Anthracite Mastic Grout Filler | Panel Stone Finishing Accessory

Anthracite Mastic Grout Filler – Panel Stone Finishing Accessory

The Anthracite Mastic Grout Filler is part of the Panel Stone finishing system – a range of specially formulated paints, grout fillers, and ageing products designed to work with Panel Stone architectural wall panels to create the most realistic, convincing stone or brick wall effect possible. For filling grout lines in dark Panel Stone installations.

The Panel Stone paint and grout system allows installers and homeowners to customise the colour, tone, and aged character of installed Panel Stone panels to match their specific design requirements – from fresh, clean brick tones to deeply weathered, aged stone effects that make it virtually impossible to distinguish installed panels from genuine masonry materials.
