SILICATE-BASE WALL SEALANT
MARCOSIL PRIMER is a modified potassium silicate-base sealant designed to seal and consolidate walls before treating with paint or silicate-base coatings.
MARCOSIL PRIMER reacts chemically with the surface via a process called "silicatization". In this way, it consolidates and renders uniform the porosity, enabling uniform results to be achieved.
