Mosaic Floors - Terrazzo

Traditionally, terrazzo (a concrete-tile floor) consists of a mixture of stone (aggregate) and white cement, with the addition of a suitable pigment.

Mosaic Floors - Terrazzo

After mixing cement with water requires manual installation, or storage in a damp place in order to form the tiles. In this case, to open the unit you want to screed to level the area to turn in the terrazzo floor.

Manual installation of traditional cement-terrazzo requires a truly high skill, but in recent years preferred epoxy resin.

Cement-based terrazzo laid on the mixture with a high content of cement and are subject to cracking. Requires great skill handler to tsemetno-mosaic floors served for many years, whereas for laying terrazzo epoxy resin does not require such a high level of skill. Together with the advantages of modern resins, the price of installation and the required level of master down.

Today, terrazzo can be used in harsh chemical environment, with careful selection of the unit. Many acids, which could destroy the cement does not affect the modern resin.

About mosaic tiles

Although there are many kinds of terrazzo, the single most popular is tiled.

These floors are typically 28 mm thick and consist of two distinct sections, connected together. Basis of tiles consists of a conventional sand and cement, which is cheaper than terrazzo - a mix. Wearing more and more expensive mosaic is used only on the top of the tiles.

Tiles are laid in the mold and excess moisture squeezed out. As with all products made from cement, tiles should be gradual drying, so that they have acquired strength. Some manufacturers leave the tiles for a week in smoky rooms, which helps to manifest the best qualities of cement.

Laying tiles

Typically, tiles are placed in semi-arid sand and cement screed, and for those placed in the slurry, which attaches the tiles to level a timber. Rinse with water tiles at the end of each day shift removes sand and cement from joints and moisturizes the tie, giving it strength
Concrete slab on which are placed sand and cement screed should be wet before laying the screed.

Once the screed dries (typically 24 hours), on the surface of tiles applied to a mixture of colored cement and water and leveled on the surface of the tiles, filling all the seams and penetrating into the sand-cement screed, and thus zaravnivaya joints.

Cement grinding system

Despite the emergence of digital grinding machines that use diamonds to grind the first stage of grinding conducted a large grinding machine in three power levels. Dry sanding, less forgiving car, much faster and cleaner than wet. For the first phase requires 36 issue of grinding grain, the second and final - 80.

After the final stage of polishing a floor will be a little shine, which increases significantly after the application of penetrating primer that is partially absorbed into the surface of the tile, and finally otpolirovyvaetsya after drying.

Edge of the floor, inaccessible areas are polished by hand. Used wheels must be designed for specific grinding machines, to minimize the difference in the last two stages of grinding.

Dry sanding can be carried out with almost complete absence of dust due to special nozzles for hand grinders. You can now use diamond grinding to give a final shine a mosaic floor.

Polished Concrete

Since concrete consists of cement, sand and stone, it is also subject to grinding. Sanding removes the weak layer from the surface of the concrete and reduces dusting.

After the formation of the concrete base and the top grinding his ground and polished to give a final shine. This is the most economical way of building a mosaic floor.

Sanding epoxy-mosaic floor

High speed coarse diamond grinding is used to remove 1 or 2 mm of epoxy resin covering the unit. Diamond grains should be used until such time until you remove all the rough edges. With this type of grinding, of course, to show all the scars and scratches, which can then be removed followed by grinding.

Most epoxy terrazzo requires pouring a solution to fill the shells in the concrete.

After 24 hours excess mortar removed a light sanding. After this stage, you can use the primer.
