Polycarbonate kitchen backsplash installation.

Are you planning to install a DIY kitchen splashback?

It’s essential to determine which installation method is most suitable for your kitchen splashback before you start. You have to attach an opaque kitchen backsplash differently from a transparent or semi-transparent panel. This blog gives you tips for installing both an opaque and a transparent DIY kitchen splashback.


To install a kitchen splashback, you’ll need:
  1. Plastic sheet custom cut to size

  2. Burnus plastic cleaner

  3. Burnus plastic cleaner

  4. Mounting adhesive or spacers

  5. (Optional) jigsaw or router

  6. Silicone sealant



The basics of kitchen backsplash installation.

It’s easy to fix an opaque kitchen splashback with mounting adhesive. When attaching a transparent or semi-transparent polycarbonate sheet, it’s best to use special spacers. Follow the steps that correspond to the kitchen splashback you’ve chosen.



Step 1: Ensure the surface is clean and flat

Before you get started, the wall on which you’re going to mount the splashback must be clean and flat. If you’re glueing the splashback over old tiles, make sure the surface is entirely free of grease. And remove any old sealant residue before you do anything else.


Step 2: Make cut-outs for the sockets (optional)

If you’re going to use a router on the socket cut-outs yourself, proceed as follows:


  • Measure the position and measurements of the sockets. Measure tightly because it’s always possible to file or sand them.

  • Draw the cut-outs on the protective film of the polycarbonate sheet and then apply masking tape.

  • Take a metal drill and drill a starting hole in one corner.

  • Now you can cut the recess for the socket with a jigsaw or router.

  • Check that the recesses are correct and tidy them up where necessary with a file or sandpaper.



Step 3: Apply sealant to your opaque kitchen splashback

If your kitchen splashback is transparent, skip this step and go on to step 5. Apply stripes and dots of sealant adhesive to the back of the plastic sheet, but not too close to the edges. First, remove the protective film from the polycrbonate sheet and clean the sheet with an anti-static cleaner. Is your kitchen splashback an Polycarbonate panel? If so, we recommend using High Tack Premium H980 mounting adhesive.



Step 4: Stick the panel to your kitchen wall

Slide your panel carefully into the correct position, being careful not to scratch the counter top. Don’t press the panel against the sealant straight away, but place it in the right position first. Now press the panel against the wall working from the centre. Let the mounting adhesive cure for 24 hours, and then remove the spacers (if you used them).


Step 5: Drill holes in your (semi-)transparent kitchen polycarbonate backsplash

Have you opted to install a transparent polycarbonate splashback in your kitchen? Then, of course, it won’t look good if you attach it with mounting adhesive. So instead of mounting glue, use special spacers you can find on Amazon or panel holders. Do you need a few tips on drilling transparent polycarbonate sheet?

Step 6: Seal your kitchen splashback

Whether you’re installing an opaque or transparent kitchen splashback, you need to seal it to create a neat and watertight finish. Use silicone sealant in the correct color for this job.

Tip: Do you find it tricky to apply sealant neatly? Apply masking tape to the worktop and bottom of the plastic sheet so that the sealant only goes in the right place.
