Sika® Antisol®-181 S

(former MKure 181S)

Silane siloxane resin based multi-role curing, sealing, priming and impregnating protective treatment for concrete

Sika® Antisol®-181 S is a non-degrading, membrane forming liquid based on silane siloxane resin suitable for spray application to freshly poured concrete.
The resultant film retains sufficient moisture in the concrete to ensure full hydration of the cement, essential for optimum strength development. The cured concrete is typically harder and exhibits a dust free surface with a reduced incidence of drying shrinkage cracks.
Additionally, the membrane acts as a primer system for many subsequent surface finishes that do not rely on penetration for substrate bond.
When applied to floors, the Sika® Antisol®-181 S seals and dustproofs the surface, eliminating the primary source of abrasion and enhancing durability. Suitable for use in hot and tropical climatic conditions.

  • Water repellent concrete
  • Application by hand or power-driven equipment
  • Cost efficient by saving time and reducing labour cost
  • Effective in all conditions of humidity and temperature
  • Single application, no further attention is required
  • The finish and colour of concrete are not affected once the compound has disintegrated under the influence of ultra violet light or abrasion

Sika® Antisol®-181 S provides the following beneficial properties to concrete surfaces:
  • Reduces incidence of plastic cracking
  • Ensures achievement of desired strengths
  • Alleviates other costly methods such as hessian-watering, etc.
  • Reduces dusting
  • Minimizes shrinkage

Usage

Sika® Antisol®-181 S is applied to fresh concrete surfaces to form a fast drying, thin, flexible and tough impervious membrane which protects the concrete from rapid water evaporation during initial curing stages, thereby assisting towards obtaining maximum strength, durability and helping towards the elimination of shrinkage cracks and surface dusting.
Sika® Antisol®-181 S is particularly useful in large areas of exposed concrete, such as:
  • Highways, runways and taxiways
  • Aprons and hardstandings
  • Roof decks
  • Retaining walls
  • Pre-stressed beams and piers
  • Bridge decks, etc

Consumption

Consumption

Sika® Antisol®-181 is recommended to be applied at approx. coverage rate of 4.5 – 5.5 m² per litre.
This corresponds to the rate at which Sika® Antisol®-181 S has been tested and at which it attains the claimed degree of curing efficiency. In favourable conditions such as shaded interior surfaces, adequate curing can be achieved with extended coverage rates.
Application steps

APPLICATION

The compound should be spray applied as evenly as possible to the freshly placed concrete.
For horizontal surfaces the Sika® Antisol®-181 S should be applied as soon as the initial surface sheen has disappeared from the concrete face. In the case of formed concrete, the product should be applied immediately on removal of the formwork.
