Uses

• Exterior and interior dilatation joints in concrete
• Exterior and sealing joints in almost all building substrates
• Joints between wooden, metal, aluminum or PVC frames and masonry

Advantages

• Very easy application
• Low modulus
• Stays elastic after curing
• Excellent adhesion to most building substrates
• Paintable (prior compatibility tests is necessary)
• First rate resistance to water and UV – Rays

Method of use Surface preparation

• Joint walls must be sound, clean, dry, 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-CS51 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-CS51 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-CS51 deeper than what is recommended can cause bubbling or incomplete curing of the material.
• Minimum depth: 6mm
• Maximum depth: 15mm
• Minimum width: 6mm
• Maximum width: 30mm

 Limitations

• Use only at temperatures above 4°c
• Avoid exposure to high levels of chlorine
• Avoid contact with alcohol and other solvent cleaners during cure
• Do not cure in the presence of curing silicone sealant
• Do not apply in or damp joints, as this can cause bubbling within the sealant
