15 years warranty.

Double Guard System is designed to provide maximum outdoor resistance to degrading agents such as sunlight, rain, humidity and smog.

Hail resistance*.

Hybrid Pro wood stains of Renner Itala represent the synthesis of water and solvent technologies. Choosing Hybrid Pro also means choosing wood stains with improved hail resistance. Hybrid Pro drastically reduces the risk of peeling near hail cracks. This is a result of the super adhesion of these wood stains. Using Hybrid Pro wood stains does not mean zero damage. However, it does reduce the potential for coating peeling near the crack. Hybrid Pro wood stains make any restoration job easy.

Easier application.

All products of Double Guard System are extremely fast drying. Hybrid Pro wood stain is synonymous with strong adhesion even in extremely humid conditions, does not fear wood instability, prevents fibre lifting and prepares the substrate for the application of isocyanate-free topcoats.

Attending the training of diisocyanates worker? Not necessary.

Niso Exterior 2K System is the coating programme that does not require a training of diisocyanates workers. Choosing Niso Exterior 2K System topcoats and hardeners means complying with regulations and making life easier. And, of course, access to the highest standards of durability and aesthetics by Renner Italia.

More safety, less restrictions.

Niso Exterior 2K System products have less occupational health and safety restrictions: they don’t contain flammable, corrosive and toxic components. That’s why they have labels with reduced warnings.

*Renner Italia warranty programme does not cover damages as a result of hail events.
