Treatment techniques for stone rust spots :
The causes of rust spots can generally be divided into two types:
The first type of rust is caused by the iron contained in the stone itself. Generally speaking, each stone itself contains iron components. When the rainwater comes into contact with the iron in the stone, it will gradually form rust spots. This rust is difficult to remove and takes a long time to process. Kelin KL608 strong rust remover can be used. It has strong permeability and can penetrate into the pores of stone surface to ensure the thoroughness of cleaning. It can effectively remove rust spots and not harm stone. Avoid using industrial hydrogen peroxide or other corrosive strong acid. Otherwise it will be self-defeating. The most important thing is how to prevent the regeneration of rust spots. The most effective method is to remove the rust and then protect it to prevent the water from infiltrating into the stone to avoid the regeneration of rust spots.
The second type of rust is foreign, such as steel sand left during processing or iron during construction, metal parts for decoration, etc. This rust is easier to remove, and the KL308 rust remover can be used. In general, it is quite difficult to completely remove the rust after the stone is produced. Therefore, the protective treatment before the installation of the stone is better than the protection after the completion of the work, because the external wall has a considerable height after completion, the construction is not easy, and there is also the possibility of contact with acid rain during the installation of the stone, so the protection before construction is The best is rust and dirt.
