High-Performance, Breathable Finishing Plaster for Damp-Proofed Walls
Sovereign Renderlite Finish Plaster is a gypsum-based finishing plaster designed as the final coat over Sovereign Renderlite Renovating Plaster or other suitable backgrounds. Once cured, it forms a hard, breathable surface that resists salt migration, making it ideal for use in damp-proofing systems.
Key Features & Benefits
-
Breathable Finish: Allows moisture to evaporate, reducing condensation and mould risk.
-
Salt Resistance: Prevents the passage of hygroscopic salts to the surface.
-
Excellent Adhesion & Impact Resistance: Durable and hard-wearing for internal walls.
-
Extended Working Time: Up to 80 minutes pot life for improved usability.
-
Smooth Application: Finishes cleanly at 1.5 to 3 mm thickness.
Product Specifications
-
Form: Powder
-
Colour: Dries off-white
-
Pack Size: 25 kg
-
Coverage: Approx. 12.5 m² per 25 kg bag at 1.5 mm thickness
-
Shelf Life: 6 months when stored dry and unopened
-
Suitable Backgrounds: Sovereign Renderlite Renovating Plaster, Ready Render, sand/cement backgrounds
-
Unsuitable For: Plasterboard or highly glazed surfaces
System Compatibility
Sovereign Renderlite Finish Plaster is designed as the final layer in the Sovereign Damp-Proofing and Replastering System. It should always be applied over a compatible backing coat such as Sovereign Renderlite Renovating Plaster, Ready Render, or a sand/cement mix incorporating Sovereign SBR.
This system is typically used after the insertion of a chemical damp-proof course (DPC) and provides a breathable, salt-resistant solution for replastering salt-contaminated walls.
Typical System Sequence:
- Install damp-proof course (DPC)
- Remove salt-contaminated plaster
- Apply Sovereign Renderlite Renovating Plaster
- Finish with Renderlite Finish Plaster (1.5–3 mm)
- Delay decoration to allow full drying and salt migration
Application Guidelines
- Ensure the background plaster is fully cured and dust-free.
- Mix powder into clean water, allow to stand for 5 minutes, remix as needed.
- Apply at 1.5–3 mm thickness using a suitable plastering trowel.
- Avoid over-polishing to maintain breathability and compatibility with finishes.
- Allow plaster to fully dry before decoration.
Limitations & Drying Guidance
-
Not for use on: plasterboard, previously painted surfaces, or any substrate requiring a polished or glazed finish.
-
Not suitable for exterior applications; Renderlite Finish is an internal-use-only product.
-
Drying Times: Allow 7–14 days (depending on conditions and thickness) before painting. Maintain good airflow to accelerate drying. Avoid forced drying methods.
-
Post-DPC Use: If applied after a new damp-proof course, delay paint application as long as possible. Wallpapering must be postponed for a minimum of 6 months.
Usage & Safety
- Contains cement and lime—may cause skin, eye, and respiratory irritation.
- Wear gloves, goggles, and a dust mask during mixing and use.
- Ensure good ventilation in the work area.
- In case of contact with eyes or skin, rinse thoroughly with clean water and seek medical advice if needed.
