Upgrade your panel installation with the White Internal Trim (5/6mm) – the perfect choice for achieving clean, seamless internal corners while adding long-lasting protection.

Matching trim to panel

A trim is made for a set panel thickness, so check the thickness of your panels before you order: a trim made for thinner panels will not take a thicker one, and one made for thicker panels leaves a loose fit. Trims like the white internal trim are listed with the panel thickness they suit.

Measuring up

Measure every corner, edge and join that needs a trim, and add a little extra for cutting. Plan corners so that cut ends sit out of sight where possible. A quick sketch of each wall makes it easy to see how much of the white internal trim you need.

Cutting tips

A fine-toothed hacksaw gives a clean cut, and a mitre box helps where two trims meet at an angle. Smooth any rough edges with fine sandpaper or a file before fitting. Cut this way, trims like the white internal trim fit neatly against the panels.

Fitting and sealing

Dry-fit the trim and panels together first. Use a suitable adhesive, and in wet areas run a thin bead of silicone sealant along the joint to keep water out. Fitted this way, trims like the white internal trim protect the panel edges for years.

Cleaning and care

Wipe trims with a soft damp cloth and a little mild detergent. Avoid abrasive cleaners and scouring pads, which can scratch the surface. Cared for like this, trims like the white internal trim keep their clean finish.

Why trims matter

Trims hide cut edges, cover small gaps and protect corners from knocks, and they help keep water away from the panel edges in wet areas. A few metres of a trim like the white internal trim make a panel job look professional.

Choosing a finish

Chrome-effect trims add a bright accent that stands out against plain or dark panels and goes well with chrome taps and shower fittings. White trims blend in with light panels and keep the look simple, and black trims give a bold contrast against light panels or suit dark ones. Whichever you pick, a trim like the white internal trim ties the room together.

Tools for the job

A tape measure, a pencil, a fine-toothed hacksaw, a mitre box, a sealant gun, adhesive and silicone sealant cover most trim jobs. Keep a damp cloth to hand to wipe away excess sealant before it sets. With these ready, fitting a trim like the white internal trim is a quick job.
