When to Specify Breathable Renovation Plaster
Breathable renovation plaster is a sensible choice for renovation projects where walls need to dry naturally rather than be sealed in. On older masonry, damp walls can hold residual moisture, salt contamination and even hygroscopic salts, so a breathable plaster with a porous structure can help moisture evaporate naturally instead of sitting behind impermeable finishes.
We would usually look at renovating plaster where rising damp, trapped moisture, salt migration or black mould have already affected the plaster finish. It can also suit flood damaged properties, basement walls and other areas where control dampness matters, especially after a new damp proof course, dpc installation or other damp proofing treatments have been carried out.
On renovation work involving historic buildings and most traditional background materials, a traditional lime plaster is often a better fit than conventional plasters. Where clients are comparing limelite renovating plaster or wykamol renovation plaster, Romana Intonaco gives you a Licata renovation plaster option based on NHL 5 lime, designed to create breathable masonry surfaces and act as a preparatory layer within the Naturalis line.
Key Features of Romana Intonaco NHL 5
Romana Intonaco is designed for breathable renovation plaster work where substrate compatibility, vapour movement and a dependable plaster finish all matter. Key points include:
NHL 5 Hydraulic Lime Base: This renovation plaster uses traditional raw materials and is historically compatible, making it well suited to traditional background materials and lime plaster specification work.
Fibre Reinforced Mix: The product is fibre reinforced, which supports flexural strength and helps control shrinkage across the backing coat or scratch coat during interior plastering and external renovation projects.
Breathable Porous Structure: Its high transpiration performance makes it ideal in dehumidifying cycles, helping surfaces dry naturally and helping to control dampness passing through masonry. That matters where damp treatment aims to reduce mould growth, black mould and salt migration.
Smooth or Rustic Application: Romana Intonaco is smooth and soft in use, so it can be applied neatly or left with a more rustic plaster finish. It also provides a sound base before finishing plaster, decorative finishes or breathable paints are applied.
Renovation Mortar Classification: The product conforms to Class R under UNI EN 998-1 as renovation mortar, giving specifiers and contractors a reliable solution for renovation plaster work.
Suitable Surfaces for Breathable Renovating Plaster
Romana Intonaco can be used on brickwork, stone, clay bricks, tuff, mixed masonry, reinforced concrete and concrete, both indoors and outdoors. That gives it a broad role across renovation projects where a breathable plaster is needed instead of permanent and impermeable finishes or non breathable paints.
For internal walls that have suffered from moisture content issues, salt contamination or old plaster failure, this renovating plaster can support a more suitable preservative approach than simply covering the surface. Used as part of a suitable system, it helps create an ideal decorating surface for breathable paints and other decorative finishes, without pushing trapped moisture further into the wall.
