Plaster Additives & Fillers
This specialised range features plaster Accelerators and Retarders to give you precise control over your plaster set times, alongside PolyCryl® Plaster Polymer—a water-based acrylic liquid additive that dramatically strengthens alpha plasters like Crystacal R to reduce brittleness, chipping, and cracking. Rounding out the collection are high-performance thermal and lightweighting solutions, including Vermiculite and Siniat’s G400E Perlite MicroSpheres, which reduce cast weight without compromising structural integrity.
