Advantages „ Forms a tough, elastic, rubber-like seal „ Accommodates continuous and pronounced cyclic movement „ Excellent adhesion to most common substrates „ High resistance to ageing reduces physical damage due to climatic extremes Description A multi-component joint sealant, based on a liquid polysulphide polymer, which when mixed and applied, cures to form a tough, rubber-like seal. The cured sealant exhibits excellent adhesion to most primed surfaces including concrete, aluminium and stainless steel. Thioflex 600 Pouring Grade for joints in horizontal surfaces is supplied in grey colour only in 4 and 16 litre packs with the base and curing agent in separate tins. Thioflex 600 Pouring Grade is recommended for sealing expansion joints and stress relief joints in floors or other horizontal surfaces. Design criteria Thioflex 600 Pouring Grade may be applied to joints between 5 and 50 mm wide. Joints which are expected to experience cyclic movements should be designed to an optimum width:depth ratio of 2:1, subject to the overriding recommended minimum sealant depths set out below: • 5 mm for metals and other non-porous surfaces; • 10 mm for all porous surfaces; • 20 mm for trafficable joints and those subject to hydrostatic pressures. All joints subject to repeated movement should be designed and spaced so that the total movement in tension and compression does not exceed 50% of the joint width at the time of sealing. Total movement in shear should not exceed 50% of joint width at the time of sealing. All movement joints shall be recessed 2 mm below flush so that during joint contraction the sealant does not protrude above the surface and so become susceptible to damage from traffic.
