XPS Coving Cornice WM27 Internal Corner 20cm, Paintable Ceiling Moulding

• CLEAN FINISH ON INSIDE CORNERS - Pre-shaped sections meet neatly where two walls turn inwards, closing the awkward junction that usually leaves a visible gap in a coving run
• IDEAL FOR FIRST-TIME FITTERS - No mitre box, protractor or angle measuring is required, so the trickiest part of a coving job is handled without wasted material or repeated trial cuts
• PAINTABLE SMOOTH FINISH - The closed white surface takes water-based emulsion directly, so the corner disappears into the run once painted alongside the straight lengths
• LONG-LASTING QUALITY - Moisture-resistant extruded polystyrene holds its shape in kitchens, bathrooms and hallways without warping or crumbling, keeping the profile crisp year after year
• SUPPLIED AS 2 SEPARATE 20CM SECTIONS - The corner arrives as two unjoined pieces that you position and fix on site, so each side can be adjusted to suit walls that are not perfectly square

Every room has them, and they are the corners people notice. Where two walls turn inwards, the coving has to change direction cleanly or the eye goes straight to the gap. Cutting internal mitres by hand is the part of the job that defeats most first-time fitters, and a corner that is slightly out cannot be filled convincingly once the paint is on. This internal corner is shaped at the factory, so the turn is already made. You fit it into the corner, run the straight lengths up to it on both sides and carry on. No mitre box, no protractor, no measuring the angle of a wall that was never quite square to begin with, and no length ruined by a practice cut. WOLDECOR supplies the corner as two separate sections instead of one fixed piece, and that choice matters in real houses. Internal angles drift from ninety degrees as buildings settle, so two independent halves let you push each face into its own wall, close the join by eye and fix them exactly where the room allows. Made from the same extruded polystyrene as the straight lengths, the corner is light enough to hold with one hand while the adhesive takes, trims with a sharp craft knife if a face needs easing, and fixes with ordinary coving adhesive. The closed white surface takes water-based emulsion directly, so once the run is painted the corner reads as part of a single continuous line rather than a separate part. Because the material does not absorb moisture, it holds its shape in kitchens, bathrooms and hallways and will not swell or crumble along the edges over time. This listing is for the internal corner only, supplied as two separate 20cm sections. Straight lengths, external corners and a sample piece are listed separately, so you can order one corner per internal angle and complete the room in a single WOLDECOR order.
