    Plastering tape is often overlooked in favour of more glamorous wall repairs tools like paintbrushes and rollers when it comes to making aesthetic improvements to a wall or painting it.

    However, plastering tape is an important element that can dramatically improve the look and longevity of your walls.

    Plastering tape is a multipurpose and essential tool for preventing damage to walls, limiting the need for repairs, and achieving a polished appearance. 

    This blog post will discuss the importance of plastering tape, the different kinds available, and the best techniques for applying and removing it.

    Different Types Of Plastering Tape

    Tapes made of paper, fibreglass mesh, and metal are the most common materials used in plastering. Each variety has its own set of strengths and weaknesses, which makes it well-suited to certain jobs.

    Paper tape is the most common and simple to use, but fibreglass mesh tape is more robust and long-lasting. Concerning exterior corners, metal corner beads are the most reliable and expensive option.

    Before deciding on a plastering tape, evaluating your project's requirements is important.

    Metal Angle Tape

    Plastering tape reinforced with galvanised metal, like the metal angle variety, is a superior product. Metal angle tape is the strongest and longest-lasting plastering tape available, making it perfect for finishing exterior and interior drywall corners.

    The metal angle tape is pre-creased along its length for speedy and easy installation, ensuring that every corner is crisp and square.

    Paper Tape

    When it comes to drywall tape, paper tape is the bare minimum. It's constructed from paper strips that have been coated with an adhesive. Paper tape is versatile and simple to use, making it a smart choice for do-it-yourself tasks. However, it's more sturdy than other plastering tapes, so it might not last as long in the long run.

    Scrim Tape

    When first starting with plasterboards, scrim tapes are a great tool to have on hand. The benefit of scrim tape over regular drywall tape is that you don't need to use jointing compounds. Therefore, this tape requires less maintenance.

    Benefits Of Using Plastering Tape

    There are many benefits to using plastering tape when plastering a wall or ceiling. Some of the most salient benefits are as follows:

    Cracks Are Prevented.

    Plastering tape can help keep your walls and ceilings in pristine condition by sealing off potential cracks before they even form. Joints, corners, and other brittle spots are taped with plastering tape to prevent cracking. When allowed to dry, the plaster and joint compound form a strong bond with the tape, making for a more stable and durable surface. Plastering tape can help you save money on future repairs.

    Improved Aesthetics

    In the absence of plastering tape, the joints between drywall sheets will be visible and difficult to conceal. However, you can get a more polished look and make painting or wallpapering easier by tapping off any imperfections in the wall first.

    Reduced Maintenance

    Plastering tape can delay costly repairs and maintenance by sealing potential points of failure. The result is improved aesthetics and reduced maintenance costs for your walls and ceilings.

    Shrinkage Resistance

    The joint compound shrinks significantly as it dries, which can cause cracking and other defects. Plastering tape aids in avoiding this shrinkage by giving seams extra backing and reinforcement. Once the joint compound has dried, the surface will be smooth and free of cracks thanks to this step.


    Plastering tape is an inexpensive choice for do-it-yourselfers and professionals looking to reinforce drywall seams. Plastering tape is frequently less expensive and more convenient than alternate reinforcement methods, such as metal corner beads.

    Strength And Durability Have Been Increased

    Plastering tape is used to reinforce the joints between drywall sheets to protect them from cracking and damage. In addition, the plastering tape helps create a smooth, defect-free surface by firmly adhering the drywall sheets together.

    Provides A Smooth Surface

    Plastering tape also helps make a smooth surface, which is great for painting. However, plaster or joint compound applied directly to drywall can make smoothing the surface challenging. Using plastering tape to smooth up the surface before painting or staining can save time and effort.

    Easier Application

    Plastering tape is a time-saving tool for both professional and do-it-yourselfers because of how simple it is to apply. When combined with a joint compound, the plastering tape creates a sturdy, simple, and sandable bond.


    The plastering tape has many uses, from simple drywall seams to more intricate corners and edges. Because of its adaptability, it is an excellent choice for any plastering job, no matter how big or small.

    Reinforces Joints

    Plastering tape is useful for reinforcing seams in both walls and ceilings. Since these spots get more wear and tear than the rest of the wall, they are more likely to develop cracks. Plastering tape can reinforce these areas, making walls and ceilings last longer and look better for longer.

    How To Use Plastering Tape

    Plastering tape to reinforce drywall seams and create a uniform surface is a great option. How to properly apply plastering tape is explained in great detail below.

    1. Surface Preparation

    The surface must be thoroughly prepared before the plastering tape is applied. This necessitates drying out and decluttering the region just adjacent to the seam. Also, any loose or damaged drywall should be fixed before taping.

    Use a vacuum cleaner or a soft-bristled brush to remove the dust and dirt. If you need to remove stubborn dirt or grime from an area, wet the cloth first and then wipe it down.

    2. Application Of A Joint Compound

    After the surface has been thoroughly cleaned and allowed to dry, a layer of joint compound should be applied to the seam. Make sure that any voids or spaces are filled in by spreading the compound over the seam with a putty knife and spreading it out evenly.

    3. Plastering Tape Placement

    Plastering tape should then be cut to the correct length for the seam. The tape's length should exceed the seam's length by a small amount to allow for overlap.

    Tape should be applied over the seam carefully, in a centred and straight fashion. Then, carefully press the tape into the joint compound using your fingers or a putty knife.

    4. Joint Compound Coverage

    After the tape has been applied, cover it with another coat of joint compound. Then, using the putty knife, spread the compound over the tape until completely covered.

    It's important to spread the joint compound out evenly. Then, apply even pressure along the length of the tape without tearing it.

    5. Drying Time

    The applied joint compound must be allowed ample time to dry. Depending on the relative humidity and ambient temperature, this may take a few hours or even an entire night.

    After the joint compound has had enough time to dry, the area can be sanded down until it is smooth, and then it can be painted or papered over as desired.

    Plastering tape can be applied with confidence if the surface is properly prepared, and the steps outlined here are followed.

    Common Mistakes In Using Plastering Tape

    Several common mistakes are made when using plastering tape, which can lead to subpar results or even wall damage. To help you avoid making these common blunders, here are some examples:

    Failure To Prepare The Surface

    Not priming the area first is a common oversight when applying the plastering tape. This can refer to anything from not cleaning the surface to leaving dust or debris on the wall to not using enough joint compound. Failure of the tape to adhere properly could lead to cracks or other damage if the surface were improperly prepared.

    Not Giving The Joint Compound Enough Time To Dry

    It takes time to sand or paint after applying joint compound is another common error. If you're in a hurry, the tape might peel or crack, and the surface might be uneven. Take your time and dry the product according to the manufacturer's instructions for the best results.

    Using The Incorrect Type Of Tape

    Plastering mistakes also include using the incorrect tape. There is a wide variety of tapes on the market, and each one serves a unique purpose. The right kind of tape will crack and stick better than others.

    Inside corners and ceilings benefit greatly from paper tape, while flat seams are better served by mesh tape. If you want your project to turn out well, choose a tape that works well with your materials.

    Avoid making this common blunder by learning about the various tape options and how they can be put to use. You can get advice on what kind of tape would work best for your purposes from the employees at your local hardware store. Better adhesion and a sleek appearance are the results of using the right tape.

    Taping Over Damaged Surfaces

    Plastering tape may not adhere properly or leave a smooth finish if applied over imperfections such as cracks or holes. Therefore, before applying the tape, any damage to the surface must be repaired.

    Not Using A Primer

    Priming the surface makes the paint adhere better and keeps it from cracking and peeling for longer. Follow the primer's application instructions to the letter, and wait for it to dry before painting.

    The Tape Is Overlapping.

    Plastering tape that is overlapped in an effort to cover more ground more quickly may end up creating a weaker joint. Overlapping the tape may result in a thicker layer of joint compound that takes longer to dry, and the excess compound may cause the tape to shift or wrinkle, resulting in cracks and weak spots.

    Use separate tape for each seam or joint to avoid this common error. Instead, use multiple strips of tape, putting them together without overlapping, to cover a larger area. By doing so, you can avoid using too much joint compound, which can weaken the joint and lead to issues.

    Excessive Or Insufficient Joint Compound Application

    Applying the proper amount of joint compound over the tape is essential. Tape that doesn't stick because the joint compound was applied too thinly or too thickly is a common problem. That's why it's important to adhere to the manufacturer's guidelines when applying joint compound.

    Using Insufficient Coats Of Joint Compound

    The failure to apply sufficient layers of joint compound is another frequent blunder when working with plastering tape. If you don't use enough joint compound to cover and smooth out the tape, you'll end up with an uneven surface and poor adhesion.

    Avoid this by applying the joint compound in several thin coats. Apply a thin coat of compound all over the tape, spread it out so it dries evenly, and then move on to the next coat. Do this until the surface is uniform and smooth.

    When applying the compound, take care not to use too much for each coat, as this will cause the compound to dry slowly and possibly crack or peel. However, applying several light coats will result in a durable and uniform coating for your walls.

    Rushing The Job

    Applying plastering tape too quickly can result in a sloppy finish or even wall damage. Before sanding or painting, ensure the surface has been properly prepared, the tape has been applied, and the joint compound has dried.


    The use of plastering tape is essential for maintaining the integrity of walls, reducing the frequency of repairs, and presenting a professional appearance. The materials used in its construction—paper, fibreglass mesh, and metal—each have their advantages and disadvantages.

    Paper tape is the most common type since it is inexpensive and easy to work with, but fibreglass mesh tape is more durable and will last longer.

    Metal angle tape is the best option for finishing drywall corners both inside and out because it is the most durable and sturdy plastering tape on the market.

    Paper tape is convenient because of its adaptability and ease of use, but its durability is questionable.

    Because it eliminates the need for jointing chemicals, scrim tape is an excellent tool for first-time plasterboards.

    Cracks are less likely to appear, aesthetics are enhanced, maintenance is decreased, costs are cut, strength and durability are increased, the application process is simplified, and the tape is versatile and strong.

    As cracks tend to appear around wall and ceiling joints, this material is helpful for fortifying those spots.

    Proper surface preparation, priming, using individual tape for each seam or joint, applying joint compound in many thin coats, and ensuring the surface is properly sanded or painted before sanding or painting are all necessary to ensure satisfactory results and prevent wall damage. If you follow these instructions, your plastering project will turn out beautifully and last for years.

    FAQs About Plastering Tape

    Paper tape and fibreglass mesh tape are two types of joint drywall tapes used in construction. The main difference between them is the material they are made of. Paper tape is made of paper and has a crease down the middle, which allows it to fold and fit into corners easily. It is generally used for inside corners and is applied with a joint compound.

    Fibreglass mesh tape, on the other hand, is made of woven fibreglass material and does not have a crease down the middle. It is generally used for taping drywall joints and has a self-adhesive backing, which makes it easier to apply than paper tape.

    No, it would be best if you did not use plastering tape on a damp surface. Plastering tape is designed for dry surfaces, as moisture can weaken the bond between the tape and the surface. If you apply plastering tape to a damp surface, it may not stick properly, leading to a weak and ineffective joint.

    Before applying the plastering tape, ensure the surface is dry and free from moisture or dampness. If the surface is damp, you should wait for it to dry completely before applying the tape. In some cases, it may be necessary to address the source of the dampness and fix any leaks or moisture issues before proceeding with the plastering.

    Plastering tape can last many years if applied correctly and kept in good condition. However, the exact lifespan of plastering tape can vary depending on factors such as the quality of the tape, the conditions it is exposed to, and the amount of stress it undergoes. In general, replacing the plastering tape if it becomes damaged or begins to peel is recommended, as this can compromise its effectiveness in providing a smooth and seamless finish to drywall joints.

    Yes, it is generally necessary to use plastering tape on every joint when finishing drywall. The plastering tape helps to reinforce the joint and prevent cracking or separation over time. Without tape, the joint could be more prone to damage from movement or settling of the structure. Therefore, it is recommended to apply plastering tape to every drywall joint before applying joint compound and finishing the surface.

    Yes, you can paint over the plastering tape. After applying the tape and joint compound, allow the joint to dry completely before sanding and painting. Once the joint is painted, the tape should be barely or not visible, and the surface should look smooth and seamless. Be sure to use high-quality paint appropriate for the surface and follow proper painting techniques to achieve the desired finish.
