If they want to make the imitation marble paper in their home last longer, they can't be careless or anxious when it comes to paving. ​1. It is a very important part of the construction not to paste imitation marble paper on rainy days and the weather is cloudy and wet. Professional construction masters told us that the most fearful thing about pasting wallpapers is rushing to paste them. 'The difference between the imitation marble paper and other wall materials is that when the imitation marble paper is attached, the moisture-proof treatment of the wall should be done well.' The master said, first of all, the base film should be used to professionally treat the wall. If the work is blindly rushed to finish the project ahead of schedule, the base of the wall does not meet the construction requirements, 'especially if it is not dry, the imitation marble paper is prone to cracking, mildew, bulging and other problems in the future.' 'The owner must wait until the base of the wall is completely dry. Imitation marble paper is laid after it is transparent. It should also be optimistic during the laying process, and don’t be quick. Generally speaking, it takes at least one morning to lay imitation marble paper on a wall of about 45 square meters.” people said. It is worth mentioning that if the weather is rainy or the air humidity is too high, it is necessary to stop the work reasonably.

The quality of the basic treatment not only determines whether the construction personnel can install the imitation marble paper smoothly, but also determines the installation quality and the service life of the imitation marble paper. This work is very necessary. Although it is sometimes time-consuming and tiring, if the basic treatment is ignored and construction defects are caused, the gain is often more than the gain. So, for different grassroots, what kind of treatment method should be taken? ​Treatment of the surface of the wood base: (1) The moisture content of the wood base should be no more than 12%. (2) The surface should be flat and free of dust, oil and other dirt. (3) Brush it with paint thinly to prevent the wood fiber from swelling with water. (4) There are nail caps on the wooden surface, sink the nail caps into the wooden surface, and apply anti-rust paint. (5) Use putty to fill up the joints, and after drying, mix the putty with latex and water, and scrape it 1-2 times. (6) Smooth with sandpaper and brush the base film on the surface. Note: If the surface is smooth, flat and absorbent wood surface, the imitation marble paper can be pasted after a thin brush of varnish on the surface. ​Treatment of gypsum board surface: (1) Use anti-rust paint to dot the screw caps to prevent rusting. (2) Use water with white latex to adjust the gypsum to fill the joints and nail holes. (3) After drying, apply a bandage to the seam. (4) Scrape the putty 2-3 times. After drying, polish it to be smooth and smooth, and the yin and yang angles are straight. (5) Brush the base film once. Treatment of the old wall: (1) The pulverized old wall cannot be directly pasted with imitation marble paper on the surface. (2) Sprinkle water on the surface, and then use a spatula to shovel off the coating layer and the powdered layer. (3) After shoveling, brush the interface agent or varnish again. (4) Use gypsum or putty to level the wall (if there is a large crack on the wall, stick a layer of cloth before scraping the putty). (5) Brush the base film once after polishing and smoothing. Note: For walls that cannot be shoveled, you can use a wallpaper knife to cut small squares like spider webs on the wall. The deeper the scratches, the better, and the smaller the squares, the better. ​Treatment of the hair embryo room: (1) The newly built hair embryo room is usually scraped with waterproof putty, and the basic structure is relatively strong, so there is no need to remove it. Just straighten the yin and yang angles, polish and brush the base film once. (2) Some rough embryo houses in southern regions are scraped with white cement. This base layer cannot be directly pasted with velvet fiber wallpaper and metal wallpaper, and can only be pasted after the putty is scraped. Treatment of concrete and plastering surface: (1) The moisture content of the base layer of the wall should not exceed 8%. (2) The base layer is firm, and there should be no problems of efflorescence, hollowness and looseness. The efflorescence part is neutralized with a 9% dilute acetic acid aqueous solution, and then rinsed with clean water. (3) The holes and cracks are smoothed with plaster (if the cracks are too large, a white cloth must be applied first). (4) Scrape the putty 2-3 times and polish it smooth after drying. (5) Brush the base film once.​
