New Formica over Old Formica
We are looking to change counter tops, counter it self in very good condition,just looking/wanting to replace tops vice entire counter, local cabinet/counter says he does not recommend formica over formica but whole new counters with new formica or what have you yet I found couple web sites that more less say go for it . Welcome Comments / Inputs, Oh I AM NOT doing it my self ,just paying for it as per usual . AL
I wouldn't do that, tear out the old ones and put in new ones,
About a year after getting a new home in 1991 all the counters, cabinets, and vanitys had slabs of formica peeling. The red adhesive supplied by Wilsonart was bad and they made good on a national level. For just a kitchen counter perhaps you could do the demo and upgrade with the money saved.
---First you have to clean the existing Formica with a strong cleanser to take off all the dirt and grease.
----Then sand the gloss off the entire surface with 100 grit paper.
---After that wipe the whole thing down with lacquer thinner.
---Then use contact cement and glue it down.
I've done this on at least a dozen jobs and it never peeled. The most important thing is the sanding.
Thanks for input's Al
