Sikadur®-43 HS
Epoxy resin mortar
Sikadur®-43 HS is a 3 parts repair and filling mortar based on a combination of epoxy resins and selected high strength aggregates.
- Rapid hardening
- Shrinkage-free hardening
- High mechanical strengths
- Hardens even at high humidity
- High resistance against abrasion, impact and vibration
- Can be applied onto dry and damp substrates (no standing water)
Usage
Sikadur®-43 HS is a high strength material that is used as bedding or underfilling mortar (dry pack) or to repair horizontal concrete surfaces, such as:- Industrial floors
- Kerbstones
- Bridge bearings
- Foundation slabs
- Crane rails
- Joint arrises in highways
- Concrete runways
- Industrial floors
- Abrasion and impact resistance wearing layers
Advantages
Sikadur®-43 HS is an economical material with the following beneficial properties:- Rapid hardening
- Shrinkage-free hardening
- High mechanical strengths
- Hardens even at high humidity
- High resistance against abrasion, impact and vibration
- Can be applied onto dry and damp substrates (no standing water)

SUBSTRATE QUALITY
All surfaces must be clean, free from oil, grease, old coatings, laitance, standing water and all loosely adhering particles. Sandblasting, high pressure water-jetting, grinding or scabbling of substrate is necessary.
SUBSTRATE PREPARATION
Prime with Sikadur®-732 for dry substrate. On damp substrates (no standing water) use Sikadur®-31 LP as primer, work well into substrate. Always work wet-on-wet on the bonding bridge/primer.
MIXING
Mix all of Part B (hardener) with all of Part A (resin) for at least 2 minutes with a slow speed electric drill (maximum 500 rpm) until a smooth consistency and streakfree colour is achieved.
Then add all of Part C (aggregates) and continue mixing until a homogeneous mortar is obtained. Use immediately.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened or cured material can only be mechanically removed.
