Description  

Sikaflex-11 FC+ is a one-component polyurethane adhesive and joint sealant for internal and external building work. Designed for flexible, non-structural bonding and sealing, it combines adhesion to compatible construction materials with ±35% movement capability in correctly designed joints.

Multipurpose bonding and joint sealing

Use Sikaflex-11 FC+ to bond suitable concrete, masonry, ceramic, timber and metal components, or to seal vertical and horizontal construction joints. It is also suitable for selected glass-bonding applications where the bond line is not exposed to sunlight. The cured seal is elastic, pick resistant and suitable for exposed building joints. Stone substrates require advice from Sika before use.

Before you apply

Apply to clean, sound and dry substrates, following the manufacturer's guidance for preparation and primers. Use mechanical fixings for overhead or heavy components. Do not use for structural bonding, glass or sanitary joint sealing, trafficked floor joints, permanent immersion or swimming-pool joints. Avoid bitumen, natural rubber, EPDM, polyethylene, polypropylene and PTFE; keep alcohol-containing products away from uncured material.

For dedicated concrete and masonry façade movement joints, compare Sikaflex PRO.

Common Questions  

How much movement can Sikaflex 11 FC+ accommodate?
It is rated for ±35% joint movement to ASTM C 719.

Can Sikaflex 11 FC+ be used as an adhesive?
Yes. It is designed for flexible bonding as well as joint sealing.

Can it be used around swimming pools?
No. Do not use it in or around pools, under water pressure or for permanent immersion.

Can it be used for structural bonding?
No. The product guidance excludes structural bonding applications.

Uses & Benefits  
One-component polyurethane adhesive and sealant for flexible bonding and movement joints in concrete, masonry, stone, ceramics, timber, metal and glass. Accommodates ±35% joint movement to ASTM C 719. Suitable for internal and external construction work. Cure rate is about 3.5mm per 24 hours at 23°C and 50% relative humidity. Very low VOC at less than 1g/L.
How To Apply  
Use on clean, dry, sound substrates. For concrete, brick and cement render in demanding applications use Sika Primer-3 N. For aluminium, stainless steel, galvanised steel and glazed tile, lightly abrade where required and use Sika Aktivator-205. For copper, brass, bronze and titanium-zinc use Sika Aktivator-205 followed by Sika Primer-3 N. PVC uses Sika Primer-215. For bonding, apply triangular beads, strips or spots and position components before skin formation. For sealing, use closed-cell polyethylene backing rod, extrude continuously and tool firmly against both joint faces. Clean uncured material with Sika Remover-208. Cured material requires mechanical removal.
Limitations and Safety Info  
Do not use on bituminous substrates, natural rubber, EPDM, PE, PP, PTFE or materials that leach oils, plasticisers or solvents. Do not use in or around swimming pools, under water pressure, for permanent immersion, or for sanitary joints. Do not use to seal glass windows or bond glass where the bond line is exposed to sunlight. Do not use for structural bonding or trafficked floor joints. Avoid full-surface adhesive applications where the inner layer cannot access moisture to cure. Use mechanical fixings for overhead or exceptionally heavy components. Do not expose uncured sealant to alcohol-containing products.
Suitable Substrates  
  • Concrete and masonry.
  • Reconstituted, cast and natural stone subject to Sika technical guidance.
  • Ceramics, glass and timber.
  • Anodised aluminium, stainless steel, galvanised steel, copper, brass and bronze.
