The Tool Barn


Measure to edge of opening

Step 5:

Measure the opening for the new piece of molding.  If the molding goes around the threshold like this, make sure you measure from the bottom.


Mark distance

Step 6:

Transfer your measurement from the rule to the new piece of molding and, using a miter box, cut the new piece at a 45 degree angle. 


Mark length by holding in place

Step 7:

If your molding needs to be trimmed to fit at the bottom, now is the time to do it.  I like to fit the trim in place and transfer the necessary marks directly to the trim.


Seal ends with primer and paint

Step 8:

Using an exterior paint, paint the ends you just cut.  Also paint all of the other sides except the face.  Most of this molding comes pre-primed from the factory but it still needs a final coat to protect it.


Nail molding in place 

Step 9:

Nail the new piece in place.  Use finishing nails.  I generally use 2" 8 or 10 penny nails.  You should use larger nails if there is anything affixed to the brick mold (like a storm door). 


Set the nail head below surface

Step 10:

After the nails have been driven, set the nails by driving them below the surface of the molding. 


Filled nail hole

Step 11:

Using an exterior-grade filler, fill the nail holes.  If you do not do this, the nails will rust and leave stains on the paint. 


Final painting

Step 12:

Paint the face of the molding with the same paint you used above. After the paint has dried, replace the caulk that you cut out in step 1.  Keep in mind that if you are using silicone caulk that you should mask off the area you are going to caulk to avoid getting it everywhere.  Also, most silicone caulks are not paintable.
