What stain did u use to make the cabinets that grey color . I love this color and I am making my cabinets out of knotty alder too

This was a custom stain mixed in our paint lab for this particular customer. Are your cabinets Crystal Cabinets?

We have Knotty Alder Cabinets and are uncertain if they are from Crystal Cabinets as they were installed by the previous owners. I would love to stain them like the picture above. Is there a way I can find out if they were made by your company? (i.e. specific branding on the inside of the doors or anything.. I can't seem to find it if so). If the cabinets are already stained a brown, they would need to be sanded or stripped and restained, correct?

Sorry for the late response. Crystal Cabinets would typically have a brand label on the upper drawer of each cabinet. To answer your last question, we do not do refurbishing of cabinets, only new. But if this is a do it yourself project, they our guess would be yes.
