Getting the scaffolding right is vital to getting a great finish to the render. Things that need to be considered include scaffold boards, scaffold tubes and the right lift.
The first requirement is for the scaffolding to be one scaffolding board away from the wall. This is because in order to get an even thickness along the whole wall, the scaffolding has to be level in every part. To achieve a good and consistent finish sufficient access is required.
The second requirement is that no poles should be touching the wall. This is important because any tubes that are touching the wall may prevent the renderer from doing their job as they would not be able to get an even finish just like with the scaffold boards. Adding to this, any tubes that are touching the wall may mean that marks are left within the render which will leave an untidy and ugly looking finish which would leave the customer unhappy. Although this would have to be discussed with the scaffolding contractor as this is not always possible as the scaffolding may end up moving.
The last way that scaffolding can affect the render is by not getting the right lifts. An average lift on scaffolding is around 2m high, however, this all depends on the building itself. Each lift should be parallel to the building so the scaffolding may have to be adjusted to cater for this. Getting the right lift is important in order to be able to do the rendering properly. All areas that require rendering would have to be reached comfortable in order to get a level and good finish. Our london scaffolding contractor who we work with generally does a very good job for us, as they are used to our requirements.
