Product Overview
Sealing movement joints in building and civil engineering structures, including superstructures, reservoirs, floors, basements and subways.
Thioflex 600 is 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 surfaces including primed concrete, glass, aluminium and stainless steel. Thioflex 600 is available in gun and pouring grades. The gun grade is ideal for general application. It is packed in ready to mix, 2.5 litre & 4 litre tins containing the base and curing agent in the correct proportions. The pouring grade for joints in horizontal surfaces is supplied in 4 litre & 5 litre packs with the base and curing agent in separate tins. Both these grades are available in Grey colour only. For coloured sealants, Fosroc recommends the use of Nitoseal MS300* ‡ , a single component high performance silyl terminated polyether sealant, available in white, grey, black, portland, rustic red and brown. Thioflex 600 is particularly recommended for use in high rise buildings and other applications where access for subse- quent maintenance will be difficult and the risk of early movement failure must be minimised. It is also suitable for sealing joints in brickwork, retaining walls, reservoirs, basements and subways.Thioflex 600 pouring grade is recommended for sealing expansion joints and stress relief joints in floors or other horizontal surfaces. Specification Joints shall be sealed using Fosroc Thioflex 600, two part, polysulphide sealant, manufactured by Fosroc to BS 4254 1983, and ASTM C 920 -87. Joints shall be prepared and the sealant mixed and applied in accordance with the manufac- turer’s current data sheet.
Thioflex 600 may be applied to joints between 5 and 50 mm wide. Joints which are expected to experience cyclic move- ments 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, glass and other non-porous surfaces; 10 mm for all porous surfaces; 20 mm for trafficked joints and those subject to hydrostatic pressures. To ensure that the sealant remains within its stated move- ment capacity (25% MAF), sealing slot widths should be designed in accordance with the recommendations of BS 6093. The use of a surface primer is always required on porous surfaces. On non-porous surfaces a primer is not normally required except where glass or glazed surfaces are to be permanently immersed in water.

Applications
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 Fosroc Joint Cleaner. 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. Note: The use of a bond breaker is not required in expansion joints containing Fosroc Hydrocell XL* ‡ or Expancell* ‡ cellular polyethylene expansion joint fillers. For construction or contraction joints a bond breaker tape or back-up strip should be used. Where hydrostatic pressure exists, only bond breaking tapes must be used, not foamed back-up strips. Where a particularly neat finish is required, mask the face edges of the joint before priming and remove immediately after tooling is completed.

These are theoretical yields. No allowance has been made for variation in joint width or wastage. The mixed Thioflex 600 must be applied when the primer becomes tacky but not wet (typically between 5 - 20 minutes after application). If the primer dries, the joint surfaces must be re-primed before applying the sealant. Steel surfaces Iron and steel must be protected with an anti-corrosion primer prior to sealing.
Gun Grade The base component and curing agent are supplied ready for mixing in a single tin. Mix thoroughly using a slow speed drill (300-500 rpm) fitted with a Fosroc Mixing Paddle (MR2) 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. Immediately after mixing, load the sealant into a Fosroc ‘G’ Gun using the follower plate, and apply to the joint. Pouring Grade Thioflex 600 Pouring Grade is supplied in two separate containers. The small container contents should be transferred to the other tin, and mixed as per the gun grade instructions. The pouring grade may be poured directly into horizontal joints or for application to horizontal joints less than 15 mm wide loaded into a Fosroc ‘G’ Gun. For quantity application, a Fosroc 1.5 litre gun is available. Finishing Thioflex 600 should be tooled to a smooth finish. A minimum of surface lubricant such as dilute detergent solution may be used to assist the process. Any masking tape should be removed immediately after tooling.
