Faircrete 17 is a silicate based clear liquid densifier when applied on concrete surfaces penetrates into the micro channels and seals against water and chemical attack and improves abrasion resistance.


• Superior in performance over Sodium based systems
• Seals micro-channels in concrete against water penetration and chemical attack.
• Hardens – making concrete stronger and abrasion resistant.
• Dust proofs-creating a cleaner, healthier environment.
• Permanent – One penetrating application.
• Easy maintenance. Makes cleaning easier. Reduces staining.
• Satin sheen to concrete.

Recommended Uses

FAIRCRETE 17 is used for surface hardening of new and old concrete to prevent dust generation and to reduce wear, particularly on exposed concrete. Typical areas of application include warehouses, factories, platforms, car parks, corridors etc., on both new and existing concrete surfaces.

Application Instructions

Surface Preparation:
The substrate shall be thoroughly cleaned of all foreign materials such as bond breakers, curing agents, form release oils, dust, construction laitance by light mechanical grinding if required. Clean the surface with a high pH detergent and wash thoroughly. The surface shall be saturated with water and later excess water has to be removed.


A low pressure, high volume sprayer shall be used to apply FAIRCRETE 17 so as to form a glistening sheen and to ensure complete saturation of the surface. Enough FAIRCRETE 17 shall be applied to keep the surface wet for at least 20 minutes.

If applying by hand, spread the sprayed material with a lambs wool roller once or twice and then stop spreading. If spread excessively, it tends to dry in streaks. After 20 minutes, the excess material shall be removed and the surface shall be allowed to dry for 1 – 2 hrs. The floor is ready to use after the surface is dry. A light lithium residue may form on the surface after the floor is dry. This is the excess FAIRCRETE 17 liquid floor hardener which was not absorbed and can be removed by a stiff broom or power sweeper. For an immediate shine, FAIRCRETE 17 shall be allowed to dry overnight and then polished with a high speed buffer equipped with a black pad, followed by a red pad.

Sealing / Overcoating / Striping:

The treated surface can also be painted for striping as there will be no chemical incompatibility between FAIRCRETE 17 treated surface and these paints.


Floors treated with FAIRCRETE 17 benefits from good routine maintenance. Regular scrubbing with a high pH detergent is recommended and can increase the shine. Tyre marks can be removed with a citrus type of cleaner. Oils and acids should be removed properly to prevent damage.

Packing and Coverage

Packing : FAIRCRETE 17 is supplied in 20 & 200 ltr containers.
Coverage : Spray applied – 10 – 12m² per Ltr on power trowelled surfaces. On textured surfaces the coverage will be much lower.



FAIRMATE supplied the concrete admixtures and other products for the precast and insitu concrete works on this structure, and now we develop a high strength epoxy resin adhesive system, to bond the joints between the precast concrete segments.

The Successful combination of new pre-stressing systems with new assembly equipment led to the development of the precast segmental construction method for bridges. The most important first developments were probably in 1940s, and it is now used by many of engineers, contractors, equipment producers and manufacturers around the world.
It has become established and used successfully on numerous large projects, including many of the world’s most important recent bridge structures.


FAIRBOND CS (S) & FAIRBOND CS (W) has been used extensively for a segmental bridge bonding construction applications, the need became clear for a specific range of segmental bridge adhesive which could meet the different and increasingly precise requirements of bridge designs and at the different working temperatures which occur during their construction periods. These included application in daytime temperatures of up to 45°C, curing during very low and cold night time temperatures, plus the rapid erection cycles demanded for the precast segments.

The FAIRBOND CS (S) & FAIRBOND CS (W) were the result – a range of adhesives, optimized for the specific technical requirements, suitable for use on the most challenging bridge projects. This is based on a reactive hardening epoxy binder system, with optimized filler granulometries, so that the products support the continuously optimized production process of segmental bridge construction.

The Fairbond CS (S) & Fairbond CS (W) (segmental bridge adhesive) range, which fully complies with FIP and AASTHO standards, but also to be able to meet the specific requirements of each construction site.

The application and characteristics of segmental bridge bonding products must be carefully matched so that the adhesive can meet the following requirements:

• To bond the surfaces so that compressive and shear forces also the tensile forces can be safely convey from to every bridge segment.
• To lubricate the joint faces between the segments to make them easier to finally position together during their installation.
• To seal the joints between the segments against future ingress of water and de-icing salts etc,i.e. to protect the prestressing cables against corrosion.


In order to meet all these requirements under the different site application conditions, including variable temperatures/ moisture contents/ mixing and application methods etc., the epoxy adhesive must have carefully selected precisely defined characteristics and test methods to confirm these.

The table below contains the main criteria covered by “International Federation of Prestressing” FIP (now developed as fib “Federation international de beton) and AASTHO (American Association Of State Highway and Transportation Officials), which have also shown the FAIRBOND CS products specification.

Purposes of Epoxy

The purposes of using an epoxy resin in the joint between the segments are:

• To maintain the structural integrity of the joint and maintain a monolithic concrete segment
• To completely fill any minor surface imperfections and irregularities between the match cast surfaces
• To provide a water and grout tight seal, preventing chloride intrusion
• To act as a lubricant when erecting the segment
• To ensure tight fit between the segments so that the compressive and shear stresses are transmitted directly across the joint


Epoxy comes in two part compounds consisting of a resin and hardener. When mixed together, they begin curing which can take anywhere from a few minute to a few hours, depending on the formulation, the site and storage temperature and the mass of the epoxy, The cure time will be shorter when epoxies are mixed in higher temperature conditions and in larger masses.

Segmental bridge epoxies are specially formulated as either normal or slow setting resins. For Segment by segment erection, the normal set epoxies are used and for span by span erection, the slow set epoxies are used. It is important to use the correct pot life and correct temperature range to ensure good working time and proper strength gain of the epoxy.

Surface preparation:

Concrete should be mechanically sound and free form contamination such free water, mould oil, grease, laitance or dust. A dry grit blasting on the surface is recommended for optimum adhesion. Sections to be checked for good alignment. A ‘dry run’ before the first application of the adhesive is recommended to ensure correct timing.


The contents of hardener should be added in to the base and mixed for 2-3 minutes with a paddle attached slow speed heavy duty drill. It should be ensured that the sides and base of the can is thoroughly scrapped down. A uniform grey colour should be obtained after homogenous mixing.


The mixed adhesive should be applied at required thickness to both laying surfaces with a serrate trowel or other suitable spreader. The joint should be closed immediately. If this is not achieved the surface of the adhesive should be slightly scratched immediately prior to closing the joint to be exposed fresh adhesive. The joint must be closed within the open time of the adhesive. On site monitoring of the operation using lapped asbestos cement panels is recommended.

When the segments are brought together and stressed, excess epoxy is squeezed out. For joints over traffic or water, procedures must be implemented to avoid dropping below. Once the segments has been joined and stressed, all excess epoxy should be cleaned. If leaving it to harden will make it more difficult to remove later on.

Tools and equipment should be using SAFECORE TOOL CLEANER immediate after use.
