Hi. I am a customer in need of some advice please, hope its ok to post here but Iwanted professional input rather than "google"! I've just had my new build rendered - ecorend on cement board. Scaffolding has just come down so now I can see it properly. Overall the job looks great but there are 2 very visible seams - 1 small on the front elevation and 1 large on the back. All the rest (large surface area) is seamless. Hard to photograph but they are very visible. Before I talk to the builder next week I would be really grateful for some info so I don't feel out of my depth. Why has this happened? Is this usual? Can it be easily fixed? Thanks
