Among the many marbles, white marble is undoubtedly one of the most widely used stones, but the hypocritical, fragile, and difficult to wait for white marble in anti-fouling have made some users regret it. So, what are the external reasons for the yellowing of white marble? Next, let’s take a look with the editor of FABULOUS Group
yellowing caused by the installation process
The yellowing of the stone related to the installation is mainly caused by two aspects. One is due to the size of the installation, and the on-site cutting destroys the original waterproof treatment on a certain side; the other possible situation is that the construction environment is dirty and the construction is in progress. The cement slurry falls on the board surface. In order to prevent the falling cement slurry from drying up on the board surface, wipe the falling cement slurry with a wet towel. At this time, it is very possible to wipe some strong alkaline cement water into the board surface. Dark cracks, because even if the board surface has been treated with permeable waterproofing, it is impossible for the tiny water-repellent molecules to form a protective film across the cracks to shield and protect the cracks. Therefore, the coverage of the waterproofing agent at the cracks is very limited. When installing, use a gray knife to scrape the side of the specification board with cement paste back and forth, which will also destroy the waterproof treatment that has been done. If the cement water is accidentally brought into the cracks of the board when wiping the board, the yellowing of the board is a matter of time and not whether it will turn yellow.
yellowing caused by waxing
When wax is used to polish the marble surface, the thick wax layer turns yellow due to its own aging.
yellowing caused by crystal face treatment
The steel wool used for crystal surface treatment, with tiny fine powder remaining in the micropores of the polished marble slab, becomes the source of yellowing. Especially when the marble is treated in a wet state, yellowing is prone to occur.
yellowing caused by wear
As the polished surface of the marble wears away, dirt is brought into the pores of the marble surface with walking, and these dirt make the white marble surface yellow.
Yellowing caused by incorrect care
The most common incorrect care is to mop the floor wet with a dirty mop. Dirt brought by the dirty mop accumulates in the marble, making the surface of the marble contaminated and yellow.
