  • Thanks to its excellent adhesion to various surfaces and its superior elasticity, the product is used as a primer and bonding cement system to other systems.

Technical specifications

Cracks bridging capacity – 2.27 mm.

Adhesion strength to concrete – 1.18 Mpa.

Water vapors passage – 1.86 meter = SP.

Elongation in maximum load – 51%

Resistance to water pressure (7 Atm) – o.k.

Resistance to negative water pressure (1.5 Atm) – o.k.

Water permeability

According to tests conducted by the standards institute: No water penetration at 1, 3, and 7 atmospheres.

Substrate

Concrete, concrete and Ytong blocks, silicate, plaster, etc.

                                                                 

Method of application

  • Remove dust, dirt, grease, and loose parts off the surface.
  • Rinse the surface to saturation and remove water surplus.
  • Chisel out and around external defects, embedded gravel, wires, and exposed reinforcing steel and repair prior to applying the sealer.
  • Fill and smooth wall-floor corners, using the appropriate materials 48 hours before applying BITUMSEAL FLEX.
  • Pour the contents of one bucket (10 kg) BITUMSEAL FLEX part B into a container of a mechanical mixer. Start mixing and add slowly, while mixing, the contents of part A bag. Mix thoroughly until a homogenous, easy to apply mixture is obtained. Rinse the adhesive residue in the bucket with about 1 liter of water and add to the mixture.
  • Apply the prepared mixture on the side of the wall that faces the water (positive and negative sealing), using a brush or a trowel. In the event of repaired spots, apply the mixture over the repair after it dries.
  • It is recommended to use BITUMSEAL FLEX in two colors, to ascertain full coverage of the surface by the sealer.
  • Apply 2-3 coats according to the expected moisture. Apply the coats at 12-24 hours intervals, in crisscross direction, using different colors. In water tanks apply 3 layers, 1.25 kg/m² each.
  • After finishing the last layer of BITUMSEAL FLEX, wait 6-10 hours for initial drying and then start to wet the surface with clean water, 2-3 times a day, for 2-3 days, in order to achieve good properties of the products.

Consumption

About 1.25 kg/m² in one coat (1 mm dry thickness). For sealing against water pressure over 3 meters high, apply 3 coats.

Workability

About 90 minutes. It is recommended to stir every 15 minutes, to prevent crusting

Packaging

Part A, powder: 25 kg paper bags

Part B, liquid: 10 kg plastic bucket

Cleaning

Clean with water, while the mixture is still wet. Clean dry mixture with acetone.
