SikaTop®-109 Elasto

CRACK BRIDGING CEMENTITIOUS POLYMER-MODIFIED WATERPROOFING COATING

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

  • Good crack bridging capability (up to 1 mm at +20 °C)
  • Pre-batched components
  • Mixes and applies easily
  • Easily applied by roller or brush
  • Good adhesion to sound substrates
  • Impermeable
  • Increased frost and salt resistance
  • Decreases carbon dioxide penetration
  • Non-toxic, same as cement
  • Flexible
  • Resistant to freezing and thawing (-10°C)
  • Economical
  • Air cure

Application

Application Information

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. Cover material container when not in use.
Consumption

Consumption

Minimum 2 coats at approximately 1.0 kg/m² per coat. For areas subject to high water ingress, apply a third coats at 1.0 kg/m².
Always ensure waterproof coatings are applied in a minimum of 2 coats.
Application steps

MIXING

Under normal circumstances, when the full quantities of both parts are mixed together, a creamy consistency will result. Mix in a clean container by slowly adding the powder part to the liquid part and stirring with a low speed mixer.

APPLICATION

Whilst the substrate is still damp but free of standing water, apply the first coat by brush, roller of squeegee, working the material well into the surface to achieve full bond.

Allow 4 – 6 hours (+30 °C) for the first coat to cure before applying the following coats.

For large areas, SikaTop®-109 Elasto can be applied by spray using a suitable worm type mixer/pump.
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.

 

CLEANING OF EQUIPMENT

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