Granite specific protectants (Fuding black, Shanxi black, Mongolia black, etc.)

    Granite during installation, stone plate will appear "watermark" plaque, with inlay hardening of the mortar and dry, "watermark" will slightly reduce, and even some disappeared, the isolated and scattered appeared in the plate, however, with the passage of time, especially outside the household repeatedly encounter rain or wet weather, water from the seams or stone surface and other parts of the invasion, natural stone water spots gradually become larger and in slab connected and local sector deepened, shiny dark, seam concurrent precipitation white crystals, for many years not to fade, serious impact on the appearance, this kind of phenomenon is called efflorescence. There are 4 main reasons:

       1. Natural stone material crystallization is relatively coarse, there are many invisible to the naked eye capillary, granite pore rate of 0.5 ~ 1.5%, marble pore rate was 0.5 ~ 2.0%, the impermeability performance than ordinary cement mortar, granite water absorption rate of 0.2 ~ 1.7% is lower, the water still by through the stone of capillary immersion surface are transmitted to the other side. Natural stone of the characteristics and the pores, as the adhesive material in water, alkali, salt and other substances and infiltration of precipitation and the formation of efflorescence provides the channel.

       2.Main component. Stone is calcium carbonate, account for more than 58 percent, when subjected to atmospheric sulfur dioxide and the role of moisture, the surface from chemical changes that is transformed to gypsum, which soon lose luster, and became loose and porous.

       3.adhesive material containing alkali, salt and other ingredients. Mainly for mounting paste mortar precipitation of Ca (OH) 2 (calcium hydroxide) and follow the excess mixing water, along the pores of the stone free plate invasion, mixing water more, move to the surface mortar Ca (OH) 2 more, after the evaporation of water, Ca (OH) 2 is accumulated in the plate.

      4.water infiltration, surface water (or wet) along the stone surface and gaps invasion stone plate, and dissolved Ca (OH) 2 and other salts into stone capillary form efflorescence. Obviously, water is the solvent and carrier material efflorescence.

         SICONG & reg; KY-101 high density granite special protective agent have a stronger ability to penetrate, effectively penetrate stone pores Neda 3-5mm and stone fully integrated form a deep and lasting protection layer, surface without leaving any traces, don't change color stone, do not affect the stone's air permeability, can effectively prevent the subtidal infiltration, and prevent water and pollution from external intrusion. With stone bottom surface sealant KY50 or stone interface increase adhesive KY55 used in conjunction with, can effectively prevent the stone water variegated stem, salting out Fanjian (Baihua), spit yellow and other disorders. The protective agent has excellent anti aging, anti ultraviolet, weathering resistance of more than 10 years, the main active ingredients is FDA (U. S. Food and Drug Administration) approved material and products cured in contact with food, no any toxic and it not harmful to the human body.

   The product is a kind of protective agent based on high density granite. Dark colored granite, as its name suggests is refers to the color of black or black and low water absorption of granite (such as: Changtai black, Shanxi black, Mongolia black, etc.). This kind of stone is common characteristics of high density, low water absorption rate (water absorption ratio). Common for example of granite with permeable protective agent in containing silicon material can not be effectively infiltrated into the stone and in the surface of the stone to form lines like residual, affect the stone's overall appearance and protective effect. The protective agent has stronger penetration ability against, effectively penetrate stone pores Neda and stone fully integrated form a deep and lasting protection layer, surface without leaving any traces, don't change color stone, do not affect the stone's air permeability, can effectively prevent the subtidal infiltration, and prevent water and pollution from external intrusion. With stone bottom surface sealant or stone interface increase adhesive used in conjunction, can effectively prevent the stone water variegated stem, salting out Fanjian (Baihua), spit yellow and other disorders. The protective agent has excellent anti aging resistance, ultraviolet resistance, weatherability of years, the main active ingredients are the United States (the United States Food and Drug Administration) approved material and products cured in contact with food, no any toxic and it not harmful to the human body.

Construction method:

1, stone must be dry, the stone surface clean, maintain good ventilation in the construction site.

2, the protective agent directly with the brush in stone material surface coating, crisscross full brushing omission shall, after brushing besmear of stone material surface should be a certain amount of liquid membrane for the absorption, and in minutes with rag to wipe off the surface residual medicament. Square meters of stone for each liter of protective agent.  

3, after the treatment of the stone material, hours after the protective effect. After a week, the protective effect of natural conservation is the best.

4, stone veneer using wet installation and construction, stone bottom face suggested using the bottom of a stone strength surface sealant or stone interface increased with the use of adhesive, protective effect is better.  

5, the product can be used in winter low temperature (0 degrees Celsius). Summer construction should avoid excessive exposure to the stone floor, resulting in the surface temperature is too high (above 50 degrees Celsius), due to excessive drying lead to the increase in the dosage of chemicals, and hinder the penetration of the coating.  

6, the original packaging sealed storage period of two years, two years after the test results remain unchanged, can continue to use

Matters needing attention：

1, high acid environment is not conducive to the quality of the product (stone after acid cleaning agent, must be the residual acid to sodium carbonate solution and to neutral, otherwise the maintenance of failure).  

2, recommended to do sample test for unfamiliar stone, for at least 24 hours reaction.  

3, any harsh chemicals contact and cleaning, may affect its effective life.  

4, placed in children can not touch the place.
