Coverage
Coverage
Approx. 2.6 kg/m² corresponding to 1.3 kg/m² per mm coat + approx. 3.5 kg sand.
Packaging
10 kg units containing matching volumes of each component, A and B.
Sand is available in 25 kg bags.
Features
Generel
Expected Result
Application
For interior and exterior under-tile water proofing in e.g. dairies, milking rooms, slaughterhouses, in- and outdoor swimming baths, and purification plants. Upon curing the membrane is water and liquid proof and resistant to a number of chemical and mechanical stresses.

Finishing
Sealings
For sealing of junctions between wall and floor, movement joints, internal corners, and around sanitary installations, prepare adapted pieces of Alfix Sealing strip to be subsequently bedded in a coat of Alfix Epoxy Primer.
Pipe penetrations and drains should be incorporating flanges ready to receive sealing strip and drain mats.

How to use
Surfaces
Concrete in situ and concrete slabs, older than 3 months.
Cohesive strength should be min. 1.5 N/mm²
Surface preparation
The surface should be pretreated with Alfix Epoxy Primer scattered with quartz sand. Drying time for primer is approx. 16 hours. The surface should be completely saturated with sand.
Remove any excess sand by sweeping or vacuuming when cured.
How to use
Add full content of component B into component A and mix the two components using slowly rotating paddle attached to electric drill. Mix thoroughly for approx. 3 minutes.
Working time is approx. 45 minutes at +20°C.
Apply membrane as 2 coatings in order to obtain even, fully covering layers of each 1 mm. Embed Sealing strip and drain mat into the first layer.
Apply by short pile paint roller or by 4 x 4 mm notched trowel. Allow first layer to dry before applying the second. Curing time is approx. 16 hours at +20°C
NB!
First layer must not exceed the age of 48 hours before second layer is to bed applied.
Scatter with dry quartz sand, type 2, over the still wet coating of Alfix Epoxy membrane until the surface is completely saturated and will provide a sandpaper-like finish. If possible, use sand blasting gun.
According to Danish legislation, working with epoxide products requires special training.
To improve slip resistance on walls, add 2 – 3% thixotropic admix. For further details, contact our Service Technical Dept.
Cleaning
Residues from Alfix Epoxy Membrane on tools should be removed immediately upon use with ethanol.
Once cured, membrane can only be removed mechanically.
