Pvc flooring laying requires a higher foundation for the floor. Before the construction, the ground floor inspection standard shall be strictly checked with reference to the “Floor Foundation Testing Standardâ€. The ground floor shall be proposed to the unqualified floor foundation and a 2mm self-leveling cement shall be laid. The grinding treatment may be used for construction. The following Chuanxi floor introduces you to the details:
Basic points
Regardless of any kind of base material used as the base layer of pvc flooring, if the leveling layer is damaged or the flatness exceeds 5mm, the grassroots construction contractor shall be responsible for the quality responsibility.
Second laying pvc flooring grass-roots requirements
The conditions of the base layer not only have an important influence on the appearance of the installation but also relate to the life and durability of the floor. Therefore, the base should be kept dry, strong, rigid, smooth, flat, clean and free of dust and grease.
1. Concrete base layer: The new cast and cast-in-place concrete base should meet the standards for installing pvc flooring. The design of the base should meet the design strength requirements for the static load and dynamic load of the building. The concrete base must be sturdy and completely dry, and the surface should be smooth, dense, flat, free from irregularities, cracks, and trace defects.
If there is a damp foundation beneath the concrete base, the floor must be provided with a moisture barrier to prevent moisture infiltration. Moisture-reducing additives and curing agents cannot replace moisture barriers. Every 25 mm thick fresh concrete base should have a drying period of at least one month. As far as possible before the installation of moisture testing.
Pvc Flooring Laying the base layer ensures that there are no curing agents on the surface, oils, greases, paints, dust, and any other debris that might block the adhesive from adhering, cracks, honeycombs, or bulges. If the surface does not meet the requirements, the cement mortar leveling layer should be used for repair or self-leveling cement leveling.
If curing agents, hardeners, sealers, or mold release agents have been applied to the surface of the concrete, these materials should be completely removed by sanding, sandblasting, or grinding before laying the floor, because they weaken the adhesion of the adhesive.
2. Wood base: All wood bases must be installed with a convection ventilation layer of at least 450 mm to prevent distortion of the floor and excessive deformation of the base. The newly installed wooden base should be sturdy and composed of dried wood without excessive squeezing or warping.
All loose boards of the original wooden base should be re-clamped and the heavily worn or damaged boards must be replaced. If necessary, the floor can be polished so that it does not undulate. Or use a composite splint or an approved fiber cement concrete floor leveling layer to cover the base layer. The leveling material must be 75 mm around the edges of the board, 10 mm margins, and 100 mm to 150 mm depth through the board.
3. Old pvc floor and rubber floor base: It is recommended to remove the existing pvc floor and rubber floor. If this cannot be done, implement appropriate and sufficient measures to ensure that the old floor can meet the standards for installing new flooring.
The existing pvc floor and rubber floor must be smooth (no deformation or bulging, will not affect the post-installation effect), integrity, firm bonding and proper installation on the recommended substrate. The existing pvc floor and rubber floor surface can not have any signs of adhesion, moisture, alkali salt or hydrostatic pressure, completely remove the wax water and other coatings on existing materials, and dents and damaged areas should be replaced or repaired. Installation on existing pvc flooring and rubber flooring will reduce the surface pressure resistance.
Note: Existing pvc floors and rubber floors may contain asbestos that are not easily identified. The specification may require that the material be tested for asbestos content. The installer should ensure that the method of operation is safe, does not pose a health risk, and meets all legal requirements.
When installing on existing pvc flooring and rubber flooring, flooring adhesives may require more open time to avoid blistering.
4. Expansion joints: It is recommended that pvc floors do not cover expansion joints. Expansion joints should be added pvc floor expansion joint cover strip.
Three laying pvc flooring working conditions
During the early, middle, and late stages of installation, the temperature in the area where the flooring is installed should be maintained at a minimum of 18°C ​​for 48 hours. Please note that the low temperature base has a considerable effect on the open time of the adhesive.
Four laying pvc flooring floor treatment requirements
Basic requirements: The base layer of pvc flooring should be smooth, dry, strong, free of dust and dirt. The construction steps mainly focus on five words:
One "flat", two "grind", three "dry", four "sweep", five "suck."
"Flat" refers to the leveling of the original paint on the ground, cement, etc.
"Grinding" refers to using a grinding machine to grind the undulating ground into a continuous two square meters with a surface thickness difference of no more than 2.0 mm.
"Dry" means that the flattened ground is naturally air dried or quickly dried by heating so that the entire ground water content does not exceed 6%.
"Sweeping" means sweeping a broom or dust to clean the ground and all corners.
“Sucking†refers to using a large vacuum cleaner to completely inhale the ground of the construction ground and the cutting material several times, and it is necessary to remove tiny particles on the ground. At this time, clean shoes should be used to operate.
Five laying pvc flooring construction preparation
1. Before laying the floor, pvc floors should be laid out for at least 24 hours in a construction site with an ambient temperature of 18°C ​​or more to remove the stress in the materials.
2. The first thing to do is to prepare the construction tools: Check the operation and power usage of the main machinery and equipment, and arrange the construction power supply and water source. Import tools should not be mixed with other power tools using a wiring board, and must be equipped with regulators and power protection devices. Avoid excessive current caused the machine can not function properly, delay the duration. Check the use of various types of hand tools, such as: the use of tools such as ground cutting knife, slotted knife, joint cutter, scraper, etc., and whether the surface of the pressing roller is clean and smooth, if it fails to meet the standard emergency Replace its wear parts to ensure construction quality.
3. Brush the interface agent; After the self-leveling is completed, there may be tiny particles and floating dust on the surface. In these cases, it is necessary to use a grinding machine for further fine leveling treatment. After grinding, the residual dust on the ground will be difficult to remove. The need to re-apply water-based interface agent, the purpose is to close the small pores and dust on the self-leveling surface, make the surface smooth and improve the adhesive effect of the adhesive, to avoid the floor after the completion of the drum and degumming.
4. Check the construction environment: Before laying the floor, check the temperature at the construction site. The temperature in the construction room should not be less than 18°C. The relative humidity of the air should not exceed 75%. Keep adequate ventilation in the work area and do not cause contaminants to enter other parts of the building.
5. Placement material: Before construction, pvc coil floor must be laid flat on the flat ground. After it is restored to flat and loses material stress, it is placed in the room to be coated with adhesive. Reasonably arrange the cutting area to ensure that the cutting area is free of dust and sand. Transport transporting coils are used for special transportation tools. Damaged floors generated during transport handling should be cut off with plastic trimmers before being opened.
Six laying pvc flooring measurement and tailoring
Basic requirements: Measure the dimensional error by combining the two aspects of the laying design plan through field measurement, determine the defense point according to the laying design plan, and use the ink box to pop out the floor laying profile. Cut the material according to the contour line, properly arrange the layout of the welding line and parquet, and minimize the material loss.
Operation points:
The cutting material must be specially responsible;
If there are directional patterns on the floor, we must always pay attention to the consistency of its direction;
Every time you cut, you must obtain accurate data from the field;
Each time the material is opened, care must be taken to keep a 2-3 cm margin between the material and the material.
Seven pvc floor laying and joint processing
Basic practices and requirements: The pvc flooring is bonded evenly and firmly to the floor with an adhesive, and the lap joints are treated as splicing with slight gaps. The gap should be within 0.2-0.5mm.
Construction points:
Use glue scraper to glue the glue evenly to the ground according to the glue construction specification and dosage.
Adhesive types and application:
1, Dispersion-type floor adhesive is a kind of single-component adhesive, suitable for pasting all kinds of pvc flooring materials and coils, pvc backing carpets and vinyl asbestos board and CV membranes and non-absorbent ground. Air drying time: about 10-20 minutes, can be attached to the floor time: about 30-40 minutes.
2, Super Floor Adhesive is a high-grade strong dispersive adhesive, which is used for bonding pvc flooring materials on the ground, walls and stairs, 2.5mm thick rubber coils and blocks, and pvc composite flooring. Super floor adhesives are suitable for all types of absorbent and non-absorbent ground substrates. Drying time: wet adhesion method: Absorptive substrate, 10-20 minutes. Pressure-sensitive dry-bonding method: Non-absorbent ground substrate, 30-60 minutes. Can be posted floor time: wet adhesion method: absorbent base, 60 minutes. Pressure-sensitive dry-bonding method: Non-absorbent ground substrate, about 120 minutes.
3, Conductive floor adhesive is a strong dispersion adhesive with conductive formula, used for wall / floor, stairs, all kinds of conductive or static dissipative pvc floor rolls and blocks, and 3.5 Rubber film within millimeter thickness and rubber material within 2.5 mm thickness. Drying time: wet adhesion method: Absorbent substrate, 10-20 minutes. Pressure-sensitive dry-bonding method: Non-absorbent ground substrate, 30-60 minutes. Can be posted floor time: wet adhesion method: absorbent base, 60 minutes. Pressure-sensitive dry-bonding method: Non-absorbent ground substrate, about 120 minutes.
4, flax flooring adhesive is a strong dispersion adhesive, with a rapid and strong initial viscosity and cohesion, especially for the paste of linen and cork flooring. And it is suitable for inorganic absorbent ground base. Drying time: 0-5 minutes. Floor time available: Approx. 15-20 minutes 5. Polyurethane Floor Adhesive is a solvent-free reactive two-component polyurethane adhesive suitable for bonding PVC, rubber, linen flooring, ceramic tile, stone, foamed polystyrene. Ethylene, wood board, gypsum board, cement board, artificial turf and other materials. As well as for all types of absorbent and non-absorbent ground substrates. Airing time: no need. Posting time: about 40-50 minutes.
6, Polyurethane conductive floor adhesive is a non-solvent reactive two-component polyurethane conductive floor adhesive, can be used for absorbent and non-absorbent commercial and industrial ground and other heavy load base static conductive PVC and rubber Laying of the floor. Airing time: no need. Posting time: about 40-50 minutes.
Pvc flooring laying method:
First lay the floor of the coiled material flat on the ground. When the distance exceeds 8 meters, the floor shall be divided into two sections. Then roll up one side of the floor and spread the glue on the rolled floor. Wait until the solvent contained in the glue applied to the floor volatilizes. Then create a viscosity. Then paste it and push it in the same direction by hand. Pressure must not allow air to remain on the floor in glue. The glue volatilization time changes according to the construction temperature change. For example, at room temperature 20 degrees Celsius, the glue volatilization time is 30 minutes, the glue changes from milky white to anti-transparent, and the hand-squeegee does not produce strong stickiness. Then it can be pasted. . Pasting at the right time can ensure that the floor does not have bubbles or drums. The same method is used to paste the other half so that the floor and the ground can be sufficiently compacted with the rollers, so that the glue can be bonded tightly to the floor and the two rollers can be rolled in sequence with the glue roller. If bubbles need to be squeezed out with a cork or hand, welds are welded with a welding torch 24 hours after cleaning the floor.
