Since when are countertops 1. plastic 2. soft or 3. painted?
Just an FYI to followers of the post - from a non-expert, but a considerably “handy-man” type of guy… I’ve built countertops from “Formica”, natural materials (granite), “Corian”, ceramic tile, even concrete!
1 - “plastic”
Formica is plastic. Corian is plastic. They are man-made “engineered” materials.
“Formica” is a layer of plastic pigment/patterns bonded to a backing layer, covered with a thin, clear top layer. This “veneer” is glued to a sheet goods (plywood/MDF) sub-structure to give a finished surface to the exposed area.
“Corian” (or similar) is a plastic composition of granular pigment items bonded in a “medium” of a carrier component, that is extruded into a sheet. This sheet of material can be cut/machined/composite-glued into nearly any shape (almost seamlessly)… cool stuff, but spendy!
“Granite” is just that - rock. A slab of rock has been sliced from a quarry, been cut/trimmed/polished in the form of a finished piece - and set on your cabinets.
Ceramic Tile is clay. Clay that’s been cut to a size, coated with a glaze or pattern, and fired (baked under intense heat). The result is a very hard (but brittle) square of material.
2 - “Soft”.
Take your biggest “Chef’s Knife/Pig-Sticker” and jab the tip into your countertop!
Did it make a gouge/mark?
Then it is “soft”… Only granite or ceramic tile might survive this test… stone or ceramics are harder than, or equal in hardness to steel. (They use
diamond-coated blades/media to cut & polish stone/ceramic.) The biggest risk is a crack… NO fix for this other than replacing the tile/section.
With “Formica” you’re pretty much stuck. Once that very thin top layer of clear/gloss overlay is broken you’re left with what you’ve got.
With “Corian” type materials all is not lost. The pattern is throughout the thickness of the product. A gouge/burn can be sanded out, and the product re-polished to a like-new finish…
3 - “Painted”
The surface is as only as good as the product applied.
It’s a question of hardness, abrasiveness, speed, and ultimately water.
Water will eventually cut through rock… given eons (Grand Canyon for example)… add some abrasive and it will cut faster (almost humanly acceptable time)… add some chemicals and it will cut faster yet (Saturday’s clean the bathroom time).
Sorry for the “Handy-Man home materials update”, but this is the reason for the warnings on the label. There is a cost to speed & convenience… that’s why you bought the product!
