Sikadur®-43 HE (h)
Three-part thixotropic epoxy mortar for high-strength patch repair and void filling
Product Overview
Sikadur-43 HE (h) is a three-part, thixotropic epoxy patch-repair and filling mortar based on epoxy resins and selected fillers. Its non-sag consistency lets it be applied in vertical and overhead locations, while its tolerance of damp substrates makes it practical for real-world repair conditions. It is used to repair and reprofile concrete, natural stone, ceramics, fibre cement, masonry, steel and other surfaces, and to fill cavities, voids and cracks where a high-strength, water-impermeable patch is required. Once cured it develops high compressive and flexural strength with good adhesion, abrasion and chemical resistance, and generally needs no separate primer. It serves repair contractors, precast yards and maintenance teams. Space Arc Engineering, an authorized Sika distributor in India, supplies Sikadur-43 HE (h) for structural concrete repair and patching projects.
Features & Benefits
- Non-sag, thixotropic consistency for vertical and overhead patch repairs
- Can be applied to damp substrates, widening the working window on site
- High compressive and flexural strength for durable structural patching
- Strong adhesion to concrete, stone, steel, masonry and more, usually without a primer
- Water-impermeable and chemically resistant once fully cured
- Pre-batched three-part unit for consistent, error-resistant mixing
Technical Highlights
| Coverage | Consumption is approximately 2.2 kg/m per millimetre of applied thickness; maximum layer thickness about 50 mm. |
| Strength | High strength: compressive strength up to around 108 N/mm at 14 days, flexural tensile up to about 25 N/mm (at +30 C). |
| Performance | Thixotropic, non-sag epoxy with good abrasion and chemical resistance; pot life about 35 minutes at +30 C. |
| Application Conditions | Apply at +5 C to +40 C for ambient, substrate and product; suitable for damp (not wet) surfaces. |
| Packaging | Supplied as a 25.2 kg pre-batched three-part (A+B+C) unit; mixed colour grey. |
Applications
- Structural patch repair of spalled concrete columns and beams in infrastructure
- Reprofiling damaged precast concrete elements in manufacturing yards
- Filling voids, pockets and honeycombing in cast concrete on industrial projects

Frequently Asked Questions
Can Sikadur-43 HE (h) be applied overhead and on damp concrete?
Yes. It is thixotropic and non-sag, so it can be worked in vertical and overhead positions, and it is formulated to cure on damp substrates. The surface should be damp rather than running wet, refer to TDS.
How strong is Sikadur-43 HE (h)?
It develops high strength, with compressive strength reaching around 108 N/mm at 14 days and flexural tensile strength up to about 25 N/mm at +30 C, making it suitable for structural patch repair.
How much Sikadur-43 HE (h) do I need?
Consumption is roughly 2.2 kg per square metre for each millimetre of thickness, applied up to about 50 mm in one layer. Estimate from the area and depth of the repair.
Does it need a primer?
In most cases no separate primer is required because of its strong adhesion to sound, prepared substrates. Always follow the surface-preparation guidance in the TDS.
