ADVANTAGES

-High flexibility. -Resistant to U.V. radiation. -Obtained from recycling processes -Good water vapour permeability -Suitable for contact with drinking water -Complete waterproofing cycle within one day -Suitable for contact with purifier water and domestic wastewater -Reduced  environmental impact thanks to the use of raw materials with low carbon footprint and -Reduced volatile organic compound (VOC) emissions -The product helps earning points for LEED certification -Adheres to different types of surfaces (concrete, brickwork, brick, gypsum board, plastic, metal, ceramic, polystyrene, wood, other) -Protects concrete surfaces from CO₂ (Carbonation) -Excellent workability and quick application.

FINISHING

The product can be finished with CRYSTAL POOL (see related technical data sheet) or ceramics, depending on the intended use. Ceramics must be laid with a large grout gap and C2-type adhesive (preferably with an S1 and S2 deformation class). Line grouting works must be carried out with CG2 class cement-based grouting mortars. When applied indoors, it is recommended to coat the walls with the macroporous CALIBRO as an anti- condensation layer. It is also possible to complete the finish with X-LIME

PRODUCT APPLICATION

Positive and negative hydrostatic pressure waterproofing of structures made of concrete, cement blocks or mixed masonry, previously levelled with suitable VOLTECO mortars, affected by moderate settlements and/or movements.

Particularly suitable for:

-Walls and foundations slabs and reinforced cement floors in garages, cellars, underground structures in general -Slabs and structures exposed to contact with water -Substrates in general, also lightened with expanded clay -Tanks, channels and structures also intended to contain drinking water, reinforced concrete foundation walls, pools, etc.

FLEXONET OR XNET REINFORCEMENT MESH

To improve elastic performance, in case of application in positive pressure (ex. crazing with dynamic behaviour, in roof top pools and structures that are potentially subject to cracking), it is advisable to place the FLEXONET or XNET mesh “fresh on fresh” on the 1st coat, pressing it down with a metal spatula until it is completely embedded. The edges of adjacent sheets must overlap by 10 cm. Where the horizontal and vertical surfaces join, make sure the BI FLEX mesh adheres to the horizontal edge of the previously laid joint cover. Never fold the mesh vertically, always join it to the BI FLEX system. At expansion joints treated with the BI FLEX System, the mesh must be interrupted.

PREPARATION AND APPLICATION PREPARING THE SURFACES

Verify the structure suitability for the hydrostatic loads; if intended to contain water, perform a preload test. Remove any dirt, oil, paint and any material or deposit that could compromise adhesion of PLASTIVO by pressure blasting, sandblasting or bush-hammering lightly. The surface that is to be treated must be solid and perfectly clean from cement laitance. Repair the surface with suitable VOLTECO mortar if the surfaces are very uneven, have gravel nests or in the case of mixed masonry. If the surfaces are old and/or dusty or partially soaked with water, apply PROFIX 30 or PROFIX 60 primer (see the related technical data sheets) with a roller, a brush or by spray, ensuring it does not bleed on the surface.

PREPARATION OF ELEMENTS OF DISCONTINUITY ON THE SURFACES (POSITIVE HYDROSTATIC PRESSURE)

-Construction Joints Connect the construction joints between the bed and the vertical wall by forming a 3x3 cm fillet with SPIDY 15 rapid-setting mortar -SPACERS Remove the spacers on both sides of the wall and plaster with SPIDY 15 rapid-setting mortar -PASSING BODIES Seal all the passing bodies, including spacers and pipes, with AKTI-VO 201 mastic (see related technical data sheet) -JOINTS and CRACKS Connect all marked joints and cracks with the BI FLEX System.

APPLICATION

If PROFIX primer has not been applied, wet the surfaces making sure no surface water is formed. PLASTIVO 250 must be applied in two layers with a VOLTECO ROLLER, brush, squeegee or spatula. Apply the first layer of PLASTIVO 250 on the surface, approximately 1 mm thick (average consumption: 1.8÷2 kg/m²), making sure the product penetrates well into the substrate, in order to obtain uniform coverage.

WARNINGS - IMPORTANT NOTES

The product is not a vapour barrier. The product must be used within 20 minutes after mixing. Do not apply PLASTIVO 250 on water-soaked surfaces; first seal with TAP 3/I-PLUG hydraulic mortar. Do not add water to the mixture or alter the mixing ratio. Do not apply the product if the temperature is higher than +30°C or lower than +5°C or if it is expected to drop below this temperature within 24 hours. If more than 28 days have passed since the second coating, an additional layer must be applied to ensure the subsequent coating adheres well.

Do not use PLASTIVO 250 for layers thicker than 1.5 mm. Protect wet product from rain. Finishing with solvent-based paints may degrade PLASTIVO 250, check its compatibility via preliminary tests. The preparation and installation data refer to normal environmental conditions (temperature +20°C; relative humidity 60%).
