About Sika Sikafloor MultiDur EB-15 AP

Sikafloor MultiDur EB-15 AP is not a single tin you roll out; it is a defined build-up of Sika resins that together form a 1.5 mm epoxy floor with a deliberately roughened surface. The sequence is a Sikafloor-161 epoxy primer to seal and grip the concrete, a Sikafloor-264 body coat into which 0.4-0.8 mm quartz sand is broadcast to refusal, and a Sikafloor-264 seal coat that binds the exposed grain into a hard, closed-but-textured finish. Because the aggregate stands proud of the film, the floor keeps its slip resistance even when wet, which is exactly why it is specified for beverage and food plants, wash-down bays and ramps rather than a glass-smooth self-levelling coat.

For an Indian project the appeal is practical. The system carries good chemical and mechanical resistance, a wide range of RAL colours for zoning and housekeeping, and a liquid-proof surface that keeps spills off the slab. It suits floors seeing normal up to medium-heavy wear, so it sits comfortably between a thin roller coating and a full heavy-duty screed. As Sika’s authorised distributor and applicator, Space Arc supplies the matched components and the on-site know-how to lay them correctly across Delhi NCR and pan-India, so specifiers get a system that performs the way the technical data sheet promises.

The technical insight

The performance of EB-15 AP comes from separating two jobs that a single coating cannot do well at once: mechanical grip and wear protection. A smooth epoxy film is hard but slick, and once a wet or oily film sits on top the coefficient of friction collapses. By broadcasting angular 0.4-0.8 mm quartz sand into the wet Sikafloor-264 base and then locking it under a seal coat, the finished surface presents thousands of hard mineral peaks that break through liquid films and give the boot or tyre something to key against. At the same time those quartz grains, not the resin, take the brunt of abrasion, so the epoxy binder is protected and the floor holds its texture far longer than a plain coating would. The result on test is a hard, tough surface, with roughly 53 N/mm2 compressive and 20 N/mm2 flexural strength, a Shore D hardness around 76 and Taber abrasion loss near 41 mg, all backed by an epoxy chemistry that is inherently resistant to the acids, alkalis and cleaning agents common in food and process environments.

Where it is used

• Storage and assembly halls with normal to medium-heavy foot and trolley traffic
• Maintenance workshops and engineering shops where tools, oils and mechanical wear are routine
• Garages, service bays and loading ramps needing wet slip resistance
• Multi-storey and underground car park decks and drive lanes
• Beverage bottling and packaging lines with frequent wash-downs
• Food processing and preparation areas requiring a hygienic, liquid-proof floor
• Dispatch and goods-in zones where pallet trucks and spills meet
• Colour-zoned production floors using RAL shades for safety demarcation

Key advantages

• Broadcast quartz texture gives dependable slip resistance even on wet or contaminated floors
• Good chemical resistance against the acids, alkalis and cleaning agents typical of food and process plants
• Strong mechanical performance, around 53 N/mm2 compressive and 20 N/mm2 flexural strength
• Hard, abrasion-resistant wearing surface (Shore D approx. 76; Taber loss approx. 41 mg)
• Liquid-proof, seamless finish that keeps spills off the concrete and is easy to hose down
• Wide range of RAL colours for housekeeping, zoning and safety markings
• Matched Sika component system removes guesswork on compatibility between primer, body and seal coats
• Straightforward multi-layer application within a manageable temperature window

Limitations & considerations

• Not a single-product coating; it is a three-stage build (primer, broadcast base, seal) that needs sequencing and skilled labour
• Short working window once mixed, with pot life around 25 minutes at +20 degrees C, so batches must be sized to the crew
• Substrate is critical: concrete moisture must be below about 4 percent and ambient RH under 80 percent, or bond and cure suffer
• Application temperature is limited to roughly +8 to +35 degrees C, which needs planning in Indian summers and cold-store settings
• The textured, aggregate finish is harder to deep-clean than a smooth self-levelling floor and is not intended for ultra-hygienic mirror finishes
• At 1.5 mm it targets normal to medium-heavy wear; genuinely heavy impact or thermal-shock areas call for a thicker screed

Industry use cases

How we position Sika Sikafloor MultiDur EB-15 AP

EB-15 AP sits in the middle of Sika’s broadcast flooring range: choose the lighter Sikafloor MultiDur EB-10 AP where wear is only light to normal, or step up to a thicker EB-24 style build for heavier mechanical duty. Where the priority shifts to a smooth, mirror-finish hygienic floor rather than a textured one, a Sikafloor self-levelling system is the better fit, and the whole build-up leans on Sika’s own Sikafloor-161 primer and Sikafloor-264 resins. Within our wider catalogue, teams facing steam and thermal-shock cleaning in food plants often pair or compare it with a polyurethane-hybrid screed such as Fosroc Nitoflor TF 100 UH, where standard epoxy is pushed beyond its comfort zone.
