Coating Comparison
Silicone vs. Acrylic Roof Coating
Both can be useful roof-restoration materials. Their strengths, limitations, and ideal applications are different.
| Category | Silicone | Acrylic |
|---|---|---|
| Water resistance | Often selected where stronger resistance to persistent water exposure is needed | Works well in suitable drainage conditions; persistent ponding may be restricted by some products |
| UV exposure | Excellent resistance to UV degradation | Good to excellent reflectivity and UV performance |
| Dirt pickup | Can attract and hold dirt more readily | May maintain a cleaner appearance in some environments |
| Application | Moisture-cured; environmental and recoat requirements matter | Water-based; temperature, humidity, and rain windows are important |
| Traffic resistance | Can be slippery and may need walk pads | Varies; traffic areas still require system-specific treatment |
| Typical reason to choose | Water resistance and long-term weathering | Reflectivity and economical restoration in good drainage conditions |
The correct choice is product- and roof-specific. Manufacturer instructions, adhesion testing, drainage, climate, and warranty requirements must be considered.
Why RAM Focuses on Silicone
A Strong Match for Many Southwest Flat Roofs.
Silicone’s UV resistance, reflective white finish, and water resistance can make it a strong restoration option for eligible flat and low-slope roofs exposed to intense sun and seasonal storms.
