Description
Sikadur®-32 LP is a moisture tolerant, structural, two part bonding agent, based on a combination of epoxy resins and special fillers, designed with a longer potlife or working time for use at higher temperatures, between +20 °C and +40 °C.
USES
As a corrosion protection to reinforcement as per EN1504.
- Suitable for cathodic control (Principle 9, method 9.1 EN 1504-9)
- Suitable for control of anodic areas (Principle 11, method 11.2 EN 1504-9)
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 and epoxy resin materials
- Glass

18 lt (A & B) kit
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 potlife.
