SEALANT

GUN GRADE TWO PART POLYSULPHIDE SEALANT

Polysulphide sealant is design to seal joints subject to movement, where a tough flexible watertight seal is required. FAIRSEAL has Excellent weathering characteristics with resistance to rain, snow, heat & ultraviolet light.
FAIRSEAL is a two-part joint sealant based on liquid polysulphide polymer. It is based on liquid polysulphide polymer. When mixed and cured, the sealant exhibits excellent adhesion to most surfaces including concrete, glass aluminum & stainless steel. FAIRSEAL is suitable for sealing vertical joints only. FAIRSEAL has superior joint movement accommodation with strong adhesion to most building materials. It is chemically resistant to water, oils, solvents, etc.
FAIRSEAL may be applied to joints between 5 to 50 mm width / depth. Minimum joint depths are 5mm for metal, glass, and another non-porous surface. 10mm for all porous surfaces like brick and concrete. 20 mm for trafficked joints and those subject to hydrostatic pressure.

SALIENT FEATURES OF POLYSULPHIDE SEALANT,
• Quick curing with low shrinkage
• Accommodates continuous and pronounced cyclic movement
• High resistance to ageing influences, physical damage and climatic extremes
• Resistance to petrol, diesel, jet fuel and most other common solvents & also unaffected by mild acids and alkalis.

APPLICATION

SURFACE PREPARATION: Before the application of the sealant, all joint surfaces should be thoroughly cleaned and dried, and primed with FAIRSEAL PRIMER. Loose particles, dirt, dust, protective liquor, oil and grease should be remove by vigorous brush with a wire brush and by means of suitable cleaners e.g. KEROSENE. After the primer is applied, it has to be relatively dried before sealant is applied.

MIXING: FAIRSEAL sealant supplied as base and hardener (curing agent) in separate packing, ready for mixing. In order to mix both the compounds thoroughly, it is preferable to use a slow speed electric mixer with suitable blades or paddles with speed < 300 RPM. Make certain that mixing till a uniform color is obtained. Failure of sealant when it is not completely and thoroughly mixed.

FAIRSEAL is used for sealing expansion joints between structures in building construction like infill panels, metal finishes and in civil engineering structures like basements, buildings, walls, and brickwork joints, etc. FAIRSEAL is suitable for sealing vertical joints only. It is quick curing with low shrinkage. It is unaffected by mild acids, alkalis, & resistance to petrol, diesel, jet fuel, etc.

FINISHING: To obtain smooth surface, the sealant has to be tooled by drawing a flat tool, like a stainless steel spatula over its surface.
ESTIMATION OF QUANTITY
Formula: Weight in Kg = (1.6 X W X D X L)/1000
Where W & D are in mm and L is in metre,
Example
W (Width of joint) = 10 mm
D (Depth of joint) = 10 mm
L (Length of joint) = 12.5 mtr
Weight in Kg = (1.6 X 10 X 10 X 12.5) / 1000 =2kg of sealant
PACKING
FAIRSEAL is available in big packing of (4.6kg base + 0.4kg hardener) & small packing of (0.920kg base + 0.08kg hardener).
FAIRSEAL is highly inflammable & it must be stored away from heat & kept in dry condition.

POURABLE GRADE TWO PART POLYSULPHIDE SEALANT

FAIRSEAL P is a two-part, pourable, self-leveling, polysulphide-based joint sealing compound consisting of the base compound containing a liquid polysulphide polymer and the second part being an accelerator containing a curing agent. After mixing, the compound cures to form a tough, rubber-like material with excellent flexibility and outstanding resistance to weathering water, salts, oils, mild alkalis, etc.
FAIRSEAL P is suitable for sealing horizontal joints due to its pouring consistency. It has excellent adhesion to most surfaces including concrete, wood, glass, aluminum, and stainless steel. For all porous surfaces like concrete wood, FAIRSEAL PRIMER is necessary.
FAIRSEAL P may be applied to joints between 5 to 50 mm width/depth. Minimum joint depths are 5mm for metal, glass, and other non-porous surfaces. 10mm for all porous surfaces like brickwork and concrete.

APPLICATION

SURFACE PREPARATION: Before the application of the sealant, all joint surfaces should be thoroughly cleaned and dried, and primed with FAIRSEAL PRIMER. Loose particles, dirt, dust, protective liquor, oil, and grease should be removed by vigorous brushing with a wire brush and utilizing suitable cleaners e.g. KEROSENE. After the primer is applied, it has to be relatively dried before a sealant is applied.
MIXING: FAIRSEAL P sealant is supply as base and hardener (curing agent) in separate packing, ready for mixing. To mix both the compounds thoroughly, it is preferable to use a slow-speed electric mixer with suitable blades or paddles with a speed of < 300 RPM. Ensure thorough mixing till a uniform color is obtained. Failure of sealant will often occur if it is not completely and thoroughly mixed. After mixing FAIRSEAL P may be poured directly into horizontal joints or loaded into the gun for application to horizontal joints less than 15mm wide.

FAIRSEAL P is suitable for sealing horizontal structure expansion joints like building superstructures, subways, basements, floors, PQC roads, airport runways, and reservoirs. It is a pourable grade sealant for horizontal joints. It is a tough elastic rubber-like seal. It is unaffected by mild acids, alkalies, & resistance to petrol, diesel, jet fuel, etc. It gets cured quickly with low shrinkage.

FINISHING: To obtain smooth surface, the sealant has to be tooled by drawing a flat tool, like a stainless steel spatula, over its surface.

JOINT SIZE
FAIRSEAL P may be applied to joints between 5 and 50mm. Minimum 5mm. depth is recommended for metals, glass and other smooth surfaces while minimum 10mm depth is recommended for concrete and brickwork surfaces. The use of a greater depth is recommended where resistance to external pressure is required, e.g. joints in floors and hydraulic structures. Ideally joints subject to regular movement should be designed with a width/depth ratio of 2:1.APPLICATION PROCEDURE

Surface Preparation
All joint surfaces should be thoroughly cleaned and dried and primed with ‘FAIRSEAL PRIMER’. Loose particles, dirt, dust, protective liquor, oil and grease should be removed by vigorous brushing with a wire brush and by means of suitable cleaners e.g. KEROSENE. After the primer is applied, it has to be relatively dried before sealant is applied. Deep joints should be back filled with a non retting backup material to which the sealant does not adhere eg. Closed cell polyurethane foam, which should be tampered into the joint to the required depth.

Application
FAIRSEAL P sealant is supplied in a pack with base and hardener (curing agent) in separate packing, ready for mixing. In order to mix both the compounds thoroughly it is preferable to use a slow speed electric mixer with suitable blades or paddles with a speed less than 300 RPM. Ensure thorough mixing till a uniform color is obtained. Failure of the sealant will often occur if it is not completely and thoroughly mixed. After mixing FAIRSEAL P may be poured directly into horizontal joints or loaded into the gun for application to horizontal joints less than 15mm wide.

Tooling & Finishing : To obtain a smooth surface, the sealant has to be tooled by drawing a flat tool, like a stainless steel spatula, over its surface. After sealing, the tools and equipments must be cleaned with KEROSENE.

ESTIMATION OF QUANTITY
To estimate quantities of sealant required, the formula given below can be used to calculate the number of (1 Kg or 5 Kg) tins needed. To calculate the weight (in Kg.) of sealant required for a joint of particular length (in meters), the following formula can be used.

Formula: Weight in Kg = (1.6 X W X D X L)/1000
Where W & D are in mm and L is in metre,
Example
W (Width of joint) = 10 mm
D (Depth of joint) = 10 mm
L (Length of joint) = 12.5 mtr

Weight in Kg
= (1.6 X 10 X 10 X 12.5)/1000 = 2 kg of sealant

1 Litre of FAIRSEAL Primer would cover 6 to 7 m² of joint area or about 1 litre of FAIRSEAL Primer would be required for 30 Kg of FAIRSEAL sealant.

PACKING
FAIRSEAL P is available in big packing of (4.600 kg base + 0.400 kg hardener) and small packing of (0.920 kg base + 0.080 kg hardener).
