About Sika Sikafloor MultiDur ET-05 HSR AP

Sikafloor MultiDur ET-05 HSR AP is Sika’s answer to a common industrial problem: floors that need to be tough and easy to clean, but that turn treacherous the moment water, oil or process liquids reach them. It is a two-part epoxy system, not a single product in a tin. A Sikafloor-264/264 HC primer wets out and seals the concrete, and a second coat of the same resin, thickened with 2 to 3 percent Sika Extender T and loaded with roughly 10 percent quartz sand at 0.4 to 0.7 mm, builds the working surface. That sand is what gives the floor its deliberate, gritty texture, so grip is engineered into the profile rather than sprayed on afterwards. Laid at 0.7 to 1.5 mm and finished in a wide range of RAL shades, it reads as a proper coloured floor, not a raw industrial screed.

For engineers and contractors in India, the appeal is that one specification covers three demanding settings at once. Car park ramps and decks need a surface that will not glaze under tyres and stays safe when wet. Maintenance hangars deal with oil and hydraulic spills. Beverage, dairy and food plants need a floor that shrugs off constant washdown and can be scrubbed clean. ET-05 HSR AP is positioned squarely at all three. As Sika’s authorised distributor and applicator across Delhi NCR and Pan-India, Space Arc Engineering supplies the full system and can carry out or supervise the substrate preparation and application, which is where anti-slip epoxy floors are usually won or lost.

The technical insight

The performance of this floor comes from separating two jobs that a single smooth coating cannot do well together: bonding and grip. The Sikafloor-264 epoxy binder does the heavy chemical work. It cures into a rigid, dense matrix that reaches about 53 N/mm2 in compression and 20 N/mm2 in flexure, with a Shore D hardness near 76 and abrasion loss of only about 41 mg on the Taber test. That hardness is exactly why a plain epoxy this strong would be dangerously slick when wet. The fix is mechanical, not chemical. Broadcasting and mixing 0.4 to 0.7 mm quartz sand into the topping raises thousands of fine peaks across the surface, so contact happens on grit rather than on a polished film, and a boot or tyre keeps traction even under a film of water or oil. Sika Extender T thickens the wet resin just enough to hold that texture in place while it cures, instead of letting the sand sink and the surface flow flat. The result is a floor whose grip is locked into its structure and does not wear away with cleaning.

Where it is used

• Ramps, decks and drive lanes in multi-storey and basement car parks where wet tyres need grip
• Aircraft maintenance hangars and workshop bays exposed to oil, fuel and hydraulic spills
• Beverage, brewery and bottling-plant floors under constant washdown
• Dairy and food-processing areas needing a cleanable, liquid-proof surface
• Wet production and processing zones where standing water is routine
• Sloped walkways, loading docks and gangways requiring anti-slip safety
• Warehouse and light-industrial floors carrying regular foot and trolley traffic
• Plant rooms and utility areas where spills and hose-down are frequent

Key advantages

• Engineered anti-slip texture from broadcast quartz sand, safe even when wet or oily
• Rigid epoxy body with about 53 N/mm2 compressive and 20 N/mm2 flexural strength
• Good wear and abrasion resistance, with roughly 41 mg Taber abrasion loss
• Liquid-proof, seamless finish that keeps spills off the concrete beneath
• Easy to clean by scrubbing, pressure washing or scrubber-drier
• Wide RAL colour range for zoning, safety marking or a finished appearance
• Good resistance to many chemicals across the beverage and food sectors
• Single system suits car parks, hangars and food plants, simplifying specification

Limitations & considerations

• Concrete must be sound, at least 25 N/mm2 compressive and 1.5 N/mm2 pull-off, or the floor can debond
• Substrate moisture must be 4 percent by mass or below; above that a Sikafloor EpoCem moisture barrier is required first
• The textured, gritty surface is harder to wipe or mop clean than a smooth coating, and is not intended for polished aesthetics
• As an epoxy, it is less suited to sustained thermal shock, steam or the harshest wet-process chemistry than a PU-hybrid screed
• Application is temperature-sensitive: keep substrate and air between +8 and +35 C and at least 3 C above dew point to avoid blushing
• For experienced professional applicators only; pot life is short, about 25 minutes at +20 C

Industry use cases

How we position Sika Sikafloor MultiDur ET-05 HSR AP

Within the Sika range, ET-05 HSR AP is the anti-slip, textured member of the Sikafloor MultiDur family. Where a smooth decorative finish is wanted instead of grip, the self-smoothing Sikafloor MultiDur SL or the standard ET-05 AP coating are the natural companions, and both share the same Sikafloor-264 binder. For slabs failing the 4 percent moisture limit, pair it with Sikafloor EpoCem as a temporary moisture barrier before priming, and use Sikafloor-161 mortar to level rough substrates. Where thermal shock, steam or the most aggressive wet-process chemistry is the real challenge, step up to a polyurethane-hybrid screed rather than an epoxy coating. Across our other brands, Space Arc also supplies comparable heavy-duty and anti-slip flooring from Fosroc, MC-Bauchemie and Master Builders Solutions, so we can match the system to the exposure rather than force one product to do everything.
