Intercrete 4841 polymer-modified cementitious mortar coating belongs to Auxiliary. Intercrete 4841 has extremely low water permeability, can withstand positive and negative hydrostatic heads up to 10 bar, and also has good resistance to carbon dioxide and chloride ion attack. It is a two-component, thixotropic, polymer-modified cementitious mortar coating suitable for anticorrosive protection of concrete substrates. To assist curing, Intercrete 4870 curing protective film is required, applied directly onto Intercrete 4841 for protection. Parameters on this page: volume solids 100% (wet film thickness during application equals dry film thickness after curing), number of components two-component.

This is a two-component, thixotropic, polymer-modified cementitious mortar coating suitable for anticorrosive protection of concrete substrates.
This product is designed as a structural waterproofing and anticorrosive layer to protect concrete substrates, with good chemical resistance and abrasion resistance. Intercrete 4841 can use Intercrete 4872 as reinforcement to resist cracking and movement at joints.
Intercrete 4841 has extremely low water permeability, can withstand positive and negative hydrostatic heads up to 10 bar, and also has good resistance to carbon dioxide and chloride ion attack.
Intercrete 4841 is the ideal product for increasing reinforcement coverage.
Is a product listed under DWI Regulation 31 suitable for contact with potable water.

Concrete substrates: all surfaces to be treated shall be clean and free of curing agents, release agents, smoothing compounds, surface hardeners, efflorescence, grease, oil, old coatings and loose or disintegrating concrete. Recommended surface preparation is wet blasting or water jetting.
After surface preparation, all surface defects such as holes, small and large voids and other defects shall be treated with appropriate products from the Intercrete range. Refer to the Intercrete 4841 application instructions for more information.
The substrate shall be thoroughly soaked with clean water until fully saturated. Remove excess standing water before applying Intercrete 4841. All concrete floors, decks and highly permeable substrates shall be sealed with Intercrete 4850.
| Mixing | Intercrete 4841 is a two-component coating. Liquid binder (Part A) and powder component (Part B). Mix only the quantity required. Thoroughly shake Part A, pour into a suitable mixing container, then slowly add Part B while mechanically stirring. Mix for 5 min, scraping the sides of the container during mixing to prevent lump formation. For spray application, the mixed coating shall be filtered through a 4 mm sieve. The mixed coating shall be used within the pot life. |
|---|---|
| Pot life | 30 min at 20 °C (68 °F) |
| Suitable for airless spray | Recommended tip size 1.40 mm (55 mil) paint pressure at nozzle not less than 189 kg/cm² (2688 psi) |
| Brush | Recommended — for small areas only |
| Thinner | Do not thin |
| Cleaner | Clean water |
| Interruption of work | Do not allow coating to remain in the hose, spray gun or spray equipment. Thoroughly flush all equipment with clean water; organic solvents shall not be used. |
| Cleaning | Clean all equipment immediately after use with clean water. Flushing spray equipment periodically during application is recommended. Cleaning frequency depends on the volume sprayed, temperature and time, including all interruptions. |
Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.
Before use, the Intercrete 4841 application instructions shall be consulted.
This product data sheet provides general methods of use for Intercrete 4841. Use on specific projects shall be designed according to substrate condition, end use and environmental conditions. Consult International Protective Coatings before use to confirm the suitability of Intercrete 4841 for the project.
Always follow the project system provided by International Protective Coatings.
Intercrete 4841 shall always be protected from freezing during storage and transport. Recommended storage temperature is 4 °C (39 °F) to 25 °C (77 °F).
This product does not cure adequately below 5 °C (41 °F) ambient. For best results, curing should take place between 10 °C (50 °F) and 35 °C (95 °F).
Typical scheme for Intercrete 4841 is two coats at 1000 µm (40 mil) each. When applied to floors, decks and tidal zones, Intercrete 4840 single coat at 2000 µm (80 mil) is recommended.
Intercrete 4841 is not designed to provide an aesthetic finish and may exhibit a patchy appearance before full cure.
In cold, damp conditions, the surface of Intercrete 4841 will darken and curing time will be extended.
To assist curing, Intercrete 4870 curing membrane shall be applied directly onto Intercrete 4841 for protection.
Mechanical properties (typical values) Compressive strength (BS 4551 @ 20 °C (68 °F)) 1 day 10.5 MPa 7 days 30.5 MPa 28 days 40.0 MPa Water permeability: 2 mm = 6000 mm ordinary concrete (2 mm = air equivalent thickness R = 5200 m) Note: VOC value is typical and for guidance only. This value may vary with factors such as colour differences and normal manufacturing tolerances.
Concrete substrates may require additional surface preparation products from the Intercrete range before application of Intercrete 4841, depending on substrate condition and possible exposure of reinforcing steel. For details, consult International Industrial Coatings.
All concrete floors, decks and highly porous substrates shall be sealed with Intercrete 4850.
