• Cover the fabric with the waterproofing product and blend it in with
the previous layer (Fig. 5.9).
Waterproofing in correspondence with drains in parapets must
be carried out using DRAIN FRONT, TPE angular pipe unions for
balconies, applied as follows:
• Make a hole in the parapet and floor large enough to insert the
DRAIN FRONT.
• Spread on an even layer of ADESILEx PG4 two-component,
thixotropic epoxy adhesive with a smooth trowel on the clean, dry
substrate.
• Place the DRAIN FRONT in position and press down lightly so that it
is embedded in the ADESILEx PG4 (Fig. 5.10).
• Spread on a second coat of ADESILEx PG4 fresh on fresh to
completely cover the DRAIN FRONT (Fig. 5.11).
• Smooth over the surface with a flat trowel and, while the product
is still fresh, sprinkle on a layer of 0.5 spheroid quartz (Fig. 5.12) to
create a substrate which is rough enough to form a good bond with the
waterproofing product.
• Once the curing process of the ADESILEx PG4 has been
completed, remove any loose quartz.
Flexible waterproofing of the fillets between horizontal and vertical
surfaces must be carried out using MAPEBAND, alkali-resistant
rubber tape with felt. Firstly, even out the masonry where the render has
been removed using NIVOPLAN, levelling mortar with added synthetic
rubber latex, such as PLANICRETE at a rate of 2 litres per bag of
