About this item
- DEFEATS PONDING WATER: Unlike standard coatings that fail under standing water, our 100% Silicone formula remains stable and leak-proof even on sunken or uneven flat roofs.
- PERMANENT UV SHIELD: Engineered to withstand the harshest solar exposure without becoming brittle, cracking, or peeling; ensures your roof stays protected for decades.
- LIFETIME ROOF RENOVATION: One thick application provides a professional-grade seal, significantly extending the life of old bitumen, GRP, or metal roofs with zero maintenance.
- RAIN-SAFE IN 1 HOUR: Fast-curing technology provides immediate protection against unpredictable weather, becoming rain-resistant shortly after application.
- SEAMLESS BREATHABLE BARRIER: Forms a monolithic membrane that keeps external water out while allowing trapped moisture to escape from the building structure.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
