Technical Support Parchem offer a comprehensive range of high performance, high quality construction products. In addition, Parchem offer a technical support package to specifiers and contractors which includes on-site, technical advice from staff with unrivalled experience in the industry. Specification Clauses Where so designated, joints are to be sealed using a fuel resistant, pourable, elastomeric joint sealant confirming to BS5212:1990 type N, type F and type FB. The sealant must also conform to US Federal Specification SS-S-200F:1984. The joint sealant must be able to accommodate cyclic joint movement of up to ± 25%. Such a product is Colpor 200PF supplied by Parchem. Application Instructions Joint preparation Joint sealing slots should be accurately formed and must be dry, sound, clean and free from frost, curing compounds and form release agents. Remove all dust and laitance by grinding, grit blasting or wire brushing. The prepared sealing slot should be blown out with dry, oil-free compressed air. Ensure that any expansion joint filler fully fills the base of the joint and is at the required depth to provide the seal dimensions specified. Before sealing insert a polyethylene bond breaker tape into the base of the sealing groove to prevent sealant adhering to the base of the slot. Priming Prime joint sealing slot surfaces with Primer 7 and allow the surface to become touch dry before sealing. This takes between 30 minutes and 2 hours depending on climatic conditions. Colpor 200PF sealant must be applied within the time period of 30 minutes - 2 hours after priming before the primer film has completely reacted. After 2 hours any primed surfaces must be reprimed before applying sealant, therefore avoid priming more work than can be sealed in a 2 hour period. Avoid too liberal an application of Primer 7 causing puddles of primer to lie at the base of the sealing slot. Mixing Drain totally the contents of the tin containing the curing agent into the large base component tin. Using a slow speed drill (300 to 500 rpm) fitted with Mixing Paddle 315 ESAE (PC:770164), mix for approximately 1 minute, stop the mixer and scrape around the top of the tin to blend in any remaining curing agent. Continue mixing for a further 3 minutes until the material is thoroughly mixed. In cold weather, Colpor 200PF mixes more easily if stored overnight at room temperature. Application When mixed, the sealant may be applied in to the prepared joint using a Long Barrel ‘G’ Gun. In wider joints of 25 mm and above, the mixed sealant may be poured directly from the tin by bending the side to form a pouring lip. Apply mixed sealant into the sealing slot so that the finished level of the seal is recessed below the trafficked surface as specified. Finishing Release of air bubbles from joints with rough or porous faces will be will be enhanced by tooling the sealant surface with a convex tool. Tooling off will provide a smooth level finish. Any masking tape should be removed immediately after tooling. Cleaning Clean equipment immediately after use with Solvent 10. Remove mixed Colpor 200PF from the hands with an industrial hand cleanser. Limitations When sealing of floor joints indoors, the use of Thioflex 600 should also be considered in preference to Colpor 200PF due to some residual odour exhibited with Colpor 200PF. For situations where Colpor 200PF could come into contact with pavement asphalt, for example, a transition joint between concrete and asphalt pavements, apply two coats of Primer 7 to the asphalt joint faces. Allow the first coat to become tack-free before application of the second coat. Prime only those areas that can be sealed on the same day.
