Finishing coating ARGATHERM ULTRAFINE

heat-reflectivefor outdoor usefor indoor use

Short description
Ultrafine finishing skim coat composed of hydrated lime, crystalline micro-sands, marble powders and natural microfibres, designed to create perfectly smooth white surfaces with high breathability.

Product overview
Argatherm Ultrafine is an ultrafine mineral finishing skim coat (grain size 0–0.1 mm) formulated with spherical expanded mineral fillers with a microporous structure, natural microfibres (250 µm) and specific additives. The combination of selected aggregate size and microfiber matrix ensures excellent workability, easy trowelling and strong adhesion to common substrates. Suitable for architectonic interior and exterior finishes where an extra-fine, specular white surface is required.

Where to use
Finishing skim coat for interior and exterior applications. Use Argatherm Ultrafine in combination with Argatherm base skim coats to achieve a perfectly smooth surface on substrates such as Diathonite line plasters and prefabricated concrete panels. High vapour permeability and the antibacterial action of hydrated lime contribute to healthier indoor environments and improved living comfort.
