Intercrete 4820 Waterproof Coating Filler is an auxiliary. This product is designed as a waterproof coating filler for small-area pores and defects, providing a suitable surface for subsequent application of the Intercrete concrete protection system. A single-component, fibre-reinforced waterproof smoothing or levelling coating. During flat surface application, before the final coat cures, trowel marks may be removed with a trowel or wet sponge to obtain a sandpaper-like surface. Parameters on this page: volume solids 100%, number of components single-component. Comparable models from the same brand: Ceilcote 6650 Ceilcrete, Intercrete 4841 Polymer-modified Cement Mortar Coating, Intercrete 4842.

¹ For multi-coat systems, it is essential to ensure that the previous coat has been applied with a wooden or plastic trowel and that the surface has not fully cured before application of the subsequent coat.
² If the recoat interval exceeds the maximum recoat interval, the surface must be thoroughly abraded and wetted before application of the subsequent coat.

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.
Voids and pores of various sizes exposed during surface preparation must be repaired with suitable Intercrete products. All damaged areas must be restored. For further information, refer to the Intercrete 4820 application instructions.
The substrate must be thoroughly soaked with clean water until fully saturated. Remove excess standing water before application of Intercrete 4820.
The concrete substrate must have a minimum strength of 20 MPa before application.
| Mixing | Intercrete 4820 is a single-component powder. Pour 3 L of clean water into a mixing container, then add 25 kg of Intercrete 4820. Mix with a low-speed mixer; the maximum permitted mixing speed is 750 rpm. Mix for 2–3 min until uniform. Do not use a concrete mixer. |
|---|---|
| Mixing ratio | Mixing ratio: 6.5 parts Intercrete 4820 : 1 part clean water (by volume) |
| Pot life | 20 °C (68 °F) 30 min. Application of Intercrete 4820: Trowel — recommended for flat surfaces, typical thickness up to 6 mm (0.24 inch); Hand forming — recommended for small-area repairs, using a sponge or waste cloth; Float — recommended for repairing small voids and defects; a palette knife may also be used. |
| Thinner | Do not thin |
| Cleaner | Clean water |
| Interruption of work | Use immediately after mixing; discard if the pot life is exceeded. |
| 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.
Before use, refer to the Intercrete 4820 application instructions.
This product data sheet provides general methods of use for Intercrete 4820. Use on specific projects must be designed according to substrate condition, end use and environmental conditions. Consult International Protective Coatings before use to confirm the suitability of Intercrete 4820 for the project.
The project coating system provided by International Protective Coatings must always be followed.
The product is difficult to cure fully at ambient temperatures below 5 °C (41 °F). For optimum results, the curing temperature should be between 5 °C (41 °F) and 35 °C (95 °F).
For flat surfaces, before the final coat cures, trowel marks may be removed with a trowel or wet sponge to obtain a sandpaper-like surface. This step will provide a good base for application of the subsequent coat.
It is essential that the Intercrete 4820 surface be suitably protected against sunlight and drying wind. To assist curing, Intercrete 4870 curing membrane must be applied directly onto Intercrete 4820 for protection. Alternatively, polyethylene sheeting may be used.
Mechanical properties (typical values): Compressive strength (BS 4551 @ 20 °C (68 °F)): 1 day 23 MPa; 7 days 43 MPa; 28 days 55 MPa. Flexural strength (BS 4551 @ 20 °C (68 °F)): 28 days 10 MPa. Water permeability resistance: 2 mm = 1000 mm ordinary concrete. Note: VOC values are typical and for guidance only. The values may vary with factors such as colour differences and normal manufacturing tolerances.
Depending on substrate condition and the possible exposure of reinforcing steel, other surface preparation products of the Intercrete range may be required in conjunction with Intercrete 4820. For details, consult International Industrial Coatings.
