Features & Benefits


  • Suitable for:
    • Tanking of basements
    • Sealing of tanks and ducts
    • Coating of brick and blockwork structures
    • Lining of storage tanks for potable water
  • Mixed with water on site and applied by brush or spray
  • Special mix design produces excellent adhesion to construction surfaces
  • Safe to apply on damp substrates



Preparation


  • All contact surfaces must be clean and sound
  • Remove all loose material, laitence, dust and any previous coating
  • Tap off water pressure where necessary and cut out a 20mm x 20mm fillet at the junction of the wall and the floor
  • Repair any existing cracks and fractures with Aquaplug or FS Mortar as necessary
  • No priming is necessary
  • On dry surfaces, to assist the coating in fully wetting out the substrate, this background should be dampened



Mixing


  • Water requirement to produce the coating is 7.5 to 8.5 litres per 25 kg of dry material
  • Pour the required quantity of water into a suitable mixing vessel
  • Slowly add the powder to the water whilst continuously mixing
  • Mechanical mixing is recommended using a slow speed high torque drill with a Mortar Stirrer
  • Mixing should be continued for three minutes after all the powder has been added to the mixing water to obtain a “creamy” consistency



Application


  • Eproseal is applied in two coats
  • Brush or spray apply the first coat in a horizontal direction down to the fillet level
  • After 24 hours seal fillet with Aquaplug leaving weep holes free
  • Apply a second coat of Eproseal in a vertical direction covering the fillet with the coating
  • Remove weep hole taps and seal with Aquaplug
  • If leaks occur, drill 12mm holes adjacent to the leak and seal with Aquaplug
  • Do not retemper stiffened material
  • Eproseal should not be applied to frost filled surfaces or when temperature is 5°C and falling
  • In warm or windy conditions, mist spraying may be used to compensate for moisture loss
  • In tanking applications a through flow of air is required to prevent condensation
