YuGuard^™ Sil-Mastic

Sil-Mastic Silicone Roof Sealant

The YuGuard Sil-Mastic is a specialized, high-performance sealant designed as a critical preparatory component of the YuGuard Silicone Roofing System. Formulated to work seamlessly alongside the YuGuard Sil-HS 100% premium silicone coating, this mastic provides targeted defense for the most critical and easily compromised parts of your roof prior to the final coating application.

Core Advantages

Targeted Repair

Specifically engineered to address and reinforce vulnerable areas across the roofing substrate.
Precision Sealing

Effectively seals cracks and gaps to prevent moisture intrusion and ensure a perfectly watertight foundation.
Enhanced Joint Protection

Provides an extra, durable layer of protection on critical joints and seams where structural movement and leaks are most likely to occur.

Applicable Acenarios

For Asphalt/Bitumen Roofs

After preparing the surface with YuGuard Cleaner and applying YuGuard BBL (to eliminate the possibility of asphalt bleeding), apply Sil-Mastic to seal any cracks, gaps, and joints. Once these vulnerable areas are addressed, the roof is ready for the final Sil-HS coating.
For Aged TPO Roofs

After deep cleaning the roof with YuGuard Cleaner and applying YuGuard TPO Primer for optimal adhesion, use Sil-Mastic to treat all vulnerable areas, cracks, and joints before finishing the system with the seamless Sil-HS shield.
