weber.floor 4600 industry base 

weber.floor 4600 industry base is a rapid hardening, pump applied industrial Flooring system. The material is supplied as dry powder based on special cement, additional binder and additive. It is supplied as a pre-blended dry powder designed for application at a thicknesses of between 5 and 30mm in one operation.

weber.floor 4600 industry base is intended as a levelling and substrate to weber.floor 4610 industry top, weber.floor 4630 and weber.floor 4650 design colour on uneven concrete substrates. The material is also intended for spreading the load on weak concrete substrates. On floors with extra high loads weber.floor 4602 is recommended.

weber.floor 4600 industry base is mainly recommended for concrete substrates. The surface tensile strength of the substrate should be minimum 1.0 N/ mm2. Weak and non-rigid substrates, such as asphalt floors, must be removed. Shrinkage movement in newly cast concrete should have finished, otherwise reflective crack formation might appear.

The substrate should be clean, free from dust, grease and 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 mechanically prepared before the next application and the surface vacuum cleaned and primed with a 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 de-watering of the floor compound before hardening.

weber.floor 4600 industry base should be applied using a mixer pump approved by Weber. The material is mixed with 17-18% water, which corresponds to approx. 4.25-4.5 litres per 25kg bag. Do not use excessive water. While mixing, the water content should be checked continuously by the flow ring test to ensure that the material is correctly mixed and free from separation. It is important to add only the recommended 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.

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 the new section is pumped as quickly as possible to maintain a wet edge. A wide spatula or spiked roller should be used to assist the self levelling process.

The screed can receive foot traffic after a drying time of 2-4 hours at an ambient temperature of +20C. The floor can be covered with weber.floordurotop after 8-12 hours depending on the layer thickness and drying conditions. High humidity of the substrate and poor drying conditions prolong the setting time.

Storage time in dry conditions and closed packages is 6 months. For deliveries in bulk the store time is 3 months; longer times may have an impact on the levelling properties.
