If you are building a custom home and have decided you want to install some extruded stucco trim on its exterior surface to give it a more finished look, then the below tips will help you effectively do so.

Understand How Extruded Stucco Trim is Manufactured 

Since stucco alone isn't strong enough to be extruded to create trim pieces that won't fall apart, it has to be mixed with a plastic polymer before being pushed through shaped extruding molds. The plastic polymers are not visible, so each trim piece will look identical to the stucco finish on your home.

The plastic polymers in extruded trim pieces ensure they are durable, easy to install, and can withstand the elements year after year.

Wait Until the Stucco Finish Is Completely Dry Before Installing the Trim Pieces

The stucco on your new home needs time to dry and cure before you can safely install any trim pieces. If you attempt to install the trim before the stucco has fully cured, then you run the risk that it will chip or sluff off as you work. Since repairing stucco can be expensive and will require even more drying and curing time, it is advised you wait until it is solidly in place before installing any trim.

Use a Cement-Based Poly-Bonding Adhesive to Attach the Extruded Trim Pieces

Since both the stucco on your home and in the trim pieces can crack or break if you drill into them, you need to install each trim piece using a cement-based poly-bonding adhesive. This type of adhesive comes in a bag similar to a bag of cement and will need to be mixed with water in accordance with the instructions on the package. 

Using a trowel, place small mounds of adhesive all along the trim pieces and then push them into place. The adhesive will hold them in place.

Choose Trim Pieces With Mitered Edges to Make the Process a Lot Easier

Finally, it is important to note that you should order your extruded trim pieces precut with mitered edges. This will allow you to more easily slot them together as you install them around each window and door. If you purchase trim that isn't pre-mitered, then you will need to custom cut each piece with a special saw blade, and the project will take a lot longer.
