Waterproofing and Concrete Protection Mortar

Product Definition
Rapid curing, highly fl exible and durable waterproofi ng and concrete protection mortar for interior and exterior applications, composed of emulsion polymer based liquid and waterproofi ng,
workability improving mineral additives and special elements containing powder components.

Application Areas
> Waterproofing of sub-basements.
> Waterproofing of underground concrete elements like foundations, retaining walls, basement walls.
> Waterproofing of the soil contacting areas of concrete elements.
> Waterproofing of places subject to deformation, pedesterian and load traffi c.
> Waterproofing of old bitumenous surfaces.
> Waterproofing over old tilings.
> Waterproofing of wall interfaces.
> Waterproofing of balconies and terraces.
> Waterproofing of the areas subject to saline water.
> Waterproofing of concrete basins subject to sea water and de-icing salts.
> Waterproofing of permanently wet areas like swimming pools and water basins.
> Waterproofing of wet areas bathrooms, showers.
> Waterproofing under ceramic tiling.
> Waterproofing of concrete, plaster and screeds.

> Resistant to ageing and UV light.
> Excellent bonding on all concrete and masonry, highly fl exible.
> Non-corrosive for steel and construction elements.
> Resistant to rain within 2 hours, to pressurized water within 16 hpurs after application.
> Allows further application over the surface rapidly, paintable.
> Applicable both on horizontal and vertical surfaces.
> Prevents carbonation in concrete.
> Resistant to freeze-thaw.
> Highly resistant against chloride ions.
> Prevents concrete against de-icing salts like calcium and sodium chloride, seawater and carbondioxide gas.
> Easy to apply either by brush, roller or trowel.

Application Instructions
> The substrate must be solid, dry, free of dust, loose parts, paint, wax, oils, rust and traces of gypsum.
> Cementitious substrates must be cured.
> Use TamirArt in case of any loose and uneven substrates to get a sound and fl at surface.
> The substrate should be protected from sunlight, precipitation and dust for 1 day and application should not be under direct sunlight. Dampen absorbent surfaces to be treated beforehand with water or better apply Kalekim Astar.
> Pour 10 litres liquid component into a suitable clean container.
> Then slowly add 15 kg. powder component and mix with a low speed of 400-600 rpm mixer to obtain a homogenous lump free mix for minimum 2 minutes.
> If the substrate is porous, Ultralastic should be penetrated into the pores by trowelling.
> Application should be done in one or two layers depending on the situation of the area to be waterproofed. Max. 8 mm thickness is allowed at once. Second layer should be applied after 2 hours
and in the perpendicular direction to the fi rst one. Please refer to the consumption amounts indicated in the technical properties section.
> Use Ultralastic within 45 minutes of preparation. Unfavourable climatic conditions (high temperature, low humidity,
wind etc) can reduce this time to just a few minutes. Dispose mortars of which pot life is expired. Clean tools and hands with water, surfaces with a damp cloth.
> When Ultralastic is used waterproofi ng drinking water tanks, do not fi ll the tank before waiting 28 days for curing
and following washing down with hot water several times.
> Coating whould not be taken into service until hardening of the surface is enough (about 16 hours).
