Sovereign Renderlite Renovating Plaster is ideal for any plastering situation. Its performance characteristics, which allow walls to breathe but prevent the movement of liquid moisture and salts, make it particularly suitable for use on damp walls or after the insertion of a chemical DPC.
Sovereign Renderlite is an easy to apply internal plaster; it is breathable but will not allow the passage of salts through to the surface. Renderlite also has excellent thermal qualities, with a U value much lower than either sand, cement renders or gypsum based plasters. This makes it particularly useful where condensation may be a problem, such as cold external walls or after tanking basements with Sovereign Hey’di K11.
Benefits and Features
- Used in conjunction with the Hey’di K11 Tanking System
- Prevent the movement of liquid moisture and salts
- Increase the surface temperature
- Reducing the chance of condensation
Preparation
When used after a chemical DPC remove timber skirtings, dado rails and radiators. Hack off old plaster back to the brickwork to a height of 300 mm above the last signs of damp, or 1 metre above the level of the DPC, whichever is the higher. Rake out mortar joints and hack the brickwork to provide a key. If dry rot is present then treat the area with Sovereign Fungicidal Wall Solution Extra as detailed in our technical literature.
Mixing
This can be done either by hand or machine. When using a machine mixer do not mix for more than 5 minutes. To mix by hand with a plasterers whisk then add ½ the contents of the bag to 12.5 litres of water and mix to form a thin slurry. The remainder can then be added. Once mixing is complete allow to stand for 15 minutes before use.
Coverage
3.5m² @ 10mm thickness per 25kg bag.
Finishing
Once the final coat of Renderlite Renovating Plaster has set, usually 24 hours it is ready to receive the finish coat. Sovereign recommends the use of Sovereign Renderlite Finish Plaster, to a depth of 1.5 – 3 mm be applied (see TDS 87). When the Renderlite system is used after the insertion of a DPC then it should be left as long as possible before the application of a paint coating, wallpapering must be delayed for 6 months
