Cement render
Traditional cement render is commonly applied to suitable masonry substrates. Correct mixing, preparation, thickness, curing and weather conditions are important for a consistent result.
Acrylic render
Acrylic-modified products can provide additional adhesion and flexibility and may be specified across a wider range of compatible prepared surfaces. The complete manufacturer system still needs to be followed.
Which one is better?
There is no single best product for every wall. The right choice depends on the substrate, previous coatings, movement risk, exposure, desired finish and the compatible system available for that application.
Start with an assessment
Before choosing a product, inspect the wall for moisture, contamination, cracking, loose coatings and movement points. This avoids selecting a finish before understanding what must support it.
This guide provides general information. The correct system and scope depend on the condition of the individual property.
