Ram-Board FAQ: Specifying Temporary Floor Protection Without the Guesswork

I am the quality and brand compliance manager at a construction materials supplier. I review every temporary surface protection order before it ships—roughly 250 SKUs a quarter. In 2024, I rejected about 18% of first deliveries due to thickness, moisture resistance, or labeling issues. This FAQ is the version I wish every contractor, GC, and facility buyer had before they specify ram-board.

What is ram-board, and where does it actually belong on a job site?

Ram-board is a temporary surface protection board used to keep finished floors, stairs, cabinets, and thresholds from getting scratched, dented, or covered in drywall mud during construction and renovation. It is not structural sheathing, not a subfloor, and not a permanent finish. The best use is in high-traffic paths: elevator lobbies, corridors, kitchen cabinet runs, and stair landings. In our Q1 2024 quality audit, most failures came from two places: unprotected thresholds and seams that were taped but not overlapped. If the board moves under foot traffic, it abrades the finish underneath. According to OSHA (osha.gov), walking-working surfaces must be kept clean and dry under 29 CFR 1910.22(a)(2), and a properly laid ram-board helps you keep temporary paths stable. Specify it by traffic level, moisture exposure, and surface sensitivity—not by price alone.

Why do I see single board computer 8gb ram, single board computer 32gb ram, canister purge valve, privacy screen protector, and how to block your number on a ram-board page?

Because search engines split words. Ram-board is a construction floor protection product. A single board computer 8gb ram and a single board computer 32gb ram are electronics. A canister purge valve is an automotive emissions part. A privacy screen protector is a device accessory. How to block your number is a telecom question. None of those are temporary surface protection. If you landed here for any of those searches, this page will not help. I would rather say that plainly than waste ten minutes of your time. If you are actually specifying floor protection, the rest of this FAQ is for you. If you need single board computer 8gb ram, single board computer 32gb ram, canister purge valve, privacy screen protector, or how to block your number, check a specialist source in that category.

What thickness and grade should I specify for ram-board?

Start with traffic and exposure. For light residential touch-ups, a 0.030 in. economy board can work. For commercial corridors, cabinet delivery, and repeated sub trades, I specify 0.040 in. heavy-duty board. Our standard heavy-duty roll is 38 in. x 100 ft, and it handles most corridor runs with 2 in. overlaps. Wet areas—tile prep, plumbing zones, exterior thresholds—need a poly-based or coated option because paper-based boards can swell at cut edges. In January 2025, heavy-duty ram-board rolls generally ran $90–$160 per 38 in. x 100 ft roll based on quotes we collected from three distributors; verify current pricing because resin and paper costs moved in 2024. I also require caliper readings every 500 linear feet. Thickness is not a suggestion when the finish underneath is a $12,000 hardwood install.

What is the biggest misconception about heavy-duty floor protection?

People think heavy-duty ram-board costs more because the material is thicker and heavier. Actually, the failure cost causes the specification, not the other way around. Vendors who can prove consistent thickness and moisture resistance can charge more because the alternative is rework. In one Q1 2024 project, a 0.030 in. board shifted at a terrazzo threshold. The board cost less than the heavy-duty option by about $1,200. The repair and schedule slip came to roughly $19,000. The assumption is that premium protection is the expensive choice. The reality is that cheap protection is expensive when it fails in a high-visibility area. I have rejected first deliveries that claimed to be within industry standard when the caliper reading was 0.033 in. against a 0.040 in. spec. Normal tolerance in our contracts is plus or minus 0.002 in. That is not a gray area.

Paper-based or poly-based ram-board: which one should I choose?

I went back and forth between paper-based and poly-based for two weeks on a multifamily turnover. Paper-based offered easier cutting, flatter lay, and better breathability over cured concrete. Poly-based had moisture resistance and wiped clean after drywall work. On paper, poly looked like the safer choice. My gut said use paper in dry interior corridors and save poly for wet zones and exterior thresholds. We split the order. The paper ran faster for the crew and taped cleaner. The poly held up at the plumbing rough-in. Ultimately, I chose not to pick one winner. That was the right call. A single-material specification would have either overpaid in dry areas or underprotected the wet ones. If your project is one open floor plate with mixed trades, consider a hybrid spec. At least, that has been my experience on occupied renovations.

What did your data and gut say about using a budget board?

The numbers said go with the 0.030 in. budget board. It was about 15% cheaper on a 60-roll order, and the spreadsheet showed a $1,400 saving. My gut said stick with 0.040 in. because the elevator threshold and cabinet delivery were going to see constant traffic. I went with my gut. Later, the site super sent photos of the budget board sample tearing at a steel door track. That small test saved us a full order. Every cost analysis pointed to the budget option. Something felt off about the edge crush and the way the roll relaxed after unrolling. Turns out that soft edge was a preview of tears at every turn. We still use budget boards for low-traffic closets. For main paths, I do not. If you are comparing two quotes, ask for a sample and walk it under a loaded dolly.

How should I inspect a ram-board delivery before accepting it?

I inspect four things before I sign: thickness, width, edge condition, and moisture response. Thickness gets checked with a caliper at three points per roll—start, middle, and end. Width is checked against the purchase order because a 36 in. roll will not cover a 38 in. spec without extra seams. Edge condition matters because crushed edges create gaps that catch debris. Moisture response matters because a paper-based board that swells at a cut edge will curl under foot traffic. In our Q1 2024 audit, we rejected maybe 17%—no, 18%, I would have to check the log—of first deliveries for at least one of those issues. Now every contract includes caliper and moisture requirements. If the vendor says the variance is within industry standard, ask which standard and get it in writing. That one sentence has saved us more rework than any discount.

What standards and current pricing should I verify for ram-board?

Use OSHA 29 CFR 1910.22 as a baseline for walking-working surfaces; the official source is osha.gov. For product specs, ask for thickness tolerance, roll dimensions, moisture absorption, and edge crush data. I also ask for a sample that matches the production run, not a lab sample. Pricing as of January 2025 was roughly $90–$160 per heavy-duty 38 in. x 100 ft roll based on distributor quotes we collected; verify current pricing because rates may have changed. Do not accept a verbal guarantee that a board will protect any surface without damage. No board does that. The goal is risk reduction, not magic. If you are still searching for single board computer 8gb ram, single board computer 32gb ram, canister purge valve, privacy screen protector, or how to block your number, this is the wrong product category. For construction floor protection, start with traffic, moisture, and finish sensitivity.
