Instant Roof Waterproofing I Winkler 2000 Fast System
In this residential roofing project in Milazzo, the contractor needed a system capable of waterproofing and protecting the roof immediately after membrane installation – avoiding the traditional waiting time required for new bituminous membranes to oxidize.
By combining Coverextra with the WINKLER 2000 Fast System, the team eliminated oxidation delays entirely. The protective coating was applied right after installation, ensuring instant durability, reliable waterproofing, and a clean, long-lasting aesthetic finish from day one.
Project Goals and Challenges
The contractor needed to:
- Waterproof the roof surface
- Apply a protective coating immediately
- Ensure long-term durability and an attractive finish
- Avoid construction delays and additional costs
Under normal conditions, newly installed bituminous membranes require a waiting period of around six months before applying a protective coating. This oxidation phase prevents issues such as:
Detachment of the coating
Yellowing or discoloration
Poor adhesion
Oil migration
Such delays are incompatible with the fast-paced timelines of modern construction projects.
Perché attendere l’ossidazione della membrana è un problema
Le membrane bituminose di nuova produzione rilasciano sulla superficie degli oli di affioramento. Se un protettivo viene applicato troppo presto, questi oli compromettono l’adesione del rivestimento, causando:
- Distacchi localizzati o diffusi della vernice.
- Ingiallimenti antiestetici del colore scelto.
- Migrazione degli oli che sporcano la finitura.
Senza una tecnologia specifica, il cantiere sarebbe rimasto bloccato per un intero semestre, esponendo la membrana nuda agli agenti atmosferici senza la protezione definitiva dei raggi UV.
Winkler Technical Solution
Winkler provided the ideal answer with the 2000 Fast System, specifically engineered to allow protective coatings to be applied right after membrane installation – without waiting for natural oxidation.
The system includes:
- An oil-blocking primer to prevent migration
- A coloured or reflective elastomeric protective coating
- Water-based, solvent-free technology
- The result is a roof that is stable, waterproof, and protected from day one.

FAQ – FREQUENTLY ASKED QUESTIONS
- Why is waiting normally required before protecting a bituminous membrane?
Because membranes need time to oxidize, reducing oil migration that can cause coating detachment or yellowing.
- Is it really possible to apply the protective coating immediately with the 2000 Fast System?
Yes. The primer blocks surface oils, enabling immediate coating application.
- Is the system suitable for roofs exposed to water ponding?
Yes. The elastomeric coating is designed to resist water ponding and full weather exposure.
- Are the products safe for operators and the environments?
Absolutely. They are water-based, solvent-free, and low-emission – ideal for modern construction sites.
- Can roof reflectance be improved?
Yes. The Reflex versions increase solar reflectance and can reduce surface temperatures by up to 50%.
