The importance of premix mortar in present days is inevitable. Depending on the type of products we are dividing it 4 categories
a) Readymade Plaster
b) Block Jointing Mortar
c) Cementitious Tile Adhesive
d) Cementitious Underlayment
A. Readymade Plaster
Plaster is a mineral coating with protective and decorative functions. Plaster is applied at a thickness that can vary from a few millimetres to a few centimetres, for the purpose of levelling off masonry surfaces in order to make them even. The widespread use of this type of coating is due to the fact that it is economical, quick to prepare and easy to apply. Since it was first introduced at the end of the nineteenth century, plaster has been subjected to substantial variations regarding both its composition and its function. Initially the so-called “gauged” mortars (a mixture of lime, cement and sand) were formulated, while from the second half of the twentieth century the ready-made, “pre-mixed” plasters started to be developed.
Readymade plasters are ready-made, powder compounds consisting of binders, aggregates and additives which serve to improve both the performance and the laying of the product. Once water has been added, they are ready for use. The majority of plasters produced using ready-made mortars require the application of a plaster undercoat and a skim or finishing plaster. In the choice of the various types of material, it is of fundamental importance to ensure compatibility among the various product types. The composition of the mix may vary depending on the type of application – by hand or by machine – and according to the coats and thicknesses to be applied.
The name of our readymade plaster is Readyplast which is available in 25 kg and 40kg bags and one 40 kg bag can cover approx 15 sqft at the thickness of 15mm.
B. Block Jointing Mortar
AAC blocks is a new kind of building materials which has heat preservation, thermal insulation, sound insulation, light weight, fire prevention and so on. It is a very ideal wall material simultaneously with high heat preservation and good surrounding protection function and is only one able to satisfy 65% energy savings index and has good developing prospects. However, AAC blocks is a silicate materials with very porous structure, the porosity reaches 70~80%. If the mortar usage and job practice are unsuitable, cracking and leaking in wall, hollowing and spalling in plastering layer and other quality defects are often rise, which affects seriously the application of AAC blocks.
For jointing those blocks the mortar should have excellent workability, good water retention high cohesiveness, small shrinkage. Mortar joint thickness is only 3~5mm and much smaller than that of traditional construction (level joint about 15mm, vertical joint about 20mm), not only saving raw materials but also facilitating the manage and construction. Furthermore, Block Jointing Mortar could reach a high wall-construction quality for its excellent workability, good water retention, higher cohesiveness and high crack resistance. It avoids piling up massive raw material in job location, reduces environment influence, especially in building face-lifting and improvement project in big or medium cities. Besides, the AAC blocks needn’t to sprinkle before building into wall, which can save water.
The reasons of mortar quality defects cause by traditional construction
AAC block is a porous silicate material with many internal isolated pores. The pores can be divided into “bubble pores” and “micro pores”. “Bubble pores” are formed from gas-forming reaction of aluminum powder, its majority shape is like “ink bottle”. “Micro pores” includes “gel pores” and ” capillary pores” forming from the evaporation of water, most of them exist in wall between bubble pores. Although all these pores make AAC blocks having high porosity from 70% to 80%, most of the pores are isolated one another, interconnected pores are little, many capillary pores are separated by the bubble pores, so the capillary action is weak; as a result, the absorption of water by AAC blocks is rather slow resource and avoid sewage pollute the job site, facilitating civilized production.
The pore structure and slow absorbent property of AAC blocks lead it to have a characteristic of “water could not pour through”. Therefore, relevant regulations require the AAC blocks for “twice wetting”: firstly wetting AAC blocks at 1 or 2 days before construction, secondly wetting at about an hour before construction. But, it is difficult to make AAC blocks absorbing enough water in practice. If a mortar with poor water retention and bad workability is used in this case, AAC blocks will constantly absorb the water from mortar, so that the mortar cannot fully hydrate and produce enough amount of cementing products, as a result, compressive strength and bond strength of the mortar cannot reach engineering requirements and widespread cracks and leaks in wall, hollowing and spalling in plaster layer and other defects would rise.
We have eco friendly sand free block jointing mortar named Readyplast Block Bond Powder which is available in 5kg & 25 kg pack size.
C. Cementitious Tile Adhesive
From the early beginnings until the middle of last century cement based mortar p.e tilling mortar prepared by basically mixing cement, sand and water in the appropriate ratio by hand at the jobsite. The quality of the site-mixed mortar depended on the quality of the raw materials and on the correct batching ratio which could not be controlled easily. However in 1950 s two major innovations revolutionized tiling mortar technology.
The first revolution was the development of redispersible polymer powder. Polymers are added to cementitious tile adhesive in order to improve their elasticity and bonding to the substrate with the tiles. The advent of this technology enabled to produce polymer modified dry mix adhesive.
The second revolution was the improvement of the substrates. Due to modern plaster and dry construction technologies substrate got more and more even. Therefore the thick bed mortar was required to level the substrate for laying tiles were necessary.
We have 3 categories of cementitious tile adhesives
Fairfix Mortar: It is general purpose tile adhesive and conforms to IS 15477 : 2004, ANSI A118.1-1999 & Type C1 of EN 12004. It is available both grey & white colour.
Fairfix TA STD: It is medium quality tile adhesive and conforms to IS 15477 : 2004 and C2TE of ISO 13007. It is available both grey & white colour.
Fairfix TA Ultra: It is very high quality tile adhesive and conforms to IS 15477: 2004 and C2TESI of ISO 13007. It is available both grey and white colour.
D. Cementitious Underlayment
Laying a concrete floor slab or floor screed over a fairly large area lends itself to a little inaccuracy simply because of the difficulty in moving and laying an extremely wet and heavy material like concrete.
Traditional methods of leveling and repairing concrete floors are both labor intensive and require the use of screeds, trowels and sanders that are less than desirable because of site mixing, waves, cracks, etc. Self-leveling products have a variety of advantages over trowelable underlayment.
The flooring industry has always placed a strong emphasis on smooth and level concrete surfaces upon which to install resilient flooring. With today’s large amount of commercial remodeling/renovation projects, the attempts to reduce costs in the new construction market and the declining availability of competent cement finishers, you need a product that help to solve most problems related to floor leveling and repair. Fortunately, modern self-leveling cements provide you with solutions that are technically sound and cost effective.
Fairmate has very economical self-leveling cementitious screed named “Fairfix Underlayment Screed” which is having the following benefits.
• Prepack and ready to use
• Fast setting
• Foot traffic after 4 hours
• High Early strength
• Outstanding resistance to cracking
• Application thickness is 20mm to 50mm
It is available in 25kg and 40kg bag.

Coverage : A 5 Kg pack is sufficient to prime 25 m² of surface.
We must remember that no other surface in a building takes more abuse than floors, regardless of the type of building, be it industrial or commercial. While a bare concrete floor can withstand tremendous weight and pressure, it is relatively porous and susceptibility to significant damage when left untreated or uncoated. If exposed to regular foot traffic or the demands of a commercial environment, concrete will readily absorb dirt, chemicals, oils and other spillages. This often results in stains, cracks and abrasions that can make the floor impossible to clean and unattractive in appearance. Hence all concrete floors need some sort of protection regardless of where they are located. Over the last few years, the protection of concrete floors has gone from essentially nothing to a fairly sophisticated process of some type of protective coating or surfacing. The main purpose is to provide protection to the slab from deterioration or contamination or to provide some added benefits such as aesthetics, wear, non skid, chemical resistance, ease of maintenance and different other properties. How to choose the protective material for concrete floor in different conditions?
Whether you are constructing a new concrete floor or revamping an old one, there are different coatings you can choose to finish the project. We are focusing on coatings that are bonded directly to the surface and offer long term protection and may or may not have some aesthetic value.
Typical coatings that are mostly used for concrete floors include polyurethane & epoxy.
Polyurethane (PU) flooring has some added advantages over epoxy flooring which are as follows.
a) Flexible in nature
b) UV resistant
d) Slip resistant
e) Abrasion resistant
f) Scratch resistant
g) Higher temperature resistant

It can also be suitable for use in car parking and light to medium engineering operations.
The preparation of the concrete is of vital importance for the effective use of this product. Concrete must be firm, hard and free from old coatings, concrete laitance and any contaminants which may impair adhesion. The concrete must have a profiled textured surface, which can be achieved by captive shot blasting, grinding or milling. For areas, which are contaminated by oil and grease, HCA (Hot compressed air) treatment may be
required. All dust and debris must be vacuumed away to leave a clean and dust free surface.
Priming is required and undertaken with FAIRCRETE SB(L) – an acrylic primer. Apply two coats of primer by roller, brush or spray. Apply the primer to the prepared surface and allow drying. (Normally overnight). For the second coat, dilute one part FAIRCRETE SB(L) to three parts water and apply to the previous coat. Allow to become touch dry before application of FAIRTOP FAST FLOOR MICRO.
FAIRTOP FAST FLOOR MICRO is mixed applied by specialist mixer /pump. Measure 3.6 liters cool, potable water, into a suitable sized mixing vessel and mix full bag of FAIRTOP FAST FLOOR MICRO. Mix the composition for 3 to 5 mins. until a homogenous mix is observed. Mixing shall be carried out with a slow speed drill (400-500 RPM) fitted to a paddle attachment.
Pour the material, immediately after completion of mixing, on the dry, primed surface, spread with a trowel and allow to ‘self level’. The required thickness of 2-3mm must be achieved in one application, for better durability a sealer coat of SAFECORE PUD should be applied which increases abrasion. For best results, the pouring and leveling should be a continuous process. If complete flooring is to be done, material pouring shall be started from dead end. (From the farthest end of entry / exit location).
Note: If the mix stiffens, it should be discarded. Do not attempt to re-mix with water.
In normal conditions, FAIRTOP FAST FLOOR MICRO does not require curing, but in harsh climatic conditions of direct sunlight, drying winds etc., freshly hardened surfaces should be covered completely with a polythene sheet for 2 days.
Packing and Coverage
FAIRTOP FAST FLOOR MICRO is available in 18 kg HDPE bag. Coverage will be 1.8 kg/m² at 1mm thickness.

Concrete floor can truly result in an incredibly beautiful floor where unlimited self expression can be reached. Limited in industries till new, it is growing in popularity as more homeowners realize the fantastic benefits of concrete floors. Additionally, new processes and technologies have been developed to make concrete one of the most affordable and versatile flooring materials.
JUSTIFICATION FOR USE OF CONCRETE FLOOR COATING
We must remember that no other surface in a building takes more abuse than floors, regardless of the type of building, be it industrial or commercial. While a bare concrete floor can with stand tremendous weight and pressure, it is relatively porous and susceptibility to significant damage when left untreated or uncoated. If exposed to regular foot traffic or the demands of a commercial environment, concrete will readily absorb dirt, chemicals, oils and other spillages. This often results in stains, cracks and abrasions that can make the floor impossible to clean and unattractive in appearance. Hence all concrete floors need some sort of protection regardless of where they are located. Over the last few years, the protection of concrete floors has gone from essentially nothing to a fairly sophisticated process of some type of protective coating or surfacing. The main purpose is to provide protection to the slab from deterioration or contamination or to provide some added benefits such as aesthetics, wear, non skid, chemical resistance, ease of maintenance and different other properties. How to choose the protective material for concrete floor in different conditions? Whether you are constructing a new concrete floor or revamping an old one, there are different coatings you can choose to finish the project. We are focusing on coatings that are bonded directly to the surface and offer long term protection and may or may not have some aesthetic value. Typical coatings that are mostly used for concrete floors include acrylics, polyurethane, epoxy, or specialized elastomeric liquid membrane coating etc. However, before applying any new coatings to your floor just make sure that the ingredients are free from any chemical reactions that can cause significant damage to the floors. Industrial epoxy floor coatings are beneficial in order to maintain a safe, durable concrete surface besides proving it with a new and improved look.
The first step in the selection process is to evaluate the existing surface to determine what you are working with. The surface must be structurally sound, clean and must not be contaminated with any foreign material that could interfere with the bond of a new coating system. This includes concrete curing compounds.
Other critical things to consider are: is the surface distressed in any way? Does it have cracks, spills, or unevenness? Does the coating system required a level floor or one that slopes to a drain? What type of surface preparation is needed for the area in question? It is the most important step in the installation process and is critical to long-term performance of the total system.
Chemical exposure: Severity of the exposure and types of chemicals are both very important. Materials differ widely in chemical resistance, making identifying the exposure very important. Common splash and spills also are far less critical than constant immersion.
Abrasion: The amount of wear or traffic on a surface will make important criteria. Are there steel wheel or rubber wheel.
FAIRMATE | In technical collaboration with M/s. RBP Ltd. UK 3
Impact and Thermal shock: Heavy loads and direct impact require a heavier build or thicker floor system. Temperature fluctuation or thermal shock, such as steam cleaning of the floor surface, will cause a loss of bond from thermal expansion if the floor system is not chosen properly.
Economy is the top requirement. At times, low cost systems will prevail at the expense of more durable systems. Generally when other parameters are exhausted, you get what you pay for. Another generally accepted rule is that the thicker the applied system, the better the performance.
APPLICATION AND POST APPLICATION
Once the surface has been leveled the material must be applied and the job inspected and approved. The choice of an appropriate contractor to install the system is just as important as the material used. A contractor trained to install a particular system. The job does not end with the application of material. A long term review, maintenance and repair programme. Should be established for continued performance and satisfaction. Post application, even the most durable surface might show areas of distress in future that may require attention. A small amount of attention before installation will prolong the life of a flooring system. The whole project is to create a low maintenance situation, so spending more money on the best materials and the extra time spent on preparation time is well worth it.
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.
