Here's a copy of the email I sent a week ago to VT Industries regarding this product (I have yet to get a response):
I recently received and installed several of your countertops: a 6’ which was fairly flat, one left and one right miter.
The 6’ top and the right miter top arrived together. The eight foot right miter had a worrisome bow, especially at the miter end. I laid it on a flat surface in hopes it might flatten out while I waited for the left miter to arrive.
When the left mitered top arrived a week later, it was significantly bowed and twisted, as were the long splashes.
The boxes didn’t appear to be bent, in fact they were very effective in keeping the tops cosmetically undamaged.
Returning the tops was not an option, as it was essential that I got this kitchen up and functional in the few days I had to work on it.
It cost me nearly a day setting-up the kitchen cabinets with blocks substantial enough to pull the warps out of the tops with screws and pocket screws to do a passable job.The splashes needed elaborate clamping and wedging to get them acceptably set.----- I’ve been a finish carpenter for forty years; I can’t even imagine how a DYI’er could pull it off!
I’ll attach a picture of how out of line the miter bolt pockets were. I don’t know how this might happen, but this issue was a side-show. I used a block to hold the two miters together to compensate.
The routing mistake at the miters goes into the dumb goof category, but the warpage goes into the bad process category. My guess is that they leave your shop in good shape, but that it’s humidity that causes all the warpage.
Sure seems like sealing the under/backsides would go some way towards keeping the tops stable in transit.
If I had this to do over, I’d either do my own laminating, or tile, even!
Life’s too short to spend so much time and effort trying to save a little time and effort!
I haven’t given feedback to Home Depot regarding the tops—I hope you’ve taken the time to read this and make the effort to improve.
