Biała silikonowa hydroizolacja DoPox® SiRC
DoPox® SiRC 100% silicone white roof coating is a single-component waterproofing solution, ready to use and easy to apply. It can be used as a maintenance system for sealing and repairing existing low-slope roofs. It forms a seamless, flexible, and UV-resistant membrane that helps protect the roof, reduce building heat gain, and extend the service life of the roofing system.
- SRI = 109 - Thanks to its high Solar Reflectance Index (SRI), it helps reduce roof surface heat buildup and supports the building’s energy efficiency.
DoPox® SiRC white silicone waterproofing is solvent-free and also stands out for its high flexibility, vapor permeability, and very good resistance to water and weather conditions. The product can be applied by spray, roller, or brush, and the coating dries within 1 to 4 hours, depending on temperature and humidity.
Product available to order - lead time: 4 weeks.

Why choose roof refurbishment with the DoPox® SiRC system?
Among the many advantages of using the 100% silicone roof coating DoPox® SiRC is its high reflectivity, which supports the building’s energy efficiency. It creates a seamless seal and provides protection against leaks, long-term standing water, and the harmful impact of harsh weather conditions on roofs.
DoPox® SiRC retains its properties over time — it remains stable and flexible, instead of becoming brittle and hardening, which could lead to damage to the roofing system.
Seamless waterproofing and resistance to long-term standing water
One of the key advantages of the DoPox® SiRC system is that it creates a uniform, seamless waterproofing barrier, which reduces the risk of leaks forming at joints.
Unlike many acrylic and asphalt coatings, the silicone coating offers high resistance to the destructive effects of long-term standing water, ensuring effective and durable roof protection.
Supports energy efficiency
Roofs are surfaces particularly exposed to intense heat buildup due to solar radiation.
The white DoPox® SiRC coating is characterized by a high ability to reflect solar radiation, which means it absorbs significantly less thermal energy than traditional roofing materials.
As a result, it helps reduce the temperature inside the building, contributing to lower energy consumption and air conditioning costs.
High durability and UV resistance
The DoPox® SiRC system has been designed to perform under intense weather exposure and UV radiation.
The coating remains stable under ultraviolet radiation and does not become excessively hardened or brittle during service.
As a result, it reduces the risk of damage, which is often one of the main causes of failure in traditional roofing systems.
SRI value for DoPox® SiRC
- SRI = 109
The term “Solar Reflectance Index” (SRI) refers to the interaction of a surface with solar energy:
-
SRI - Solar Reflectance Index
- SRI is a more comprehensive measure that takes into account not only reflectance, but also the emissivity of the material. Emissivity is the ability of a material to release absorbed heat.
- SRI is calculated based on solar reflectance and thermal emissivity values to determine how hot a surface will become under sunlight compared with standard black (with reflectance 0 and emissivity 0.90) and standard white (with reflectance 1 and emissivity 0.90) under the same conditions.
- SRI values typically range from 0 to 100, with higher values indicating materials that stay cooler in the sun by reflecting solar radiation and efficiently emitting thermal radiation.
SRI provides a holistic view of how a surface will behave in terms of heat gain from solar exposure by combining reflectance and emissivity into a single index.

Systems:
The table below shows which system should be used depending on the substrate.
| Substrate | System type | System | Cost |
|---|---|---|---|
| Bituminous roofs** | Thermal protection | 0.30 kg/m2 Elastodeck + 0.25 kg/m2 DoPox® SiRC |
from PLN 29.00 net per m2 |
| Sealing + thermal protection | from 1.5 kg/m2 Elastodeck* + 0.25 kg/m2 DoPox® SiRC |
from PLN 81.00 net per m2 | |
| Steel roofs | Thermal protection | 0.25 kg/m2 Elastometal + 0.25 kg/m2 DoPox® SiRC |
from PLN 29.00 net per m2 |
| Anti-corrosion + thermal protection | 0.6 kg/m2 Elastometal + 0.25 kg/m2 DoPox® SiRC |
from PLN 47.00 net per m2 | |
| Anti-corrosion + sealing + thermal protection | from 1.3 kg/m2 Elastometal + 0.25 kg/m2 DoPox® SiRC |
from PLN 83.50 net per m2 | |
| EPDM | Thermal protection | 0.3 kg/m2 Elastodeck diluted with 5% water + 0.3 kg/m2 DoPox® SiRC |
from PLN 31.50 net per m2 |
| Painted, non-chalking walls | Thermal protection | 1-2 x 0.3 kg/m2 DoPox® SiRC | from PLN 19.00 net per m2 |
* To calculate the system cost, we use:
1.25 kg of Elastodeck in RAL 7008
+ 0.30 kg of white Elastodeck
+ 0.25 kg of DoPox® SiRC
** Bituminous substrates must be weathered for a minimum of 1 year before system application. For additional sealing and/or improved adhesion to roofing felt, a priming layer of Elastodeck is recommended. For small projects (up to 100 m2), DoPox® SiRC can be applied directly to roofing felt; however, the durability of the system with Elastodeck is superior. Application on roofs with a 3% slope is recommended to reduce water ponding.

Important: Roof safety and anti-slip properties
Due to the properties of 100% silicone, a roof surface coated with DoPox® SiRC becomes very slippery when in contact with water.
- Risk zones:
In areas where people are present (especially within zones 3-4 meters from the roof edge and along walkways), the use of an anti-slip additive is absolutely essential. - Recommended application method:
To achieve optimal slip resistance on a wet coating, we do not recommend mixing aggregate into the liquid in the bucket. The most effective solution is to broadcast the aggregate directly onto the wet, freshly applied coating.
For slip protection, the following are recommended for broadcasting:
