Rendering inappropriate surfaces
Render finishes are often the final and most important element in the building process as they define the overall aesthetics of the structure. All too often they are considered as a cover-up for other construction bad practice and poor alignment. Sometimes renders are required to be applied over inappropriate surfaces.
1. Painted or coated substrates
2. Substrates out of plane
3. Dissimilar substrate materials
Treat surface and finish with EWI system
A detailed assessment of the condition and flatness of the substrate surface must be made by the specifier. The assessment should consider whether the surface will allow for direct application of render or if additional mechanically‑fixed render carriers are required. Sometimes the surface will require dubbing out (making level) before rendering can proceed.
