Causes Of Stone Rust Spots

The first kind of rust is caused by the iron content in the stone itself. Generally speaking, each kind of stone contains more or less iron. When the rain comes into contact with the iron in the stone, it will slowly form rust spots. This kind of rust spots are difficult to remove and need to take a long time to deal with. You can use Kelin KL608 strong rust remover, which has strong permeability, can penetrate into the surface pores of the stone, ensure the thorough cleaning, can effectively remove the rust spots without damaging the stone, Avoid using industrial hydrogen peroxide or other corrosive strong acids, 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 conduct protective treatment immediately after rust removal, so as to prevent water from seeping into the stone again and avoid the regeneration of rust spots.
The second kind of rust spot is foreign, such as steel sand left during processing or iron ware during construction, metal parts for decoration, etc. This kind of rust spot is easy to remove, and can be removed with KL308 rust remover. Generally speaking, it is not easy to completely remove the rust spots on the stone. Therefore, it is better to conduct protective treatment before stone installation than to conduct protective treatment after completion, because the external walls are quite high after completion, and construction is not easy, and there is also the possibility of exposure to acid rain during stone installation, so it is best to conduct protective treatment before construction, which can prevent rust and dirt.
