Sikadur 32 LP is a moisture-tolerant, structural, two-part bonding agent based on epoxy resins and special fillers. It's designed with a longer pot life for use at higher temperatures (+20 °C to +40 °C). This versatile product offers excellent adhesion to various construction materials and provides high bond strength. Available from ProTrade Warehouse across Australia for experienced professionals.
Uses
Sikadur-32 LP is for experienced professionals and can be used for corrosion protection of reinforcement and as a structural bonding agent and adhesive for concrete elements (including bonding fresh to hardened concrete), hard natural stone, ceramics, fibre-cement, Monotop Repair Mortars, bricks, masonry, render, steel, iron, aluminium, wood, polyester/fibreglass, epoxy resin materials, and glass.

Important Considerations
- Consult a structural engineer for design calculations in structural applications due to creep behaviour of polymers under load. Long-term structural design load should be significantly lower than failure load.
- When using multiple units, mix the next unit only after the previous one has been used.
- Provide temporary support for heavy components positioned vertically or overhead.
ECOLOGY, HEALTH AND SAFETY
For information and advice on the safe handling, storage and disposal of chemical products, users shall refer to the most recent Safety Data Sheet (SDS).
APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY
Hardened mortar and concrete must be older than 28 days (depending on any minimal strength requirements). Verify the substrate strength by testing (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 to a condition similar to Sa 2.5. The substrate must be sound and all loose or friable particles must be removed.
SUBSTRATE PREPARATION
Concrete, mortar, stone and brick
Concrete and other hardened mineral substrates must be prepared by suitable means such as high pressure water jetting and / or blast cleaning, in order to obtain surfaces that are sound, clean, dry or mat damp (no standing water) and free from any cement laitance, ice, grease, oils, old coatings or other surface treatments. Any loose or friable particles must also be removed to achieve a contaminant free and open textured surface.
Steel
Steel surface must be cleaned and prepared thoroughly to an acceptable quality standard equivalent to Sa 2.5 i.e. normally by blast cleaning and then removing any dust by vacuum. Avoid dew point conditions.
MIXING
Pre-batched units:
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 grey colour. Avoid aeration while mixing. Then, pour the whole mix into a clean container and stir again for approx. 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.
APPLICATION METHOD / TOOLS
Apply the mixed Sikadur 32 LP to the prepared surface by brush, roller, spray or with a trowel, and ensure uniform and complete coverage. On hardened concrete substrates mechanically prepared to receive fresh concrete, always apply by brush and work the material well into the substrate.
Place the fresh concrete whilst the Sikadur 32 LP layer is still ‘tacky’. If the material becomes glossy and loses tackiness, apply a fresh coat with additional Sikadur®-32 LP and proceed.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with Sika Colma Cleaner immediately after use. Hardened material can only be mechanically removed.
