Polysulphide Sealant

A TWO COMPONENT POLYSULPHIDE SEALANT SPECIFICATION BS 4254 ; BS 5212 ; ASTM C 920 DESCRIPTION Perma Polyseal is a two part polysulphide sealant based on polysulphide resin, curing agents, select fillers, plasticisers and vulcanizing agents. When the base and curing agents are mixed it forms a uniform color mass which can either be poured on to the horizontal expansion joints or gunned into the vertical joint depending upon the grade. Essentially Perma Polyseal is available in two grades. Pour grade for horizontal application and gun grade for non slump vertical applications. Perma Polyseal PRIMARY USES Perma Polyseal is an expansion joint sealant useful in sealing horizontal as well as vertical joints. Perma Polyseal is used for sealing reappearing cracks on the roofs, shear cracks in the brickworks and joints in water tanks. Perma Polyseal is used for sealing gaps between the building material of different structures such as concrete and wood, glass and aluminum, and exterior glazings. Perma Poly seal is used in expansion joints varying between 6 mm to 50 mm. ADVANTAGES Perma Polyseal seals the joints and makes them watertight. Perma Polyseal accommodates the movement of structures because of expansion contraction and also because of deflections and settlements. Perma Polyseal is tough hence floor joints treated with Polysulphide can be trafficable. Perma Polyseal when dry gives an aesthetic smooth grey appearance. Perma Polyseal is resistant to chemical spillages and also resistant to Oils, Petrol, Diesel and Solvents. DIRECTIONS FOR USE SURFACE PREPARATION: All joints to be sealed with Perma Polyseal should be dry, clean and free from any dirt, dust, rust, scale or any protective lacquer or grease. Expansion joint fill material (bitumen impregnated board) shall be tightly packed in position so that a clear joint depth as per joint design is available. As a thumb rule depth of joint is taken as half of its width and the depth is not less than 6 mm. A bond-breaking tape or cello tape is fixed on the joint fill board to avoid direct contact between Perma Polyseal and the Board. Apply masking tape on top surface on either side of the joint to avoid staining of neighbouring area. PRIMING: If the sides of the joints are porous and irregular use Polysulphide primer which is a two component material. Mix the two components and brush apply on the sides of the joint. When the primer becomes tack free apply or pour Perma Polyseal in the joint. MIXING: Transfer the entire contents of the small curing agent pack to the larger pack of the base and mix thoroughly for five minutes by electric drill with blades or manually till a uniform consistency paste is obtained. APPLICATION: Pour the mixed Perma Polyseal in the joints and finish the joints using rounded spatula or similar object to bring about a smooth surface and also remove any air which might have got entrapped during mixing. It is advisable to finish the surface slightly concave to keep the Perma Polyseal unaffected by heavy trolley movements.
