Subject: formica counter tops
Date Posted: 08 Feb 2025 at 12:17pm
After 17yrs our custom cabinet Formica counter tops are starting to come unglued. Is there a way to re-adhere them? All I can think of is peeling and applying contact cement but keeping everything aligned could be a challenge. I doubt applying heat to effected areas will work but haven't tried it yet. Any ideas?

hmm...doesn't 'our' want NEW marble of quartz  ??Wink

You 'might' be able to gently use a heat gun and a lot of 2by2 as spacers to pry up the Formica, evenly spread contact cement on both surface WAIT until dry, then lower it back on and roll it.

If its just a small area, you might try pry up and inject some thick superglue, and then clamp or weight down.  I think you will pull up some substrate, if you try to pry up all of it... Also you might try the Super glue that comes with the accelerator.  Lowes, around here stocks it for about $16.00.

Super glue "accelerator", otherwise known as baking soda?  Works well enough for the fly boys to use it to patch chips and nicks in props/helicopter rotors from what I've been told & definitely causes it to set near instantly. (Can't recall when I learned that trick, but used it to good effect building back up some broken plastic where chunks were missing.)

Likely too fast hence useless for counter tops, just felt the need to share that baking soda does make the stuff set pronto.

Age is not your friend with the adhesives used on these countertops, Chemically they dry down, release all the Volatiles until the base adhesive carrier dusts out, at which time would either have to strip off entire cover and re-adhere with counter top cement or replace counter tops.

A heat gun might reactivate the adhesive. If it doesn’t I think I would replace the whole countertop rather than trying to reglue the formica. We have a couple of local businesses that will make custom countertops to your measurements and I think that they may come out and do the measurements themselves. If they use your measurements then you get to do the installation.

Sometimes the lamient pulls because of humidity that soaked into the particle board.. not that the wood is WET... just long term humidity.... like others, i would guess you will not have much success with large areas... minor repair of a corner or edge might work..

I needed a CUSTOM counter top that was 27 inches deep instead of the standard 24... I went to Menards and they had samples and FORMS to fill out and order... Worked OK.

Nope, never used baking soda, the stuff I'm talking about is aerosol can, kinda smells like Windex.  When sprayed on or near unset SG, causes it to set real fast, looks like its smoking...

Here's what I am talking about:

Not saying its right for a large area, or all substrates.  I use it a lot when turning wood on the lathe, works great for small to medium cracks in the bowls I turn...Wink

.

Get a can of new Formica contact cement and pry up the loose sections and coat as if putting new down using thin lathe to keep separated. Roll for contact.

Otherwise, strip and put new Formica down. You'll need an edge trimming router bit and router ($20 harbor freight trim router will do it).
YouTube for the detailed how to. It's pretty easy. Formica was pretty inexpensive last kitchen I scratch built. I think I put the circular saw blade on backwards to cut it without chipping. Now I might try a die grinder and cutoff wheel.

Managed to get some glue worked in the edge with a putty knife and under the end strip. It's better than before.Granny's clothes iron was used as well with mixed results....This area is "std" countertop which makes a 90 and turns out toward you. A little scary thinking about peeling up and total re glue with contact cement because I have a 45 and two curved down edges to get in place all at once.
