Cracking Caulk on Stairs? Fix It in 3 Steps
Cracking caulk on stairs is often due to movement or incorrect application. To fix it, you'll need a caulk removal tool, new caulk, and a caulk gun. Start by removing old caulk, cleaning the area, and reapplying caulk suitable for high-traffic areas like stairs.
Tools and Materials You'll Need
You'll need a few specific tools and materials to fix the caulking on your stairs.
These include a caulk removal tool, a new tube of caulk suitable for high-traffic areas, and a caulk gun.
Having the right tools ensures a smooth process.

Remove Old Caulk
The first step is to remove the old, cracked caulk.
Use a caulk removal tool to gently pry out the old caulk without damaging the surrounding surfaces.
Be patient; this step is crucial for a clean application.
Prepare and Apply New Caulk
After removing the old caulk, clean the area thoroughly to remove any residue.
Then, cut the nozzle of your new caulk tube at an angle to achieve a smooth bead.
Apply the caulk in a continuous bead, ensuring it fills the gap completely.
Use a damp finger or tool to smooth out the bead for a professional finish.

The Practitioner's Reality Check
The Counter-Intuitive Insight: Most people assume caulking failure is due to poor quality caulk.
However, in my experience, it's often a result of improper surface preparation or incompatible materials.
The Common Trap: Don't fall into the trap of using any caulk for the job.
Ensure you choose a caulk that's specifically designed for high-traffic areas like stairs.
