About this product
weber.floor 4610 industry top is a pumpable, rapid hardening, self-levelling screed intended for use as a surface layer on industrial flooring. The material is especially suitable where renovation time is limited, weber.floor duro top is ready for normal traffic loading without further finishing; but may be coated with a suitable resin should this be required.
Field of application
weber.floor 4610 industry top is designed for use in industrial environments on both new floors and renovation projects. It is used for levelling and smoothing of floors subject to heavy traffic and abrasion, such as factories, production areas and warehouses. weber.floor 4610 industry top is used as a wearing surface applied directly to the substrate or on top of weber.floor 4600 industry base and weber.floor 4602
Technical data
Working instructions
Light ventilation in the work area is necessary but windows and openings must be closed sufficiently to avoid draughts during and after application. Indoor and floor temperature must exceed +10C during and after application and one week after that. The relative humidity of the concrete floor must not exceed 95%. Dehumidifiers must not be used for the first two days
Substrate
weber.floor 4610 industry top is designed primarily for use on concrete substrates. Surface tensile strength of the substrate should be a minimum 1.5 N/ mm2. Any shrinking in newly cast concrete should have ceased otherwise reflective cracking may occur. Weaker or uneven substrates should be smoothed using weber.floor 4610 industry top, or weber.floor 4602 duro base extra. Weak (less than 1.0N/mm²) or softer substrates, such as asphalt flooring must be removed. During application the temperature of the substrate should be above +10°C.
Preparation and priming
The substrate should be clean, free from dust, grease or other impurities that might prevent adhesion. Holes and leaks in the substrate should be sealed. Floor drains etc. should be protected with lids and separated with stop ends. Large irregularities (>30 mm) should be filled in. The infil should be left to harden before the next application. The substrate should be mechanically prepared, vacuum cleaned and primed with weber.floor 4716 primer according to the instructions on the data sheet. After application and whilst the primer is still fresh, it should be lightly brushed to ensure a complete uniform film has been applied. The function of the primer is to improve adhesion to the substrate, to prevent air bubbles and to prevent dewatering of the floor compound before hardening.
Mixing
weber.floor 4610 industry top should be applied using a mixer pump approved by maxit. The material is mixed with 21% water, which corresponds to 5.25 litres per 25Kg bag. Do not use excessive water. While mixing, the water content should be checked continuously by the flow ring test. Also ensure that the material is correctly mixed and free from separation. It is important to add the stipulated amount of water as excess water will reduce strength, increase shrinkage and encourage segregation. Conversely reduced water content increases viscosity. The temperature of the mix should ideally be between +15C and + 20C.
Application
The maximum width of the pumpable area varies from 6-8 metres depending on the pump capacity and application thickness. Wider areas can be temporarily divided with stop-ends. Pumping is carried out in sections so that a new section is pumped as quickly as possible in order to maintain a wet edge. A wide spatula or spiked roller should be used to assist the self levelling process.
Drying time
The screed can receive foot traffic after a drying time of 2-4 hours at an ambient temperature of +20C; will receive Forklift wheeled traffic after 24 hours and full traffic after 7 days.High humidity of the substrate and poor drying conditions prolong the setting time.
Storage and Shelf life
Storage time in dry conditions and closed packages is 6 months.

Health and Safety
Hazardous – contains cement, which is alkaline when wet and can cause skin irritation. Use eye protection, gloves and barrier cream and avoid prolonged skin contact. Avoid inhalation of dust.Wash skin contamination away with warm, soapy water. Remove splashes to the eyes by prolonged irrigation and consult a doctor. Do not ingest. Refer to Health and Safety Data Sheet.
