AQUAFIN®-1K

One component mineral-based waterproof slurry

Properties:

  • Rigid waterproof slurry
  • Sulphate resistant
  • For interior and exterior use
  • For wall and floor
  • Water impermeable
  • Suitable for all load-bearing conventional building substrates
  • Hydraulic cure
  • Easy efficient application
  • Can be brushed, trowelled or sprayed with suitable equipment
  • Bonds to matt damp substrates without priming
  • Vapour permeable, resistant to frost and ageing
  • Application schedule against negative hydrostatic pressure
  • Application schedule against aqueous solutions aggressive to concrete in accordance with DIN 4030

Areas Of Application:

Waterproofing of new and existing buildings in ground covered areas against ground moisture, seepage water and water under pressure, water pressure from the inside, retrospective internal waterproofing against damp penetrating from the exterior as well as a horizontal membrane within and beneath walls and in building plinth areas. Weathered or greenery covered, concrete cold roofs above underground garages, prefabricated garages, service water containers, waste water containers and pipes, retaining walls and sluices. For use on wall or floor surfaces and for retrospective treatment of substrates not at risk of cracking. When using in containers or where there is exposure to soft water with a hardness < 30 mg CaO/I then an analysis of the water is a fundamental requirement. Evaluation of the aggressiveness towards concrete is carried out in accordance with DIN 4030. AQUAFIN-1K is resistant up to attack grading “highly aggressive” (exposure class XA2).

Product Details

Product Application:

Prepare the substrate appropriate to its requirements.

  • Place approx. 1.6 or 6.7 litres of clean water into a clean mixing bucket, mix in as much powder until a homogenous lump free mix is achieved. With a mechanical mixer (approx. 500-700 rpm) a mixing time of approx. 2-3 minutes is necessary.
  • Apply two coats of AQUAFIN-1K by brush or trowel. Only apply the second and successive coats once the one beneath will not be damaged by foot traffic or during application (approx. 4-6 hours at +20° C/ 60%RH). An even thickness is achieved by using a 4 to 6 mm notched trowel followed by smoothing flat. Avoid applying thicknesses greater than 2 kg/m² as a single coat as there is a risk of cracks appearing in the waterproof layer due to the high binder content.
