The Grain That Carries the Finish
Venetian plaster, microcement, tadelakt, polished lime. Decorative finishes live or die on the grain that carries them. Alliance Silica® supplies the fine and micronised natural silica sand that decorative plasterers and specialist applicators specify when colour has to sit true and a thin-layer finish has to stay crack-free over large, uninterrupted planes.
Fine and Micronised Silica Sand for Decorative Plasters, Polished Finishes and Premium Renders

Alliance Silica® supplies the fine-grade and micronised natural silica sand that decorative plaster and premium render systems are built on. Controlled grain distribution carries pigment evenly, keeps thin-layer finishes crack-resistant, and produces a true flat or burnished finish across large, uninterrupted planes.
We work directly with decorative plasterers, specialist applicators and the interior designers and architects specifying them - matching the grade and grain character to the specific plaster, render or microcement system in use.

The Foundation Beneath Every Decorative Finish
Decorative plasters and premium renders - Venetian plaster, polished plasters, tadelakt, microcement, lime plasters and spray-applied render systems - all depend on a fine, clean, consistent grain. Grain size controls how smoothly the finish pulls, grain shape controls how cleanly pigment disperses, and cleanliness controls whether the finish sits crack-free through its service life.
Alliance Silica® supplies natural silica sand graded and screened for decorative finish systems. No dyes, no chemical coatings, no bulking fillers - the natural colour and grain character carry through into the finished surface, sampled in the specification and delivered to site.
