AREAS OF UTILIZATION
•Basements, foundations, and curtain walls,
•Swimming pools and water tanks,
•In wet areas such as bathrooms and WCs,
•Elevator shafts, underground garages, and warehouses,
•Tunnels and bridges,
• Used for negative and positive waterproofing of all concrete surfaces structurally in good condition, old and new.
ADVANTAGES OF THE PRODUCT
•Penetrates deeply into concrete.
•Provides water insulation by filling the capillary breaks in the concrete and
•shrinkage cracks up to 0.5 mm with the crystals it forms.
•Applicable with a brush from both positive and negative sides.
•Can be used indoors and outdoors on horizontal and vertical surfaces.
•It is suitable for use in drinking water tanks.
•Applicable to damp or not fully set concrete surfaces.
•Maintains the reinforcement of the concrete structure.
PREPARATION OF THE SURFACE
•The surface should be clean, dry, smooth, and saturated with water.
•The surface should be cleared of residues such as oil, dirt, paint that will prevent
adhesion.
•WERIMIT WETECH-REPAIR should be applied to the corners and edges.
•The application surface should be saturated with water and should be kept moist
during the application.
•Care should be taken that there is no water accumulation on the surface.
SHELF LIFE
• Shelf life is 12 months when stored in its unopened original package in a way that is not exposed to moisture, dry and direct sunlight, provided that it is placed in a maximum of 8 rows on top of each other.

APPLICATION
• 25kg WERIMIT STROMIT-CRYSTAL (Crystallized Waterproofing Mortar) should be poured slowly onto 6.5-7.5 liters of water and mixed with a low-speed mixer until a homogeneous mixture is obtained.
• Any materials not specified in the application instructions should not be added.
• The prepared mortar should be rested for 1-2 minutes to cure.
• Since it hardens in the container within 20 minutes, the material should be prepared by
paying attention to the time.
• Mix again before application.
• The prepared mortar should be applied to the surface in at least 2-3 layers with a brush
or a suitable spraying tool.
• The floors should be homogeneous and smooth, and the application should be done in
the same direction on each floor.
• After the first coat has dried, the second coat should be applied perpendicular to the
first Wait 3 hours between coats.
DRY SPREAD (Negative direction)
• When fresh concrete is poured and then it shrinks a little, or the old concrete WERIMIT STROMIT- CRYSTAL is sprinkled directly. The sprinkled concrete is thoroughly fed using a tray trowel or with a brush on the old concrete.
DRY SPREAD (Positive direction)
•WERIMIT STROMIT-CRYSTAL can be applied on concrete or old concrete just before pouring the concrete. After the application, the surface should be protected from rain and frost for 24 hours. After the coating sets, it is continued to be wetted 3 times a day for 3 days. Thus, it is ensured that the crystals fully penetrate the structure and operate.
