My big box (maybe Costco) work bench came with 3/8” sheet particle boards for the top and bottom shelf. They were pretty thin and after years of use.. the top soaked up liquids, got stained, and had swollen lumps on it.
I thought I was clever the first time I tried to solve this, by flipping the top over and BAM! I had a new looking top. I may have even sealed it with a coat of poly.
Then.. I searched for new and used “butcher block” tops. Not
real butcher block with the end grain on top.. but stuff from Home Depot, Grainger and Amazon as well as used from Facebook marketplace.
I found one by Husky on FBMP for $100, cut it to fit (my first real use of a circular saw), and replaced the particle board top with it.
I love it! It’s got a few dings on it now.. but nothing worth complaining about. I keep a silicon mat on it to keep the top clean and to prevent more dings.
I took the particle board top and moved it to the bottom shelf so that’s twice as thick now. Ignore the table top I have clamped in a vise on my WorkMate. I’m just reusing this picture from a different post.
