CONCRETE FORM RELEASE AGENT

The unique feature of concrete among all construction materials is its ability to take almost every shape and keep that shape with constant material properties for an extremely long time. The dimensions of that shape are given by the formwork into which the concrete is cast. One of the challenges within the concrete construction process is to prevent adhesion of the hardened concrete on the formwork, while ensuring it remains durable and easy to clean.

By applying the right mold release agent - Sika® Formol - it leads to smooth, dense concrete surfaces with improved durability and aesthetic appearance. It can be used in construction site cast-in-place concrete applications or precast concrete.

Sika® Rugasol® products are formulated to retard or slow down cement hydration on concrete surfaces. This allows for easy removal of cement paste, thereby exposing the aggregate finish. Apart from architectural applications, these products are also used to roughen concrete surfaces for such purposes as casting new adjoining concrete, or even to create a non-slip surface for paths or pool surrounds.

Sika® Rugasol® technologies can be used in:

  • Artificial stone manufacturing
  • Structural concrete
  • Vertical and horizontal concreting joints
  • Precast concrete
  • Pedestrian pathways
  • Exposed aggregate concrete finish
