Using adhesive tapes
Adhesive tapes are a popular choice for adhering plastic sheets to walls. Here is a step-by-step guide on how to use adhesive tapes for this purpose:
Prepare the Wall and Plastic Sheet
Before you begin, ensure the wall is clean, dry, and smooth. If there is moisture on the wall, use a hairdryer to eliminate any condensation. Also, ensure the plastic sheet is cut to the required size and free of any dirt or debris.
Choose the Right Adhesive Tape
Select a tape suitable for your surface and project. For example, if you're applying the plastic sheet to a painted wall or window frame, consider using a two-sided product like Dust Containment Tape. This tape is designed to hold poly sheeting against walls and painted surfaces without leaving residue or lifting paint. The blue side of the tape adheres to the wall, while the duct tape side holds the poly sheeting in place.
Apply the Tape
Start by cleaning the wall surface to ensure it is free of dust or grime. Then, apply the adhesive tape around the perimeter of the area you wish to cover. If using a two-sided tape, remove the backing liner to expose the adhesive.
Adhere the Plastic Sheet
With the tape in place, carefully align and press the plastic sheet onto the exposed adhesive. Work from one side to the other, smoothing out any bubbles or creases as you go. Ensure the sheet is securely adhered to the tape and that all edges are sealed.
Finishing Touches
Once the plastic sheet is in place, you may need to apply tape around the edges or seams to ensure a tight seal. If you're working around a door, for example, tape the top, left, right, and bottom sides to create a containment area.

Nails and thumbtacks
When using nails and thumbtacks, you will need to decide on the placement of your plastic sheet and mark the spots where you will be driving the nails or thumbtacks into the wall. It is important to use the right type and size of nails or thumbtacks for your specific wall type and the weight of the plastic sheet you are hanging. For nails, you will typically need a hammer to drive them into the wall. Start by holding the nail in place with your non-dominant hand and the hammer in your dominant hand. Gently tap the nail head with the hammer to start driving it into the wall. Increase the force of your hammer swings as needed, being careful not to bend the nail. If using thumbtacks, you can usually push them into the wall with your thumb, although a small hammer can also be used for more force and precision. Drive the nails or thumbtacks partially into the wall, leaving enough space to hang the plastic sheet. Place the sheet against the wall, lining up the pre-made holes with the nails or tacks. Gently lower the sheet onto the fasteners, taking care not to bend or tear the plastic. Once the sheet is in place, you can use your hand or the hammer to gently tap the nails or tacks further into the wall as needed to secure the sheet. Be careful not to apply too much force, as this could damage the plastic. Nails and thumbtacks provide a secure and removable option for hanging plastic sheets, making them a versatile choice for temporary or frequently changed displays.

Plastic wall hangers
To clean the wall, mix a dilution of water and trisodium phosphate (TSP) in a bucket, following the instructions on the TSP for the correct ratios. Use a scrub brush to thoroughly scrub the wall, then rinse the bucket and fill it with clean water. Wipe down the wall with a sponge or cloth, and let it dry completely before proceeding.
Once the wall is prepared, you can install the plastic wall hangers. Hold the hanger against the wall, ensuring full contact between the hanger and the wall. Use a hammer to drive the pins of the hanger straight into the wall until they are flush with the base of the hanger. These hangers are ideal for hanging small decor and everyday items.
If you are looking for a solution to hang larger or heavier items, there are other options available. For example, you could use a combination of adhesive methods, such as construction adhesive, and the pole method mentioned earlier. This involves suspending the plastic sheet from a horizontal pole with vertical poles at each end to remove the shear forces from the adhesive.
Additionally, consider the type of wall you are dealing with. If you are working with drywall, for example, plastic hooks may not be suitable, and you may need to explore other options such as adhesive methods or alternative hook materials.
Remember to always test the weight capacity of the hangers or adhesive methods you are using to ensure they can safely support the items you intend to hang.

Putty and suction cups
If you're looking for a cheap and removable solution to adhere a plastic sheet to a wall, putty and suction cups can be an option, but this method is not always reliable. Here are some things to consider and steps to follow:
Preparing the Wall and Plastic Sheet:
- Ensure the wall is smooth enough for suction cups to work effectively. Suction cups create a vacuum to adhere to surfaces, and rough walls can prevent a tight seal.
- Clean the wall thoroughly to remove any substances such as mold, grease, or dirt. A diluted mixture of water and trisodium phosphate (TSP) can be used for effective cleaning.
- Measure the area you need to cover with the plastic sheet. Add a few extra inches to each length to allow for overlapping.
- Cut the plastic sheet according to your measurements. It's recommended to trace the measurements with a marker first to ensure straight cuts.
Using Putty:
- If the wall is affected by condensation, dry it with a hairdryer before applying the putty. This will help the putty stick and prevent further condensation from getting between the putty and the wall.
- However, be cautious when using large sheets of plastic, as they can trap moisture and cause mold issues.
Using Suction Cups:
- Clean both the suction cups and the wall surface with soap and water to ensure they are free of dust, dirt, and grease.
- Dry both the suction cups and the wall completely. Water droplets can interfere with the vacuum seal of the suction cups.
- If the wall has a greasy or slimy film, use white vinegar or rubbing alcohol for cleaning. This step is especially important if the wall is in an area like a shower or kitchen, where grease buildup is common.
- Moisten the inner wall of the suction cups with a small amount of water to enhance their grip. This trick works because a little moisture boosts the suction cup's ability to create a vacuum.
- Press the suction cups firmly and evenly against the wall, expelling as much air as possible. Trapped air can weaken the vacuum seal, leading to a weaker hold.
- For an even stronger seal, apply a thin layer of oil or petroleum jelly around the rim of the suction cups before pressing them against the wall. This helps fill in microscopic gaps, creating a tighter vacuum.
- Ensure that the plastic sheet is securely attached to the suction cups and that the cups are firmly adhered to the wall.
While putty and suction cups can be a creative solution for adhering plastic sheets to walls, they may not always provide a strong and long-lasting hold, especially on rough or uneven surfaces. It is essential to test and ensure the security of your setup to avoid any unexpected issues.

Cleaning the wall
Preparing your wall properly is essential for adhering plastic sheets to it. Here is a detailed, step-by-step guide on cleaning the wall before attaching plastic sheets:
Before you begin, ensure you have the necessary safety equipment, such as gloves and safety goggles, to protect yourself from any chemicals or debris.
Start by inspecting the wall for any substances that need to be removed, such as mould, grease, or sand. These substances can interfere with the adhesion of the plastic sheets. Mix a dilution of water and trisodium phosphate (TSP) in a bucket, following the instructions on the TSP packaging for the correct ratios. Using a scrub brush, dip it into the diluted TSP solution and thoroughly scrub the wall. Pay close attention to any areas with stubborn stains or build-up.
Next, rinse the bucket and fill it with clean water. Dip a sponge or clean cloth into the water and thoroughly wipe down the entire wall surface. Ensure that all traces of the TSP solution are removed. Allow the wall to air dry completely before proceeding. This step is crucial, as any remaining moisture can affect the adhesion process.
Once the wall is dry, you can further prepare the surface by sanding it lightly. This will create a smoother surface for better adhesion. Use fine-grit sandpaper and work in gentle, even strokes across the wall. After sanding, remove any dust or debris with a soft brush or cloth.
Finally, if you're working with a porous surface, such as concrete, you may need to apply a primer to the wall. This will help create an even base for the adhesive to adhere to and improve the overall bond strength. Follow the instructions on your chosen primer for proper application techniques.
By following these steps, you will effectively clean and prepare your wall for adhering plastic sheets. Remember to take your time and work carefully to ensure the best results.

There are several methods to adhere a plastic sheet to a wall. One way is to use tapes like blue painter's tape, green tape, or double-coated tape. Ensure that half the tape is on the sheeting and half is on the wall. For added strength, use a thicker painter's tape. Alternatively, you can use plastic wall hangers, thumbtacks, or command adhesive picture hanging strips. If you are adhering the plastic sheet to a concrete wall, you can use construction adhesive, galvanized flashing, or alkaline copper quaternary pressure-treated furring strips along the edges of the plastic.
Plastic wall hangers, also known as poly hangers, are designed to have a firm grip and can support one or more layers of plastic sheeting. They are simple to install, remove, and reuse. Poly Hanger 1 slips behind wall molding and is supported by the vertical leg of the molding. Poly Hanger 2 clips over the horizontal leg of acoustic ceiling wall molding. Poly Hanger 3 supports vertical plastic sheeting for full containments, while Poly Hanger 4 includes a cable release tie for versatility.
If you are looking for a removable and damage-free solution, avoid using pins, nails, or drilling holes into the wall. Instead, consider using adhesive putty, especially if the wall is smooth enough. However, ensure that the wall is dry before applying the putty. Suction cups can also work, but they are not suitable for rough or very dry walls. If you are using tape, opt for a gentler option like blue painter's tape to avoid damaging the paint.
