Polymer Renders: The JPS Way

Polymer renders are the result of the evolution of an ancient building and construction practice that dates back to an era when primitive men plastered their dwellings with mud. The pyramids of Egypt have been finished with a mastery of hard and durable plasterwork that withstood the test of time. The Egyptians used a material known as gypsum, a water soluble material that when dehydrated, turns into a plaster. This was later known as Plaster of Paris.

Rendering systems have evolved since then into several other forms such as cement render, wherein a premixed mixture of sand and cement were laden into cement, brick, stone or mud brick. Cement renders bring texture to the application and is coloured or painted after the application.

Polymer renders, acrylic renders, scratch coat, lime render and brick effect render to name a few. The use of any type of render depends on the existing substrate, the structure's age, colour, texture and finish.

What makes good quality Polymer Renders?
There are two types of render. Internal render ensures a smooth surface, protecting the wall against dust and dirt from getting into the application. Good internal rendering can also protect against vermin and creates a surface that is ready for painting. External render enables resistance from atmospheric conditions such as the possibility of rain water getting into the surface.

The challenge with any render is adhesion. Choosing an effective polymer render requires builders and contractors to understand the temperature, the weather conditions, rainfall measurement and aesthetics.
