Our led plaster profile inside corner is one of the best aluminum channels for installing plaster in drywall and plasterboard internal corners. This trimless internal corner channel DWP04 hides all the hardware and lighting parts, giving you a clean stream of light with no visible edges or trims. The cross-section shows an uneven V-shape that fits well in a 90-degree corner. The main specifications are 46mm wide, 25.5mm deep, and 9.7mm wide for the internal strip attachment. It is smartly utilized to light up the spot where two walls meet, sending a soft, indirect beam of light that washes over the walls below. This design is great for adding gentle lighting effects to buildings.
Why Choose Our LED Plaster Profile Inside Corner?
- Trimless and Recessed: Plastering over the holes in the flanges gives the profile a clean, modern look.
- Perfect Inside Corners: Made just for 90° internal drywall corners, these are great for walls that meet ceilings or walls that meet walls.
- Light without Dots: The PC opal diffuser makes the light softer and gets rid of bright spots, making it even.
- Strong aluminum: It protects your LED strips by acting as a heat sink and makes them last longer.
- Simple to put together: Just screw it to the drywall, cover it with plaster, and then add the LED strips and diffuser.
How to Install Your Inside Corner LED Plaster Profile
- Use screws to firmly attach the aluminum channel to the inside corner of your drywall.
- Carefully plaster over the flanges, using joint compound to feather the edges so they blend in with the wall.
- Once the plaster is dry and clean, put your LED strip into the channel.
- Put the opal diffuser in position, making sure the light effect is perfect and dotless.
