Ceilings are an overlooked part when it comes to decorating, but they have the ability to completely transform the look and feel of a space. Ceiling panels, especially, can instantly uplift a room, giving it a polished, modern look while also improving acoustics and insulation.
Whether you’re renovating an old space or finishing a new one, understanding the correct installation process is key to achieving a professional result. In this step-by-step guide, you’ll find helpful tips and the essential tools required to make the project easy - even for DIY beginners.
What tools do you need for installing ceiling panels?
Before you start preparing and installing your panels, you’ll need to have the right tools to hand. These tools will make installing the panels easier, as well as help ensure a quality finish.
For this job, you’ll need:
-
A sharp Stanley knife, fine-tooth hand saw, or electric saw
-
Pins, staples or screws
-
A marker pen
-
A ruler
-
A sealant gun
-
A tape measure
How to install ceiling panels
Achieving that professional-quality finish is easier than you think if you follow the right process. Our easy-to-follow guide takes you through every step to ensure a smooth DIY project.
-
Measure your ceiling
Taking the time to carefully measure the ceiling will make the entire project smoother. Ideally, you want the boards to be long enough to cover your ceiling but with little wastage. You can choose between a horizontal or vertical look to suit your style.
You’ll need to work out how many panels you need in total, and you can do this by measuring the length and width of your ceiling using a tape measure. Then divide the width of your wall by the width of the panels (the width of ceiling panels is typically 250mm in width, but you can double-check the product listing if you’re unsure).
example: 1250mm (ceiling width) ÷ 250mm (width of panel) = 5 panels
If you have an uneven number, such as 5.5, you should round it up.
-
Prepare your ceiling
Next, you’ll want to inspect the surface for cracks, loose material, or uneven spots, and patch or sand as needed to create a clean, flat base for installation, wiping away dust and debris so adhesive or fasteners can bond properly. This simple prep work goes a long way toward achieving a long-lasting ceiling finish. You can read more on our blog about how to prep panels for installation to learn more about thorough prep work that guarantees a strong bond.
-
Cutting the panels to size
Using the measurements you took earlier, mark each panel clearly with a pencil and straightedge to ensure precise lines before cutting. Once the back of your panel has been marked with the correct measurements, it’ll be ready to cut down. You can use the following tools:
A Stanley knife - when using a Stanley knife, you’ll want to score along the back of the panel in a straight line where you have marked. Once scored hang it off a sturdy surface and snap off the excess for a clean finish.
A fine-tooth handsaw - a fine-tooth handsaw is a small, lightweight saw designed to make smooth, precise cuts without tearing or chipping delicate materials. Unlike a standard wood saw with large, aggressive teeth, a fine-tooth saw has many small teeth placed close together, which allows it to cut cleanly through ceiling panels.
An electric chop saw - a power tool used for making quick, precise straight cuts through wood, metal, or other building materials. Many chop saws can also be adjusted to cut at angles, making them especially useful for projects that require mitred or bevelled edges. Because of its power and speed, a chop saw is great for cutting multiple ceiling panels.
Take your time with edge pieces, light fixtures, and vents, trimming carefully so everything fits snugly without gaps. Accurate cuts not only make installation easier but also give your finished ceiling a polished, professional appearance.

Cutting around lighting fixtures
Accurate measuring and cutting are key to achieving a clean look when working around lighting fixtures. Start by turning off the power to the fixture for safety, then measure the exact size and position of the opening you’ll need. For this, you’ll need to measure:
-
The diameter of the fixture
-
Where it sits on the ceiling
A hole saw, or jigsaw, works well for round openings, while a utility knife or fine-tooth saw is ideal for square or rectangular cutouts. It’s best to cut slightly smaller than needed at first, then gradually trim for a snug fit around the fixture.
For the best results, you should:
-
Measure directly from the edges of the ceiling grid (or the wall if it’s the first panel) to the centre of the light fixture.
-
Write down the distance from the left/right edges and the distance from the front/back edges. Then, lay your ceiling panel flat on the ground.
-
Using the same measurements, mark those distances on the panel - this will give you the exact centre point for the fixture.
-
From there, trace the outline of the opening you need using the diameter of the fixture to know how big a hole to cut, making sure to leave a small allowance so the fixture can sit neatly without forcing the panel.
-
Cut slowly to avoid cracks or rough edges. Once cut, test-fit the panel around the fixture to ensure a proper fit before securing it in place.
-
Remove the panel groove
Before securing your ceiling panels in place, you may need to remove the panel grooves along the edges to create a smooth, flush fit, especially where panels meet walls or trim. Start by identifying which sides will be exposed or pressed against a border, then use a utility knife, chisel, or fine-tooth saw to carefully trim off the grooved portion.
Cut at around a 45-degree angle and slice from the top to the bottom of the panel to create a straight edge. This allows the panel to be lifted directly into place without needing to slide it into the groove of the adjacent panel. Smoothing rough edges with light sanding can help achieve a cleaner finish and tighter seams. This small but important step ensures your ceiling panels align neatly and deliver a polished, professional result.
-
Apply the adhesive
For this step, begin by choosing a strong adhesive to adhere your panels with. Our guide to sealants and adhesives includes everything you need to know when it comes to choosing the right one for your DIY project. However, as a quick reference, a few of the different options include:
Solvent-free adhesive - solvent-free adhesive is an instant grab adhesive that is best suited for porous surfaces such as existing plaster board, concrete, chip board, wood, etc.
Silicone adhesive - silicone adhesive is ideal for surfaces that are non-porous, such as existing tiles or smooth, shiny surfaces. It’s unlikely that you’ll need this type of adhesive for installing ceiling panels, but if you do happen to choose this kind, you’ll need to ensure that the panel's tongue is screwed into the existing surface every 30cm as you install them, so that they stay in place.
Maximum Torque Adhesive - Torque adhesive is a maximum instant grab adhesive that bonds to basically everything and anything. Using this adhesive will replace the need for screwing & stapling the panels tongue completely on installation.
Once you’ve chosen the best adhesive for your DIY project, you’ll want to insert the canister into an adhesive gun and apply the adhesive in a zigzag pattern, ensuring as much coverage as possible for strong bonding.
If you have an uneven existing ceiling surface, apply more adhesive in the uneven areas to compensate for these areas; this will ensure a smooth, flat surface finish.
-
Install the panels
Begin at one corner of the room, aligning the first panel with your reference lines to ensure it sits straight. Ensure the grooved edge faces the wall where it was cut earlier to achieve a flush finish.
Apply pressure to the entire panel to make sure that the adhesive spreads and that you have a tight seal. If you have chosen to screw, staple or pin your panels to allow for the panel to stay in place whilst the adhesive sets. Once set, you will want to screw, pin, etc, every 30cm for a secure fit.
Continue working row by row, making sure each panel fits snugly against its neighbours, especially along edges and around corners. Take your time to check alignment, frequently consistent spacing, ensuring that the tongue and groove interlocking systems are placed tightly together for a seamless and professional quality look.
-
Add trims
While this isn’t an essential step, adding trims completes a polished look by offering clean edges to the final product. Trims come in a few different types:
Quadrant - These trims can be fitted externally after the panels have already been placed.
Coving trims - are used to conceal and protect edges, seams, and corners. You can also cut the back tongue of this trim off so that the trim finish can be installed externally after all ceiling panels have been installed.
End caps - these are made to slot into the panel whilst the main panel installation is being carried out, and will therefore need to be done during step 6 of our guide.
How to install panel trims:
-
Once all panels are securely in place, measure and cut moulding or decorative trim to fit along the edges where the ceiling meets the walls.
-
Apply a strong adhesive or finishing nails to hold the trim in position, making sure corners are neatly mitred with a mitre block for clean joints.
-
Use sealant on any small gaps between the trim and panels to create a seamless look.
