CEMENTITIOUS SCREED Self-levelling industrial floor screed based on special hydraulic binders for abrasion-resistant flooring, thickness from 5 to 40 mm CLASSIFICATION ACCORDING TO EN 13813 Smoothing layers of Ultratop Industrial applied according to the specifications in this Technical Data Sheet are classified as CT - C40 - F10 - A9 - A2fl-s1 in compliance with EN 13813 Standards. WHERE TO USE Ultratop Industrial is used internally in industrial buildings, for levelling and smoothing new or existing concrete and screed substrates in thicknesses from 5 to 40 mm. Ultratop Industrial can be used inside warehouse industrial areas and surfaces where rubberwheeled vehicles are in use. Ultratop Industrial 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. Some application examples • ew floors in workshops, factories, store rooms, plant N rooms, garages and warehouses. • brasion-resistant floors on concrete and screed. A • ndustrial floors that must be protected with epoxy I coatings and paints in chemical and food processing plants, textile mills and tanneries. TECHNICAL CHARACTERISTICS Ultratop Industrial is a self-levelling product in powder form available in grey, made up of special quick-drying and quick-setting binders, specially graded silica sand, synthetic resins and special additives developed in MAPEI’s own R&D Laboratories. When mixed with water, Ultratop Industrial becomes a self-levelling compound which is 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. Ultratop Industrial is classified as CT - C40 - F10 - A9 A2fl-s1 according to EN 13813:2002 Standards. CT refers to a cementitious-based product, C40 and F10 refer to the compressive strength and flexural strength, respectively, after 28 days, A9 is the Böhme abrasion-resistance coefficient and A2fl-s1 is the fire-reaction class. Ultratop Industrial 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. RECOMMENDATIONS • o not add more water to the mix once Ultratop D 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 (consult the MAPEI Technical Services Department). • 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...
