TRIMFINITY interior composite mouldings suit all your moulding needs, whether you are a do-it-yourselfer or a professional contractor. The 9/16-in X 3-1/4-in X 96-in colonial 322 base interior polystyrene moulding cuts, installs and fills just like wood and MDF moldings. The Trimfinity advantage is it's more durable, resistant to moisture, mold, mildew and pests. Our mouldings are also better for the planet, made of at least 90% recycled polystyrene. Use as is with our pre-finished white surface or easily paint.
