Ordering MSI Montauk Black Slate: A 6-Step Procurement Checklist

When I took over purchasing for our design-build company in 2022, I assumed natural stone orders worked like any other material order. Pick a product, get a quote, place it, done. Two years and roughly 70 surface-material orders later—give or take—I can tell you it's not that simple.

This checklist is for designers, contractors, and anyone managing a renovation who's about to order slate, stone tile, or countertop material—from MSI International Surfaces or any other major supplier. Six steps I wish someone had handed me on day one: verify samples, match the finish to the application, lock in delivery, confirm batch consistency, build in waste, and prep the site.

Step 1: Get a physical sample before you commit

Product photos are inspiration, not specification. The MSI Montauk Black slate looks uniform and dark online. In person, you'll see natural variation—charcoal undertones, occasional mineral veining, sometimes a hint of bronze depending on the lot. That variation is part of the appeal, but only if you know about it before the material shows up.

In 2023, I was specifying a kitchen with white kitchen cabinets. The design called for a dark countertop to ground all that bright cabinetry. I almost submitted the order based on the website photo. The physical sample saved me: the slab had warm undertones that clashed with the client's oak flooring. The photo never showed that.

If you're ordering samples remotely, the shipping cost adds up—USPS raised First-Class postage to $0.73 in January 2025, and freight rates keep drifting upward. The sample is a few dollars. The wrong-slab redo is thousands. Request a physical sample per product and check it against your actual cabinet finish and flooring, not your monitor.

Step 2: Match the finish to the application

Montauk Black slate works on floors, countertops, and feature walls. The finish changes how it behaves. Honed slate resists water spotting—a smart pick for showers. Tumbled finish adds texture and hides scuffs in mudrooms. Polished slate looks striking but shows scratches in high-traffic areas.

I remember a project where the designer insisted on polished slate in a ground-floor entry. Every winter boot tracked in fine gravel. Within months, the finish looked worn. The look was right for the portfolio, but not the entryway.

Before you quote a stone to a client, ask how the space will be used. The right finish for a powder room isn't always the right finish for a mudroom.

Step 3: Lock the delivery window in writing—and be willing to pay for certainty

Here's where I have a clear opinion: in an emergency, delivery certainty is worth the premium. The fee buys predictability, not just speed. Put another way: you're paying to take the word "probably" off the table.

In March 2024, we paid $400 extra for rush delivery on a slate order. I want to say it was exactly $400—I'd have to check the invoice, but that's the right ballpark. The alternative was missing a $15,000 event for a client who refers our work. That $400 was cheap insurance, and it paid for itself the day the stone arrived on schedule.

The hard way: I once accepted a "probably about two weeks" delivery promise to save $90 in freight. Every calculation said save the money. My gut said the timeline felt optimistic. I didn't listen. The stone showed up on day 19, the installer had already been rescheduled, the delay rippled into two other jobs, and the $90 savings cost us over $800 in labor and rescheduling. In my opinion, that's the most expensive kind of discount you can take.

Step 4: Confirm batch consistency before you approve the order

This is the step most first-time buyers skip. Natural stone comes out of the ground in batches, and variation between batches is real. MSI is generally reliable about coordinating lots—but "generally reliable" is not "guaranteed identical."

In my first year, I approved a 200-square-foot Montauk Black slate floor order without asking about batch coordination. When the pallets arrived, the tiles came from two different production runs. The color difference was subtle in individual tiles; across the whole floor, it read as a checkerboard in certain light. We lived with it. The client didn't complain out loud, but it wasn't what we had pitched.

The fix takes five minutes: ask your sales rep to confirm the order ships from one coordinated lot. If the order is large, request photos of the actual material. It costs nothing and eliminates the most common surprise in natural stone.

Step 5: Order extra for waste, breakage, and the missing corner tile

Stone tiles crack in transit. Layouts demand cuts. The one piece you need to finish a floor is always the piece you didn't order.

The standard allowance is 10% for a grid layout, 15% for diagonal or herringbone patterns. This isn't budget padding—it's a reorder cushion. In 2023, a single spare box of slate saved us a three-week wait for one missing corner tile. Keep the leftover boxes on the job site until the punch list is done.

Step 6: Protect the site—and the crew's shirts

The installation is where perfectly good plans meet reality. Before the crew arrives: tape off adjacent surfaces, lay down ram board, and make sure the workspace is clean and dry.

A note on the mess factor: painters and installers will get paint on their clothes. You'd think after years in this business I'd have a better system than hoping it doesn't happen. The most frustrating part of install day is watching someone scrub a stain that's been drying for an hour.

So, the practical answer to how to get paint out of clothes: act while it's wet. Rubbing alcohol lifts most latex paints; acetone handles tougher spots. Wait until it dries and your odds drop sharply. Add a tube of hand cleaner and a pack of shop towels to the job site supply list and you've saved yourself a dozen headaches.

While we're on the subject of garage and mudroom projects: clients sometimes ask about garage floor epoxy as if it's the same category as stone tile. It isn't. Epoxy is a coating applied over concrete; stone tile is a product you lay. The procurement checklist is the same either way—sample first, confirm the batch, lock the delivery date—just don't assume they behave the same.

Pitfalls that cost more than they save

• Verbal promises are worth nothing if they're not on the purchase order. I don't care how long you've worked with a supplier. Write it down.
• "Zero maintenance" stone isn't a thing. Natural stone needs sealing, regular cleaning, and occasional re-sealing. Per FTC advertising guidelines (ftc.gov), product claims must be truthful and substantiated. When a supplier says "never needs maintenance," ask them to put it in writing—and explain what it means.
• Don't quote a specialty stone without checking availability. Some products have 4–6 week lead times. You don't want to discover that after you've promised a client a 12-day turnaround.

There's a genuine satisfaction in a clean order: samples verified, delivery locked, batches confirmed, extras on site. After the early chaos, the process is what keeps projects moving. Being able to tell a client "yes, it's coming, here's the date"—that predictability is worth more than any discount.
