Specification Clauses Joints shall be sealed using Thioflex 600 Pouring Grade, two part, sealant, manufactured by Parchem. Joints shall be prepared and the sealant mixed and applied in accordance with the manufacturer’s current Technical Data Sheet. Application Instructions Joint Preparation The joint surfaces must be thoroughly dry, clean and frost free. Remove all dust and laitance by rigorous wire brushing, grinding or grit blasting. Remove all rust, scale and protective lacquers from metal surfaces. Remove any oil or grease with Solvent 10. Any expansion joint filler must be checked to ensure it is tightly packed and no gaps or voids exist at the base of the sealing slot before positioning a bond breaker tape. Note: the use of a bond breaker tape is not required in expansion joints containing polyethylene foam joint fillers. For construction or contraction joints polyethylene bond breaker tape or back-up strip must be used. Where a particularly neat finish is required, mask the face edges of the joint before priming and remove immediately after tooling is completed. Priming 3ULPHUFor use on metals and ceramics. It is a onecomponent INDEX 378 chemically active clear liquid for brush or pad application. One thin coat should be applied and allowed to dry for a minimum of 5 minutes prior to sealant application. 3ULPHU It is a one-component chemically active straw coloured liquid for brush application to concrete, stone, brickwork, timber and unglazed edges of ceramic tiles. Apply an even coat of Primer 7 to the bonding faces of the joint. Excessively porous surfaces may need more than one coat – this is evident where applied primer does not give a smooth, glossy surface when dry. Allow final coat to become touch dry (approx. 1 hour) before application of Thioflex 600 Pouring Grade. Any primed areas not sealed within 8 hours of primer application will need to be re-primed 1 hour prior to sealant application. Important for all primers Avoid over priming resulting in an excess of primer in the base of the joint or application beyond faces. 7KHPLHG 7KLRIOHPXVWEHDSSOLHGZKHQWKHSULPHULVWDFN IUHH, that is after the evaporation of the solvent but before the primer film has completely reacted. If joints are not sealed within 8 hours of primer application, they must be re-primed and allowed to become touch dry as previously stated. Mixing Thioflex 600 Pouring Grade is supplied as a Base component (in a larger tin) and Curing Agent component which is either 1 x 300ml cartridge for the 4 litre unit, or 4 x 300ml cartridges for the 16 litre unit. Transfer ALL of the Curing Agent component/s into the larger tin. Mix thoroughly using a slow speed drill (300-500 rpm) fitted with a Paddle Stirrer for 5 minutes. Only thorough mixing, including material right at the bottom of the tin, will result in proper curing. In cold weather Thioflex 600 mixes more easily if stored overnight at room temperature. The pouring grade may be poured directly into horizontal joints. For application to horizontal joints less than 15 mm wide load into a suitable gun. Finishing Note: Thioflex 600 Pouring Grade is NOT a ‘self levelling’ material. Release of air bubbles from joints with rough or porous faces will be enhanced by tooling the sealant surface with a convex tool. Any masking tape should be removed immediately after tooling. Cleaning Clean equipment immediately after use with Solvent 10. Cured sealant can only be removed mechanically or after soaking in Solvent 10. Contract application The designer or contractor may wish to use the services of a specialist sub-contractor for joint sealing work. Names of preferred sub-contractors are available from Parchem. Limitations Over-painting of sealants is not recommended because of the inability of paint films to accept movement. However, if required, trials should be carried out to determine compatibility.
