How to Install Wood Bullnose Trim

Updated April 17, 2017

Many people want to improve the value of their homes by installing hardwood floors. The warm beauty and ease of care make hardwood floors desirable by owners and buyers. When installing your hardwood floor, use wood bullnose trim to bridge the height distance between your floating hardwood floor and your carpet, or to finish stair edges. Installation is quick and easy.

Measure the length and width of the area needing bullnose trim. Purchase bullnose trim matches your hardwood's colour in the correct width. Cut the trim to the correct length using a hand saw.

Apply subfloor adhesive to the back of the bullnose trim. Use a zigzag glue pattern. Keep the adhesive at least 1 inch inside the trim's edge.

Press the bullnose trim into place. Slide it into the groove of the adjacent piece of hardwood if using tongue-and-groove wood.

Nail the bullnose trim in place keeping the nails close to the curved edge. Place the nails about 6 inches apart. If you're not using tongue-and-groove wood, nail the trim along the edge opposite the curved side.

Wipe excess glue using a damp rag.

Apply wood putty to the dents left by the nails. Make sure the nails are completely covered. The putty should be level with the top of the hardwood. Use your finger to wipe off excess putty. The putty should blend in with the colour of the wood.

Allow the glue to dry completely (at least a few hours) before walking on the trim.
