Spray rendering is often completed in one coat, known as monocouche rendering. It results in a durable, weatherproof layer which is quick to apply. There are different types of traditional rendering, and most are multi-layer systems which are applied by hand. Depending on the condition of the building and other factors such as the local weather and material availability, traditional rendering may be the most suitable choice.
Materialistically speaking, the mix used in both are almost identical; the strict definition is the plastering is carried out on an interior surface, and rendering is carried out on the exterior of the house. Spray applied render can ensure on achieving consistent effective results both on product mix and desired finish to the building
While the precise length of the process will vary from project to project, a typical semi-detached house will typically take around a week. This includes the time to erect and disassemble the scaffold, render curing time and applying the final finishing details. As rendering is carried out on the exterior of the house, the weather can also affect the timeframe.
You usually don't require planning permission to apply external rendering to your home unless it's listed; in a conservation area; and permitted development rights haven't been removed. If you are unsure, you can check with your local planning office.
However, if you are working with a substantial area of the structure, you will need to comply with Building Regulations when it comes to insulation.
The short answer is no; it's not even recommended if it's forecasted to rain. Unless the work area is covered by waterproofed scaffolding, you run the risk of rain weakening the render mixture, resulting in an inconsistent result or even in severe cases, washing the render off the wall.
The most suitable type of render for your project depends on several factors, including your budget, the age and condition of the house and environmental factors such as local climate. For example, lime render is recommended for older buildings as it offers a higher degree of flexibility for buildings which have a lot of movement.

Strictly speaking, nothing is stopping you from using a spray rendering machine indoors. However, it's usually not required unless you are plastering large areas, for example, a hotel lobby. It would be impractical to set up the machine in a residential dwelling where there may not be sufficient space to operate and cause unnecessary stress when the machine is operating.
