Sikadur®-31 IN
Two-part thixotropic structural epoxy adhesive for dry and damp surfaces
Product Overview
Sikadur®-31 IN is a two-component, thixotropic structural epoxy adhesive based on epoxy resins and special fillers. Supplied as a grey paste that mixes 2:1 by weight, it is solvent-free, moisture-tolerant and non-sag, so it can be applied to vertical and overhead surfaces without slumping and bonds equally well to dry or damp concrete. It cures without shrinkage, needs no separate primer and remains impermeable to liquids and water vapour. Typical uses include bonding concrete, stone, masonry, steel, aluminium, timber and composites, plus repairing edges and holes, sealing cracks and filling joints. It serves structural repair, retrofitting and precast contractors. Space Arc Engineering offers Sikadur®-31 IN across India as an authorized Sika distributor, with application support for bonding and repair projects.
Features & Benefits
- Thixotropic, non-sag paste ideal for vertical and overhead bonding
- Bonds to both dry and damp concrete, widening the working window
- Strong adhesion to concrete, steel, stone, masonry, timber and composites
- Cures with no shrinkage and needs no separate primer coat
- Impermeable to liquids and water vapour for durable, sealed joints
- High structural strength with bond failure occurring in the concrete itself
Technical Highlights
| Coverage | Consumption is about 2.0 kg/m² per millimetre of layer thickness, up to a 30 mm maximum layer. |
| Strength | Compressive strength develops to about 60 N/mm² and tensile adhesion reaches over 10 N/mm² (concrete failure). |
| Performance | Pot life is at least 40 minutes for a 100 g mix at +30°C; cures without shrinkage. |
| Application Conditions | Apply with substrate, ambient and product temperatures between +10°C and +40°C, substrate at least 3°C above dew point. |
| Packaging | Grey paste in 3 kg, 6 kg and 30 kg pack options (2A:1B by weight). |
Applications
- Bonding steel plates and fixings during structural strengthening of beams
- Repairing spalled edges, corners and holes on bridge and building concrete
- Sealing cracks and filling rigid joints in industrial floors and structures
- Bonding precast concrete segments and stone cladding on commercial projects
- Fixing anchors and dowels in residential and renovation repair work

Frequently Asked Questions
What can Sikadur®-31 IN bond?
It bonds concrete, stone, ceramics, masonry, steel, aluminium, timber and composites, and is also used to repair edges, corners and holes, seal cracks and fill joints. As a thixotropic paste it suits vertical and overhead surfaces.
Can Sikadur®-31 IN be applied to damp concrete?
Yes. It is moisture-tolerant and bonds to both dry and damp concrete surfaces. No separate primer is required; just ensure the substrate is sound and at least 3°C above the dew point.
What is the mixing ratio and pot life?
Components are mixed 2:1 by weight (Part A to Part B). Pot life is at least 40 minutes for a 100 g mix at +30°C; warmer temperatures shorten working time, so mix only what can be used. Refer to the TDS for details.
What strength does Sikadur®-31 IN achieve?
Compressive strength develops to around 60 N/mm² and tensile adhesion to concrete exceeds 10 N/mm² with failure in the concrete, confirming a structural bond. Confirm exact values against the current TDS.
