Glass Splashback Installation: A Complete Guide

You can fit a glass splashback by preparing a clean, flat wall, applying a compatible adhesive and carefully positioning the glass. Accurate measurements and safe handling help you achieve a neat, secure finish.

Before you begin your glass splashback kitchen project, check the splashback’s glass type, cut-outs and fixing requirements, especially if it will sit behind a hob. With the right preparation and attention to detail, you can plan the fitting and finishing steps with confidence.

Planning and Preparation

Accurate measurements, correctly positioned cut-outs and a clean, sound wall help your glass splashback fit safely and neatly. Plan around your worktop, cupboards, sockets and hob before ordering the panel.

Measure the Wall and Order the Glass

Measure the width and height of each wall section at several points. Walls and worktops can be uneven, so use the smallest measurement for the panel dimensions and check the supplier’s fitting tolerances. Record where the splashback meets cupboards, corners and other panels, and allow for any expansion gap specified by the manufacturer.

Measure from the finished worktop surface to the underside of the cabinets. Confirm whether the glass will sit behind or above the worktop, and give the supplier a clear drawing with dimensions and orientation. Check all measurements before placing your order, as toughened glass cannot be cut or drilled after manufacture.

Check Socket Cut-outs and Hob Clearances

Mark each socket, switch, pipe and other obstruction on your drawing. Measure the cut-out positions from fixed edges, such as the panel’s bottom and side, and confirm the dimensions with the supplier. Check that socket faceplates will cover the openings and that you can safely isolate the electrical supply before removing them for fitting.

Check the appliance manufacturer’s instructions for the required clearance between the hob and the glass. Heat limits depend on the splashback material and the appliance, so confirm that your panel is suitable for the intended position. Ask the supplier or installer to verify cut-outs and clearances before manufacture.

Prepare the Wall Surface

Remove grease, dust, loose paint and wallpaper from the wall. Repair cracks and holes, then make sure the surface is flat, dry and sound. Uneven areas can leave gaps behind the glass or prevent adhesive from bonding properly.

Check that the wall finish is compatible with the adhesive recommended for your splashback. Apply primer if the adhesive manufacturer requires it, and let it dry fully before fitting. Protect the worktop and nearby units, and keep the panel upright in its packaging until you are ready to install it in your glass splashback kitchen.

Fitting and Finishing

Use the adhesive specified for your splashback and wall surface, then position the panel carefully and support it while the adhesive sets. Finish by sealing the edges with a suitable kitchen or bathroom sealant, following the product’s curing instructions.

Apply the Recommended Adhesive

Check the splashback manufacturer’s instructions for the correct adhesive. Use a product approved for glass and suitable for your wall surface, and confirm that it can withstand the heat where the panel will sit. Avoid solvent-based adhesives unless the manufacturer explicitly approves them, as they can damage the backing or finish.

Make sure the wall is clean, dry, flat and free from dust, grease and loose paint. Apply the adhesive in vertical beads or fixing points as directed by the product instructions, keeping it clear of the panel’s edges and any cut-outs. This helps prevent adhesive from squeezing into view when you press the glass against the wall.

Position and Support the Panel

Plan how you will lift and place the splashback before applying adhesive. For any glass splashback kitchen installation, use a second person to help handle larger panels, and wear gloves to protect both your hands and the glass. Align the panel with your worktop, cabinets and socket cut-outs, then bring it gently into position.

Press evenly across the surface so the adhesive makes contact without stressing the glass. Don’t force the panel into place or use it to compensate for an uneven wall. Use temporary supports or spacers at the bottom if needed to keep the panel level while the adhesive sets, following the manufacturer’s fitting instructions. Check the alignment before the adhesive begins to cure.

Seal the Edges and Allow to Cure

Once the adhesive has set for the time stated by its manufacturer, seal the exposed joints with a compatible, mould-resistant silicone sealant. Apply a neat, continuous bead along the worktop joint and any other edges that need protection from water. Keep sealant out of areas that must remain open for ventilation or appliance clearances.

Smooth the bead with a suitable finishing tool, then remove excess sealant before it skins over. Leaving the glass splashback kitchen area undisturbed for the full curing period ensures a durable bond. Avoid cleaning the glass or exposing the joints to water until both products have cured.
