General Information
WEBAC Surface Sealants
Special reactive bitumen-acrylate sealants are
used for sealing surfaces in undergrade or freely accessible buildings and structures. These
systems also withstand high water loads and are
especially suited for use in the protection of historic monuments. In addition, plastic modified
high-build bituminous coatings (KMB) according to DIN 18195 are used as (classic) surface
sealants in buildings and structures. Reinforcement fabric is used as reinforcing material in
the area of joints and for bridging cracks.
Mixing
• The containers are provided according
to the required mixing ratio
2 min
• Use the material immediately after mixing
Please observe the mixing instructions
for the respective material.
2 min
Application
Bitumen-Acrylate Dispersion
Preparatory work
It is recommended to apply a thin coat of primer
(WEBAC 5611 without cement) before the application of WEBAC 5611. Apply the bitumen-acrylate dispersion by roller or wide brush. Reinforcing
fabric can be used to reinforce cor ners and to
bridge expansion joints.
®
Structural analysis before the application:
• Nature of the substrate
• Structural conditions (temperature and air
humidity)
®
• Water load classes
Undercoat
• Existing surface interruptions due to fitted
components (e.g. pipe ducts)
Substrates must be primed with an undercoat of
WEBAC 5620 before applying WEBAC high-build
bituminous coatings.

Polymer modified high-build
bituminous coating
• Selection of the suitable product
• Pretreatment of the substrate
Substrates must be free of loose and separative
substances. Slightly absorptive substrates should
be roughened using a suitable method. Open
joints, concave moldings and rounded edges in
corners must be closed with mortar or floated to
obtain a closed, smooth surface. Old, firmly adhering bituminous sealants can be reworked after
cleaning. An installation finish must be applied on
concrete substrates before applying the high-build
bituminous coating; the coating material itself can
be used as installation finish.
Apply the polymer modified high-build bituminous coating at the respectively required layer
thickness by smoothing trowel or trowel in at
least two operations. Air humidity and sunlight
influence the curing speed. Only use pure WEBAC
surface sealants without any residues from
cleaning agents or other impurity.
For further information on the use of high-build
bituminous coatings, please see current norm.
Cleaning
• Clean the equipment thoroughly with water
any time work is interrupted for a longer period
of time and after use
• Remove cured residues of WEBAC 5620
with white spirit
