When removing wall stickers, the hot air blower softens the adhesive layer by heating, making it easier to peel off the stickers and reducing damage to the wall at the same time. The following are the detailed steps and precautions for using a hot air blower to remove wall stickers:
First, the operation steps
1. Preparations
Tool preparation:
Hot air blower (It is recommended to choose a model with adjustable temperature and stable wind speed)
Plastic scraper (or credit card, plastic shovel)
Cleaning cloth, warm water, neutral detergent
Protective gloves (to avoid high-temperature burns)
Environmental inspection
Make sure the wall surface is free from damage, powdering or severe unevenness.
Turn off the power to avoid hot air blowing directly onto sockets or electrical appliances.
2. Heat and soften the stickers
Adjust the parameters of the hot air blower:
Temperature: Set at 150-200℃ (Adjust according to the material of the sticker. Use low temperature for ordinary paper stickers and high temperature for plastic stickers).
Wind speed: Medium to low. Avoid excessive wind speed causing heat dispersion.
Uniform heating
Keep the hot air blower 5 to 10cm away from the wall and move it slowly in a circular motion to ensure that the stickers are heated evenly.
Heating time: Approximately 30 to 60 seconds for every 10×10cm area. Observe whether the edges of the sticker curl or the adhesive layer softens.
3. Peel off the stickers
Start from the edge:
Gently pick the edge of the sticker with a plastic scraper or your fingernail. If the adhesive layer has softened, you can slowly tear it off.
If the sticker breaks, reheat the area and continue peeling it off.
Avoid forced tearing:
If the sticker is not completely softened, forcibly tearing it off may cause the paint on the wall to peel off or leave glue marks.
4. Remove the remaining glue marks
Heat the residual glue:
Repeat the heating step for the remaining glue marks. After softening, gently scrape them off with a scraper.
Use detergent:
If the glue mark is stubborn, you can use a small amount of neutral detergent (such as alcohol or white vinegar) to moisten the cleaning cloth and gently wipe it.
Avoid using sharp tools or strong acid or alkali solvents to prevent damage to the wall surface.
5. Wall repair and cleaning
Fill the small potholes:
If small pits appear on the wall due to the tearing of stickers, they can be filled with putty. After it dries, it should be sanded smooth.
Overall cleaning
Wipe the wall with a damp cloth to remove dust and detergent residues, and ensure the wall is dry.
Second, precautions
Safety protection:
Wear protective gloves to avoid scalding from high temperatures.
When operating, keep the hot air blower stable to prevent scalding the walls or furniture.
Temperature control
Avoid heating the same area for a long time to prevent the wall from discoloring or getting burnt.
For latex paint walls, the temperature should not exceed 200℃. For wallpaper walls, a lower temperature (about 120-150℃) is required.
Material adaptation
Plastic stickers (such as PVC) require a higher temperature, while paper stickers can be used at a lower temperature.
Metallic texture stickers or thick adhesive stickers need to be heated multiple times and peeled off gradually.
Environmental ventilation
Keep the area well-ventilated during operation to avoid discomfort caused by the accumulation of hot air.
Third, Summary
The core of using a hot air blower to remove wall stickers is “heating and softening, then gradually peeling off”. By reasonably adjusting the temperature and wind speed, and in combination with the correct operation methods, stickers can be efficiently removed and wall damage can be reduced. When operating, pay attention to safety protection, temperature control and material compatibility. If any problems occur, adjust the method in time or seek professional help.
