Plasterboard is one of the most common materials used for creating smooth internal walls and ceilings throughout the UK. But fitting plasterboard is not simply a case of fixing boards to a wall or ceiling. The joints between each individual board need to be reinforced and finished properly to form a strong smooth surface that will not easily crack. This is where the plasterboard joint tape comes in.
Whatever your trade, whether you’re a professional plasterer, builder, decorator or property maintenance company or a DIY enthusiast, the right tape can make a huge difference to the quality and longevity of a plasterboard finish. In this full UK guide we explain what plasterboard tape is, how it works, the different types available, how to use it properly and what to look for when buying it.
What is tape for plasterboard?
Plasterboard tape is a reinforcing material used to cover and reinforce the joints between sheets of plasterboard. If two boards are installed side by side, a small joint or seam remains between them. Weak if not well-reinforced, these areas are susceptible to visible cracks in the future.
The tape is placed on the joint before or during the process of jointing. This encourages a better bond between the boards and provides a flat surface for joint compound, plaster or finishing materials.
Plasterboard tape is an easy way to create a smooth continuous surface from separate plasterboard sheets.
It is especially suitable for new construction, renovations, partition walls, ceilings and repair work in residential and commercial properties.
Why Is Plasterboard Joint Tape Important?
Taping plasterboard joints is more than simply making them look neat. It also helps to improve the overall performance of the finished wall or ceiling.
Plasterboard can move slightly due to changes in temperature, humidity, building settlement and everyday structural movement. If not properly reinforced, these movements may crack.
For plasterboard there is jointing tape to give extra reinforcement over the seam. Used with the right joint compound and application method, it can help you achieve a stronger, more professional finish.
Benefits include:
Reinforcement of plasterboard joints
Helping to reduce the risk of visible cracking
Designing a better surface to finish
Enhancement of the look of walls and ceilings
Enabling plastering work of professional quality
easier joint construction and finishing
For contractors working on multiple projects, reliable tape can also help improve consistency and reduce the need for unnecessary remedial work.
Different Kinds of Plasterboard Tape
When installing or repairing plasterboard, there are different types of tape. The best choice will depend on the application, the type of joint and your preference for finishing.
Paper Joint Tape
Paper tape is a tried and trusted standby for many professional plasterers and plasterboard fitters. It is designed to be embedded in joint compound and when properly installed will give high strength reinforcement.
The beauty of paper tape is that if you do it right you can get a nice professional finish. But you need to prepare and apply it properly to avoid bubbling, wrinkling and poor adhesion.
Fibreglass Mesh Tape
Another popular choice is fibreglass mesh tape, especially for repairs and basic jointing. It is typically sticky backed so that it can be applied straight to a prepared joint.
Mesh tape is easy to handle and apply making it handy for repairs and DIY projects. It is also available in various widths for various applications.
However, users should always check that the particular mesh tape is compatible with the plasterboard system and the jointing compound in use.
Self-Adhesive Plasterboard Tape
Self-adhesive products are designed for ease of placement. The sticky back means the tape sticks to the plasterboard before you apply the jointing compound.
This can save time during installation because the tape does not necessarily have to be held in place while the first layer of compound is being applied.
A good plasterboard repair tape can be particularly helpful for cracks, damaged areas or small sections of plasterboard that need strengthening as it pertains to repair jobs.
How to use joint tape for plasterboard
It is important to apply correctly to get a strong and smooth result. The exact method will vary depending on the tape and jointing system but the general procedure is straightforward.
Surface preparation
Ensure plasterboard surface is clean, dry, free of dust, loose material and contaminants. Damaged edges should be repaired prior to the application of the tape.
A good preparation is important, dust or debris can interfere with adhesion and make finishing more difficult.
Taping Procedure
Place the tape in the middle of the plasterboard joint. If you are using self-adhesive mesh tape, push it down well so it rests flat across the seam.
The method of application shall use paper tape and joint compound specified by the maker of the joint compound.
Apply jointing chemical
Apply a suitable application of jointing compound over the taped seam. Work carefully so the compound covers the tape evenly, and does not leave huge amounts of material.
The idea is to embed and consolidate the tape and provide a surface that can be polished later.
Let Dry
Allow the compound to dry for the manufacturer's specified time. The drying time depends on the product, the thickness of the layer applied, the temperature and ventilation.
Take your time with this process, if you sand or apply another coat too early it can affect the final outcome.
Apply Additional Coats
For a professional finish the jointing compound will usually have to be applied more than once. More treatments will help build the joint up gradually and blend it into the surrounding plasterboard.
When dry the surface can be lightly sanded and is ready for embellishment.
What Is the Best Tape for Plasterboard Joint?
There is no single tape that is the best for every project. The right one depends on the application and on the experience of the user.
Paper tape is a wonderful alternative for professional jointing systems where a strong neat finish is required. Some repairs and applications require ease of installation and mesh tape can be more convenient for such.
When selecting tape for plaster joints, consider the tape width, material, adhesive properties, compatibility with joint compound, strength, and manufacturer recommendations.
For contractors who routinely buy supplies, selecting the proper quantity can also assist control project costs.
How To Use Plasterboard Repair Tape?
Plasterboard repair tape might be useful if there is some existing damage to a wall or ceiling around a seam or small crack.
The cause of the damage must be found before any repair tape is applied. A tiny surface crack may only require reinforcement and finishing, but movement or structural concerns may require a more involved treatment.
A common way to mend little damage to plasterboard is to clean the affected part, remove any loose debris, apply suitable tape, coat with jointing compound, allow it to cure and then finish the surface.
Select a product that is suitable for the repair you are performing and follow the recommendations.
The Most Common Mistakes When Using Plasterboard Tape
A high quality tape may not work properly if installed incorrectly. Common mistakes include:
Applying tape to a dirty surface: Dust and dirt can impact the adhesion and the quality of the joint.
Jointing compound too plentiful: Too much jointing compound can make the joint harder to finish and may mean more sanding.
Tape misplaced: The tape must be applied in such a way that there is reinforcement on both boards over the joint.
Rushing the drying process Apply more layers before the previous layer is dry enough and you can ruin the finish.
Wrong product selection: Different applications require different tape types, so always check compatibility before you begin working.
