About the product

Bitüra Slate has natural slate granules pressed into the top face of a polyester-reinforced modified-bitumen sheet. The granules protect the membrane from UV, lower surface temperature and give a walkable texture.

It is always the top layer of two-layer systems. A granule-free selvedge gives clean, watertight laps. Available in grey, green and tile red.

Areas of use

Exposed terraces and flat roofs
Industrial roof refurbishment
Eaves, valleys and parapet upstands

Application steps

Sweep the deck, remove loose material and sharp edges; screed moisture must be below 4%.
Apply Astarix bitumen primer at about 0.3 kg/m² and let it dry completely.
Form fillets at upstands; pre-treat drains and penetrations with reinforcement pieces.
Torch-apply the rolls with 10 cm side laps and 15 cm end laps.
Check a 5–10 mm bitumen bleed at laps; lay the second layer offset by half a roll.
Turn the membrane at least 20 cm up the parapet and fix it with a termination bar and sealant.
