Question from Karen
We are in the process of replacing our countertops with a product called Granite Transformations which is an engineered stone product made of 95% crushed granite and 5% resin to hold it together. It creates a non-porous surface that doesn’t have to be sealed like regular granite does. It is only 1/4 inch thick and is glued down with an epoxy resin adhesive on top of your existing countertops so there is no demolition and disposal of old countertops. I’m wondering if there are any potential health concerns from using a product like this, particularly from the resin that holds it together or from outgassing from the adhesives used to install it? In your opinion, is this a “safe” product to use?
Debra’s Answer
Without seeing a sample of this, I can only answer in general about engineered stone. I’ve seen many samples of different kinds, and have never noticed an odor. It appears to be extremely hard and inert. Can’t speak for your exact product as I have never seen it. Also, the amount of resin is extremely small in comparison to the amount of stone.
The epoxy glue contains toxic chemicals that will smell to high heaven during application, but once it is cured, it will be inert. Also, whatever fumes that may be present would not get through the engineered stone.
I like the idea of installing these counters over the old ones.
That said, this is an objective evaluation only, I have no experience with this.
Anyone have experience?
With Granite Transformations over Formica, you will still have outlasting formaldehyde from the Formica base which will not be covered.
That is correct, but you can seal the exposed underside with aluminum foil to block the outgassing. On top the formaldehyde won’t go through the countertop.
