Steps of Design
• Think of the situation
• Build up a concept of stone matching
• Cost control
• Quality control
Please do not feel hesitation to consult us!
Stone Treatment & Maintenance Proprietary and Confidential 13
Step 1 of DesignThink of the situation
• Exterior: Facades, square, fountain, paver…– Geography: Inland, mountainous, or by the sea (salt fog)…– Weather: Wet, hot, cold or a city existing big temperature difference which may
damage the exterior travertine material. – Location: Downtown (acid rain, corrosive air, dust…), traffic…
• Interior flooring– Traffic– Wear & Abrasion: High heels, bottom of shoes…– Impact of heavy articles– Source of Pollution: Tea, oil, coffee, cola, juice…
• Interior walls, handrails, skirting…– Possible impact
• Guestrooms/toilets– Source of Pollution: Tea, oil, coffee, cola, juice, water, red wine…– Easy to clean
• Swimming pool/SPA– Water resistance– Source of Pollution: acid/alkaline etch, grease, food, water…
• Restaurants– Source of Pollution: Oil, wine, food, drinks, smokes…– Impact of heavy articles
Stone Treatment & Maintenance Proprietary and Confidential 14
Step 2 of DesignBuild up a concept of stone matching
• Decide a sort of stone for a specific area– Safety Safety for the construction or specific part of a construction. Safety for the health of human, harmful radiation and gases of some sort of stone.– Longevity Impact/ wear and abrasion/ water resistance… Weathering and aging Possible corruption during use– Economy– Facility: Easy to maintain
• Decide a stone brand to decorate a specific area– Size– Color– Texture– Uniformity
• Evaluate the availability– Some brands of stone have very small output.– Every piece in the same block looks very different.– Exhausted reserves may lead to the replacement impossible.
Stone Treatment & Maintenance Proprietary and Confidential 15
Step 3 of DesignCost control
• When choosing a product/brand of a sort of stone– Place of origin, volume of reserves, difficulties in mining, transportation,
may extremely wave the costs.– Stone being an art of the nature, colors, texture, and the uniformity may
decide the costs.
• When processing in the factory– To determine how precisely the uniformity of the pieces you expect to
have, will extremely matter for the costs.– Every chunk of raw stone is mined based on regular sizes, your particular
request on sizes will increase the wastage during cutting.– To endure the impact and weight on the surface, you have to consider
the thickness of stone based on the wearing coefficient and impact strength of the stone, which directly decides the costs.
– Faking the work by saving steps and using low quality material during processing, will extremely decrease the longevity of stone. .
– Higher quality raw material, e.g., anchors, resins, adhesives, stone sealers, will increase the costs but can extend stone’s longevity and save maintenance costs in daily use.
Stone Treatment & Maintenance Proprietary and Confidential 16
Step 4 of DesignQuality control
• Specification of raw material for processing should be included into your design.
– Low quality adhesives and fillers will cause the stone yellowing.– Low quality iron anchors without antirust treatment will cause the stone
yellowing.– Low quality or inappropriate stone sealer will limit stone’s resistance of
specific pollutions.
• Specification of installation should be included into your design.
– Strict procedure.– Strict control of procedure.
• Specification of daily maintenance should be included into your design.
– Appropriate cleaning chemicals for daily cleaning based on the chemical properties of the stone.
– Specification of regular surface treatment, e.g., raw material/ processing of crystallization.
– Other maintenance and repair regulations.

Installation
• Protecting the stone• Paving• Grout line treatment• Polishing• Crystallization
Please do not feel hesitation to consult us!
Stone Treatment & Maintenance Proprietary and Confidential 18
InstallationProtecting the stone
• Choose a sealer based on what sort of stone it is.– Impregnation sealer: smooth and leaktight stone suface.– Coating sealer: rough surface (The bottom face has to be sealed
perfectly)
• Choose a sealer based on what resistance the stone will need.– Water resistance– Oil resistance– Salt resistance (Seafront buildings or swimming pool)– Acid/alkaline resistance (restaurants, bathrooms, tables)
• A hexahedron protection– The bottom face: LONG TERM water/ acid/ alkaline resistance for the
penetration of cement mortar.– 4 side faces: water resistance– Top face: based on the situation
• Required duration of sealing for interior stone– Sealing for the bottom face: >15 years.– Sealing for the side faces: >10 years.– Sealing for the top face: >2 years.
Stone Treatment & Maintenance Proprietary and Confidential 19
InstallationPaving
• Methods for paving– Flooring Dry paste method Wet paste method– Walling Wet paste method for skirting and low area. Dry-hanging method for high place walling. G.P.C. method for 30m higher buildings– Fountain Wet paste method– Swimming pool Wet paste method
• Problems may exist during paving– Iron nails and anchors without antirust treatment may cause stone
yellowing and leave penetrative rust stains on the surface.– Low quality glues may loosen stone and cause accidents and some will
cause the stone yellowing.– Inadequate leveling and immediate use without complete solidification
will cause hollowing under the stone.
Stone Treatment & Maintenance Proprietary and Confidential 20
InstallationGrout line treatment
• Color – The color or effect of the filler should be in consonance with the stone, or– Should be a bit lighter than the stone. – But a filler of brighter hues can make some dark-colored stone more
elegant.
• Weathering/ Aging resistance– Sulfur dioxide and other air pollutants in the air may cause weathering and
aging of the filler in the grout lines.– UV and temperature changing may cause the filler yellowing or darkening.– Water may dissolve the filler and cause the grout lines nude again.– The filler in the grout lines might be abrased and worn away during use.– The pressure from different expansion coefficient between the stone and
the filler may cause the grout lines loose the filler.
• Longevity– The longevity of the filler depends on the quality and the environment of
the grout lines.– The filler in the grout lines needs to be sealed for water/oil/chemical
resistance in daily use.
Stone Treatment & Maintenance Proprietary and Confidential 21
InstallationPolishing
• Polishing only can be started after the adhesives under the stone are completely solidified.
• If polishing has to be required during installation, the stone then doesn’t need so shinning in the factory, which can save some costs by saving some polishing steps in the factory.
• The stone and the grout lines should be sealed for water resistance before polishing.
• The holes and cracks of travertine should be filled well before polishing.
• Water may cause rusts and should be used cautiously for polishing.
• Choose appropriate grinding tools according to the chemical and physical properties of the stone.
Stone Treatment & Maintenance Proprietary and Confidential 22
InstallationCrystallization
• Most of stone problems are caused by wrong crystallization procedure and low quality crystallization material.
• Choose a crystallization method based on the chemical and physical properties of a stone.
• Wax-based emulsion may jam the vessels of the stone and limit air exchange of the stone. Rusts may happen in marbles and white stain may occur in granites.
• Some crystallization material is powder, which needs to be dissolved with water before use, will cause rusts and yellowing.
• Too frequent crystallization treatment will cause aging and damage the structure of the stone.
• Be cautious of the PH value of the material.

• Rusts (Yellowing)• Efflorescence• Etching• Aging• Mold• Water Stains• Oil Stains• Colored Stains
Please do not feel hesitation to consult us!
Stone Treatment & Maintenance Proprietary and Confidential 27
Rusts (Yellowing)
• Causes– The Stone wasn’t sealed or has lost the sealer’s water/chemical resistance.– The stone has iron and other metal ingredients itself. Different oxides
appear different colors.– Some metal tools during installation, nails, anchors, can leave penetrative
rust stains from the bottom to the surface. – Unprofessional polishing and crystallization procedure will leave water in
the water, which reacted with metals and caused rusts.– Empty grout lines will allow water penetrate into stone and cause rusts.– Too much water residue on the surface during cleaning, may penetrate
into stone through low quality sealers, and cause rusts.
• Advices for treatment– Some acid rust removers may aggravate rust stains on the surface.– Some penetrative rust stains, as you may see from the second picture at
the right side, can’t be removed entirely. To change the part of stone is a wise decision.
– To treat the rusted surface, wet polishing is negative before the grout lines are filled and the surface is sealed.
– Allow the stone “breathe” and exchange vapor with the air for some time before crystallization.
Stone Treatment & Maintenance Proprietary and Confidential 28
Efflorescence
• Causes– The Stone wasn’t sealed or has lost the sealer’s water/chemical resistance.– Natural stone has vessels which may bring the alkaline material of the
cement to the surface. And the dry white residue on the surface is called efflorescence.
– Without immediate treatment, the first efflorescence will react with CO2, SO2, SO3 in the air, and produce more stubborn and hard white stains.
• Advices for treatment– Unprofessional cleaners will etch the stone and leave ugly etch stains.– Use highly penetrative efflorescence removers to dissolve the
efflorescence in the vessels. – For the re-crystallized white stains (long term stains), use dry polishing
before cleaning.– The grout lines and cracks need to be filled before high gloss treatment.– Long term maintenance can enhance the performance of the first
treatment.
Stone Treatment & Maintenance Proprietary and Confidential 29
Etching
• Causes– Every sort of stone has its specific ph value. – Many ingredients in stone can easily react with many acid/alkaline
material and leave etched stains, e.g., wines, soaps, shampoo…– Only stone professional cleaners can be used for daily cleaning.– Stone surfaces which need to contact wine, cleaners, shampoo, etc., need
acid/alkaline resistance treatment before use.
• Advices for treatment– Precise polishing to remove etched stains.– Infrared roasting to make the stone completely dry before sealing.– Sealing for water/oil/chemical resistance. The stone should have the
ability to resist red wine (ph=2.5) for at least 15 minutes.
Stone Treatment & Maintenance Proprietary and Confidential 30
Aging
• Causes– Flaking-off: Too much water penetrated into stone and damaged the
structure of stone.– Powdering: Too much water penetrated into stone and dissolved stone.– Gloss losing: UV light may cause aging. Water may dissolve the surface and
cause gloss losing. CO2, SO2, SO3 may react with the surface and cause gloss losing. Scratching, wearing…
– Cracks: expansibility on temperature. Impact. Water.
• Advices for treatment– Roasting can accelerate water under the stone vaporization. – Epoxy resins fillers should be weathering/ aging resistant.– Using water during polishing may is highly negative.– Allow the stone to breathe for a while before crystallization.
Stone Treatment & Maintenance Proprietary and Confidential 31
Mold
• Causes– Stone has vessels which can store water. – Under appropriate temperature, the stone located in murky corners may
allow mold, lichen, moss, and other plants to grow on the surface. – Some germs and plants will release some organic acid during growing,
which will etch the stone and cause gloss losing and even flaking off.
• Advices for treatment– Only stone professional mold removing cleaners can be used on the stone.– Rusts, water stains, and sometimes efflorescence are often coming
together with mold stains. – Heavy duty sealing after removing and cleaning.
Stone Treatment & Maintenance Proprietary and Confidential 32
Water Stains
• Causes– Granites can get water stains very easily. – The main ingredient of water stains is a sort of gelatine or gelatin, which
consists of hygroscopic silicic acid and saline-alkali material. – Some temporary water stains are caused by too much water in stone and
the water stains will disappear when the stone is getting drier. – The cement adhesives contains too much alkaline.– Too much water were used during installation. – The stone is too porous in a wet area. – The stone was cleaned by unprofessional acid/alkaline cleaners, which can
react with some oxides in cement and produce hygroscopic silicic acid and saline-alkali material. This can absorb water in stone and cause water stains.
• Advices for treatment– Heavy duty heating to accelerate water vaporization before treatment. – Use our stone professional technology to dissolve the gelatin.– Sealing for water and chemical resistance..– Or use color enhancer sealer to enhance the color of stone.
Stone Treatment & Maintenance Proprietary and Confidential 33
Oil Stains
• Causes– Stone in restaurants, on the square, and paver, will easily get oil stains
from food and gasoline.
• Advices for treatment– Some locally made cleaners will leave stubborn solvent stains after
removing oil stains.– For the indoor restaurant area, please check the sealers’ MSDS to see
whether they are environment friendly and allow food contact before use.
Stone Treatment & Maintenance Proprietary and Confidential 34
Colored Stains
• Causes– Tea, cola, sauce, inks, cosmetics, hair dye…may colorize the stone and
leave very deep penetrative stains.– Coatings, adhesives…will leave surface stains.
• Advices for treatment– Identify whether it is a waterborne or solvent borne pollution source. Use stone professional waterborne color remover to wet the stains for
some hours to see whether it can get lighter or not. Try many times till the stains disappear. Use stone professional oil stain remover to remove solvent borne stains
finally. – Estimate the depth of the stains in stone. For the deep stains, allow the cleaners to get longer time to penetrate into
stone. – For the coatings and adhesive, we recommend you to use our stone
professional coating remover only to avoid wrong material etching the stone.

The Concept of FSMA
The Full Service Maintenance Agreement (FSMA): The hotel purchases a certain period of our full service maintenance instead of buying stone treatment for each time to continuously maintain the cleanness, high gloss and high hardness of stone, which degrees have been indicated in the agreement.
•The hotel purchases a certain period of the “best looking” surface result of stone instead of just some treatments.•A period of regular maintenance is surely cheaper than the total amount of per-use costs during the period.•Irregular maintenance or surface treatment may result in huge costs during the operation of the hotel meanwhile hurt the stone. •Any re-installation or replacement will disturb the operation and finally increase the sales loss. •Any unprofessional cleaners, stone treatment material and processing will hurt the stone due to its specific chemical properties.
Stone Treatment & Maintenance Proprietary and Confidential 53
The Model of FSMA
• Identify technical basis of the “best looking” of the stone…– Understand the geochemistry and physical properties of the stone.– Determine the technical basis to match the daily operation. Cleanness Gloss degree Hardness degree– Determine regular maintenance schedule.
• Confirm a FSMA plan for a specific area with the hotel
• Programs– Regular crystallization treatment to improve hardness and gloss for the
floors Weekly based, e.g. for the reception area in the lobby Monthly based, e.g. for the restaurants and most of the PA. Seasonal or half-year based, e.g. for the guestrooms.– Regular problem solving and quality maintenance.– Regular quality check and immediate treatment when the data doesn’t
match the required index in the FSMA and this treatment will not quote to the hotel.
– Non-periodic visiting service and immediate response to the requirements of the hotel.
