvent, and sandpaper to try to clean up the mating surfaces. For the same reason I wouldn't use construction adhesive, although I would agree with epoxy. Make sure to tape the counter edge and top of the laminate so you don't bleed onto those surfaces. Arrange your clamping pressure to go several inches past the patch. I would start clamping behind the part that peeled up and work my way forward, across the whole piece. Assume it won't work and the piece will be ruined and you won't be disappointed.

The first pic, by itself, of the lam pulling up----with ginger scraping and clearing the gap of debris should allow re-gluing. However, the damage underneath tends to expand the material, which will leave a bulge in the surface. If this is a repair to get you by until you replace the counter------

If you can get a hot iron onto the water damage, I'd see if you can get any shrinkage. If not, I'd talk a razor scraper or sharp chisel and try to scrape off any bulge on this material---your goal to level the area. Again, clean out debris and re-glue the lam. This isn't a great fix, but will buy you some time.
