Place on a well levelled concrete slab.
Use normal cement adhesive.
Double bonding (on the floor and the back of the tile) to properly support the floor.
4 mm approx. adhesive.
Thin joint (1-2 mm), to be filled with grout.
The grout filler can be pigmented, provided that the floor is subsequently polished.

Very dirty floor ? - Single disc buffing machine and a fibre disc
For cleaning and stripping a very dirty floor before treating, use a heavy and large diameter polisher and hard fibre discs (black or brown) with water and PH neutral soap or mild ecologically sound cleaners, non-acidic. Buffing machines can be rented, stripping a terrazzo floor does not require the intervention of a specialist company. Rinse thoroughly to remove sludge generated by abrasion.
Vidéo 35 sec. Simple cleaning before treatment
Mop or brush the floor with water and PH neutral soap. Uneven floor ? - Abrasive polishing
Polishing with abrasives, like with marble, natural stone or terrazzo.
This polishing levels the floor, eliminating the little “ridges” between incorrect tile placements. There are various types of abrasives that give a similar result. This process needs to be done by a specialist company.

Treating, protecting, hardening
Floor for normal use: Sealer is necessary
The sealer is a product that penetrates into the pores in the surface of the tile. It is applied only once, after laying and once the floor is clean and dry. The sealer limits the penetration of water and grease, limiting stains.
Apply with a brush or a wool roller, very thinly, as the tile will saturate quickly.
Excess of sealer: eliminate/wipe with a cloth. An abundance of sealer will remain on the surface and as it dries it will create shiny residue.
Vidéo 51 sec. Heavy traffic granito floors: Crystalize
Crystallization is a physical/ chemical process that incorporates fluorosilicates (of sodium, magnesium, etc.) in the crystals of a “limestone” floor. Marbles, travertine, sedimentary rock or Terrazzo can all be crystalized after the initial polishing, or just to restore and regain the original look.
Crystallization hardens and waterproofs. A single disc machine, stainless steel wool or bronze wool disc, fluorosilicate based products and the expertise of specialised companies for the treatment of marble floor are needed to achieve this finish.

Maintenance of terrazzo tiles should be with PH-neutral soap, like all other limestone floors including traditional cement tiles, marble, natural stone or terrazzo.
Marseille soap in flake, green or black pasty soap, cleans whilst strengthening the terrazzo.
Always avoid acidic, alkaline cleaners and strong detergents, which will damage this type of tiles.
A deteriorated, stained or aged terrazzo will regain its original beauty by abrasive polishing or crystallization.
