Product data

A ready to use one-part water based elastic bitumen seal. OMEGA PoBit is particularly suitable for seamless sealing work at critical spots in the window and door areas, as second water-bearing level below window sills, at penetration points and as sealant for bases outdoors. OMEGA PoBit can also be used in the waterproofing of buildings in the relevant areas stated in ÖNORM B 3691 and ÖNORM B 3692. OMEGA PoBit Sealing Compound bonds on many substrates, such as wood, concrete, aerated concrete, metal, plaster, polyester, gypsum materials, pre-treated bitumen sheets and rigid foam sheets (EPX, XPS, PUR).

Processing guideline

Preparation of substrate:

The substrate must be dry, frost-free, absolutely clean and free from dust, oil, grease, peeling surfaces or areas with poor adhesion, remains of lime, plaster or colour. Check suitability of any slope and residual moisture of substrate.
Preparation of substrate:

Sealing with OMEGA PoBit Sealing Compound:

OMEGA PoBit Sealing Compound is applied using a hand scraper, paintbrush or roller to apply an approx. 1 mm thick layer and pressing this on firmly in order to obtain the best possible adhesion to the substrate.
The reinforcement tape is applied to the first layer while it is still moist. Tape overlaps must be 10 cm. The second coat can be made fresh on fresh if the first layer is reinforced, otherwise on the next day.
The minimum thickness of the layers required by ÖNORM, depending on the area of application, must be observed. When sealing in the base area of a building according to ÖNORM B 3662 OMEGA PoBit Reinforcement Tape should be used with a minimum layer thickness of 2 mm.
Sealing with OMEGA PoBit Sealing Compound:


Vertical wall connections and component joints must always be reinforced. OMEGA PoBit joint tape should also be used for areas larger than 10 m² or for loaded substrates.
When applying with a trowel, an even result is achieved using a notched trowel with 4-6 mm tooth spacing. Draw the smooth side across the surface to obtain a uniform thickness of about 2 mm.


The ideal processing temperature is +5 °C to +35 °C. At temperatures below +10 °C the OMEGA PoBit Hardening Accelerator should be used to shorten the drying time. The OMEGA PoBit Hardening Accelerator is ready dosed and is mixed into the 10 kg bucket. Careful and thorough mixing is necessary.


OMEGA PoBit Primer is to be used on crumbling concrete, plaster and masonry substrates. The OMEGA PoBit Primer also firms up old plaster and increases its compaction. The surfaces to be treated must be clean, dry and free from loose material. The minimum processing temperature of OMEGA PoBit Primer is +5 °C.

Coated bitumen membranes (PE-coating, sanding, talc coating) must be pre-treated (e.g. flame treatment) in order to achieve a direct bonding layer with the bitumen.
