- The tile joints of my flooring, especially in the kitchen, are blackish, dirty and difficult to clean
Any kind of natural stone, granite, limestone, agglomerate, concrete and terracotta has its absorbtion degree. If the surface is not treated with high quality protectors and an oily or greasy substance spills on the surface it will jeopardise the beauty of the surface almost in all cases.
You may solve the problem with the following application:
MGP 2 is a grey creamy substance; when it becomes a white powder, after 10-15 hours, it has finished to act and should be eliminated with a cloth.
If a mark is still visible repeat the application until complete cleaning.
If the color of the surface looks lighter after the application of MGP 2 it is due to the full cleaning of the surface. To have an even surface clean the whole area with MGP 25 or apply MGP 2 on the whole area. The surface will be so clean and ready to be treated.
There is a graffiti on:.
Natural stone surfaces, sandstone, limestone, granite, unpolished marble, present a superficial porosity which holds back the dirt, that can be also caused just by walking on it. This happens not only on natural stone surfaces, but especially on brushed or rough porcelain stoneware, and on light colored surfaces, where generally dirt comes from shoeprints, bike wheels, shopping carts etc.
Even if floorings have been treated with anti stain sealers or water repellents the above mentioned materials remain porous and therefore they hold back the dirt in its superficial pores, while liquid dirt substances would not penetrate into the treated stone.
The cleaning of the surface depends on the dirt: if it is food traffic dirt we suggest to use MGP 25, diluted following the specifications
If it is building site dirt, dust or concrete residual, we suggest to use UNICLEAN on natural stone, marble, granite etc. diluted following the specifications.
On porcelain stoneware we suggest to use CER CLEAN ULTRA, diluted following the specifications.
When the surface is clean apply STONE P, using a simple cloth or a low pressure gun if you have a very rough surface, like bush hammered or flamed.
Generally 2 coats of STONE P have to be applied, at a distance of 2 hours one from the other. This product closes the superficial porosity so to prevent foot traffic shoeprints.
In high foot traffic areas the application of the product should be repeated when needed, without creating overlaps or unaesthetic differences.
After this finish with STONE P the surface can be cleaned with MGP 24 or another not aggressive, neutral detergent, because dirt does not penetrate and just a simple cleaning of the floor is needed.
