A two-component, water-borne, modified polymer cementitious anti-corrosion mortar.
Designed as part of the Intercrete concrete repair system to rapidly restore the passivation layer around reinforcing steel and provide long-term corrosion protection.
Typical application procedure: brush application of two coats in quick succession, each 1 mm thick.
| Colour | Grey, INTERCRETE 4871 |
|---|---|
| Gloss | Matt |
| Volume Solids | 100% (the wet film thickness at application equals the cured dry film thickness) |
| Typical thickness | Apply two coats, each 1000 µm (40 mil) |
| Theoretical Spreading Rate | At typical thickness, each 5 kg covers a total of 45 m of 10 mm reinforcing steel. |
| Practical Spreading Rate | Allowing for a suitable loss factor |
| Density | 1800 kg/m³ (112.369 lb/ft³) |
| Application Methods | Drying Time and Recoat Interval for Brush Application |
| Temperature | Surface Dry | Hard Dry | Minimum | Maximum |
| 20°C (68°F) | 5 h | 18 h¹ | 45 min | 7 days² |
¹ Data for application at 1000 µm (40 mil), may vary with climatic conditions. ² If the recoat interval exceeds the maximum self-recoat interval, the surface must be thoroughly abraded and wetted before application of the subsequent coat. Intercrete concrete repair mortar may be applied 2–6 h after completion of the thickest coat of Intercrete 4871.

| Volatile Organic Compounds | 0 g/L calculated value. For further details, see the Product Characteristics section |
Reinforcing steel surface
| All surfaces to be coated must be clean and free of contamination. Before application, all surfaces must be assessed and prepared in accordance with ISO 8504:2000. | Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard. |
|---|
Blast cleaning
| Surface preparation to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6. | Surface defects exposed during blasting must be ground, filled or treated by a suitable method. |
|---|
Recommended angular surface roughness of 75–100 µm (3–4 mils).
Hand or power tool preparation: hand or power cleaning to at least St3 (ISO 8501-1:2007) or SSPC-SP2.
Use this method only when abrasive blasting is not possible due to environmental factors. Surrounding concrete shall be chloride-free.
Surfaces prepared by hand or power tool cleaning shall be coated as soon as possible. The interval between completion of surface preparation and start of application shall not exceed 24 h.
Intercrete 4871 may be applied to damp steel substrates from which excess water has been removed.
| Mixing | Intercrete 4871 is a two-component product: a liquid binder component (Component A) and a powder component (Component B). Shake Component A thoroughly and pour into a suitable mixing container. Then add Component B slowly under mechanical stirring. Mix for 5 min, scraping the container walls to prevent lump formation. The mixed coating shall be used within its pot life. |
|---|
For small-area repairs, mix with the supplied tool for 2–3 min to a fluid, lump-free consistency. Use the recommended mixing ratio.
Do not add water or other substances.
| Mixing ratio | 1 part : 3 parts (by volume) |
|---|---|
| Pot life | 20°C (68°F) 60 min |
| Brush | Recommended | For small areas only |
| Thinner | Do not thin | |
| Cleaner | Clean water | |
| Interruption of work | Clean all equipment thoroughly with clean water. | To prevent the paint from drying, seal the product container promptly after use. |
| Cleaning | Clean all equipment immediately after use with clean water. |
|---|
All surplus material and empty containers must be disposed of in accordance with the appropriate local laws/regulations.
Consult the Intercrete 4871 application instructions before use.
