How to Caulk a Staircase
- May 23, 2018 -

The use of caulk on a staircase provides a seal between the staircase and the wall and any gaps that may occur between the boards or joints of a hardwood staircase. The gaps are a dirt catcher and may be visually displeasing. The caulking process is fairly easy and requires the use of a water-based silicone caulk (acrylic silicone/acrylic sealant/silicone/sealant/adhesive/potting sealant/potting adhesive/potting compound/UV glue/flange sealant/conductive sealant/electrical sealant/electronic adhesive/epoxy sealant/epoxy adhesive) . It may be advantageous to use a silicone caulk that may be painted when caulking between the edge of the stairs and the wall but is not necessary.


Clean the gaps of the staircase to remove any debris. Sweep the area if possible. Vacuum all gaps to remove as much debris as possible.


2

Insert the silicone caulk in the caulking gun.


3

Cut the tip from the silicone caulk (acrylic silicone/acrylic sealant/silicone/sealant/adhesive/potting sealant/potting adhesive/potting compound/UV glue/flange sealant/conductive sealant/electrical sealant/electronic adhesive/epoxy sealant/epoxy adhesive) tube at a 45-degree angle with a carpenter's knife.


4

Squeeze the trigger on the caulking gun until a small amount of caulk is extruded from the end. Wipe the tip of the caulk tube to clean.


5

Position the tip of the silicone caulk at one end of a gap. The caulking gun will sit at a 45-degree angle to the gap.


6

Squeeze the trigger on the caulking gun while moving along the gap at a slow and consistent speed. Extrude a line of caulk into the gap. Stop squeezing the trigger and remove the tip of the silicone caulk at the end of the gap.


7

Fill each gap in the same manner.


8

Wipe excess caulk from the surrounding area with a damp cloth or sponge after each gap is filled.
