Sika Sikadur 41 CF Rapid is a moisture tolerant, thixotropic, structural 2-component adhesive and repair mortar.
Sika Sikadur 41 CF Rapid is formulated as a repair and bonding mortar for concrete elements, hard natural stone, ceramics, fibre cement, mortar, bricks, masonry, steel, iron, aluminium, wood, polyester, epoxy, and glass.
Sika Sikadur 41 CF Rapid is also suitable as a repair mortar for filling of cavities and voids, vertical and overhead use, corners and edges. 41 CF Rapid is also usable as an abrasion and impact resistant wearing course for joint filling and crack sealing and joint and crack arris / edge repair.
- Easy to mix and apply
- Very good adhesion to most construction materials
- High strength adhesive
- Thixotropic: non-sag in vertical and overhead applications
- Hardens without shrinkage
- Different coloured components (for mixing control)
- No primer needed
- High initial and ultimate mechanical strength
- Good abrasion resistance
- Impermeable to liquids and water vapour
- Good chemical resistance
Mortar and concrete must be older than 28 days (depends on minimal requirement of strengths). Verify the substrate strength (concrete, masonry, natural stone). The substrate surface (all types) must be clean, dry or mat damp (no standing water) and free from contaminants such as dirt, oil, grease, existing surface treatments and coatings etc. Steel substrates must be de-rusted similar to Sa 2.5. The substrate must be sound and all loose particles must be removed.
Concrete, mortar, stone, bricks:
Substrates must be sound, dry or mat damp (no standing water), clean and free from laitance, ice, grease, oils, old surface treatments or coatings and all loose or
friable particles must be removed to achieve a laitance and contaminant free, open textured surface.
Must be cleaned and prepared thoroughly to an acceptable quality i.e. by blast-cleaning and vacuum. Avoid dew point conditions.
Mix components A+B together for at least 3 minutes with a mixing spindle attached to a slow speed electric drill (max. 300 rpm) until the material becomes smooth in consistency and a uniform colour. Then add component C and continue until mixture is homogeneous. Avoid aeration while mixing. The, pour the whole mix into a clean container and stir again for ~ 1 more minute at low speed to keep air entrapment at a minimum. Mix only that quantity which can be used within its pot life.
Brush the adhesive well into the substrate. Sikadur®-31 CF can be used as primer to improve the bond. When using a thin layer adhesive, apply the mixed adhesive
to the prepared surface with a spatula, trowel, notched trowel, (or with hands protected by gloves). When applying as a repair mortar use some form work. When using for bonding metal profiles onto vertical surfaces, support and press uniformly using props for at least 12 hours, depending on the thickness applied (not more than 5 mm) and the room temperature. Once hardened check the adhesion by tapping with a hammer.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
Customer further agrees that Promain have no liability for any errors or omissions contained within the Product Data Sheets and are not liable for failure due to misapplication or inadequate substrate cleaning and preparation. For more information please refer to our Terms & Conditions.
