Spiver PRIMER RV 15L | Adhesion Primer for Plaster & Stucco
Spiver PRIMER RV is a professional rough-textured adhesion primer that gives smooth, low-absorbent surfaces the grip they need to hold decorative plasters, including marmorino. Ideal for concrete, cellular concrete, drywall, gypsum and ceramic tile. Made in Italy by Spiver Colorificio.
Why you need Primer RV
Smooth or low-absorbent substrates — concrete, cellular concrete, drywall, gypsum, sanded ceramic tile — are notoriously hard for decorative and lime-based plasters to bond to, leading to peeling and cracking finishes. Spiver Primer RV solves this by leaving a rough, sand-like texture on the surface that acts as a mechanical anchor for the plaster or marmorino applied on top.
Composition
Acrylic microemulsion, special surfactants, quartz granules, additional additives.
How to apply
Apply directly with a brush or roller after diluting with 50% water. Keep the mixture stirred continuously so the quartz granules stay in suspension.
