XS Terrazzo Mix (GFRC)

Xtreme Terrazzo Mix
ADDITIONAL INFORMATION
DESCRIPTION

SureCrete's XS GFRC Terrazzo Mix is a dual-component precast concrete bag mix to which decorative aggregate is added and later exposed to create the unique, polished look of terrazzo.

It greatly reduces the materials and labor required to construct traditional precast terrazzo. No reinforcement steel is required, thinner precast pieces are routine, and quicker production times including grinding and polishing are accomplished. A stronger, denser and more flexible cementitious composite is created by combining cutting-edge technology with modern fiber advancements. It demolds in 6 hours and can be polished in 8. It delivers a green solution to concrete fabrication by taking a 50-150% recycled content load.

With it's increased strength, SureCrete's Terrazzo mix allows for much larger pours and finished pieces without the worry of it becoming overly brittle, as is typical with aggregate-filled concrete casted pieces. And with the demold times available with any in the Xtreme Series, this product helps those professional precast fabricators looking to create a multitude of precast terrazzo pieces without being slowed down by typical cast concrete set times.

CHOOSING YOUR AGGREGATES:

If using sand or a #1 aggregate (⅛" - ¼"), a ratio of one part sand to one part Terrazzo mix should be followed. Up to 50 lbs. of sand may be added.

If using #1 (⅛" - ¼") aggregate or greater, you may load the mix with up to an additional 80 lbs. of aggregate.

20% of the total aggregate load must be fines (smaller than #1).

Up to 40 oz of additional water may be needed per bag if mix seems too thick. When using porous aggregates such as granite or natural stone more water may be needed because the aggregate will wick moisture out of the mix. In some cases soaking the aggregate in water before use is helpful.

CAUTION:  Avoid using aggregates that are weak, flaky or not dense enough to be ground, such as: micas, shale and other soft aggregates. These type of aggregates will "wallow" out, rather than polish, during the grinding process. The result will be an area that has slurry in it rather than aggregate.

Ferrous aggregates may look beautiful for a time. However, without proper surface sealing, they may rust.

Sand or rock are absent from this terrazzo mix. Also, each bag requires 2 gallons of XS Modifier, sold seperately.


HOW TO USE:

>> In a 10-gallon bucket, pour in both containers of XS Modifier and any powder colorants you want to use to integrally color your mix, and mix thoroughly, slowly adding the XS Precast dry contents from the bag.

>> Slowly add in aggregate while mixing. 20% of aggregate load must be fine aggregate, size 00 or smaller.

>> In an upside-down, reversed mold on a flat surface (typically Melamine or a similar material is used as a base), simply pour in your freshly mixed XS Terrazzo to desired thickness.

>> While wearing gloves, use your hands to push material around inside the mold to verify that there are no air pockets or voids.
In warm weather, allow 4-6 hours before removing from the mold (in extreme cold temperatures or for a very thick pour, allow to set overnight).

>> Once de-molded, use SCR, diluted at 3:1 with water, to clean your new surface.

>> If there are any small pinholes in your surface, utilize our XS Slurry mix to fill.

>> If you desire any additional color or accents, now would be the time to apply a stain like EcoStain.

>> Your new XS Precast surface is now ready to receive a coat of sealer!


FREQUENTLY ASKED QUESTIONS:

WHAT IS TERRAZZO?

Terrazzo refers to exposed aggregate in a ground cementitious or epoxy base, creating a one of a kind aesthetic appearance. The Terrazzo surface is sealed or polished depending on its intended use.

WHERE CAN I FIND CEMENT BASED TERRAZZO IN MY HOME OR COMMERCIAL PROPERTY?

Cement-based or concrete Terrazzo is very popular. Due to advancements in the ability to protect it properly with state-of-the-art coatings, Terrazzo can be found in: Kitchens for countertops, focal points or back splashes; Bathrooms for shower walls, shower pans, wall tiles, vanities, sinks. The Xtreme Series Terrazzo is also finding its place in fireplaces, surrounds, mantels, hearths and entertainment centers.

HOW DO I MAINTAIN MY CEMENT BASED/CONCRETE TERRAZZO PIECE?

Maintenance for your concrete terrazzo surface is very simple. Non-abrasive household cleaners that are already found within your home or business are all that are needed. Wiping your piece down every few months with SureCrete's SureFinish will keep it looking brand new for years. Should the top become damaged or the surface jeopardized, resealing the surface is a non-invasive procedure. A typical 80 square foot kitchen requires a technician just a couple hours to prep and reseal an existing piece. That piece will then be out of commission for 24 hours until it can be put back into light duty use.

HOW OFTEN WILL I HAVE TO RESEAL MY CEMENT BASED/CONCRETE TERRAZZO PIECE?

Chances are pretty good you will never have to reseal your Xtreme Series Terrazzo piece. There is a comforting feeling knowing the opportunity exists to be able to do so should it be deemed necessary. With so many other surfacing solutions available, once the surface becomes jeopardized it must be replaced. This is not the case with the Xtreme Series Terrazzo. It can last a lifetime!

DOES CONCRETE TERRAZZO STAIN?

Unprotected cement-based or concrete Terrazzo can stain. A properly sealed Terrazzo countertop has a very small chance of becoming stained, which makes it a very popular choice. As with anything, proper care will ensure that your concrete terrazzo surface will last a lifetime.

There are 2 methods of protecting Terrazzo. The first is with a repellant which is recommended for non-work areas. This is the most common and typically what people are used to seeing as being called Terrazzo. The second method of protection is a film-forming sealer. In this case the sealer becomes a sacrificial coating, absorbing the brunt of the abuse and preventing staining. This is the most popular and preferred method of protecting any Terrazzo piece.

CAN I USE XS TERRAZZO IN A POUR-IN-PLACE PROJECT?

While it can be, there will likely be a large amount of grinding/polishing required to expose aggregate on the surface.

CAN I GRIND AND POLISH XS TERRAZZO?

Certainly! Just remember that if you still want to apply a sealer, we don't suggest going any further than 400 grit.

CAN I USE XS TERRAZZO OUTSIDE? WILL THE PIECES I MAKE FREEZE AND BREAK?

You most definitely CAN use XS Terrazzo pieces outdoors. There is no fear of the pieces becoming brittle and breaking, even in freezing temperatures, due to its extremely dense properties and its ability to flex during the normal thawing process.
