Do I need a primer? New lime plaster requires either 1 x coat of the Graphenstone L42 Ambient Primer (L42 is a hybrid primer, which contains some acrylic) or a mist coat of Graphenstone Nevada white emulsion (which is a Natural Paint & acrylic free) or a mist coat of the this GCS exterior if you want to stay acrylic free. Existing lime based coatings may be ok without a primer coat but Graphenstone recommend the L42 Ambient Primer as it helps stabilise the surface.
