Restoration render

Durable special renders for the optimum protection of the building

Buildings change. Dirt and air pollutants collect on the façades over time. Moisture can penetrate. If renovation work is scheduled the façades are usually cleaned, but sometimes this is not enough.

Over the years salts build up that cannot be removed by cleaning. If the render is replaced in these cases, the undercoat and the top coat must be able to deal with this damage potential as sustainably as possible.

The task of restoration render systems is to ensure a dry and efflorescent plaster surface for a long period and offer the brickwork long-term protection by allowing the salts to be stored in the plaster and therefore removed from the brickwork.

To achieve this, restoration render systems work in one of two ways:

  • Restoration renders are water repelling but also highly breathable. This relocates the evaporation level from the surface into the plaster cross-section
  • Undercoat renders assume the function of a storage layer. Liquid moisture and the soluble salts it contains should be able to penetrate the render and leave the salts
    in the undercoat when the restoration render diffuses

Remmers Restoration rRnder systems are optimally suitable and proven. The permanently water repelling and highly breathable restoration render allows the brickwork to dry out, but keeps back the salts so that no efflorescence occurs. If there is a high level of salt, the surface can be equalised with a (pore) undercoat render that allows the salts to crystallize without causing damage. Alternatively, Remmers compress render, which is breathable and capillary-active, can be applied as a real dehumidification render. It ensures permanent moisture regulation and with 60% more pore volume, it offers enough space to store salts.

Active principle of the restoration render - single-layer

Relocation of the evaporation level for the moisture in the masonry from the cleaning surface into the render layer. Restoration renders are water repelling and highly breathable at the same time.

Active principle of the restoration render - dual-layer

Salts coming from the masonry are stored without damaging the render. The undercoat render is not water repelling so that, thanks to 50% more pore volume, the salts can penetrate and the render offers enough space to store the salts without causing damage.

Active principle of the compress render

In contrast to restoration render, there are no water repelling properties to ensure dehumidification and desalination. The render receives an even larger pore volume to store / or let through as much salt and moisture as possible, and discharge them quickly and efficiently to the air.
