Application Procedure:
Surface Preparation:
Application surfaces should be dry and clean. Concrete and plaster residues should be
mechanically; Oil, grease, fuel and paraffin wastes should be cleaned using chemical
solvents. Damages and cracks must be repaired with products that are available. Ambrosi
PU 157 should be applied priming with a suitable primer based on epoxy or polyurethane
after depending on the surface condition.

Application:
Ambrosi PU 157 is applied with a sausage gun.
• The applied material should be protected against water and rain, external factors and
mechanical stresses until it cures.
• By using backing rod, the consumption of Ambrosi PU 157 is prevented from
sticking to the joints. The size of the backing rod must be greater than 20% to 25% of
the joint diameter.
• Joint width and depth should not be less than 5mm.
For hand applications; place the sealant Ambrosi PU 157 into the gun and inject the sealant
into the joint without causing any air bubble
Chemical resistance:
It is resistant to water, sea water, dilute alkalis, cement slurry and water dispersing
detergents.

Warnings:
• It should not be applied in closed areas due to long-term solvent odor or the
environment should be well ventilated.
• Surface temperature must be +5ºC. The mixture of the material should be made with
a special mixing device and tip that does not exceed 300 - 400 D/D and should not
be mixed with a high speed drill.
• In cold weather, packaging must be kept at least 24 hours +15ºC before application.
• There should be no water vapor pressure on the surfaces to be applied on. In such a
case, special insulation should be applied before the application.
• After application, the surface should be protected from water, rain, raw, snow, hail
and so on until it is fully dry.
• Total mechanical and chemical resistance is achieved in 7 days.
Cleaning Tools:
Cleaning of tools can be cleaned with ethyl acetate or other suitable solvents, before curing
Ambrosi PU 157. Dried materials can only be cleaned with mechanical applications.
Storage:
• It has a shelf life of 12 months in unopened and undamaged packages protected
from moisture, water and sunlight.
