How To Refinish Terrazzo

Refinishing terrazzo surfaces offers numerous benefits, including scratch and stain removal, increased durability with protective sealers, and a cost-effective alternative to replacement.

Steps To Refinish Terrazzo

Step 1

Initial Cut & Clean

Remove sealers, waxes  and contamination using WerkMaster 100 Grit Terrazzo Tooling. This process is carried out dry but for heavy removal, a light water mist can be used. This stage also requires densification using WerkMaster ULTRAhard Terrazzo Densifier.

Step 2

Hone & Polish

Use our 200 Grit Terrazzo Tooling to quickly and easily hone and start your initial polish.

Step 3

Transitional Stage - Removing Metal Tooling Marks

Use our 400 Grit Terrazzo Tooling to give your terrazzo flooring a long-lasting shine.

Step 4

Densify and Harden the Concrete

Low maintenance and long lasting beautiful floors that are acid and stain resistant. ULTRAguard sealers ensure a minimum 24-hour stain and etching resistance to acids, wine, coffee, vinegar, mustard and other chemicals, making them an excellent choice for grocery stores, food courts, garages, restaurants, hospitals, schools, hotels, etc.



Designed to be applied to surfaces to make them harder, stronger, less permeable, more durable and water resistant.

Care & Maintenance Of Terrazzo

When dealing with terrazzo, the use of a pure surface coating (as most floor waxes are) is unnecessary and ordinarily NOT recommended. The terrazzo surface is at least 70% marble or aggregate. Applying a surface coating or wax may decrease the non-slip co-efficient of friction below the standard rating of 0.5.

The marble chips and aggregates (which make up 70% of the terrazzo floor) have very low porosity and do not absorb most staining substances. The portion of the terrazzo that needs protection is the binder, especially Portland Cement, which is porous and will absorb stains. Terrazzo does not need protection from wear, it needs protection from absorption and this is achieved through the use of a penetrating sealer which seals off the pores in the binder.

The WerkMaster Terrazzo System

What are the advantages of a WerkMaster over today’s planetary and direct drive machines? If your customers are tired of looking at an undulating floor that gives off uneven light reflection and is harder to maintain, you can now offer them a brilliant completely flat floor.

You can expect a minimum performance benefit of 2 to 1 over traditional equipment with WerkMaster machines – grinder, stripper, sanding, burnisher, buffer, polisher and edger. WerkMaster machines get up to 1/8″ of the wall, so you have perfectly polished floors from edge to edge.

Never Wax Again

Want to save even more money for your customer? Protect their floors with ULTRAGuard and they will never wax again. Easy to maintain, giving them lower maintenance costs, a slip factor rating of 7 on the James scale, and resistance to acid, vinegar, pop, and all other common acidic and staining products for a minimum of 24 hours without etching.

A much-respected member of the terrazzo industry stated…

“WerkMaster is revolutionizing the terrazzo industry, and I want to be part of that leading wave of technical advancement in terrazzo polishing.”

Whether it is epoxy, poly aspartic, cementitious terrazzo, WerkMaster delivers uncompromising results better and faster than any competitor’s technology.
