Ram Board vs. Plywood vs. Cardboard: A Cost Controller’s Side-by-Side Comparison

Every time a project manager asks me about temporary floor protection, the conversation starts the same way: “Why should we pay for Ram Board when plywood and cardboard are cheaper?” It’s a fair question. I’ve spent six years managing purchasing for a commercial flooring contractor, and my job is to look at total cost, not sticker price.

This is a direct comparison between purpose-built surface protection boards—the ram-board category is the standard I use—and the usual improvised route: plywood, cardboard, or thin plastic sheeting. I’m not going to tell you that one product is always better. I’m going to walk through the numbers I tracked on a real 2,000-square-foot project and let you decide.

One thing before the math: OSHA’s Walking-Working Surfaces standard (29 CFR 1910.22, effective January 17, 2017) requires employers to keep walking surfaces clean and free of hazards. If your temporary protection is failing, you’re not just risking a repair bill; you’re creating a trip hazard. Verify current requirements at osha.gov.

What I’m comparing

Option A: Ram Board — a heavy-duty roll-out board made for temporary surface protection during construction and renovation.

Option B: The typical “cheap” route — 1/4-inch plywood, corrugated cardboard, or poly film. I’ll use plywood as the main alternative because it’s the most common choice.

I’m not comparing steel plates, fire-rated barriers, or systems for heavy demolition. I don’t know those products well enough to give credible advice. If you’re doing hot work or aggressive grinding, ask someone who does.

1. Upfront material cost

On paper, this is where plywood and cardboard are supposed to win. Our Q4 2024 purchase data from the Southeast showed the following delivered costs:

• 1/4-inch plywood: roughly $1.20 per square foot
• Heavy cardboard roll: $0.35 to $0.60 per square foot
• Ram Board: $0.45 to $0.55 per square foot by the half-pallet

Notice what happened there. The “premium” branded board was often cheaper than plywood. If I remember correctly, the plywood quote included a delivery fee and a minimum-order charge. Ram Board came on a pallet with lower freight. That flips the usual assumption.

Verdict: By delivered material cost alone, Ram Board can beat plywood and is competitive with cardboard.

2. Install and removal labor

Last year, I compared two 2,000-square-foot polished concrete projects. The crew was the same size: two people. With plywood, we planned for cutting, fitting, taping seams, and sweeping up sawdust. It took about six hours. With Ram Board, the same crew unrolled the boards, taped the seams, and finished in about three and a half hours.

I want to say the Ram Board installation took four hours—no, wait, it was closer to five when you count the cuts around columns and a trip back for extra tape. Either way, it was noticeably faster than plywood.

Removal is where the gap gets bigger. Plywood often has tape residue stuck to the grain. Cardboard tears and leaves fibers behind. Ram Board comes up in large pieces when you pull slowly, and the tape tends to stay on the board. We still wiped the floor, but we didn’t need adhesive remover.

Had a job where the owner gave us 48 hours to protect a new walnut floor before movers arrived. Normally I would test our method on a sample area first. There was no time. We went with Ram Board because we knew our crew could install it quickly and remove it without residue. In hindsight, I should have done a test patch anyway—but the deadline made that impossible.

Take this with a grain of salt: labor rates vary by market. At $45 per hour fully burdened, the labor difference was roughly $450 on that one project. That alone can outweigh any material price difference.

Verdict: Purpose-built boards saved us 30 to 40 percent of install and removal labor in most occupied-space projects.

3. Risk and repair costs

When I pulled our check register from last year, I found two repair line items that traced directly to inadequate floor protection: $1,400 to repair a scratched porcelain tile and $900 to repaint a wall base after cardboard left brown stains. Neither was a surprise to anyone who had walked the job site.

Plywood is strong, but it is not a surface protector. It can have splinters, warped edges, and exposed nail heads. If you slide a sheet instead of lifting it, it can scratch the finish underneath. Cardboard absorbs moisture and can bond to fresh paint or adhesive. Poly film slides and becomes a trip hazard.

I’m not saying improvised protection is always wrong. It has a place on rough, unoccupied surfaces. But when you put a “temporary” product over an expensive finished floor, you are betting the repair cost against the material savings.

On that note, use the right product for the task. Sprayway glass cleaner is a glass cleaner, not an adhesive remover. It will not fix the mess from a failed protective layer. That’s a small example of a bigger buying principle: know the boundary of every product you specify.

Verdict: Risk-weighted cost favors a board designed for the job. One failed project can erase years of “savings” from cheap materials.

4. Don’t over-buy: right-size the protection

Here’s a counterintuitive conclusion: buying more protection than you need is also a mistake. I once reviewed a request for a single board computer with 32GB RAM for a simple job-site logging system. The engineer wanted headroom. After we measured the actual data rate, a single board computer with 8GB RAM did everything we needed at half the hardware cost and lower power draw. Same logic applies to floor protection.

For heavy demolition or abrasive grinding, a fiberboard product like Ram Board is not my first choice. That’s not an insult; it’s a boundary. I would rather send the crew to a specialist who handles those conditions than pretend a general product can do everything.

Buying the most expensive protection “just to be safe” is the same failure as buying the cheapest. You need a specification: traffic level, wheel weight, duration, surface type, and exit conditions. Then compare products against those specs.

Verdict: Right-sized protection is cheaper than over-protection and safer than under-protection. That sounds obvious, but the invoices show most buyers skip the sizing step.

5. The total-cost checklist I use

Here is the exact set of fields in my procurement spreadsheet. I use it for floor protection, and I use it for other job-site purchases—Can Am Defender doors, Sprayway glass cleaner, and even single board computers. The product changes; the math doesn’t.

• Delivered material cost per square foot
• Install labor (hours × burdened rate)
• Removal and disposal labor
• Tape, adhesive, and consumables
• Repair risk (probability × average repair cost)
• Reusability on the next job

If you compare only the first line, you are making a decision with maybe one-third of the information.

So: Ram Board or the cheap route?

Use the cheap route if:

• You have one light-traffic day and the floor finish doesn’t matter.
• You already own the plywood and labor is free.
• You are covering a floor you plan to replace anyway.

Use Ram Board or a similar purpose-built board if:

• You are protecting a finished floor you will have to fix if damaged.
• You need fast installation and clean removal.
• You are comparing total cost, not sticker price.

And before you believe any claim that one product is perfect for every situation, ask your supplier what the product is not for. The best vendors I’ve worked with—including the one that distributes Ram Board—are honest about their limits. That honesty is worth more than any product spec.

This worked for us, but we are a commercial contractor with predictable schedules. If you are a residential painter doing one room, the calculus might be different. And this pricing was accurate as of Q4 2024. Verify current quotes before you budget.

The cheapest temporary floor protection is not the one with the lowest price per square foot. It is the one with the lowest total cost per successful project. That’s the comparison that matters.
