METHODS OF USE

IPAFLEX BITU 2K is applied in two coats, is water tight for a long period of time, without the need to introduce the fibre glass fabric (official test certificate according to DIN 18 195 standards, parts 2 and 6, chapter 4.4)

Preparation of sub-layer:
The work starts by pre-treating the sub-layer. Possible dry residues of mortar must be eliminated, as well as chips or topsoil. Possible partition joints must be sealed with a suitable product.
The sub-layer must be solid, clean, free of dust, and must not boast any traces of tar based paints or
of another type. It must be dry or slightly wet (not soaking wet).
In case of extremely porous surfaces or in the presence of gravel, the application of IPAFLEX BITU 2K
must be of "striped" type in order to avoid air infiltrations.
Similarly, in case of masonries with hollow cement blocks, which are not plastered, the open head joints
must be plastered with IPAFLEX BITU 2K.

In case of solid masonries with plastered joints, the application of plaster is not required and a stabilizer such as DURIPAL can be used as bottom coat.

Application:
The application of the bottom coat is performed with a broom or scrubbing brush. When the bottom coat is dry, apply the water tight finish. Add the powder component to the fluid component and continue to mix slowly. Continue mixing until you will obtain a homogeneous mix without clots.

The most suitable tool for mixing is an electronically adjusted drill working at slow speed, equipped with a special stirrer.
Prior to start the work, leave the mix to settle for 3-5 minutes. It cannot be worked in case of frost or
rain. Then proceed with the finish, using a trowel to smooth and apply a wet layer of 4 mm thickness.
It is suggested to protect the product against frost and rain and preserve it from the possible negative thrust of the water until it is completely dry.
It is also possible to insert the fibre glass fabric. Draining panels or insulating panels can be installed and the pit can be filled only when the layer has dried completely.

Please comply with DIN 18 195 Standards, part 10, with regards to protection layers.
