GFRC Finishes

The finish of a piece can make something go from ordinary to extraordinary. We set the highest standards for all our materials – we recognize that you have choices when specifying, and that you turn to Tournesol Siteworks for quality, beauty and durability.

We have attempted to recreate our colors, finishes and appearances true to life. However, the color and appearance of a finish will depend upon your monitor and/or printer. Contact your salesperson for a physical sample(s) to verify that it will meet your needs.


GFRC Lightweight Concrete Materials

GFRC (glass fiber reinforced concrete) has the look and durability of concrete without the associated weight. By adding long-strand, alkali-resistant glass fibers instead of rebar to the conventional concrete, we increase the strength of the material and decrease the thickness. Decreasing the thickness 60% (from typically 3” in cast concrete to 1” or less in GFRC) directly reduces the weight by the same amount. 


GFRC Lightweight Concrete Textures

Versatile GFRC lightweight concrete textures range from the rustic to the refined. Our finishes feature natural quartz and mica sands, and the durable finishes can be refinished and repaired on site as required. The Travertine, Sandblast, Acid Etch and Granite finishes are variations on natural concrete finishes, while Natural Sand and Fine Grain rely on applied paints and texture, similar to FRP finishes. We send out a color/texture sample as a submittal with every order confirmation to make sure that you are getting what you expect. All finishes are shown in Shark, but are available in any GFRC colors.


Tier 1

Sandblast – A medium sand blast surface that reflects the texture and color of natural stones like limestone and sandstone. Muted shades and some small, colored aggregate is exposed.

Natural Sand – The texture and feel of stucco, with a uniformly painted finish giving the primary color depth; a natural sand is applied to finish the exterior.

Travertine – A puckered, rustic surface with irregular natural voids. 


Tier 1 GFRC


Tier 2

Acid-Etch – A nearly smooth, fine sand finish that is consistent, elegant and rich looking. Especially attractive for benches and table products.

Granite – Sandblast finish with contrasting aggregate colors. Especially durable and low-maintenance for high-traffic areas.

Fine Grain – Similar to our Natural Sand finish, with a stucco-like texture. The sand is over-coated with any Tier 1 or 2 FRP color, similar to FRP T-1 finishes.  

Tier 2 GFRC

GFRC Lightweight Concrete Colors

We used our FRP Fiberglass colors as the starting pigments for the white cement we use on the surface coat, but from there the natural materials take over.

Because we’re using quartz and mica sands, there is always a beige tone to any GFRC color. Samples are below shown in Acid-Etch texture, but other texture and color samples are available upon request. Granite texture is only available in Shark, Chaparral, White and Sahara colors.
