How to install an acrylic splashback
Measure up and cut your splashback
Cut the acrylic to size
Mark out the power points
Measure the width and height of the power points and transfer those measurements onto the front of your splashback. You'll avoid splintering and have more control over the cut. Drill some holes where the cut outs are going to be. Then use a jigsaw for an accurate cut.
Fix the splashback to the wall
Leave splashback to dry
