I manage purchasing for a 40-person commercial construction firm. It’s not the most glamorous job, but it keeps the office and the field running. In 2024 I placed about 240 orders across 15 vendors—everything from Mapei products and fall-protection gear to printer toner. I report to both operations and finance, which means I get asked why things cost money and why they weren’t cheaper.
So when a project manager emailed: “Need Mapei adhesive type 1, please order,” I didn’t blink. I knew Mapei made tile adhesives. I had bought Mapei products before. I typed the phrase into our supplier portal and got a long list. That’s when the blinking happened.
The surface problem: one word, a hundred meanings
“Mapei adhesive type 1” sounds specific. It isn’t. It’s a category—or more precisely, a performance reference. Mapei makes multiple adhesive products that can meet a Type 1 classification. Are we bonding porcelain, glass, or natural stone? Interior or exterior? Concrete substrate or cement board? What’s the schedule? All of this changes which Mapei product belongs on the order. The PM thought he gave me a clear instruction. I thought I needed to fill a purchase order. Neither of us thought about the actual installation.
“Coatings paint” is the same red flag
I hear “coatings paint” at least once a quarter. It’s a catchall phrase, but coatings and paint are not interchangeable. A coating is engineered for protection—moisture, chemicals, abrasion. Paint is a decorative film with limits. If you order paint where a coating is required, you find out about six months later, with the failure already in the rearview mirror.
I’ve also learned to ask for data sheets before trusting claim labels. Per FTC guidelines (ftc.gov), environmental claims like “low-VOC” have to be substantiated—and a data sheet counts. We once chose a “coatings paint” because the can said “eco-friendly.” The supplier’s data sheet showed it wasn’t rated for the moisture conditions in the spec. That single question saved us a $6,000 redo. (Should mention: the product was fine for its intended use; it was us who almost misused it.)
The deeper problem: we buy nouns, not jobs
The first few times, I blamed the person sending the request. Why can’t they just write the product number? But the deeper issue is structural. Our purchasing vocabulary runs on nouns: adhesive, sealant, coating, paint. The actual job is a verb: bond, seal, protect, block. Once you drop the verb, you lose the job. “Adhesive” doesn’t tell anyone what is being bonded, to what, or under what conditions. It’s like saying “I need a vehicle” when you’re running a 300-mile highway route. A motorcycle works technically—until it doesn’t.
That’s why “adhesive balloon party” isn’t just a bad search string to me anymore. Someone doesn’t want “adhesive.” They want something that sticks latex to a wall without popping the balloon or damaging the paint. That is a completely different specification than Mapei adhesive type 1. I ordered the wrong thing for a party request once. Actually, the wrong thing was me being lazy—I picked a spray adhesive designed for upholstery. The balloons didn’t stick; the tape I used instead worked better. The lesson wasn’t about the product. It was about asking the right question before ordering.
What vague requests actually cost
The “just Type 1” order ended up costing more than the product. Direct material? $740. That was bad, but the bigger hit was labor and schedule. The crew installed porcelain tile with the wrong Mapei product—or more accurately, with a Mapei product that wasn’t the right one for that stone and substrate. By the next morning, the setting material hadn’t cured as expected. Tiles moved. We chipped out 800 square feet, reordered the correct Mapei system, and lost a day. I don’t remember the exact labor number—I want to say around $1,900—but the point stands.
Then there’s the trust cost. The project manager didn’t blame the product or the spec ambiguity. He looked at me. When I said, “But you wrote Type 1,” he heard me passing the buck. Even if I was technically right, I was effectively wrong. The vendor who couldn’t provide proper invoicing cost us $2,400 in rejected expenses; the vendor who delivered late made me look bad. But the most expensive mistake was the one where I filled in the blank myself.
It wasn’t the product that failed. It was the specification that was never shared.
When to say “this isn’t my lane”
Which brings me to another question that shows up in our internal chat now and then: “Can adults get sealants on teeth?” I order construction sealants, so I understand the confusion. The answer is yes—adults can get dental sealants. But I’m not the person to explain the procedure. Same with the adhesive balloon party question. There’s a vendor for that, and it’s not the same vendor who supplies Mapei tile systems.
I used to think saying “I don’t know” made me look weak. Now I think the opposite. The vendor who told me, “This isn’t our strength—here’s who does it better,” earned my trust for everything else. Specialists who know their limits are more reliable than generalists who overpromise. The same goes for buyers. I don’t need to know every chemistry. I need to know where to find the answer.
The fix: three questions before any product order
We changed our process after that job. Now any request for an adhesive, sealant, coating paint, or similar material has to answer three questions:
- What is being bonded, sealed, or coated—specifically?
- What are the substrate and environment conditions?
- What is the manufacturer’s product data sheet, or who on their technical team can confirm?
If a request can’t answer those, we stop and send it back. Sometimes we call Mapei’s technical support or the local rep; they can confirm within minutes. This isn’t bureaucratic. It’s about not making my colleagues and the crew pay for my assumptions.
That doesn’t mean every order needs a full spec review. If I’m buying a tube of Mapei sealant for a small repair, I’ll order the standard one from the shelf. But if failure causes rework, waterproofing issues, or safety hazards, we take the extra five minutes.
The real lesson isn’t “adhesive is a bad word.” The lesson is that the word doesn’t carry the job. Mapei’s product lineup is broad and, as of February 2025, still evolving. “Excellent” means nothing if we order the wrong product based on a vague category. Ask the questions. Verify the spec. Respect your boundaries—and the supplier’s expertise. That’s how you save more time than any “quick order” ever will.
