FABER Honing & Polishing – A1 Grey

Natural-effect polishing powder for delicate marble surfaces and lime-based materials with a high sensitivity to acid.


A1 GREY is a high-performance polishing powder with a formula that is completely wax free and low in acid content. A1 GREY can be used to polish delicate marble surfaces and all of those materials that are particularly sensitive to acids and which otherwise are at risk of developing an “orange peel-effect” finish following the use of aggressive products. A1 GREY reacts with the material to which it is applied, boosting shine. At the same time, it gives treated surfaces a good, long-lasting level of resistance to dirt and foot traffic. This product can achieve perfectly polished surfaces on more delicate materials, without creating blemishes or compromising aesthetic results.


A1 GREY can be used on all materials that cannot be polished using acid-based or aggressive products. It also offers excellent results on all lime-based surfaces. A1 GREY, like all polishing powders by Faber, will maximise the effect of the polishing process, making the whole operation much simpler by effectively replacing the time-consuming final steps in the mechanical polishing process. This means it is possible for the operator not to have to use end-stage polishing grains, which drastically cuts the time, energy, effort and the amount of water needed to complete the polishing process.
