1kg of fine powder 150 mesh, ideal for renders, stucco, venetian plaster, and for some acrylic binders this is easier to mix in that fine powders and has less water demand so contracts less on drying so ideal for this use.

Opacity Effect:

  • In Oil/Resin Systems: Coarse particles act like tiny glass beads or quartz crystals. Because light passes straight through large single crystals without much scattering, coarse marble dust in oil or resin appears almost completely translucent or greyish, looking like wet sand or ice. This is used to build up empasto effects - it reduces sag 

  • In Water/Plaster Systems: It provides structural body and tooth, but offers some opacity

Water-Based BinderResult with Marble PowderWhy?
Standard PVA / Wood GlueOpaque WhiteHigh filler-to-binder ratio traps air spaces upon drying.
Matte Acrylic Paint MediumOpaque / Semi-OpaquePre-formulated matting agents and porous structure maintain light scatter.
Casein Binder (Milk Protein)Highly Opaque WhiteDries to a porous, brittle, chalky finish that reflects full light.
Water-Based Acrylic Varnish (Gloss)Translucent / ClearContinuous clear resin seals all gaps; matches refractive index.
Water-Based PolyurethaneTranslucent / GreyishHard, dense resin matrix eliminates light-scattering air voids.

Weight will be about a little over 1kg if ordering 1kg and will be around 1.9kg if ordering 2kg to keep it below the royal mail medium parcel rates.
