The 128-oz bottle supplies ample material for large panels or multiple canvases, and the product's fluid yet impasto nature means it can both build dimension and accept paint adhesion reliably. For painters seeking heavy-bodied priming that can be tinted and mixed with other Liquitex products, this is a practical, studio-ready choice.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuper Heavy body:\u003c\/strong\u003e Allows for thick, sculptural applications so artists can create raised textures and impasto effects directly in the ground.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface preparation:\u003c\/strong\u003e Seals and adds tooth to canvas, wood, paper, and metal to improve color adhesion for both acrylic and oil paint.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge 128-oz volume:\u003c\/strong\u003e Provides ample product for priming large surfaces, murals, or multiple supports without frequent reorders.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntermixable:\u003c\/strong\u003e Can be mixed with Liquitex Professional acrylic colors and mediums to create tinted grounds and customized primers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid yet viscous control:\u003c\/strong\u003e Reduces viscosity of heavier paints and gels when blended, giving versatility in handling and finishes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConforms to ASTM D4236:\u003c\/strong\u003e Rated safe for educational use, making it appropriate for schools and workshops.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis medium suits professional and advanced hobby painters who work at larger scales or who want to incorporate textured, sculptural grounds into their paintings.
