SikaTop®-109 Elasto

CRACK BRIDGING CEMENTITIOUS POLYMER-MODIFIED WATERPROOFING COATING - 2 COMPONENT

SikaTop®-109 Elasto is a two component, crack bridging cementitious polymer-modified waterproofing coating. It is applied to concrete and mortar to prevent water infiltration.

  • Pre-packed mix
  • Easy to use and apply, only requires mixing of both material
  • Flowable consistency
  • Good adhesion on sound substrates
  • Impermeable
  • Good resistance to abrasion and erosion (non-exposed system)
  • No drying or shrinkage cracks if used according to instruction
  • Non-corrosive, non-flammable
  • Non toxic
  • Flexible
  • Good crack bridging capability (up to 1 mm at +20 °C)

Application

Application Information

Mixing ratio

Comp. A (liquid) : Comp. B (powder) = 1 : 1.5 (by weight)

Ambient air temperature

+10 °C min. / +35 °C max.

Substrate temperature

+10 °C min. / +35 °C max.

Pot Life

~30 minutes (at +30 °C)

Pot life is shorter at higher temperatures.
Consumption

Consumption

~ 1.0 kg set/m2/coat (using brush, depending on substrate surface and type of application).
Always ensure waterproof coatings are applied in a minimum of 2 coats.
For areas subject to high water ingress, apply a third coats at ~ 1.0 kg/m².
Application steps

MIXING

  • Pour 90% of component A (liquid) into mixing vessel.
  • Add all component B (powder) and mix until you have slurry of uniform consistency. Add rest of component A and mix again until you have uniform, lump-free mixture.
  • A mechanical slow speed mixer is recommended. Mixing time 2-3 minutes.
 

APPLICATION

On vertical surface use suitable brush with synthetic bristles.
On horizontal surface use rubber slide or push-broom.

   

  • Apply SikaTop®-109 Elasto into prepared substrate with consumption ~ 1.0 kg/m2 per coat. Always apply a minimum of 2 coats.
  • The first coat has to be applied on the damp substrate (pre-wetted).
  • After the 1st coat dry (4-6 hours), apply the 2nd coat with a crosswise direction.
  • Maximum waiting time between first and second coats is 48 hours.
  • Use Sika reinforcement membrane when necessary at corner and detailing area.
  • An additional stripe coat is recommended over cracks, wall/floor intersections, etc. as these locations are where movement is most likely to  be expected in service.

   

IMPORTANT NOTES :
Must use component A (liquid) and B (powder) of SikaTop®-109 Elasto in 1 set, CANNOT be replaced one of them with other material or added with other ingredients (water, cement or sand).
Protect the applied product with screed, tile, or granit.

CURING TREATMENT

Protect the freshly applied product against direct sunlight and strong winds.
Protect the freshly applied product from rain and water splashes until fully hardened. (± 6 hours).

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use.
Hardened and/or cured material can only be mechanically removed.
