Stone laying should be stone base treatment.Paving stone ground base must be cement mortar or concrete of the rigid ground.Before paving the road, the dirt on the ground should be cleaned first.To smooth ground should chisel hair treatment, or the cement mortar of 20% 107 glue is flung on the ground the bond layer of form hair.The stone material that shop installs should spell in advance, pair of line, pair of grain make number.The back of the sheet shall be clean and free from dirt.After cleaning, it should be immersed in water.After dampness, put it in the shade.Apply protectant on back and sides.
Before laying, the control line should eject from the ground.Find the center point according to the length and width of the room.Two vertical positioning lines pop up with the center point as the core, and then the positioning line bounces to both sides according to the stone specifications.Two standard plates are laid on the diagonal of the positioning line as control panels for elevation.
The seam of elastic wire should be controlled at about 1mm, and the elevation should be controlled according to the cable when laid.The stone material board spreads the responsibility to should be made by the dry hard mortar, the market now has already made up good sell.Can also be held in the present humidity to hand into a group, ground field configuration.Mortar shall be mixed according to the volume ratio of cement :sand= 1:3.When shop is installed, brush a cement mud in the ground first, use dry hard mortar to go up again next, width should be bigger than stone material 20 millimeter, and thickness should be taller than mark 40 millimeter.The mortar is smoothed with an iron trowel.The stone to the good horizontal and horizontal lines after the spread, with rubber hammer or wooden hammer gently from the center to the four edge of the stone surface, in order to shake the mortar.
After laying the stones, the level should be corrected with a level gauge immediately.When there is any gap or unevenness, lift the stone and smooth the mortar again.Mortar should not be filled at the bottom until the stone surface matches the elevation line.After the stone surface is aligned with the elevation line, the stone is lifted, the mortar surface is poured with 5mm cement slurry, and then the stone is laid formally, with the leather hammer hard hit solid, and level with the level.Paving roads should be laid one by one and then paved in sequence on either side or along the road.
Stone paving completed, should be watered 2~3 days.Maintenance methods are generally used to water the method of conservation, so that the stone surface in a wet state, plate and the ground firmly bonded.After curing, the ground should be polished as a whole, and then grouting with thin cement mortar.After filling, should clean the cement slurry on the surface in time to prevent the contamination of the stone surface layer.Finally, clean and wax the floor thoroughly.
