Intercrete 4842 is an auxiliary. Intercrete 4842 has extremely high water penetration resistance, can withstand hydrostatic pressure up to 10 bar, and has excellent ability to block the penetration of carbon dioxide and chloride ions. A two-component, modified polymer, elastic cementitious coating for protecting cracked and displaced concrete and masonry structures. For auxiliary curing, Intercrete 4870 curing membrane must be applied directly over Intercrete 4842 for protection. Parameters on this page: volume solids 100% (the wet film thickness during application equals the dry film thickness after curing), dry film thickness 1000, number of components: two.

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 etc. need to be treated with suitable Intercrete series products. See the Intercrete 4842 application guide for more information.
The substrate needs to be thoroughly soaked with clean water until completely saturated. Remove excess water before applying Intercrete 4842.
All concrete floors, decks and highly porous substrates shall be sealed with Intercrete 4850.
| Mixing | Intercrete 4842 is a two-component coating, liquid binder (Part A) and powder component (Part B). Mix only the required amount. Thoroughly shake Part A and pour it into a suitable mixing container, then slowly add Part B while mechanically stirring. Mix for 5 minutes, cleaning the coating from the edges of the container during mixing to prevent lumps. For spray application, the mixed coating needs to be filtered through a 4 mm sieve. The mixed coating must be used up within its pot life. |
|---|---|
| Pot life | 30 min at 20 °C (68 °F) |
| Suitable for airless spray | Recommended nozzle tip size 1.275 mm (50 mils); paint pressure at the nozzle not less than 189 kg/cm² (2688 lb/in²). Recommended Graco 45:1 airless spray equipment |
| Brush | Recommended for small areas only |
| Thinner | Up to 0.5 L of clean water may be added per 30 kg |
| Cleaner | Clean water |
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. After |
| 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.
This product data sheet provides the general use of Intercrete 4842. Special project use needs to be designed according to the substrate condition, final use and environmental conditions. Consult International Protective Coatings before use to confirm whether Intercrete 4842 is suitable for the project.
Always follow the project system provided by International Protective Coatings.
Intercrete 4842 should always be protected from freezing during storage and transport. The recommended storage temperature is 4 °C (39 °F) to 25 °C (77 °F).
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
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).
The typical system for Intercrete 4842 is two coats, each 1000 µm (40 mils).
Intercrete 4842 is not designed to provide an aesthetic surface and may show a mottled appearance before full curing.
In cold, damp environments, the surface layer of Intercrete 4842 will darken and the curing time will be extended.
For auxiliary curing, Intercrete 4870 curing membrane must be applied directly over Intercrete 4842 for protection.
Intercrete 4842 can be used with sacrificial anode and impressed current cathodic protection systems.
Mechanical properties (typical values): compressive strength (BS 4551 @ 20 °C (68 °F)) 28 days 8–10 MPa; flexural strength (BS 4551 @ 20 °C (68 °F)) 28 days 3.5–4 MPa; extensibility in atmospheric environments 120–130%, in immersed environments 70–80%; water penetration resistance: 2 mm = 2270 mm ordinary concrete. Before use, refer to the Intercrete 4842 application guide.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Depending on the substrate condition and possible exposed reinforcement, additional Intercrete series surface treatment products may be required before applying Intercrete 4842.
All concrete surfaces need to be sealed with Intercrete 4850 before applying Intercrete 4842.
The following topcoat is recommended for use with Intercrete 4842: Intercrete 4870
