Method of Coating with Protective Agent

Dirt not only interferes with the beautiful, but also contains let aggressive chemical composition of metamorphic sandstone. In order to prevent contamination and deterioration, easy to scrub, prevent water infiltration or to make sandstone more vivid, can adopt the method of coating with protective agent. At present, there are many kinds of protective agent products on the market, each for a different stone. The use of protective agent must take into account and adhesion of the stone ( sometimes sparkling ), whether the reaction and stone, surrounding climate plays a protective agent. Protective agent in the use of solvents can be divided into propylene radical emulsion ( water-based ), silicon and solvent ( chemicals ) three. Compared to silicon protective agent, solvent protective agent, water repellant effect on the color of the smaller.

3 indoor protective agent

Sandstone granular solid, good ventilation, must maintain a certain degree of freedom of breath. In general, the indoor humidity is relatively stable, not easily influenced by the weather, cold and wet. So, generally no expansion. Therefore, indoor basically may select any protective agent. It should be noted, protective agent after a period of time use to be coated again, this point and paint the same.

At the same time in the indoor use of protective agent must take into account the following situation: in advance whether for washing Sassafras, prevent wear, preventing the surface from food or oil pollution, easy to repeatedly brushing etc..

3 outdoor protective agent

Outdoor use protective agent to the attention of a lot of matters, in the official before brushing should fully consider the following environment:

If the sand placed on sand and gravel, sand and gravel due to water retention rate is high, do not have the best protective agent.

If the stone is placed in the cement structure, should choose to make the stone keep breathing (i.e., a small amount of the penetration of moisture into the rocks and then through the vapor volatilized ) protective agent, this is a crucial point. Usually acrylic emulsion ( water-based ) protective agent used for outdoor effect is more outstanding.

Outdoor protective agent to have the advantages of easy cleaning, free washing machine washing, brushing, polishing, processing with a hose or high pressure, can also be bleaching of natural fade and stains.

3 sandstone products storage and maintenance

Dirt and contamination not only interferes with the beautiful, but also contains let aggressive chemical composition of metamorphic sandstone. Is produced during construction or maintenance period of pollution, must be treated differently. General prevention is more important than cleaning, long-term maintenance effect is better than the sudden acute daily cleaning. Through proper design and material selection, careful construction and maintenance to reduce and prevent dirt stains. The right design, pay attention to the following things sandstone products pollution:

Graphic processing products, anticlinal coping stones, the walls of caves, water flows into the drainage did not require some narrow structure part, the water flows through the concrete, glass and other building materials surface and flow to the sand surface is very easy to cause the pollution of sandstone products. In the special environment, should choose and match the material nature of stone. For example, as the walls lining when in use, must guard against the front and lift switch of elevator near, furniture etc.. Incompatible combination between material is easy to produce pollution. (for example, automobile on sandstone surface leakage of liquid. ) laying in the deck or ladder permeable mortar will become the coal pollution. The joint error after the cleaning process is also an important reason.

The right approach include careful attention to the various links of transportation, storage, construction etc.. Thin panels not only crisp fragile, and it is easy to stain. Attention must be paid to stubborn stains mortar, coating, protective layer of stains, rust and lubricating oil scaffold.

From the storage period to the end of construction period, the stone must be as far as possible with the plastic layer or the antifouling cover cloth covers.

To fully understand the whole service process may be caused by internal and external due to pollution or contamination of human contact. Must be isolated from the pollution source, often cleaning dirt etc.. In polluted areas, using the cleaning agent cleaning stains coatings and building the appropriate. To clean the stone, should be moderate, to prevent harm or cause loss of the stone itself to the environment and workers. Considering the cost factor, cleaning should be economical and effective. Therefore, must be familiar with the following matters:

1 ) cleaning method and place convenient;

2 ) cleaning ability to feel loss caused to stone;

3 ) pollution degree of the surface;

4 ) it must be cleaned.

Protection of 3.3 sandstone.

Each stone has its own weakness, and a weakness is porous sandstone. The porous structure of the water easily penetrate into the. Once the sand absorbed moisture will lead to discoloration and chemical coloring. These spots will become part of sandstone inseparable. Therefore, the sandstone needs special care.

Do not use any type of cleaner or cleaning technology. Improper use of cleaning agent can result in serious consequences. Therefore, to check the label in the use of cleaning agents, before the test. If you find some adverse reactions should immediately stop using the.

If the sand table has been sealed, can take some simple cleaning method to protect it. The seal is very important step. A seal is sustainable for many years. Be careful in the use of sand table.

The timely removal of spill. Don't let the long time left in the sand table. Clean sand table to select neutral detergent or colorless and tasteless detergent. You can also choose to use dishwashing liquid mild. Do not use acidic cleaning agent. This detergent will corrode the sandstone polished surface.

Often wash the sand table and grouting. Don't put the detergent in the sandstone. If no prior cleaning can be soft brush off the residue. If there are stains scrub away, don't scrape. Repeated cleaning.

Occasionally deep cleaning. Deep cleaning also need to use a neutral cleaning agent. You can buy for deep cleaning of the cleaning tool design. Use a soft brush to remove stubborn residue. Cleaner sprinkle don't wipe it off immediately. Finally, to thoroughly rinse table, this step is very important.

Protective sand table to pay attention to the following suggestions:

1 ) sandstone cleaning agents must be neutral.

2 ) cleaning agent does not contain acid or citrus acid. These ingredients will damage the sandstone surface gloss.

3 ) be careful to use the vacuum cleaner with metal accessories. These attachments may scratch the sandstone surface.

4 ) do not try scouring powder or scrub cream, these products contain abrasive scratch sandstone surface.

5 ) avoid the use of tray under a glass.

6 ) don't put the high temperature vessels placed directly into the sand table. The best mat mat.
