Preparation based on new substrate installations.
Once the substrate is deemed ready for plaster then the main contractor can continue to fix the internal linings, this is so that the main contractor can minimise the chance of any damage to the external plaster cladding that may be caused from the fixing process of the internal linings.
Preliminary Checks
Check should be made using a straight edge to ensure the wall is flat, plumb and true. Any irregularities should be taken out by straightening using a rasp.
Builder Supplied Flashings
Make sure all builder-supplied flashings are in place. The architectural drawings provide a list of possible flashings.
RCS Flashing Installation
Refer to the flashings as outlined within the Resene Construction Systems Specification
Control/Expansion Joint Setouts
For more information about control joints refer to the technical note on the Resene Construction webpage at the following link https://reseneconstruction.co.nz/control-joints/
The main contractor/substrate installer is responsible for all control joints, which must comply with the substrate supplier’s specifications.
Clean Surface
When the substrate has been left for a period of time, dust and dirt may build up on the surface. This contamination must be removed prior to render application.
Masking
Before applying the render, masking must be applied to all joinery, pipes, roofs, and all areas likely to be marked by the render. Use drop cloths and ground covers to keep the working areas clean.
Colour selection
For more information about light reflectance values refer to the technical note on the Resene Construction webpage at the following link https://reseneconstruction.co.nz/light-reflectance-values/
