Installing a bullnose form is an easy enhancement you can make to a stucco structure that will add additional architectural detail and appeal. Bullnose forms come in a variety of shapes and sizes, and are much more cost effective than other options. They can blend seamlessly into the existing exterior of the home or building, and can frequently be customized for your particular project. Forms can be cast and ready for deliver sometimes in as little as 24 hours. Here you will find basic how-to information on installation of the bullnose form.

Step 1: Prepare the Form

The form should be cut to the desired lengths and angles using the miter saw or miter box and handsaw. Make sure to measure carefully, particularly if the form is custom created. Work on one section at a time. Once the forms are ready for installation, clean off any dirt or debris that will interfere with adhesion.

Step 2: Install the Form

Apply adhesive with the trowel and use the notched side to create ridges in the adhesive, holding the trowel at a 45-degree angle to the form. Apply adhesive to the butt-ends of the form as well Apply the form to the desired area, pressing firmly and wiggling slightly back and forth to eliminate air pockets. Some forms may need additional support to maintain the proper position until the adhesive has set.  Position butt ends as tightly together as possible, and fill any gaps with styrofoam slivers.

Step 3: Cover Joints

Using the spackle knife, even out any adhesive that has oozed out between the butt-joints. Dip a paintbrush in water and shake off the excess water. With the damp paintbrush, even out any extra adhesive that has oozed out. Do not over do it to the point where it is pulling out of the joint, just blend as much as possible.

Step 4: Hard Coat

Let the form dry thoroughly and completely. Once it is completely dry, it is time to apply the hard coat. The hard coat adds additional durability and protection to the form. You will mix equal parts of A and B with a paintbrush. Be careful with the mixture, and if any comes in contact with skin wash it immediately. This is almost like an epoxy. Apply the hard coat to the form with a paintbrush. Mix small amounts at a time until you get a feel for how much you will need, and dispose of any leftover according to the package directions.

Step 5: Paint

The final step to to pain the form to match the rest of the exterior. This is easily accomplished if the forms are being installed in a new structure, just use the same exterior paint that is used on the rest of the project. If this is an addition to an existing structure, a local paint store can over a nearly perfect match if you don't have any of the original paint color.
