Xtreme Countertop Terrazzo Mix

Discover the dual-component XS Concrete Terrazzo Mix, perfect for creating stunning, polished terrazzo surfaces. This innovative mix simplifies traditional precast terrazzo construction, eliminating the need for reinforcement steel and allowing for thinner, faster-produced pieces. Enhanced with modern fiber technology, it forms a stronger, denser, and more flexible composite. With limitless design possibilities through a variety of colors and decorative aggregates, XS Terrazzo is ideal for countertops, mantles, shower surrounds, wall panels, furniture, and more. Incorporate recycled materials to earn green points and contribute to sustainable building practices.

(Varies based upon aggregate selection)

MIXING

1. Utilize a mortar mixer (preferred with a horizontal helical [spiral] shaft) or a concrete mixer of sufficient size to allow the free vertical fall of product while mixing.

2. Maintain the ratio of 2 gal (3.8 L) XS Precast Modifier per bag of XS Terrazzo + aggregate loading within the below ranges: a. A minimum of 50 lbs. (22.7 kg) of aggregate must be added per bag of XS Terrazzo. Of the 50 lb. (22.7 kg) aggregate load, 20% of load or 10 lbs. (4.5 kg) must be fine aggregate, size 00 or smaller. b. A maximum of 80 lbs. (36.3 kg) of aggregate may be added per bag of XS Terrazzo. Of the 80 lb. (36.3 kg) aggregate load, 20% of load or 16 lbs. (7.3 kg) must be fine aggregate, size 00 or smaller.

3. Thoroughly mix XS Precast Modifier.

4. Place total amount of XS Precast Modifier for the entire mix into the mixer.

5. Add all Color Packs to the modifier (if desired) and start mixer.

6. While mixer is running add one XS Terrazzo bag at a time.

7. Add decorative aggregate to running mixer.

8. Additional water may be added, not to exceed 40 oz. (1.2 L) per bag of XS Terrazzo

9. After last bag is added, allow all material to thoroughly mix for 2 – 3 minutes. Visually inspect entire load to ensure that all fiber and aggregate is blended.

APPLICATION

Although not limited to it, the most common method of placement simply involves pouring XS Terrazzo directly from the pail or mixing vessel into the form or mold.

DEMOLD

In warm weather 4-6 hours may be appropriate to de-mold. Cool temperature or pieces with extreme texture will require overnight drying. XS Terrazzo should not be left in the mold past a 24 hour period, as curling of the piece is likely. A freshly de-molded sample should be handled similar to granite or natural stone, and should be well supported above the work surface to allow the free flow of air around the piece.

GRIND/POLISH

1. Grind precast sample as soon as practical. Use of a planetary grinder is recommended. Allow a minimum of 8 hours cure time.

2. Begin wet grinding with 50 grit diamond pad to expose aggregate.

3. Proceed to wet grind with 100 grit diamond pad.

4. LD1800 may be utilized with wet 100 grit grind to densify and fill pinholes with resultant color match slurry. For specific directions on LD1800 refer to its TDS.

5. Allow LD1800 and slurry to dry. Proceed with 200 grit and if any pinholes are still present add more LD1800 and continue grinding.

6. Remove any excess dried slurry with the 200 grit.

7. Proceed through 400 grit polish. Product responds best to a dry polish

8. If sealer is to be used do not polish past 400 grit, as a measure of profile must be maintained for sealer adhesion.

9. If desired and sealer is not used, one can continue polishing through 800 grit and beyond, however, such a piece is subject to staining.

SEALING

XS Terrazzo pieces are completed by sealing. Two distinct sealers have been created for XS Terrazzo:

• XS-327 - hybrid water based polyurethane available in matte and gloss finish.

• XS-PC12 - hybrid solvent based polyurea, color enhancing, high gloss mirror finish. For specific directions on sealing refer to the appropriate TDS.
