FAQs

What thickness of window board does this joint fit?

This corner joint is designed specifically for 23mm thick window boards.

Can this joint be used for external corners?

No, this product is exclusively for 90° *internal* corners. Truly PVC Supplies offers separate products for external corners.

What other colors are available?

This specific product is white. Other color options such as Chocolate Brown and Caramel are available for 23mm window boards and compatible joints from Truly PVC Supplies.

How do I clean the corner joint?

Clean the joint using a soft, damp cloth. Mild detergent can be used for tougher marks, but avoid abrasive cleaners.

Do I need to glue the joint in place?

While the joint provides a mechanical fit, for a permanent and secure installation, it is recommended to use a suitable PVC adhesive or sealant.

Can I paint over this white corner joint?

PVC is generally not designed for painting. While it might be possible with specific primers and paints, it is not recommended and may void any warranty or affect the finish.

What tools are needed for installation?

You will need tools to cut the window boards and potentially trim the joint, such as a fine-tooth saw or a sharp utility knife. A tape measure and pencil are also useful.

Troubleshooting

Joint does not fit snugly

Ensure you are using 23mm thick window boards. Check if the window boards are clean and free from debris. The joint itself may need slight trimming for a perfect fit.

Visible gap at the corner

Verify the window boards are cut at precise 90° angles. If not, the joint may not sit flush. Consider using a suitable PVC adhesive to fill minor imperfections and secure the joint.

Joint is difficult to cut cleanly

Use a fine-tooth saw or a sharp utility knife. Make multiple shallow passes rather than one deep cut. Ensure the joint is securely held while cutting.

White color does not match existing boards

This variant is specifically white. If a different color is needed, please refer to other available color options (e.g., Chocolate Brown, Caramel) from Truly PVC Supplies.
