Features & Benefits

• Uses:
  • Used internally in industrial buildings, for levelling and smoothing new or existing concrete and screed substrates in thicknesses from 5 to 40 mm
  • Can be used inside warehouse industrial areas and surfaces where rubber wheeled vehicles are in use
  • May be left as a finished floor due to its high mechanical strength and resistance to abrasion and thanks to its versatility, is suitable for numerous applications in the building sector for industrial use.
• Self-levelling product in powder form available in grey, made up of special quick-drying and quicksetting binders, specially graded silica sand, synthetic resins and special additives developed in MAPEI’s own R&D Laboratories
• Easy to apply either by hand or pump in thicknesses from 5 to 40 mm
• After setting, which takes place in only a few hours, Ultratop Industrial has a high level of compressive and flexural strength, bonds perfectly to the substrate and thanks to its special composition, dries quickly so that any further finishing coat may be applied after a very short time
• Complies with the principles defined in EN 13813 “Screeds and materials for screeds – Materials for screeds – Properties and requirements”, which defines the requirements applied to materials for screeds used in the construction of internal floors. Screeds and structural covering, such as those which help increase the load-bearing capacity of floors, are not included in this Standard. Resin flooring and cementitious screeds are included in this specification. They must bear the CE symbol, as illustrated in attachment ZA.3 Tables ZA1.5 and 3.3.

Preparation

• Substrates must be dry, solid and free of dust, loose and detached parts, paint, wax, oil, rust and all other pollutants. Apply a compressible band around the perimeter of the rooms to be laid and around any vertical elements which pass through the floor (such as pillars and columns)
• Concrete surfaces must be prepared by shot-blasting or grinding and primed with Primer SN and, where required, reinforced with Mesh 320 (glass fibre mesh) followed by a full broadcast of Quartz 1.2. After application, leave the Primer SN to dry for 12-24 hours, according to the surrounding temperature. Before casting the Ultratop Industrial, remove excess quartz with a vacuum
• Cracks in the substrate must be repaired beforehand using Eporip
• Pour the content of a 25 kg bag of Ultratop Industrial into a container with 4.25-4.75 l of clean water and continue mixing with a lowspeed electric mixer until a smooth, flowable, lump-free mix is formed
• Let it stand for 2-3 minutes and before applying, remix the blend for a few minutes more
• Only prepare the amount of Ultratop Industrial which will be applied within 15 minutes at a temperature of +23 C. The pot life of the mix varies according to the temperature and reduces as the temperature increases. If Ultratop Industrial is to be applied on medium to large-sized surfaces, larger quantities may be prepared using a verticalshaft mixer pump
• If it is mixed using mechanical means, the amount of water required is the same as when mixing by hand. Mix the product until the blend is completely homogenous before laying

Application

• Spread Ultratop Industrial by hand or with a pump in a single layer of 5 to 40 mm and a smoother for a natural finish. Make sure that the material is cast in a regular, continuous flow without interruptions, to avoid defects in flatness and differences in colour. Thanks to its self-levelling properties, Ultratop Industrial eliminates all imperfections left by the smoother
• When applying the product, respect the expansion joints in the substrate and form distribution joints at least every 50 m. With heated floors, the bay size must be no more than 25-30 m
• Seal joints with Mapeflex PU 45 FT single component, quick-hardening thixotropic polyurethane sealant and adhesive with a high modulus of elasticity for sealing expansion and distribution joints. Insert Mapefoam closed-cell polyethylene foam cord in the joint beforehand to obtain the required depth and avoid the sealant sticking to the bottom of the joint
• Floors made using Ultratop Industrial must be protected and then made non-absorbent using a Mapei finishing system. Choose the most suitable finishing system according to the finish or level of wear-resistance required
• Whilst still fresh, Ultratop Industrial may be cleaned from hands and tools with water
• Ultratop Industrial used pure: consumption 16.5-17.5 kg/m per cm of thickness.

Limitations

• Do not add more water to the mix once Ultratop Industrial starts to set
• Do not add lime, cement, gypsum or other binders to the Ultratop Industrial mix
• Do not use Ultratop Industrial on substrates which are subject to rising damp
• Do not use Ultratop Industrial for floating screeds. Ultratop Industrial must always be fixed to a solid, compact substrate
• Do not use Ultratop Industrial on wet surfaces
• Do not use Ultratop Industrial on metallic surfaces
• Do not use Ultratop Industrial at temperatures lower than +5 C or higher than +35 C
• The colours of floors made using Ultratop Industrial are not always uniform, a typical feature of cementitious-based products. Apart from the inherent nature of this kind of product, colour variations may also be caused by the way the product is applied. Also, it must be cast continuously without long pauses, in order to guarantee perfect flatness
