Splashback Installation Guide

Complete instructions for installing your splashback

Once the area for your splashback has been measured and you have taken delivery of your cut to size splashback, installation is the final step of the process. While it may be daunting, particularly for those new to DIY projects, you’ll be surprised at how easy it is and how quickly it can be fitted into place.

Before you get started, consider the following:

  • Don’t install acrylic panels behind a gas hob and allow a 50mm distance from electric or induction hobs to avoid damage to your splashback.
  • Where a direct heat source is present, such as with a gas hob, you should opt for a glass splashback instead of acrylic.
  • Because of the temperature variations in kitchens and bathrooms, the panels will expand and contract slightly, so they should always be installed with a 2mm gap to allow for this movement.
  • If you’re storing your splashback for any length of time, try not to do so outside or in extreme temperatures as this can cause the panel to bend or distort. Make sure the panels are stored flat.
  • If you’re installing the panels over existing tiling, check that the tiles aren’t loose or cracked as this can lead to the splashback not adhering properly to the wall or distortion of the final result.
  • Use a low modulus silicone adhesive when fitting your splashback and allow a minimum of 24 hours for the silicone to cure before carrying out any further work on your splashback.
  • Ensure that the walls or surface behind the splashback is sealed and non-porous, sealing any boarding panels as well.

Preparing the splashback for installation

If you have chosen to cut your own cutouts, please follow the instructions below. Make sure you keep the protective film on the acrylic until the last moment.

Mark out the area to be drilled or cut

Before you drill or cut your panel, make sure you’re wearing appropriate eye protection and thick gloves as the sides of the panel may be sharp. Make sure that you’re marking the panel in the same environment as where the panel will be fitted, as expansion or contraction from different temperatures might affect the final size of the panel. Mark out the area using a soft felt-tipped pen but be careful not to scratch or scribe the panel itself. You can use masking tape to avoid this. Double check your measurements before carrying out any work to be extra sure you’re drilling the correct area.

Cutting your splashback panel

When cutting holes for power sockets or other small cut-outs, always use a drill and don’t allow the blade to overheat as this can cause the acrylic to melt. Always use a sharp blade to avoid the material from chipping and cut at a steady speed and pressure, cleaning the swarf away regularly so as not to damage the panel. Ensure the panel is firmly fixed to a table or work platform using soft grip C clamps to reduce the vibrations.

Drilling your splashback panel

Once you’ve ensured the markings are in the correct place, you can begin drilling using a wood drill bit which has a steeper angle than a regular drill bit. Don’t choose a sharp metal drill bit as this can chip or crack the plastic. A stepped cone drill bit can be used to bore holes too. Larger holes drilled close to the edges of the panel can reduce the rigidity and strength of the panel overall, and could result in damage to the acrylic, so we don’t advise drilling holes any closer than 20mm from any edge.

To begin, drill a small pilot hole to be completely sure the placement is correct then slowly build the size using slightly larger drill bits until the required diameter is achieved. We recommend supporting your panel on a table or work platform using soft grip C clamps so that the risk of bending or breaking is reduced and apply only a light pressure when drilling. For a secure fit, drill a clearance hole through the panel and then fix the item to the wall behind – don’t use screws to fix items to the panel.

Finishing the edges of your splashback

Acrylic can be sharp when cut, so it’s important to finish the edges with medium grit sandpaper or a file, then finish off with a finer grit sandpaper to smooth the surface and make it safer to work with. Avoid sanding the front of the panel as this can lead to scratches and abrasions – a sanding block is the best tool for the job to achieve an even finish.

Installing the splashback

Installing over existing tiled walls

Splashbacks can be installed over existing tiles, providing they’re securely attached to the wall and there are no cracks or broken tiles which might impact the adhesion of the panel. Make sure the tiles are level with no high spots and remove any uneven tiles which might distort the final surface of the splashback. You should also check the tiles have been thoroughly degreased, cleaned and dried before fitting the panel as per the instructions below. Any exposed tile edges can then be finished with silicone or finishing trims.

Guide to installing your splashback

  1. Check the surface the panel is being fitted to is clean and free from dirt, dust, grime, loose paint and wallpaper.
  2. Test fit the splashback by ensuring there is room for movement and expansion around the sides of the panel.
  3. Apply beads of low modulus silicone sparingly in wavy lines across the panel, ensuring there’s an even coverage and that there’s a bead of silicone around the aperture for any cut-outs or holes. Make sure the silicone is not too close to any edges
  4. Using spacers under the panel to allow for the expansion gap, guide the bottom of the panel to the correct part of the wall and move the top of the panel towards the wall, applying firm pressure to fix it into place
  5. Apply pressure firmly with your hands across the whole of the panel to make sure it’s securely fastened and that the panel has decent contact with the wall
  6. Wait 24 hours to allow the silicone to cure before removing the spacers
  7. Use masking tape to mask the edges of the panel and then seal the expansion gaps using an appropriate sealant, removing the excess with a silicone finishing tool and smoothing with a mild solution of soap and water
  8. Once the edges are smoothed, you can remove the masking tape, making sure the room is well ventilated to allow the sealant to dry properly
  9. Remove the other protective film from the front of the acrylic

Cleaning your splashback

Cleaning acrylic splashbacks is incredibly easy – it can be done using just a soft cloth and warm, soapy water. Don’t use scouring pads or chemical cleaners and never rub the panel if the surface is dry, as this can scratch the panel. If you need to remove silicone or stronger substances from the splashback, a small amount of Turpentine on a lint-free cloth usually does the job.
