Marble is a high-end material, and its natural texture is highly decorative, ornamental and transparent. Whether it is construction in the early stage or maintenance in the later stage, it needs careful care. Many people spit out that it is expensive, troublesome to maintain, and very delicate! But its lady's face is really worth throwing money at, noble and beautiful, and other simulated tiles are far behind.

1. Techniques and precautions for paving marble floor

11 Construction preparation

Preparation materials: prepare marble blocks, cement, medium sand or coarse sand, stone surface protective agent and other materials in advance to meet the requirements of design and construction specifications.

12 working conditions

after indoor plastering, water and electricity equipment pipelines and other operations have been completed, it is the construction process of paving marble. After the marble plate comes into play, it should be stacked indoors on its side, and the wood should be padded under it. And check in detail whether the variety, specification, quantity, etc. meet the design requirements. If cracks are found, they shall not be used.

check the floor for hollowing, delamination, cracks, etc., and repair them, and check the squareness of the room.

13 be familiar with the drawings and try to spell

check the details of the ground construction to understand the dimensions and practices. Before the formal laying, arrange and try to spell the marble in each room, and arrange the patterns and colors of marble plates according to the requirements of drawings, so as to check the gaps between plates and avoid making mistakes in patterns and colors, and pay attention to checking the relative positions of plates and walls, columns, holes, etc.

14 paving cement

according to the horizontal line, determine the thickness of the ground leveling layer and pull the crosshairs.

cement mortar for leveling layer is laid. Generally, 1:3 hard cement mortar is used for leveling layer, and the degree of hard cement mortar should be kneaded by hand and not loosened. Pay attention to laying mortar thickness not less than 31mm, otherwise it is easy to empty drum.

note: the ratio of cement mortar is 1:3. If the ratio is unreasonable, delamination, peeling and sanding will occur.

15 Paving marble blocks

Generally, the room should be paved from the inside out, that is, starting from the side far away from the door, paving in turn according to the trial number of marble, and gradually retreating to the door. When placing, pay attention to the falling of the four corners at the same time. Tap the wooden pad with a rubber hammer or a wooden hammer (the wooden hammer shall not be used to directly hit the marble slab), level it with a spirit level according to the horizontal line, and pave the first piece to both sides and in the backward direction in sequence.

16 Acceptance

After the paving is completed, check whether it is empty with a wooden hammer after 24 hours, and check the flatness with a guide rule or a level. Steel wire balls and hydrochloric acid cannot be used for subsequent surface cleaning. Then it is forbidden to work on the surface for one week, and it is forbidden to walk for three days. After the completion of construction, the finished surface should be protected with carpets, plastics and other items in time to prevent pollution and damage.

Second, the later maintenance

Marble is very delicate as a floor decoration, and it needs to be waxed and polished regularly to maintain its beauty. Especially in the rainy and hot weather in summer, it is simply the peak period of marble returning to alkali.

if water and water marks appear on the marble, it will enter under the foundation, be absorbed and continuously added to the cement mortar at the grass-roots level to form calcium hydroxide solution, which will be transported to the ground to cause alkali return, resulting in white atomization, cracking and even holes on the marble floor.

There are various reasons why marble returns to alkali, so we should pay attention to protect it at ordinary times!

1. Clean, wipe and wash with little or no water as far as possible, and try to avoid all kinds of oil spills and infiltration. If possible, marble can be treated in advance for oil prevention.

2. Avoid dragging hard objects or sharp objects on the marble floor. When using the cart, put soft cotton cloth and paper shells under it.

3. Pay attention to the indoor ventilation and dryness. Long-term coverage and closed environment will lead to the inability of water vapor to volatilize and accelerate the degree of alkali return of marble.

4. polish and wax the ground marble regularly.
