Dec 10, 2019

In the decoration project, due to the special decorative effect of stone, it is widely loved by people, making the application of stone more and more widely, so people put forward higher requirements for the decorative effect of stone.

The maintenance of stone has become an important part of the process of building decorative stone. The "stone refurbishment" that is often mentioned daily refers to the stone that has been contaminated or damaged due to age, such as uneven stone surfaces, deep scratches, deep stains, etc. A set of different grinding discs and discs, from coarse to fine, is repeatedly polished and polished to restore the original appearance of the stone on the original basis.


01

Grease (grease, tar, cooking oil, milk, cosmetics)

Oil pollution will make the stone surface dull and dull. Chemicals are usually required to remove them completely. Using a soft cloth, apply a rinse-off liquid or household cleaner, mineral cleaner, or acetone. Paste cleaners are also available.


02

Organic pollution (coffee, tea, fruit stains, tobacco, paper, food, urine, leaves, bark, etc.)

Organic pollution will cause pink or brown marks on the stone surface, and these marks will disappear after the stains are removed. The stains of outdoor stone usually disappear in the sun, and will disappear after rain. Organic pollution in the room can be cleaned with 12% hydrogen peroxide plus a few drops and ammonia.


03

Rhenium metal (iron, rust, copper, bronze)

The pollution of iron or rust is orange or brown, and the shape is consistent with the shape of the source object, such as nails, latches, screws, jars, flower pots, metal furniture, etc. Copper and bronze contaminated colors are green or light brown. The reason for its pollution is that the rust of the bronze, copper, and brass is caused by the plate being placed in a humid environment, and the generated copper rust penetrates the rock surface. For metal contamination, use a paste cleaner. Deep-rooted rust is difficult to remove and may cause permanent contamination of the stone.


04

Microbial contamination (algae, mildew, moss, moss, fungi)

Stains such as ammonia, rinse aid, or hydrogen peroxide (1/2 cup per gallon) can be used for this stain. Note: Do not mix bleach with ammonia, as this will produce a deadly toxic gas.


05

Ink (Magic Pen, Pen, Ink)

Clean with bleach or hydrogen peroxide (only for light-colored stones) or paint thinner or acetone (only for dark-colored stones).


06

Paint

Paint small pieces of paint can be cleaned with paint thinner or carefully scraped off with a blade. After covering a thick layer of paint, the paint must be peeled off the stone surface with a special tool. Do not use acidic liquids or fire to remove paint on the stone surface. The paint stripper will scratch the surface of the stone, so it is usually re-polished. Use the paint stripper correctly according to the instructions in the instruction manual. After the paint is scraped off, wash it thoroughly with water. Wear rubber gloves and goggles during paint scraping and operate in a well-ventilated environment. Uncured or cured paint can be scraped off with a wooden or plastic spatula. Rubber and acrylic paints leave no trace after scraping. Oil-based paints, linseed oils, putties and sealants can cause oil contamination and leave traces.


07

Corroded traces

This kind of trace is caused by the acid substance remaining on the stone surface without being scrubbed in time. Some acidic materials will only erode the surface and will not penetrate into the corroded stone. Some will not only corrode the surface but also penetrate deep inside, leaving traces of corrosion. Once these signs of corrosion are removed, if it is marble, the surface must be wet with water, sprinkled with marble polishing powder, rub the powder on the surface of the stone with a wet cloth, or a low-speed electric grinding disc to grind. Continue grinding until the corroded traces disappear and the marble surface regains its luster.


08

Weathered

Weathering is a layer of white powder on the stone surface. The cause of weathering is that the mineral salt inside the stone rises from the inside to the surface with the circulation of water, and the water is formed by evaporation. When the water evaporates, the powdery substance remains on the stone surface. If new stone is installed, the surface dust can be cleaned with a rag or vacuum cleaner. It must be rubbed several times before the stone is completely dry. Do not wash these powders with water, this will only make the powder disappear temporarily.


09

Scratches and small nicks

The slight scratches on the surface of the cymbal should be polished with a dry plush abrasive disc, or treated with the above-mentioned method of removing corrosion marks. If it is a deep scratch or a small notch, it needs to be polished again.
