Koster Thermal Restoration Plaster 12.5kg
Koster Thermal Restoration Plaster is a pure mineral insulating plaster with good thermal insulation properties that is free of plastics. It prevents mould growth and can be used instead of restoration plaster.
Koster Thermal Restoration Plaster is used for the pollutant-free restoration of existing masonry and is suitable for heavily moisture and salt-contaminated substrates. The compressive strength is comparable to other thermal insulation plasters. Due to the use of approx. 50% high-quality recycled raw materials, this plaster is ecologically sustainable in several aspects. Due to its pore structure and water-repellent properties, the Koster Thermal Restoration Plaster allows the masonry to dry and desalinate without damage, even at high salt levels. The Koster Thermal Restoration Plaster is not a sacrificial plaster but is used for permanent restoration, it is highly open to diffusion and improves the indoor climate.
Uses
For the repair of masonry damaged by moisture and salt, especially after the installation of a horizontal barrier. The installation of a horizontal barrier and the Koster Thermal Restoration Plaster is suitable for all moisture and salt levels in masonry. For improving the insulation value of the masonry and for use against mould growth.
Application
Koster Thermal Restoration Plaster is mixed with approx. 5.0 litres of water per 12.5 kg bag to a workable mortar. The water quantity is placed in a mixing vessel. The powder is to be added in slowly while continuing mixing. We recommend a double compulsory mixer. A mixing time of 3 minutes must be ensured. The fresh material is to be applied directly. The plaster is applied in one or more layers. The plaster thickness is min. 1 cm. The maximum layer thickness on the surface is 5 cm. From 3 cm and in unfavourable weather conditions, work must be carried out in several layers. In case of different system compositions, please contact our technical department. After levelling the substrate’s roughness and applying the Koster Restoration Plaster Key, the first layer of the Koster Thermal Restoration Plaster is applied and levelled with a trowel or straight edge to a layer thickness of 3 cm. Immediately afterward, the Koster Glass Fibre Mesh is embedded into the surface. After a minimum of 60 minutes, the second layer of Koster Thermal Restoration Plaster is applied in a layer thickness of max. 2 cm and also levelled with a trowel or straight edge. After sufficient curing, the plaster is rubbed off with a wooden or plastic board and finally finished with a sponge board.
Koster Thermal Restoration Plaster can be rubbed off after a period of approx. 1-3 hours, depending on humidity and temperature. After the first rubbing off, do not moisten the plaster again, and rub off a second time. Alternatively, the plaster can be smoothed with a grate float after hardening.
For surface smoothing in interior areas, Koster Hydrosilicate Adhesive SK can be applied in a layer thickness of up to 2 mm. The application can be carried out after 24 hours at the earliest. In case of deviating layer build-up, please contact our Technical Service.
Aftertreatment
In general: Allow one day drying time per mm plaster layer thickness. The Koster Thermal Restoration Plaster must be recoated with systems that are open to diffusion.
Consumption
Approx. 5 kg / m² per cm layer thickness
