In concrete floors, even if covered with traditional hardening powders, "dust" is caused the abrasion and consequent wear of the friable components of the hardened cement paste: especially calcium hydroxide, also called free lime Ca (OH)₂, notoriously unstable from the chemical point of view, relatively soluble and intrinsically "friable". FLOOR VULKAN is made up of "hard" mineral aggregates (basalts, quartz and corundum) bound together by cement modified with micro-silicates (MICROSIL 90), which, by means of super-pozzolanic reaction (transformation of the lime released by hydrolysis during hydration, in new calcium silicate compounds that are stable, insoluble and resistant), and give the surface of the floor reinforced with FLOOR VULKAN very high mechanical performance and overall durability. FLOOR VULKAN exploits the mineralogical characteristics of the hardest materials present in the Mohs scale. It is made up of selected pure quartz (harder than quartz normally used in construction, Mohs scale = 7), Corundum (Mohs hardness = 9) and high hardness Basalt (very hard, tough and very wear-resistant effusive rock, Mohs scale = 7-8 ), which make up most of the aggregates contained in the mixture.

• Slip resistance, UNI EN 13036-4 (PTV): dry <75, wet <40
• Wear resistance, BCA UNI EN 13892-4: <=90 μ (class AR1)
• Drop test of a mass with spherical head diameter 20 mm and total mass 1000 grams, UNI EN ISO 6272: fall height 1600 mm INTEGRO-PASS, fall height 1700 mm INTEGRO-PASS.
The technical parameters set out above allow to fulfil standard 13813 (Materials for Screeds _ Properties and Requirements) and, above all, the strict standard 1504/3 (Products and systems for the protection and repair of concrete structures - Part 3: Structural repairs). Please note that the category of FLOOR VULKAN with regards to regulation 1504/3 is that of structural mortar R4, with the relative criteria of resistance to carbonation and adherence bonding after thermal cycles. The fulfilment of the structural parameters of regulation 1504/3 is of fundamental importance when dusting is carried out in severely exposed environments from the chemical point of view (carbonation, chemical attacks), from the mechanical point of view (flooring subjected to static loads and dynamic stress) or when dusting is carried out on fibre-reinforced concrete floors (especially in the presence of metallic fibre reinforcement). Produced in accordance with ACI 201 - 2R 77 - Guide to Durable Concrete: Section 3,4,6 "Recommendations for obtaining abrasion resistant surfaces".


Typical usages are:
- dusting of the dry mixture on fresh concrete surfaces: 1,2 - 1,5 kg/m²
- application in layers as for mortar on concrete surfaces (wet-on-wet): 15-20 kg/m²
- application on hardened concrete surfaces such as fishbone ramps, after laying a bonding element such as SYNTECH RGS: 20-30 kg/m²

Use fields

Anti-wear and anti-dust coatings of concrete surfaces subjected to high abrasion stresses: industrial flooring, road surfaces, airport flooring, ducts, overflows, such as:
• floors in industrial environments (metal and steel industries);
• flooring in areas for storage and handling of goods (logistics warehouses, depots, freight forwarders);
• paving of interports and airport hangars;
• flooring in commercial environments (shopping malls, supermarkets, shops, showrooms);
• loading/unloading platforms
• access slides to parking lots and garages in indoor and outdoor areas.

Use method

FLOOR VULKAN is a premixed product in 25 kg bags, ready to use, for application according to traditional methods (dusting or "pasting").
Surface dusting must always be carried out on fresh concrete, before setting has commenced, and can be carried out either manually or mechanically.

Application methods

- Apply by hand

- Finishing trowel

- Power trowel

Permitted supports

- Concrete

Warnings, precautions and Ecology

FLOOR VULKAN contains cement which, in contact with sweat, causes an irritant alkaline reaction and allergic reactions in those predisposed. Please note that the user is required to read the most recent Safety Data Sheet of the product, which contains chemical-physical and toxicological data, risk phases and other information regarding the transport, use and disposal of the product and its packaging in complete safety.
Technical data and performance data reported in this document are the result of laboratory tests conducted in a controlled environment and, as such, can be significantly modified by operating and installation conditions. Preliminary tests in the actual conditions of use are therefore required. The product and its packaging must not, in any case, be dispersed into the environment. Pay attention to the damp ageing and protection of exposed surfaces.
