POLYURETHANE BASED TOUGH ELASTOMERIC WATERPROOFING MEMBRANE
Waterguard PU Liquid Membrane is a pitch extended polyurethane based elastomeric coating, formulated to give long lasting, maintenance free, and superior waterproofing protection for concrete and steel structures.
Chemical resistant: Resists deterioration from dilute acids and alkali, oil, salts, bacteria, and common fuels.
Single component, Easy to apply.
Applied by roller, brush, or airless spray.
Tenacious adhesion and high elastic recovery.
Long term resistance to ponded water.
High elongation, permits membrane to stretch with movement in the substrate.
Excellent crack bridging properties.
Continuous monolithic (seamless) layer completely bonded to the substrate, eliminates horizontal migration of water between membrane and the substrate. Thus if the membrane is punctured, a leak can only occur directly below the damaged section of the membrane, allowing fast location and inexpensive repairs.
Waterguard PU Liquid Membrane is used as a waterproofing or vapor barrier for protection of Foundations & Basement, Ground floors, Kitchens & bathrooms, Split slab, Terraces, balconies & patios, Car Park decks, Inverted roofs & sunken slabs, Tunnels.
Surface must be structurally sound, clean dry and free from dust, grease, curing compounds, paint coatings, and other loose debris. Surface should ideally have a “sand paper” profile roughness. Recommended methods for preparing concrete are by sand or captive shot blasting; wire brushing or by pneumatic (scabbling) tools. Shrinkage and non structural cracks should be pre-treated with a 1mm thick coating of WATERGUARD PU LIQUID MEMBRANE reinforced with WATERGUARD GRS – fiber reinforce sheet extending at least 50mm on both sides of the crack. Allow to cure for 24 hours. Right angle or corner should have cant strips installed. A suitable cant strip can be prepared by mixing 1 part cement and 1 part fine clean sand and FAIRCRETE FBR additive. First apply 0.5mm thick WATERGUARD PU LIQUID MEMBRANE on the corners. Embed a 100mm width reinforcing WATERGUARD GRS – fiber reinforce sheet on the bedding coat then apply a second coat of WATERGUARD PU LIQUID MEMBRANE 0.5mm thick completely covering the reinforcement. Allow to cure at least 12 – 24 hours. Install mortar canting on the corners extending on both sides by 50mm. Allow cure for 24 hours prior to general application.
Normally WATERGUARD PU LIQUID MEMBRANE can be applied directly onto the surface and does not require priming.
The product requires thorough mixing (for at least 3 – 5 minutes) with a mechanical drill (300-400 rpm) fitted with a proprietor paddle prior to application so that a homogenous mix is achieved. Application should commence as soon as product mixing is completed. Apply the coating at 1.2 kg/m²/coat to achieve a dry film thickness of 1000 microns. The coating can be applied in either one or two coats. If applying in two coats ensure that the second coat is applied only after the first coat has become tack free. The second coat is recommended to be applied in the opposite direction to the first coat as this will allow the polyurethane in the mix to be distributed more uniformly. The coating will achieve its full mechanical properties after a period of 7 days.
HIGH PERFORMANCE HARDENER, STRENGTHENER AND DENSIFIER FOR CONCRETE FLOOR
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.
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.
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.
SEGMENTAL CONCRETE BRIDGE BONDING
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 PRODUCTS – SEGMENTAL BRIDGE BONDING
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.
THE PERFORMANCE REQUIREMENTS
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.

EPOXY JOINTING ADHESIVE
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
TYPES AND APPLICATION OF EPOXY
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.
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.

Apply thin bond coat to the substrate with the straight edge of the trowel. Then comb mortar on to the fresh bond coat with the notched edge of the trowel working in the direction. Apply only that much mortar which can cover the tiles within the open time. Open time can be checked by touching the adhesive bed with fingertip.
Position tiles in the adhesive bed and align with a slightly pushing motion, ensuring the tile back achieves full contact with the adhesive.
Remove excess adhesive with a damp cloth before material has set. Joint grouting may be commenced24 hours after tiles have been laid.
Environment friendly protective and Decorative coating for interiors and Exteriors
THE BASIS OF ECO FRIENDLY PAINTS
Natural ingredients are at the heart of the unique qualities of FAIRCOAT E-GREEN. The binder is liquid silicate whose structural form and hardness is perfectly compatible with its inorganic colorants and the inorganic concrete and masonry structures it is applied to.
The principle strength of silicate paints is their penetration within the substrate. This results in a solid mineral and insoluble compound of paint and substrate (concrete, natural stone, marble, etc). The cross-section through the render shows this penetration, which is also known as silification. This chemical bond locks the paints into the subsurface as opposed to organic coatings that sit on the surface.
FACTORS AFFECTING PENETRATION DEPTH
While penetration depth may not be critical for many architectural applications, greater penetration will have a significant effect on strength and durability of applications on cement based substrates, porous stone and traffic bearing surfaces. Penetration depth is influenced by the substrate’s pore structure and permeability, moisture content and surface preparation.
When FAIRCOAT E-GREEN is applied to suitable substrates, it penetrates and reacts to form a hard, insoluble silicate. It can also increase substrate hardness, particularly in cementitious materials. When applied to materials containing Portland cement, the silicate reacts with incompletely hydrated cement particles, converting unreacted calcium hydroxide (CaOH2 or hydrated lime) to harder calcium silicate hydrates.
WATER VAPOUR PERMEABILITY
The high water vapour permeability of silicate paints is due to their crystalline nature which ensures that humidity present in the masonry can freely pass from the substrate. Thus water cannot build up between the paint and the substrate – which normally leads to paint cracking/ blistering and being pushed off the surface. Instead, the substrate remains dry and the breathability of the building is maintained.
FAIRCOAT E-GREEN do not burn, unlike emulsion and other organic based paints. In the event of a fire breaking out, damage to the substrate is reduced and the paint does not give off any toxic fumes.
NO FUNGUS, ALGAE OR MOLD
The pure inorganic inert composition and high pH of silicate paints prevents any fungi, algae or mold growth, thus assuring a hygenic and clean paint layer. The absence of surface condensation due to the coatings high water vapor permeability, promotes a clean, healthy environment. Traditional organic paints provide smooth film coatings that do not breathe, attract moisture and fungi, algae and mold spores. Toxic mold growth is the number one health problem in building structures today. FAIRCOAT E-GREEN can improve the health of the building environment.
REGULATION OF TEMPERATURE
Silicate paints have a micro-crystalline structure, which reflects lightand heat. In hot climates this reflective property reduces the thermalstress on the structure and reduces the amount of cracking the substratewould normally undergo.
Neither harsh climates nor high UV radiation can alter the color of a FAIRCOAT E-GREEN Redecoration in the same color shade is possible after many years. Traditional organic paint coatings are subject to UV deterioration from day one, breaking down the paint film which changes the color and causes the coating to fail. Silicate paints have an extremely long life providing important economies over the long term.
This water based Silicate paints are harmless to the environment, consisting of natural mineral compounds including quartz, inorganic mineral colorants and liquid silicate used as a binder. Silicate paints represent a technology which has no detrimental effects on the environment in terms of manufacturing as well as in terms of application. Under fire conditions no toxic fumes evolve as the FAIRCOAT E-GREEN does not ignite.
Thus FAIRCOAT E-GREEN is Breathable, Moisture Resistant, Does not contribute to growth of mold, algae or mildew, Durable and UV Resistant; does not yellow, fade or peel.
