Bring the timeless look of traditional plaster moulding into your next interior project — without the complexity of traditional plasterwork.
TRIMROC mouldings are crafted with a high-density polystyrene base, cementitious basecoat, and smooth acrylic plaster finish, giving you crisp architectural detail with a clean, refined look. Designed for dimensional stability, TRIMROC helps resist warping, shrinking, swelling, and cracking over time.
From crown moulding and ceiling trim to beams, coffered ceilings, light coves, medallions, and corner wraps, TRIMROC offers interior finishing options for both new builds and renovations.
Available through Timberstone Distribution.
