Paste the wallpaper dry or wet paste

Sticking wallpaper dry or wet is related to the material of the wallpaper, paper-based wallpaper should generally be dry paste, PVC-based wallpaper can be wet or dry. Wallpaper wet stickers are easy to pull out the seams (the seams are pulled apart after drying), but easy to stick flat clothes. Dry stickers are not easy to pull out seams, but they have high requirements for the craftsmanship of wallpaper.

1) Base treatment: use putty to level the wall. Special attention should be paid to the yin and yang angles of the wall are straight and square, and there can be no falling corners, and the wall surface should be guaranteed to be smooth and there can be no protruding pitting, so as to achieve a solid and firm base without looseness, peeling, and powder loss.

At the same time, the moisture content of the base layer should not be greater than 8%, and the surface should be brushed with sandpaper.

2) Baseline elastic line: each wall is required to be elastic line, pop up the center line on the wall with a window and pop up the vertical line at nearly 5cm on the window sill to ensure the symmetry of the wallpaper between the windows, and elastic the line to the edge of the mouth of the baseboard; When there is no hanging mirror line, the horizontal line should pop up.

3) Paper-cutting: planning and numbering the wallpaper before paper-cutting; Assign a special person to be responsible for cutting paper, and set up a special shelf to place wallpaper; According to the height of the wallpaper paste, a margin of 10mm 30mm is reserved; The edges of the wallpaper should be neat, without burrs, and stored flat.

4) Sealing primer: use a special primer to seal the brush.

5) Glue: The back of the wallpaper and the wall should be coated with adhesive, and special adhesives should be used; The adhesive is prepared on site, filtered through a 400-hole cm3 sieve, and the prepared glue should be used up on the same day. 6) Pasteing:

Principle: It is the vertical plane first and then the horizontal plane, the details first and then the large surface; When pasting the vertical surface, it will go up and then down, and when it will be pasted on the horizontal plane, it will be high and then low; Start with the vertical line that springs off the wall and close at the dark corner. The order is to choose the backlight near the corner of the window sill and paste it in turn.

The chaotic wallpaper is pasted by lap method, and the pattern and pattern wallpaper are spliced together. Ensure that there is no seam in the direct sight of the meter. There is a color difference in the wallpaper after the pre-selection adjustment construction.

7) Finish cleaning: the glue and stains on the surface should be wiped clean in time, and all kinds of warping angles and edges should be repaired, and compacted with wooden sticks or rubber rollers. If there are wrinkles on the surface, you can gently wipe the paper surface with a wet towel when the glue is not dry, so that it is wet, and the wallpaper is gently scraped after stretching, and the rolling is flattened.

Do you have to roll glue on the back of the wallpaper?

Dry paste, slippery orange on the wall with glue.

Materials: appropriate amount of wallpaper, a ruler, a marker, a knife, collapsing glue, a clean rag, a scraper.

Operation steps: 1. Wipe the dust off the wall with a dry rag.

2. Measure the specific size of the wall.

3. Cut the wallpaper according to the size of the wall, pay attention to have a surplus of 2-3 cm.

4. The measured wallpaper is cut neatly.

5. After applying a layer of glue to the cover, fix the wallpaper on one side (and finally the bottom).

6. Then use a scraper to slowly scrape the distance between the wallpaper and the glue upwards.

7. After pasting the first piece, the second piece of wallpaper should overlap with the first piece of the letter group, and still scrape the wallpaper with a scraper in one direction.

8. After all the pasting, use a knife to cut off the excess wallpaper.

9. In this way, the whole wall is fitted.

Dry stickers are glue on the wallpaper! Wet paste is the wall glue!

dry paste; Cut the wallpaper to about the same height as the wall, and then glue the wallpaper!

Wet paste: First of all, take the wallpaper apart and wet wipe it with water! The purpose is to make the wallpaper swell! Then glue the walls!

Comparison of advantages. Dry stickers are fast and time-saving for construction workers! Relative wet stickers are not as fast as dry stickers!

Comparison of disadvantages: The waste of dry paste glue is relatively large, especially in the dark corners, as well as the upper and lower ends of the wallpaper!

The sequelae of dry stickers are relatively large! Some light switches, as well as baseboards, and the upper end of the wall. will account for glue!

Although Japanese glue, rubber powder and white glue are not very corrosive, they will generally be reflected after 2 to 3 years, and the switch will rot (the seam between the wallpaper and the switch is the most obvious). It's all on the top of the wall! (Dry stickers are not very demanding for construction personnel).

Although wet pasting is a bit complicated, the sequelae will be reduced. I can't guarantee the effect The amount of glue will also be reduced!!

Dry stickers on the wall, wet stickers on glass or extra smooth places.

Generally dry, with adhesive tape, so flat.

It mainly depends on what type of wallpaper you have! An ordinary house can be pasted with a kind of wallpaper with its own glue, and you can paste it directly!

Wet paste was once widely used, but there are certain defects in wet paste wallpaper, and now dry paste is widely used, cement wall, paper gypsum board, calcium silicate board base.

First, the panel is installed with no delamination, warping, cracking, firmness, and lack of edges.

2.The allowable deviation of surface flatness and elevation verticality is, the allowable deviation of the square of the yin and yang angles shall not exceed, and the allowable deviation of the height difference of the seam is.

3.On the light steel keel, tapping screws should be applied to fix the panel, and the nail head should be embedded in the plate and should not damage the paper eye, which plays a role in preventing rust.

4.In a humid place, it can be treated with moisture.

5.Sandpaper polishing, full scraping putty, and base putty should be firm and firm, flat and smooth, without cracks and protrusions, pulverized and peeling, and the line angle should be straight.

Water quality walls. 1.The base layer of the wall should be dry, and the maximum moisture content of the wood base should not exceed 12%.

2.Wooden panels should be fireproof before installation.

3.The knots and pine resin parts on the wooden base should be closed with shellac knees, and the nail holes should be filled with oily putty. Before scraping putty, an alkali-resistant sealing primer should be applied.

4.Full scraping putty, sandpaper polishing, the base putty should be smooth and smooth, solid and firm, there should be no pulverized peeling, cracks and protrusions, and the corners and feet should be straight.

Seam treatment of different material bases.

Seam tapes must be pasted at the joints of different material bases, otherwise they are easy to crack, peeling, etc.

Concrete and cement mortar plastering wall base.

1.Full scraping putty, sandpaper polishing, and base putty should be smooth and bright, solid and firm, and there should be no chalking peeling, cracks and protrusions, and the line angle should be straight.

2.The cement mortar plastering base and the concrete of the old building should be clearly and loosely decorated before the wallpaper is pasted, and the interface agent should be painted.

3.The substrate must be dry, so that the water is as volatile as possible, and the maximum moisture content cannot exceed 8%.

4.Cement mortar plastering base and concrete of new buildings should be coated with alkali-resistant sealing primer before scraping putty.

5.The yin and yang angles and the squareness of the façade shall not exceed the allowable deviation.

6.The concrete wall and cement mortar and the plastering layer between the plastering layers and the plastering base must be firmly bonded, the plastering layer should be free of hollowing, and the surface layer should be free of cracks, delamination and ash blasting.

Nowadays, wallpaper does not need to be wet.

Dry sticking is glue on the wallpaper, and wet sticking is gluing on the wall.

Stickers used to be widely quoted, but wet wallpaper had certain defects, and now dry stickers are widely used.

The dry and wet sticking methods of wallpaper, the dry paste must master the scale of the glue, and at the same time, during the construction, we must also pay attention to certain skills:

First, in order to prevent the wallpaper from mold, the wall needs to be brushed with varnish before paving, and the paint must be dry to prevent the wallpaper from bulging;

Second, special glue should be used, and the ratio should be strictly implemented in accordance with the instructions;

Third, when the wallpaper of the parquet needs to be paved, the flower should start from the middle;

Fourth, when too much glue spills over the surface of the wallpaper, it must be scrubbed with a sponge, not with a towel;

Fifth, after the wallpaper is pasted, open both sides of the wallpaper seam and brush the glue again with a small brush, and at the same time, the seam can not be scrubbed too many times, otherwise the wallpaper will be blackened;

Sixth, if the wallpaper produces a drum, it is necessary to break the drum and put the glue or extract air to inject the glue for treatment. Wallpaper is generally divided into two types: wet and dry. The method of wet paste was once widely used, but there are certain defects in wet pasting, that is, after the bottom paper is soaked in water, it is difficult for the glue to adhere to the surface of the paper, causing the phenomenon of warping.

Nowadays, the method of dry paste is widely used, and its advantage is that after the back of the wallpaper is coated with glue, it is pasted after a few minutes, and the strength is more than double that of wet paste, and there will be no common warping phenomenon on both sides of the seam.

Dear, hello teacher is very happy to answer for you, what I found here is that the paper itself has gravity, macroscopically, there is no interaction between the paper and the wall, there is no atmospheric pressure on the pin, the internal and external air pressure is equivalent, and the air pressure has no effect at this time; When the paper is wet, first of all, it is equivalent to discharging the air between the paper and the wall, resulting in an air pressure difference, there will be atmospheric pressure, friction, counteracting the gravity of the paper, and sticking it to Zheng You.

No, how to do it:

1) Grassroots cleaning: When the base layer is concrete or mortar surface layer, the base layer must be dry and smooth, and the ash and oil stains on the base layer must be cleaned up; When the base layer is gypsum board or wood plywood, the surface is required to be smooth, the board seam is tightly treated, and the nail cap must be deep into the nail hole of the board surface, and the oil slurry putty can not be exposed, so as not to cause rust.

2) Brush the interface agent and scrape the putty: after the base layer is treated, brush an interface agent, and then scrape the water-resistant putty, after the putty is dry, polish it flat with sandpaper, clean it, and scrape a special wallpaper glue.

3) Brush with clear oil: After the base is processed and dried, the surface of the base layer is fully coated with clear oil, which should be thin and uniform.

4) Wall elastic vertical line: pasting wallpaper, the paper width must be vertical, 100mm from the corner of the wall to play the vertical line, as a benchmark to paste the first wallpaper, pasting should be often corrected and adjusted when pasting, keep the paper vertical.

5) Brush glue: Evenly brush the adhesive on the back of the wallpaper and the wall, according to the width of the wallpaper when brushing the glue on the wall, do not brush too wide, brush a paste.

6) Paste wallpaper: paste wallpaper, the paper width must be vertical, first to the flowers, the pattern of the seam, do not show the stubble, the upper end of the line, no margin; Starting from the second piece, the top and then the bottom of the sewing paste, the pasting should be often proofread and adjusted, keep the cloth vertical, and the dark corner seam should be left on the dark side. Then use a thin scraper and cotton silk to press from top to bottom, start from the seam, flatten and compact in order from the outside to the bottom, squeeze the excess binder out of the paper edge, and the extruded binder should be cleaned in time with a wet towel.

7) Clean the finish: The glue and stains on the surface of the cloth should be wiped clean. Carefully inspect the seams, and there can be no "open mouth" warping corners and edges.

No, if there are other decoration aspects or soft decoration matching, display and other problems, you can communicate with the designer Lele in my store, Yimei Natural.

Stickers do not need to be painted.

The foundation is the same as the latex paint, it is necessary to find the yin and yang corners first - scrape the putty base layer to deal with and polish, but it is different here.

Latex paint is a primer and topcoat after sanding.

If you want to paste wallpaper on the wall, you can directly brush the wallpaper base film after polishing, and then paste the wallpaper If it is the first floor, a humid environment, it is indeed not recommended that you paste the wallpaper on the second floor.

Wallpaper is not divided into rural and urban areas, mainly to see is not suitable.

No, the wallpaper is a base film, and there are other things.

No, you can just put it on as if it were tape.
