Why do basic cement render finishes crack?
Whether it’s a site mixed cement render or a pre-packaged cement render, all cement renders will develop surface cracks over time – an outcome of all cement based finishes once they harden, cure and are exposed to normal expansion and contraction elements from daily fluctuations in temperature. The initial look of cement render with a painted sponge finish is similar to the very popular RSA Finecoat finish Acrylic Texture, but without the durability and lifespan.
