Algae Moss - Quartzite
Professional advice and the right Lithofin products for your quartzite
MediumAlgae and moss growth on stone is a common outdoor problem, particularly in damp, shaded areas. Algae appears as green, red, or black discolouration on the surface, while moss forms thicker cushion-like growths in grout lines and textured areas. Biological growth occurs when moisture, shade, and organic nutrients create favourable conditions.
