Waterproofing of water tanks and reservoirs.
Odorless waterproofing of wet areas (under-tile) in bathrooms, swimming pools, kitchens, etc.
Waterproofing surfaces in direct contact with potable (drinking) water.
Waterproofing of not well-ventilated wet rooms and areas (bathrooms, kitchens, etc.) applied.
beneath tiles, where an odorless, solvent-free coating is required

Careful surface preparation is essential for optimum finish and durability.
The surface needs to be clean and sound, free of any contamination, which may harmfully affect the adhesion of the primer.
Maximum moisture content should not exceed 5%.
Substrate compressive strength should be at least 25 MPa (N/mml), cohesive bond strength at least 1.5 MPa (N/mmll).
Old coatings, dirt, organic substances, and dust need to be removed by a grinding machine.
Oil or grease contamination must be cleaned substantially.
Possible surface irregularities need to be smoothened.
Any loose surface particles and grinding dust need to be thoroughly removed.

Stir Hard Top 2K PU Component B well before using.
Then add Hard Top 2K PU Component A at the correct mixing ratio.
Hard Top 2K PU Component A and Component B should be mixed by low-speed mechanical stirrer, for about 3-5 min. ATTENTION: The mixing of the components has to be effected very thoroughly, especially on the walls and bottom of the pail until the mixture becomes fully homogeneous.

1.5 - 2.5 kg/m² applied in two or three layers fully reinforced.
This coverage is based on practical application by roller onto a smooth surface in optimum conditions.
Factors like surface porosity, temperature, humidity, application method, and finish required can alter consumption.

Hard Top 2K PU is supplied in off-white and grey.
Due to the sensitivity of aromatic polyurethane to UV rays, the applied coating might yellow and fade on the surface.
This change in appearance does not modify its mechanical properties or leak tightness.

Hard Top 2K PU A+B is supplied in 13 kg packs.
Pails should be stored in dry and cool rooms for up to 12 months.
Protect the material against moisture and direct sunlight.
Storage temperature: 5°C - 30°C.
Products should remain in their original, unopened containers, bearing the manufacturer's name, product description, batch number, and application precaution labels.
