How to Install PVC sheet flooring
One, Ground detection
1,Use temperature and hygrometer to detect temperature and humidity, indoor temperature and surface temperature is better 15 degrees centigrade, should not be under 5 or higher than 30 degrees centigrade. The humidity of the construction should be bounded between 20%-75%.
2,The moisture content of the base is detected by the water content tester, and the water content in the base should be less than 3%.
3,the strength of the base should not be lower than the requirement of the concrete strength C-20, otherwise should adopte self-leveling to strengthen the strength.
4,The surface hardness of the base is not less than 1.2 MPa.
5,For the construction of PVC Sheet flooring, the roughness of the base should be within the range of 2 meters, the difference between high and low is less than 2 mm, otherwise, otherwise, change change to the proper self leveling.
Two, floor pretreatment
1,Grinding the floor by grinding machine with more than 1000 Watt, remove paint, glue and other residues, bulge and loose plots, empty plots.
2,Use an industrial vacuum cleaner with no less than 2000 Watts to clean the ground.
3.For cracks on the floor, stainless steel reinforcement and polyurethane waterproof adhesive can be used to repair the surface of quartz sand.
Three,self leveling construction - bottoming
1,The absorbable base, such as concrete and cement mortar leveling layer, should be treated with a multipurpose interface treatment agent to be diluted by 1:1 ratio to water.
2,The non absorbable base, such as tiles, terrazzo, marble, etc., suggest using dense interface treatment agent to carry out the bottoming.
3,If the base water content is too high (>3%), and need immediate construction, the epoxy interface treatment agent can be used for bottoming treatment, but the moisture content of the base should not exceed 8%.
4,The construction of the interface treatment agent should be uniform, without obvious liquid accumulation. After the surface drying of the interface treatment agent, the next step of self leveling construction can be carried out.
Four, self leveling construction - mixing
1,A package of self leveling is poured into a mixing bucket with clear water in accordance with the specified water cement ratio, then dumpe and stirre together.
2,In order to ensure the uniform mixing of self leveling, the electric drill with high power and low speed must be used to mix with a special agitator.
3,Stir to the non - lump uniform slurry, the static and mature for about 3 minutes, and then briefly stirring once.
4,the amount of water added should be strictly in accordance with the water cement ratio (please refer to the corresponding self leveling manual). Too little water can affect liquidity. Too much will reduce the strength after curing.
Five,self leveling construction - laying
1,The well mixing self leveling slurry dumped in the floor construction, it will automatically flow and level the ground, if the design thickness is less than or equal to 1mm, it needs a special tooth scraper scraping.
2,The construction personnel wear special spikes, entering the construction ground, gently roll the self leveling with the self leveling roller for deflation, release the the mixed air to avoid bubble pits and interface height.
3,After the completion of the construction, please close the scene immediately, no walking within 5 hours, 10 hours to avoid the impact of heavy objects, 24 hours after the laying of PVC floor.
4,In winter construction, the floor should be laid for 48 hours after the construction of self leveling.
5,If the self leveling is required to be polished and polished, it should be carried out after 12 hours of self leveling construction.
Six,floor paving, pre-laying and cutting
1,The floor should be placed at the site for more than 24 hours to restore the material, and the temperature is in accordance with the construction site.
2,When laying, two pieces of material should be clung to and no seams.
Seven, floor paving - paste
1,Choose appropriate glue and scraping board suitable for PVC sheet flooring.
2,Block paving, please send the bulk from the middle to both sides turn up, also will be back after cleaning on the ground and floor glue.
4,Different paste in the construction requirements will be different, specifically refer to the corresponding product instructions for construction.
Eight,The cleaning and maintenance of the floor
1,PVC series floor for indoor development and design, should not be used in outdoor sites.
2,Please select the appropriate cleaning agent for regular cleaning and maintenance according to the method recommended by the factory.
3,We should avoid high concentration solvents such as toluene, banana water and strong acid and strong alkali solution on the floor surface. We should avoid using improper tools and sharp tools to scrape or damage the floor surface.
Nine, Related tools
1,Ground treatment: surface moisture tester, surface hardness tester, floor grinding machine, high power industrial vacuum cleaners, wool roller, self leveling mixer, 30 liter self leveling mixing barrel, self leveling scraper, spike tooth.
2,Laying on the floor: the floor
trimming device, a cutting knife, two meters of steel ruler, glue scraper, steel roller, July type cutting knife.
