FARCOFLEX HR

Uses

• Movement and connection joints in floors of ware- houses and production Ares, pedestrian and traffic areas, parking decks, car parks, and filling- stations.
• Expansion and sealing joints on surfaces in the food industry.
• Joint in waste water and sewerage treatment plants, filtration and aeration tanks.

Advantages

• Indoor and outdoor applications
• Suitable for all climates
• Less solvent content
• Movement capacity 25%
• Good adhesion to most construction materials
• Fungicide
• None yellowing and none bubbling
• Very good mechanical and chemical resistant
• Abrasion resistant
• Resist permanent deformation

Method of Use Surface preparation

• Joint walls must be sound, clean, dry, and free from oil and grease. Curing compound residues and any other foreign matter must be thoroughly removed, install bond breaker to prevent bond at the base of joint.
• Priming is not usually necessary. Most substrates only require priming if testing indicates a need or where sealant will be subjected to water immersion after cure.
• New concrete must be minimum of 28 days old. Substrates must be dry; application in wet or damp joints will cause bubbling of the material.

Mixing

FARCOFLEX–HR is one component and requires no pre-blending. It should be used directly from the container.

Application

For good performance, it is essential that the sealant is only bonded to the two facing sides of the joint to achieve this, install a backup material (closed cell polyethylene or open cell polyurethane foam).

Apply the sealant in a continuous operation, making sure all air pockets or voids are eliminated. Tool the sealant with light pressure to spread the material against the joint surfaces.

This operation should be made with dry spatula before skin formation occurs.

Cleaning

Material: Immediately with solvent

Hardened sealant: can only be removed mechanically

Hands: soap and water

Curing

FARCOFLEX–HR requires no special curing

Joint Dimensions

Joint width should be 4 times the expected joint movement, the depth of the sealant should be ½ the width of the joint. The maximum depth is 15 mm. Installation of FARCOFLEX–HR deeper than what is recommended can cause bubbling or in complete curing of the material.

Minimum depth: 6mm

Minimum width: 6mm

Maximum width: 30mm

Limitations

• Limited adhesion without primer on Copper, UPVC, PMMA, and polycarbonate.
• Do not use to seal swimming pools, on bituminous substrates, natural rubber, EPDM.
• Do not apply in or damp joints, as this can cause bubbling within the sealant.
