Cutting and Fitting

Clean cuts and accurate miters are what make mouldings look “built-in.”

Recommended cutting tools

• Miter saw with a dry diamond blade
• Hand saw + miter box (good for smaller jobs)
• Utility knife (for light trimming or small adjustments)
• Sanding block / fine sandpaper (for tuning edges)

Use dust control and PPE when cutting and sanding.

Tips for clean cuts

• Support the moulding fully so it doesn’t flex while cutting.
• Make controlled cuts. Don’t force the blade.
• If the cut edge is slightly rough, lightly sand to true the edge.
• For long profiles, keep your cut square and your miter angles consistent.

Corners and returns

• Outside corners: typically mitered; dry-fit to confirm tightness.
• Inside corners: can be mitered; dry-fit and fine-tune with sanding if needed.
• Returns/end caps: if your design requires a “return” back to the wall, plan and cut these pieces early so the end finish looks intentional.

If you’re not sure about your corner conditions (non-square corners are common), dry-fit first and adjust your cuts accordingly.

Dry-fit before basecoat

Always dry-fit each piece in place before installing permanently. Confirm:

• Alignment to your reference lines
• Corner tightness
• Straightness over long runs
• Seam locations look acceptable
