Yep. That's nothing to screw around with. Take it to a pro shop that makes 'em.

By coincidence, just today for grins and giggles I tried trimming a 1x3 piece of marble with a diamond blade on my grinder. No matter how slow and careful I was, it chipped and flaked six ways from Sunday.

Fortunately, it was a waste piece that was being discarded anyway.

Wood working tools work on it. (It's plastic & resin with some marble dust)

Big piece to cut off use a skill saw. Just a smidge you can work it with a belt sander. Wear a mask!

I have had good results with a 24 tooth carbide blade, cutting from backside and starting from top edge of backsplash, then from front edge of counter, meeting at intersection. Be carefull to support so that the end of the cut doesn't cause chipping. Can be scribed to wall with medium grit beltsander, being careful of rotation direction to prevent chipping.

Re: Cutting A Cultured Marble Counter Top


Like Mike said, turn it over,
cut it from the back, and
support it so the cut piece
doesn't fall away.
I've used a carbide or diamond blade.

I've always used a router. Gives a nice clean cut and no "dust" to worry about. I do wear a resp and safety goggles. The guy who showed me how to cut with a router was a manufacturer of cultured marble tops and panels.

Re: Cutting A Cultured Marble Counter Top


Good new carbide blade will do the job. Cut the top being upside down. If there is a wall on one or both sides, backsplash will cover any imperfections, if not straighten it out with a wet sander, sanding sponges work best.

Good luck

Re: Cutting A Cultured Marble Counter Top


I stopped using cultured marble a few years ago (got sick of it!!) but I have done lots in the past. I always used a masonry blade either in a skill saw or grinder (smaller one). No chipping - pretty clean cut.

Re: Cutting A Cultured Marble Counter Top


does anyone have advise on 'polishing' surface abrasions? I set a paint can on the counter and it caused some scuffing.

Re: Cutting A Cultured Marble Counter Top


I had a builder call me today to see if I was interested in setting some vanity tops. So I checked it out and all of the tops will have to be trimmed to fit. the backsplashes are already built into the tops but the side splashes will also have to be trimmed to fit the profile of the backsplash.
Since only about 1/8" needs to come off the tops due to walls not square I'm thinking about trying to shave them with a belt sander.
is this a viable option to fit them to the wall. or would I be pissing in the wind trying to get 1/8th off with a beltsander?

forgot to mention that these are also cultured marble to the best of my knowledge

Exactly the same here. Cut from the backside starting from outer edges working in. I use my circular saw (sidewinder).

You can fine tune it with a grinder using a disc pad and 150 grit.

Re: Cutting A Cultured Marble Counter Top


When cutting its technique.masonry cutting blade is sufficient to cut through one inch or more. Using sawhorses to support your piece. Cut with shiny side down mark your cutting line on the rough side be sure to mark the back splash using a square to mark your line. With your lines marked it's.time to cut., now the technique part. Pull the safety guard back out of the way, cutting backwards starting at the back splash cutting upward till the saw cuts through the top line.then cut from the front of the top cutting backwards to the previous cut, be vary careful the saw will jump hard if you cut to fast. Do not cut like plywood.

Mike:
Put a 40 grit on your belt sander and it will grind off an 1/8" is short order with no chance of chipping. It's much easier to scribe with a belt sander than other tools.
