MARCOTHERM PRIMER - Sellador/imprimación con Granos de Arena de Cuarzo de San Marco
Marcotherm is the perfect primer for Classico Marmorino. If you want your Marmorino to behave as it is intended to, this primer is a" must use" . It is the perfect base for Classico , or any of the San Marco aggregate plasters. I will always use this product, check it out for yourself and see the difference.
Did some initial research and got exactly what I wanted. Totally recommend this
