Acrylic and MMA Flooring Systems

Acrylic and MMA flooring systems cure in 45 to 60 minutes per coat because they harden by chemical polymerisation rather than by water or solvent evaporation. That is the property that decides most specifications: a floor can be recoated the same shift and returned to service the same day. This page covers the thirteen KAIDA PAINT® systems built on 100% reactive MMA acrylic resin, plus the one waterborne acrylic pavement system, and the one acrylic-cement terrazzo mortar. Builds run from a 0.3 mm sealer to a 9.5 mm terrazzo. The thickness table below is the fastest way to find your system; the acrylic-versus-epoxy table answers the question most specifications start with.

What is an MMA acrylic flooring system?

An MMA acrylic flooring system is a multi-coat resin floor based on methyl methacrylate monomer, cured with a peroxide initiator. Two consequences follow, and both matter more than any marketing claim.

First, the reaction is a free-radical polymerisation. It needs no water, no moisture from the slab and no ambient humidity, so the system cures at temperatures where epoxy stalls. Second, the material is 100% reactive. Nothing evaporates, so each coat reaches full film build and there is no shrinkage window to wait out.

Measured on the CrylForte systems: pot life is 10 to 20 minutes at 68 °F (20 °C), cure is 45 to 60 minutes per coat, and the service range runs from −40 °F to 212 °F (−40 °C to 100 °C).

How thick should the build be?

Thickness is the first decision, because it sets the duty the floor can carry. In this range the same resin family spans a 0.3 mm sealer and a 9.5 mm mortar.

Acrylic and MMA systems by nominal build thickness
Build	Nominal thickness	Sistema	Duty
Sealer / coating	12–50 mil (0.3–1.25 mm)	CrylForte™ Shield	Seals concrete, stops dusting, light traffic
Decorative broadcast	1/8–3/16 in (3–5 mm)	CrylForte™ Deco Quartz	Medium traffic, seamless colour
Self-levelling broadcast	3/16 in (4.75–4.8 mm)	CrylForte™ Deco Flake SL, Deco Quartz SL, SL	Medium to heavy traffic, washdown
Terrazzo mortar	3/8 in (9.5 mm)	CrylForte™ Terrazzo	Heavy traffic, abrasive wear, decorative aggregate

The 9.5 mm terrazzo is the only system in this range built on acrylic resin plus cement plus aggregate. That combination carries compressive strength above 4,600 psi to ASTM C579 and is the one to specify where the floor takes steel wheels or constant abrasive wear.

Acrylic or epoxy — which one belongs on your slab?

Both are two-component resin floors. They differ in what stops them working.

Where each chemistry is the correct specification
Condizione	MMA acrylic	Epossidico
Slab temperature at application	2 to 32 °C (35 to 90 °F)	Above 10 °C for a reliable cure
Return to service	45–60 min per coat; same-day handover	Typically 24 h before foot traffic
Moisture in the slab	Cures without slab moisture	Requires a dry slab or a moisture barrier
Odour during application	Strong monomer odour; plan ventilation	Low to moderate
Colour stability under UV	Holds colour	Aromatic grades amber
Cost per square metre	Higher material cost	Lower material cost

Where the slab is warm, dry and the programme allows a 24-hour cure, epoxy is the more economical specification. Where the slab is cold, the plant cannot shut for a day, or the floor sits under UV, the MMA acrylic range is the one that holds.

Which finish do you need?

Finish families across the thirteen systems
Finitura	Sistema	Where it is specified
Vinyl flake	Deco Flake, Deco Flake SL	Healthcare, retail, education — hides subfloor flaws
Coloured quartz	Deco Quartz, Deco Quartz SL	Food, pharma, heavy traffic — slip resistance built in
Terrazzo	Terrazzo	Heavy wear, decorative aggregate look
Solid colour	SL, Shield	Warehouses, factories, plant rooms
Stencil pattern	Concrete Stencil	External hardscape and demarcation
Tactile profile	Tactile Paving	Accessible routes, crossings, station platforms
Coloured pavement	Waterborne Polymer Pavement	Asphalt and concrete pavement, low odour

When the project rules out MMA

MMA monomer has a strong odour, and that single fact rules it out of some occupied buildings. Where the work happens beside patients, residents or trading space with no way to isolate the area, specify the waterborne polymer pavement system instead: water-based, zero odour, and rated for 5+ years of colour retention under UV. Where the area can be isolated and ventilated for a shift, the MMA systems remain the faster route.

Where the requirement is a floor above 9.5 mm, a trowelled mortar or a thermal-shock rating above 60 °C, the acrylic range is not the right specification. The cementitious urethane and epoxy ranges carry those duties.

What decides the system on site

Slab temperature at application. The MMA range works from 2 °C. Below that, the reaction slows and the recoat window stretches.
Concrete surface profile. A CSP 3 to 5 profile is what the bond figures are measured against — above 400 psi to concrete failure.
Ventilation and occupancy. This decides between MMA and waterborne, not between brands.
Moisture. MMA does not need slab moisture to cure, but standing water still has to go before the primer.
Traffic and chemistry. Fuels, oils, lactic acid and alkaline cleaners are the exposures these systems are tested against.

What to send us for a system recommendation

Area, and how many square metres per shift you can hand over.
Slab temperature range and whether the building is occupied.
Traffic type: foot, pallet truck, forklift, steel wheel.
Chemical exposure, named: fuels, oils, lactic acid, caustic cleaners.
Finish and colour direction, plus any slip rating the specification calls for.

Frequently asked questions

How fast can an acrylic floor take traffic?

45 to 60 minutes per coat at 68 °F (20 °C), so a three-coat system is walkable the same shift. Full chemical resistance develops over 7 days.

Can MMA acrylic be applied in a cold store?

Yes. The application window is 2 to 32 °C (35 to 90 °F), which is why these systems are specified where epoxy will not cure.

Does an acrylic floor need a topcoat?

Broadcast systems such as Deco Flake and Deco Quartz use a seal coat over the aggregate. Sealers and solid-colour systems are complete at the build thickness stated in the specification.

Is acrylic flooring the same as polyaspartic?

No. Polyaspartic is an aliphatic polyurea; MMA acrylic is a methacrylate monomer cured with peroxide. Both cure fast, but acrylic works at lower temperatures and carries a stronger odour.

How thick is a typical acrylic floor?

From 0.3 mm for a sealer to 9.5 mm for terrazzo mortar. Most industrial specifications land between 3 mm and 5 mm.

Will it hold colour outdoors?

The acrylic systems hold colour better than aromatic epoxy. For exposed pavement the waterborne polymer system is specified with a 5+ year colour retention rating.
