SikaTop®-209 EG

FLEXIBLE WATERPROOFING MORTAR

SikaTop®-209 ES is a 2 component flexible waterproofing mortar, cement based, with selected aggregates and modified polymers.

  • Low modulus of elasticity, thus achieving good flexibility, reducing the risk of cracking and improving the ability to bridge shrinkage cracks and microcracks  
  • Waterproof and water vapour permeable
  • Withstands both positive and negative pressure
  • Predosed
  • Excellent adhesion on healthy substrates including concrete, cement mortars, stone, bricks, etc.
  • High resistance to de-icing salts and freeze-thaw attack
  • Stops the progression of carbonation ▪ Good crack bridging properties
  • Approved for contact with drinking water

Usage

It can be used for waterproofing and protection of surfaces where flexibility is required in order to bridge small cracks.
Some of the most common places where it can be used are:
  • Tanks, swimming pools, canals or other elements intended to contain water, whether buried or not 
  • Interior waterproofing of basements
  • External waterproofing of underground walls Repair and protection of surfaces exposed to the action of frost and dicing salts: bridges, terraces and roof overhangs, cornices, etc.
  • Protection of concrete surfaces in marine environments
  • Waterproofing in contact with drinking water

Application steps

MIXING

Mixing shall be carried out preferably using a low speed (600 rpm) electric mixer.
For this purpose, in a wide mouth and bottom container, pour component B (powder) over component A and mix for 2-3 minutes until a homogeneous mass is obtained.

APPLICATION

The application can be done by trowel, brush, long hair roller or by spraying. The projection equipment will be of type Wagner PC 5, Turbosol T6, Putzmeister gun, etc. The SikaTop®-209 EG can be installed with or without reinforcement.
Without reinforcement:
If a notched trowel is used, with teeth of 3-4 mm, the first layer is applied with the toothed edge and the second with the plain edge, following the direction of the grooves.
The second layer of mortar should be applied when the first has hardened sufficiently (4 to 6 hours at 20 °C).
If a brush, roller or spray is used for the application, apply two coats waiting for the first to harden before applying the second.
SikaTop®-209 EG will extend as evenly as possible, avoiding accumulating material in corners, cavities or slits where cracks may appear.

With reinforcement:
SikaTop®-209 EG coatings armed with Sika fiber glass 107, an anti-alkaline fiberglass mesh, are capable of absorbing certain movements that may occur in the element on which they are applied, as well as acting as a bridge in the event that the support presents shrinkage cracks. The reinforcement must be carefully placed, avoiding any air occlusion due to the formation of folds or bags in the fiberglass mesh. The fiberglass mesh is joined by overlapping with a width between 3 and 5 cm.
The amount of SikaTop®-209 EG to be applied must be the necessary amount to cover the entire reinforcement.

CURING TREATMENT

Measures should be taken to prevent the SikaTop®- 209 EG from drying out too quickly by using polyethylene sheets, wet sackcloths or Sika® Antisol® E curing agent.

CLEANING OF EQUIPMENT

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