cutting cultered marble vanity top
How do you trim a cultured marble vanity top? Customer chose this top but needs to be trimed a total of 3/4 off one end. This is the type with the core poured with some unknown substance with a Gel coat on top. The cut end will be hidden with a sidesplash, so I’m not too concerned about the quality of the cut. Can I cut it with a circ saw? or would a portable planer be workable? Thanks

Circ. saw works great..... abrasive blade. Put a few runners of masking tape down to keep from marring the gel coat.
My C. Marble shop tells me they drag the saw backwards, but I go slow fwd. with no problems.
It cuts like butter with a right angle grinder with a thin abrasive cut off disc.Two hands on it for control.Use a grease pencil to mark it and do it outside with goggles and face mask.You'll need to back cut to finnish the cove corner.maybe do a practice run taking just a 1/4 " off first
and wear a mask.

tape the topsde where the cut is to be and cut from the backsie with yur cicular saw...
use an abrasive masonry blade...

Grinder with metal cutting thin disc close to the line from the top. Sand with coarse belt to line for a nice finish. Support the cutoff. You bet, big dust.

Thanks everyone, looks like I know how to proceed
What IMERC said.
Tape the front, cut from the back --- circular saw w/ abrasive blade.
Make sure blade is set up square to saw foot - goofy things happen at the counter / backspalsh intersection of the casting if blade is not square.
Blade cutting action "enters" through the gel coat layer and pulls through the material.
This is the same principle as the back cutting operation which someone else posted ".....dragging the saw backwards ....." but this is a whole lot easier to control.
Very dusty operation - outside, goggles & mask.
JimNever underestimate the value of a sharp pencil or good light.
diamond blades are good here too....

Saw dust
I have always used a regular circular saw blade and cut from the bottom.
I use a belt sander to shape to the wall and to back bevel.

regular blades seem to chip more....
and a chip in the wrong place could be diastorous....

You're probably right. I've never used anything else. I'll try a diamond abrasive blade next time.
I cut a solid surface top a couple of months ago and that was sweet. Still dusty but a nicer texture material than cultured marble.
We had a 6" x 1/2' band under the sink that we cut with the miter saw. It cut nice.
Rich
you'll still have the dust but there is no sense in tempting fate....
use to cut them like you do...
no more...

I've always just used a regular carbide tip blade ...
more teeth the better ... shoot for 40 on the circular saw.
I'll buy what ever is the cheapest ... cheap but brand new blade has never let me down ... then ... like U said ... beltsand into place if it's anywhere near exposed.
never had a chip problem.
used to sub for a bath dealer ... coupla years ago it was nothing to cut between 5 and 10 a week. I'd use the same blade for 2 or 3 tops ... then they'd go to the bottom of the stack for demo.

I've always used a regular blade because I didn't know any better. And I never had a chip problem.
Most modifing I have had to do is with a belt sander to fit a crooked wall.
I'll give an abrasive blade a try. I've been wrong before. Maybe I'll like it better.

Same here. It wasn't unusual to do two kitchens and 4 baths a week for a company in Philly..condos and tract garbage , but it paid well.Spheramid Enterprises Architectural Woodworks
