No worries
Pleasure to help
Depending on the marble, (lighter ones)many marbles as the guys said can be polished after 400 grit.
With quality diamonds, quality polishing compounds and proper
techniques you can get very good results. Darker marbles and hard to polish marbles should be honed higher. While you can get an good results polishing after 400,polishing after higher grits will generally give you better results and produce a harder and longer lasting polish.
However not a difference most clients could see visibly.

Robert,

We use several different compounds and look at each like a tool in the toolbox. Sometimes MB22 (slower acidic reaction) and other times International Stoneworks Marbrofin X (extremely aggressive) or maybe something in between. We have used 5X, Diaglow among others. The key for us is to be sure to grind well with quality diamonds.

With a polishing compound? Sorry for the questions but the company I worked for prior and the way I've been doing things is always finishing at a 1500 grit then polish. I've seen crystalizing done after 400, what are you using to polish?

Thanks Stuart. 

I agree, just going to give them the option for a full restore, we don't do quick fixed and our reputation is built on our quality and Workmanship. 

I'm confused with what you guys mean by 400 grit straight to polishing. With kp85 or 92 I've never gone to polish from a 400 grit. I always go up to at least 1500. You're saying I can get a clear polish right from 400?

That's a big floor to have to handle when your used to small residential jobs. It would also be a good job for you to book and complete.
I would like to add a few things for you.
Don't forget about servicing your other clients-I usually let large jobs know (in writing) we may need to pull crews to service other accounts.
Pricing and scope of jobs (relating to quality) will vary from area to area.
Toronto pricing and quality standards are good in your area so you should be able to price this job well.
I think you should not even offer your option A where you are giving them a marginal Job.
Be a five star company and give them a high quality job with predictable results. (keep in mind-many people will see your work)
Do the repairs properly ,find a starting point that will remove all abrasion and etches from the floor.
Our baseline starting point is usually at 220 grit resins, then up to a point(400 or higher) so we can produce a high polish with excellent clarity.
You must be able to remove or polish out picture frames as well along with keeping the grout lines clean and free of any discoloring caused by slurry.
If the grout lines were soiled to begin you need to deliver them fully cleaned.
How many repairs are involved will affect your pricing as well.
Doing the Job correctly with swing machines (planetary machines will be more efficient) using 2 crews could take up to 15 days.
If you want to price the job at a $1000 per crew per day you could be at $4.50 SF which may be in the ballpark.
Talk to your contact and find out what they are looking to do. Companies have a budget for this and they also usually know exactly what they want.(quality wise)
As far as tooling and compounds-quality resin diamonds  and a polishing compound your comfortable with is important.
There are a boatload of products to chose from-Get some samples and see what works best for you and your techs.
KP85 is slow-KP92 is faster if you want to stick with Klindex products.

Try a 200 resin,400 resin, polish and bid $2.00 or 2.50 per sqft good luck.

Clean, polish and fill cracks and holes but not level them flush with the floor. Sealed with clear penetrating sealer. 

B) A full restore and make the floor look brand new again. Resurfacing to a high polish finish. Cracks and holes and ground flush with the floor and of course sealed with clear penetrating sealer. 

Oddly enough I learned this trade from Dana with the monkey pad system. I love the pads for honed and patina finishes but I can't figure out how to get a clear polish finish with the pucks and 11000 pad system. I have a klindex machine that wright's about 150 lbs without weights. 

The polishing compound is KP85 made by klindex. It's a bit of a pain to work with but I love the results. 

Pricing. I never ever do square footage pricing but for an area this big I need to justify throwing costs. I was thinking $2.00 a square for option a. $13,400 total. 
$3.50 a square foot for option b. $23,450 total. I know not every foot would have to be ground so I was thinking $3.00 a square foot but then I'm thinking why only a $1.00 more for a full grind. Clearly over thinking thus lol. 

I'm assuming it would take 4-5 days for option a, 7-8 days for option b. That's a complete guess. I never restored this much marble at once before. I like to gross $1000 a day on residential job but think I should make more on a larger commercial job.

Any input would be nice. I'm not going to crystalize.

Hi guys, new member here. I appreciate all the knowledge! 

We usually do small residential job or commercial, nothing ever close to this size. 6700 square feet of limestone at the Mandarin head office and flagship banquet hall. 

I've attached some pictures. Various cracks some hairline, others a bit larger. Traffic areas will need a grind. At least 800 grit, however there's a some deep stains and etches scattered in the lobby and hallways. Bride and Groom rooms have bathrooms that are destroyed. 

I know I'm competing against the company who did the work 9 years ago. They're a franchise and much bigger than my company. I already know my price will be more so I tried to sell them on out workmanship. 

There will be three hopefully four working. Two machines, two vacuums. 

I have prepared two options.

A) Clean, polish and fill cracks and holes but not level them flush with the floor. Sealed with clear penetrating sealer. 

B) A full restore and make the floor look brand new again. Resurfacing to a high polish finish. Cracks and holes and ground flush with the floor and of course sealed with clear penetrating sealer.
