Etching Repair
The etching repair process depends on how deep the etching has gone into the marble. First of all we would try and remove the etching with marble polishing powders, we would do this with a hand machine, soft pad and a bit of water. The powder has little bits of grit that tries to scratch away the etching. If this is successful then that’s it. If it is still there then we have to go through with the diamond pads and polishing. The diamond grade depends on the severity of the etch. For example, if it was a two hundred grit we would follow all the way up to a 1500 grit done with a hand machine. Once this has been done we apply polishing powders and machine polish and rinse the area.
Chip Repair
Most chip repairs are done on benchtops and they are done on the side corners or edges of the benchtop and they can be done with fillings of two-pack epoxy to get a colour that suits the benchtop. Also, we can fill it with a gel that can be cured with a UV light. Once we have done the UV light process we use fine emery paper to shape the repair and go through the grades. Once we have gone through the grades we apply polishing paste and polish until it has the same shine as everywhere else.
Stain Removal
Normally would consist of poultice. Poultice would be applied as a paste format. A powder that is mixed up as a paste. This is applied to the stained area. We would apply polythene and tape off the area of the polythene so everything is sealed off. The whole idea of this is to make it sweat and make the stain rise and come out open the pores and make it come to the top of the stone. This is normally done over a period of 24-48 hours. Once this has been done we remove the poultice and rinse the area with carbon soda.
Really stubborn stains
Staining all depends on how early you catch the stain. If the staining has been there for two years the chances are it won’t come out. The best results for stain removal are when its less than 3-4 months old. It all depends on how far it has penetrated into the stone.
