Specification of Marble Stone

Marbles are metamorphic rocks. This type of rocks is suitable for polishing to enhance its shine. Marble stone is hard, sound, dense and homogeneous in texture with crystalline texture. It is uniform in color, free from stains, cracks, decay and weathering. The stones come in several colors. Marble stones are available at various quarry/rocks and are known by the name of quarry/rock such as Makrana Marble, Dungri Marble, Rajnager Marble, Abu white marble etc.

Specification of Marble Stone Flooring

Marble stone flooring consists of 20 mm to 25 mm thick marble slabs laid over 20 mm thick base of  cement coarse sand mortar of 1:3  and jointed with white cement slurry mixed with pigment to match the shade of stone.  The marble stones/slabs used in flooring or dado are cut according to the size and shapes given in drawing or to suit site dimension of the room and desired pattern. All angles and edges of marble slabs are true and square and are free from chipping. The surface is true and plain.

Installation of Marble Stone Flooring

• Preparation of sub base: Base coat consisting of cement concrete 1:8:16, 1:5:10 or 1:4:8 should be laid on compacted earth under marble stone flooring. 

• Laying out of marble stone slabs     

• The base concrete or RCC slab on which marble stone slabs are laid should be thoroughly cleaned.

• The average thickness of bedding mortar under  marble stone slab should be  20 mm thick and the ratio of  cement mortar should be 1:3

• The sand used in mortar should be coarse sand. 

• The thickness of bedding should not be less than 12 mm in any place

• The top surface of mortar (bedding) should be leveled correctly by adding fresh mortar at hollows if any.

• The mortar is allowed to harden and cement slurry shall be spread at the rate of 4.4 kg per sq. meter.

• Marble stone slab to be paved should then be lowered gently back in position and tapped with wooded mallet till it is properly bedded and leveled with adjoining slab.

• Care should be taken to match the grains of slabs.  

• All stone slabs should be laid in same manner.

• After lying of each slab surplus cement on the surface of slabs should be cleaned.

• The surface of flooring as laid should be true to slopes. 

• The edges of slabs already paved are  filled with white cement with or without admixture to match the shade of the stone slabs




Curing Of Marble Stone Flooring

The Marble stone floor should be cured for a minimum period of seven days.







Polishing and Finishing




• The grinding may be done either by hand or by machine.

•  Manual grinding should be done after two days  of laying of marble flooring

• Machine grinding should commence 3-4 days after laying marble  stone flooring




First Grinding




• The grinding should be done by machine with grit No. 60.

• The water should be used profusely during grinding.

• After grinding the surface should thoroughly be washed to remove all grinding mud.

• A grout of cement and pigment in the same mix and proportion apply to the surface.

• It should be allowed to dry and then cured for four days.




Second Grinding




The second grinding is done with machine fitted with fine grit blocks No120. The surface is again washed cleanly and is repaired if required.

Final Grinding




• The final grinding with machine fitted with finest grade grit blocks No. 320 should be carried out the day after second grinding.

•  The grinding should be done to get the surface even, smooth without any pinholes. 

•  Care should be taken during final grinding that foreign matter, particles of sand etc. do not scratch the surface.

• After final grinding, whether by machine or by hand, the surface should be washed clean.  

• Oxalic acid powder should be dusted over the surface at the rate of 33 gm per square meter.

• The water is then sprinkled and the surface is rubbed hard with felt or pad of woolen rags.

•  Next day the floor should be wiped with a moist rag and be dried with a soft cloth and be finished cleanly. 

• The floor should then be covered with oil free saw dust which is removed after completion of all construction work, such as painting, distempering, electrical work, plumbing, joinery work etc.  

• After occupying area the floor should be washed cleanly with dilute oxalic acid solution, be dried and rubbed with clean cotton waste.

• In case wax polished surface is desired, wax polish is applied sparingly with soft cloth on clean and dry surface.

• The surface should be rubbed thoroughly with clean cotton waste or a polishing machine fitted with felt or jute bag bobs.

• Any surplus wax should be mopped up and rubbing is continued until the floor ceases to be sticky.




Granite Polishing:




• The grit block used in granite polishing has designation number 1 to 6.

• The initial cutting and grinding of joints to a smooth and level surface is done with machine fitted with grit block number 1 and 2.

• The subsequent grinding with final and final grit block number 3 to 6 is for polishing and achieving a fine sheen on the marble. 

•  This is followed by buffing with tin oxide powder. Wax polishing is not necessary in granite polishing.

Precautions




•  You can start laying stone slab after the bedding has sufficiently been leveled and lightly compacted.  

•  Care should be taken that the floor is not left slippery.

• Neat cement should be applied on joints.

• Make sure that each stone slab is laid perfectly in level and is tapped with wooden mallet till it is aligned with neighboring stone slab.

• The joints should be in straight lines and not more than 1 mm wide.

• Fill in the joints with cement-pigment paste of matching color after one day.

• Minimum seven days curing is recommended after stone slabs are fixed as inadequate curing leads to stone slab de-bonding from mortar.



This is the final result.
