10-Year TCO: Epoxy vs Cementitious Urethane vs MMA

A flooring total cost of ownership comparison over ten years usually reverses the order of the quotation. The cheapest installed floor is rarely the cheapest floor, because the expensive part is not the resin but the days the line is stopped.

Three systems are compared here: a 1 mm epoxy, a 6 mm cementitious urethane and a 3 mm MMA. All three are legitimate choices, and the arithmetic that separates them is short enough to do on one page.

The numbers below are planning ranges for a European or Middle Eastern plant in 2026. Replace them with your own quotation and your own margin, and the conclusion usually holds.

Why ten years, and not five

A flooring total cost of ownership view also forces the owner to name the horizon before arguing about products. A five-year window flatters a thin system, because the first recoat falls just outside it. A ten-year window catches one full recoat interval and usually one repair cycle, and that is where the difference appears.

Ten years is also the horizon most plants use for a capital plan, which makes the output usable rather than academic. A floor lifecycle cost that runs past the planning horizon tends to be ignored in favour of the installation price.

The comparison should include everything the owner pays: installation, maintenance, maintenance labour, lost production and the value left at the end. Anything left out tends to favour the cheapest bid.

It should exclude anything the owner does not pay, such as the contractor’s mobilisation margin or a supplier’s marketing. A plant that has never run the arithmetic usually assumes the thick system is the expensive one, and the assumption survives until somebody puts the five lines on one page. A TCO resin floor that includes those is a sales document rather than a decision tool. The exercise takes an afternoon and it changes the conversation from price to cost, which is the only conversation a capital committee listens to.

Line 1: installation

Every line in a flooring total cost of ownership has to be quoted in the same units, or the table becomes a work of fiction. Installation for a 1 mm epoxy lands around 55 to 75 USD per square metre in a food plant, including preparation. The same area in a 6 mm cementitious urethane lands around 100 to 140, and a 3 mm MMA around 85 to 115.

Those ranges assume a slab that needs grinding rather than planing. Where the substrate is contaminated or broken, preparation can add 20 to 40 per square metre to any of the three, and it is the line most often omitted from a first comparison.

A floor replacement cost in year eight is not simply the year-one price inflated. Removal, disposal and reinstatement add 30 to 50 percent, and the plant pays it while the line is stopped, which is the subject of the next line.

For the TCO resin floor, installation is therefore the smallest of the five lines in most plants. The practical consequence is that a flooring total cost of ownership discussion should start with the quotation and then leave it quickly. It is also the only one that is visible on a quotation, which is why it dominates the conversation.

Line 2: downtime, the line that decides

Downtime cost usually exceeds installation cost in a plant running more than one shift. The downtime cost is also the line most sensitive to the plant’s own schedule, which is why two identical buildings can produce different answers. A line producing 8,000 units an hour at a 12 percent margin loses roughly 9,600 USD of margin per hour of stoppage, before labour and waste.

A two-day shutdown therefore costs more than the floor. That single fact explains why fast-cure systems sell at a premium and why the the lost margin belongs in the first column of any comparison rather than the last.

The comparison has to count closures, not days. A system that needs two closures of three days is worse than one that needs one closure of five, even though the total days are similar.

Where a plant can phase the work, the downtime cost falls sharply och the ranking can change. A plant that can work in bays should model three closures of two days rather than one of six, because the margin lost per closure is not linear. That is why the same three systems produce different answers in a plant that can work in bays and one that cannot.

Line 3: upkeep and recoat

Figure 1: Every closure is a line in the table, and usually the largest one.

Maintenance is the line owners underestimate most often, because it is spread over years and paid from a different budget. A 1 mm epoxy in a wet area typically needs a recoat interval of five to seven years, and a heavy washdown room may need four.

A 6 mm cementitious urethane typically runs ten to fifteen years before a full recoat, with local repairs in between. A 3 mm MMA sits between the two, at seven to ten years in a moderate duty room.

A recoat interval is not only material. It is preparation, primer, broadcast and a closure, and the closure is usually the largest component. That is why a cheap recoat every four years can cost more than an expensive floor every twelve.

Keep a maintenance record per room, with dates and areas. The record also shows whether a recoat was needed earlier than expected, which is the first sign that the original assumption was wrong. Without it, the next comparison starts from memory, and memory favours whichever system is currently installed.

Line 4: patch and repair allowance

The floor replacement cost assumption also drives this line: a floor that will be replaced in year nine needs a different repair policy from one expected to last fifteen years. Every floor gets damaged, and the difference between systems is how much of the damage can be repaired without a closure. A thin system is easy to patch and hard to make invisible; a thick one takes longer and looks better afterwards. A thin epoxy patch is quick but visible; a thick urethane repair needs a formed detail and a longer window.

Where the plant has a floor lifecycle cost history, use its own repair frequency instead of the default, because the default is only a starting point. Allow one repair event per 500 square metres per five years in a wet process room, and price it at the contractor’s day rate plus material. That allowance is small per square metre and large per event, which is exactly why it gets forgotten.

The floor lifecycle cost should also include the cost of not repairing, which is a food safety finding. That cost is harder to quantify, and it is usually the argument that moves a capital committee.

Where a plant keeps a drum of the specified system and a method statement, the repair cost falls by half. A plant that holds a drum, a method statement and a name is a plant that repairs a defect in a shift rather than in a quarter. That is an upkeep decision rather than a materials decision, and it is cheap to make at handover.

Line 5: residual value at year ten

Residual value is the part of the comparison most often left out and the one that separates a ten-year floor from a five-year one. A 6 mm urethane with eight years of life left has a real residual value to the next owner of the building.

A 1 mm epoxy at year ten is usually at the end of its life and carries no value at all, which means the full replacement cost falls inside the next planning period.

For an owner-occupier, the value left shows up as deferred capital rather than as cash. For a landlord or a tenant with a dilapidations clause, it shows up as money, and the floor replacement cost becomes a negotiating position rather than a forecast.

Treat the value left conservatively: count remaining life in years, multiply by the annualised installation cost, and do not add anything for condition beyond that. The number also gives a landlord a way to argue about dilapidations without commissioning a survey. It is a planning number, not an asset valuation.

Discounting, and why 6 percent is enough

A discount rate converts future spending into today’s money, and it matters because the three systems spend at different times. At 6 percent, a cost in year eight is worth about two thirds of the same cost today.

Six percent is a reasonable planning rate for an industrial owner: above inflation, below the cost of capital for most food businesses. Using zero percent overstates future costs, and using 15 percent makes every future cost disappear.

The discount rate should be stated in the document, because a comparison without one cannot be checked. Two analysts using 6 and 12 percent will reach different conclusions from identical data.

Where a plant has a published hurdle rate, use it and say so. The same discipline applies to the downtime figure: state it, and let somebody challenge it. A TCO resin floor that uses the company’s own rate is harder to argue with than one that uses an industry average.

The table, and what it says

For a first pass, the flooring total cost of ownership only needs to be accurate enough to rank the three options, not to predict the future. Run the five lines per square metre over ten years at 6 percent, and the ranking usually comes out as cementitious urethane first in wet process rooms, MMA first where closures dominate, and epoxy first in dry areas.

That is not a product preference, it is arithmetic. Each system wins in the room where its weakness is not exercised, and the TCO resin floor is really a map of which weakness each room exercises.

The downtime cost assumption is the one to test first. Halve it and the ranking moves towards the cheaper installation; double it and the ranking moves towards the fastest cure.

Write the assumptions at the top of the table, including the discount rate and the downtime figure. The last step is to run it twice with different downtime assumptions and see whether the ranking holds. A comparison that can be re-run by somebody else is a comparison that survives a capital review.

Frequently asked questions

Is a ten-year comparison better than five?

Yes, because a five-year window flatters a thin system by ending before its first recoat. Ten years catches one recoat and one repair cycle, which is where the systems actually differ. If the horizon is shorter than the life of the cheapest option, the comparison is really a cash-flow exercise rather than a flooring total cost of ownership one.

What is the biggest line in a floor TCO?

Downtime in most plants running more than one shift. A two-day closure on a high-volume line can exceed the entire installation cost, which is why fast-cure systems carry a premium. That premium is small against the margin lost in a single extra shift, which is why the arithmetic so often surprises the plant that runs it.

Why discount at all?

Because the three systems spend money at different times. At 6 percent a cost in year eight is worth about two thirds of the same cost today, and ignoring that overstates future spending. State the rate, and the flooring total cost of ownership becomes reproducible by anyone who reads it. A rate that is never written down is a rate that gets changed after the decision.

How often does a 1 mm epoxy need recoating?

Every five to seven years in a wet area, and every four in a heavy washdown room. Cementitious urethane at that thickness assumes 70 °C washdown twice a day, and hotter service halves that figure. The number that matters is not the recoat year but the year the room has to close for it.

Should residual value be included?

Yes, conservatively. A floor with eight years of life left at year ten has real value to the next owner, and a thin floor at the end of its life means the replacement falls into the next planning period. That is a budget problem rather than a technical one, and it is the argument that usually convinces a finance director.

What downtime figure should I use?

Your own line margin per hour, multiplied by the hours of closure, then discounted. Use closures rather than days, because two closures of three days cost more than one of five. In a phased plant the closure figure falls, and the ranking moves towards the cheaper installation.

Does the ranking change with plant type?

Yes. In dry areas the epoxy usually wins, in wet process rooms the urethane usually wins, and where closures dominate the MMA often wins. The comparison is really a map of which weakness each room exercises.

Why food plants work with Kaida Paint

Kaida Paint supplies all three systems, so the flooring total cost of ownership comparison is not a product argument for us. Send the room schedule, the line margin and the closures you can accept, and we will return the five lines per square metre with the downtime cost stated separately. If the answer is that a cheaper system wins in a dry store, we will say so and quote that instead.
