A Bullnose finish is often added to wood stair treads to enhance the aesthetics and elegance of a staircase. Moreover, it reduces the risk of injury when someone is climbing up the stairs. Adding a bullnose to wood stair treads is a fairly simple task and can be undertaken with the use of a few simple tools. The following sections will explain exactly how to bullnose wood stair treads.

Tips and Warnings

Before starting out, please bear in mind several important safety precautions. First, always keep a pair of rubber gloves on hand that will protect you from any needless injuries. Moreover, make sure eye protection is worn during this project whenever you are using items such as a router, and a sander. It must also be kept in that adding a bullnose to stairs that have already been installed is a slightly tricky task and might require a considerable amount of time.

Anchor Wood

Now using the clamps, attach the piece of wood with the stair treads. Tightly clamp the wood and make sure it does not come loose.

Carve Out Wood with Router

Next, install the half-round bit which should be readily available from a hardware store. However, do ensure that the half-round bit is approximately half the thickness of the wood being used. Start carving out the wood using the router however please be careful when undergoing this step as the router can prove to be dangerous if not used properly. Carve out the wood into a moon shape with the router. Now that one side has been cut, turn the wood around and start cutting the same moon shape with the router on the opposite side. Clamp it onto the wooden stair treads tightly.

Sand the Bullnose

Now that the bullnose has been carved out from the wood, the next step is to sand it before it is painted. Use diamond sandpaper and start sanding it gently. Make sure that the surface of the bullnose is smooth before moving onto the next step.

Apply Primer

Now that the sanding is complete, add a coat of primer onto the bullnose part of the stairs. Wait for the first layer to dry before putting on another coat. To ensure a smooth layer has been applied, a roller can be used instead of a paintbrush as well. Apply 2-3 coats.

Apply Paint

Once the primer has dried use a paintbrush to paint the bullnose. Two or three coats should be applied to ensure the paint is applied properly. By this point, your bullnose shall have been added to the wood stair treads, and should even match the interior of your house because of the paint applied. When the paint has dried, you can clean up the work area and enjoy your new finish.
