Fields of application

weber.floor 4720 is suitable for strengthening absorbent concrete or cement-based screeds, based on Portland cements.
Can be used on industrial floors that are subject to high mechanical and thermal stress, e.g. in the metal-processing industry and in foundries with traffic of heavy forklifts with rubber and polyamide tyres.
For indoors and outdoors.

Main features

• very good penetrative properties
• highly strengthening effect
• reduces oil penetration
• highly water vapour permeable
• withstands high levels of thermal stress
• watery and odourless
• very easy to use
• fast drying
• environmentally friendly; solvent-free

General notes

• weber.floor 4720 does not form a sealed film on absorbent floors; it reacts with components of the cement-based substrate to form a glass-like, extremely hard silicate structure that provides a strengthening impregnation within the surface of the existing mortar matrix.
• Surfaces treated with weber.floor 4720 can be left without any covering. However, the product is suitable for strengthening concrete floors and cement-based screeds in the case of covering with reactive resin coatings.

Special notes

• Standing water can leave white edges after it dries off. The removal of such stains is nearly impossible.
• Strengthening of highly polymer-modified, cement-based smoothing mortars is not possible due to their low porosity.
• Relative humidity rate while drying: max. 85 %
