How to Cut and Install Foam Ceiling Molding

In construction, ceiling molding is an alternative to ceiling overhangs. Ceiling molding is usually installed in office areas or basements. A home builder has a choice between pre-cut ceiling molding and custom molding. Custom molding can be cut into many pieces of different sizes. You can make the cuts large or small it’s all up to you. Ceiling molding is lightweight, therefore you do not need pulleys to lift it up during installation.

Foam molding can be installed at home without the help of a professional. Installing foam molding does not require many tools, except those for cutting the molding. With pre-cut foam molding, you only need glue to install it. Foam molding can be installed on straight walls as well as on internal and external corners. To estimate the amount of pieces you will need, just count the number of corners in your room. To estimate straight/linear molding for straight walls, measure the length of the walls. With these figures, you can proceed to make your order. Pre-cut molding is more expensive than custom molding, so cut your own molding to save costs. Follow the simple steps below to cut and install ceiling molding.

Materials and Tools

  • Sandpaper
  • Miter saw
  • Ceiling molding
  • Pencil
  • Ruler
  • Measuring tape
  • Adhesive for foam

Step 1 – Measure the Molding

Using a meter ruler, measure the required lengths of the ceiling molding.

Step 2 – Cut and Trace

Cut the required size of ceiling molding using a miter saw. Use this piece to trace the size of other pieces on the big ceiling molding you have. Put the piece on top of the big molding, then draw lines around to make an outline.

Step 3 – Cut the Outlines

Cut along the lines using a miter saw. While cutting the molding, you should hold it steadily with your other hand. Keep the saw straight to make a nice straight cut.

Step 4 – Smooth Sand the Sides

Use a sandpaper and smooth sand the sides of the molding pieces. Do not smooth sand too much or else the edges will be rounded. Rounded edges are not good because they make molding look smaller.

Step 5 – Apply Adhesive to Molding Pieces for Corners

Apply adhesive at the tops and backs of the molding pieces for corners. Spread the glue in a zigzag manner on the surface. Press each molding piece firmly onto the wall. Hold for about 35 seconds to allow the piece to stick onto the wall.

Step 6 – Measure Wall Length

Measure the distance between the ceiling corner pieces. Write down the measurements.

Step 8 - Cut Straight Molding

Straight molding is installed on the straight wall between the corner pieces. Make sure you cut the rights lengths that can fit the distance between the corners.

Step 4 – Apply Adhesive

Apply adhesive at the tops and backs of the straight molding.Spread the glue in a zigzag manner on the surface. Press each molding piece firmly onto the wall. Hold for about 35 seconds to allow the piece to stick onto the wall.
