Terrazzo is really a cement based finish employing granules or marble chippings. It really is employed on wet rooms or high targeted traffic regions. It consists of colored chippings. This is laid on wood floated surfaces. Colored cements are also be utilised to give the desired finish or texture. The cement based finish is ground with a machine to give a smooth surface. Strip are utilized to divide the surfaces into bays. The bays can be patterned for the different shapes and sizes.
When laying terrazzo, the floor concrete is initial ready to receive it. The concrete is hacked and a floor screed laid. Once the floor screed is dry, upvc or aluminum strips with all the desired color are laid. The floor screed is wood floated to give sufficient bonding using the chippings. The strips are bedded onto the screed using cement grouting. The thickness of the chippings finish is about ten millimeters from the cement screed level.
Once the strips which might be embedded into the screed are set, the laying of terrazzo finish commences. The marble chips are very first mixed without having the bonding cement. If it can be black and white chips to become used, the mix is fifty % back and white respectively. The pozzolana cement is then added for the mix. After this water is added to produce a superb consistence. It really is spread into the bays employing a steel trowel. This trowelled level with the strips.
The terrazzo marble chips are sufficiently steel trowelled till a perfect level surface is accomplished. The mixture of cement and marble is left to harden for seven days. A grounding machine is then used with water to smoothen and grind the formed surface. This is grinded till it's even and smooth. Filling of the pores if any is carried out using a cement slurry then it's grinded once again. The surface is cleaned with water making use of a soft brush and allowed to dry.
