What do we need?

In cases where there are no inclinations  formed on the concrete slab, we have the phenomenon of standing waters, whenever there is rainfall. We should protect the surface terrace from moisture to avoid further problems either at the surface of the concrete slab (terrace) or on the ceiling of the house (from the bottom of the roof) .

How do we do it?

To protect the surface from the standing water, we should apply the hybrid waterproofing membrane FLX 388 PU, which offers high protection from moisture and is highly resistant to UV rays and mechanical stress.

Step by step

Remove any loose from the concrete slab.

Wash with plenty of water so as not to leave any residues (dust, oil, grease) and any molds and algae that have been developed to the plate surface. Standing waters should be removed.

Prime all surfaces with high penetration  acrylic primer GLX 292 FLEX PRIM. Large cracks (> 5 mm) and gaps close with fiber reinforced repairing mortar WRM 525.

At the corners of the barriers to the plate, creating with WRM 518 an appropriate curve so as not to let water stand at this point.

When the surfaces dry thoroughly,  apply two layers crosswise with a roller the acrylic waterproofing emulsion FLX 388 PU.

The first coat is applied diluted with 5% water.

When the substrate is cracked strongly recommended that the THRAKON FABRIC with at least three layers of material, between the two coats of FLX 388 PU.

If loads of moisture are expected to be larger, then a third coat is applied. Each hand is applied when the previous has dried.

The application of the material should be avoided when there is forecast for rain on the day of application.

The surfaces on which the sealing emulsion FLX 388 PU has been applied, should have slight patency.

The properties of FLX 388 PU are visible 7 days after its application.
