Exterior Crown Molding Installation
Exterior crown molding is an easy way to add an elegant and custom look to any home. Exterior molding is made from a different base material than the interior varieties. Depending on the type of exterior molding you choose, the installation process can vary.
One of the most inexpensive and easiest forms of exterior molding to install is polyurethane molding. Polyurethane is available in a variety of colors and styles, and looks just like wood. It will withstand harsh elements and humidity and last much longer than standard wood molding will.
Installing polyurethane molding requires a little work and some tools. You will need to install the crown molding with a special polyurethane adhesive, as well as use pin nails and silicone caulk. You will start by using the adhesive and placing the corner pieces. From there you will nail it in for added security. You can then move on the lengths of molding, following the same process. Paint the molding after it's been installed if you wish.
Fiberglass crown molding is popular for structures that have rounded or otherwise difficult to work with corners and shapes. Fiberglass can be bent to fit any shape. It is more expensive to use, but is also one of the easiest to install. Many varieties can be installed without any tools or fixatives. If the type you choose isn't this simple, you can generally install fiberglass with a simple adhesive. Rarely are nails, screws, or other hardware required. Fiberglass molding can be purchased at most lumber yards or home improvement stores.
Treated Wood Molding
Treated wood can be used as an exterior crown molding. This is very inexpensive, but purchasing the necessary materials to treat, weatherproof, and install the wood can add up. For those who want to stick with traditional designs, and don't mind adding extra effort and money in to the process, wood can be an excellent choice.
Wood molding will need to be treated with a high quality weatherproof material after it's been painted or stained. This will increase the overall life of the molding. Treated crown molding is installed using a wood adhesive, putty, and finishing nails. The holes left from the nails can be covered using the putty, and sanded to match the original surface.
GRFC, or glass fiber reinforced concrete, is a common material for exterior crown molding. This type of molding resists cracking, insect damage, rot, and is simple to install. The material is easily found in any hardware or home improvement store, and is relatively inexpensive when you compare it to the upkeep of other types of molding.
GRFC molding is installed in a similar fashion to fiberglass molding. A simple adhesive is used after the pieces are measured and cut. Rarely are lots of tools or nails needed to install GRFC molding.
Exterior crown molding is a great way to add a new look to the outside of your home with very little effort. Consider the amount of money you are able to spend, the amount of time you have available to finish the project, and the amount of upkeep you are wanting, and you can find the perfect exterior molding.
