BYTUM SLATE 3500
BYTUM SLATE 3500 is the reinforced bituminous membrane that ensures effective waterproofing of timber structures and, thanks to its slated surface, it ensures permanent stability to UV rays.
It consists of distilled bitumen with elastoplastic polymers and a slate coating, and is designed for application on the external side of the roof.
Description
BYTUM SLATE 3500, EFFECTIVE WATERPROOFING AND PERMANENT UV STABILITY
BYTUM SLATE 3500 can be used for flat roofs as the final visible layer in combination with the self-adhesive and self-sealing sheath, BYTUM BASE 2500, for optimal waterproofing.
Can be used as an underlay also for low-pitched roofs. Guaranteed flexibility and workability even at low temperatures ensure easy installation.

Description
The application surface must be dry, free of dust and grease, and not be anti-adhesive. Surface elements must be removed so that the membrane is not damaged during application.
Guaranteed flexibility and workability even at low temperatures ensure easy installation.
The exposed slated top layer provides long-lasting weather resistance by protecting the bitumen waterproof layer.
Recommended use: The membrane is designed for applications on the exterior side of the roof.
Used on slopes from 5° as an underlay, this adhesive bituminous membrane guarantees excellent water tightness.
Installation:
Unroll the membrane over the surface, progressively remove the release film from the adhesive, and press the membrane firmly to ensure proper adhesion.
Once membrane installation is complete, a pressure roller must be used to ensure perfect adhesion.
In cold climates, the adhesive side of the membrane can be preheated using a hot air gun, such as HOT GUN, to achieve optimal bonding
