ARCAFLEX FLEXIBLE JOINT MORTAR adheres excellently to all building materials and masonry materials such as: cement, steel and pvc substrates but also adhere on tile!
- In basement walls,
- Wall to floor joints,
- Swimming pools
Can be applied on:
- Concrete, cement
- Metal, steel,
- Ceramic tiles,
- PVC
ARCAFLEX is often used with ARCACEM S2 (see Application "protection")
Tools
Trowel, mixing paddle, pneumatic pump. Clean tools with water immediately after use.
Product Preparation
- Mix the 2 components in equal proportions (in terms of weight)
- Pour the component B into component A and stir with a trowel or an electric mixer until a homogeous paste is obtained.
Surface Preparation
The substrate must be, brushed clean and free of any loose material, dust and any loose particles which will prevent proper adhesion: laitance, separating agents, etc.
The surface must be clean and cohesive.
Wash and vacuum out cracks and joints.
Place a backing foam at the bottom of the joint.
Do not use in the presence of running water (major leaks).
Application
- Widen the crack using a chisel and hammer to a minimum of 2x 4cm and break away any deteriorating concrete (the edges of the crack should be vertical or beveled in an inverted “v”).
- Note: The width of the crack should be twice as large as the depth. See illustration below.
- Once the crack has a wider base, clean thoroughly using a wire brush, a damp cloth or a vacuum to remove small particles that will prevent the adhesive from bonding to the concrete surface.
- Prepare the product as indicated above
- Insert and pack down the flexible mortar to fill the entire area.
- Level off with a wet trowel

Drying Time
Once mixed use within: 3 hours (paste life)
Curing time: 1 to 10 days*
*Note: The product will dry quickly; full curing time will depend on the size of the area being treated, the porosity of the substrate and relative humidity.
Protection
Arcaflex cannot be left alone and has to be overlied with a render or a tanking system. We recommend to apply our tanking system ARCACEM S2 with the reinforcement mesh ARCAFIBER. This tanking system can be left bare or covered with tiles, stones or a paint.
Recommendations
- Do not apply if the temperature is <5°C or >30°C
- Do not apply on frozen substrates or freezing is forecast within 48 hours of the application.
- Do not apply under hot dry sun.
N° cm² of the joint section X N° linear metres X 0.140kg
Exemple:
5 metres cracks (4cm width and 2cm depth = 8cm²)
5x8x0.140= 5.6 kg
5.6kg of Arcaflex is needed = 3x2kg
10 metres cracks (4cm width and 2cm depth = 8cm²)
10x8x0.140= 11.2 kg
11.2kg of Arcaflex is needed = 1x 10kg + 1x2kg
A 10kg tub will treat approximately 8 linear meters (section 8cm²)
Store Arcaflex in dry, cool and frost free conditions. Shelf life is 12 months if unopened.
