Project Snapshot

Refreshing the caulk around your bathtub helps protect your bathroom from leaks and mold. Over time, bathroom caulk can crack, peel, or discolor, making the space look tired and leaving gaps for water to get through. This straightforward weekend project will leave your bathroom looking cleaner and improve its durability. All you need are some basic supplies and a little attention to detail. Handydads can walk you through every step, ensuring a durable, attractive finish.

Tools and Materials

To caulk your bathtub, gather a good quality caulk gun, a tube of mold and mildew-resistant bathroom caulk (silicone or siliconized latex works best), a razor scraper or utility knife, painter’s tape, a clean rag or sponge, and some rubbing alcohol. You’ll also want a caulk finishing tool or just a steady finger to smooth the bead. Make sure the area is clean, dry, and free of old caulk or debris before you start. Having a small bowl of soapy water nearby can help with cleanup. Ventilate the bathroom to speed up drying and to minimize lingering odors.

Step-by-Step Instructions

Start by using a utility knife or razor scraper to carefully remove any old caulk from around the tub edges. Clean the surface thoroughly with rubbing alcohol and let it dry completely. Apply strips of painter’s tape above and below the seam to keep the new caulk line crisp and even. Cut the tip of your caulk tube at a 45-degree angle and place it in the caulk gun, applying steady, even pressure as you run a bead of caulk along the seam. Smooth the bead with a caulk tool or your finger dipped in soapy water, then carefully remove the tape while the caulk is still wet, allowing it to cure according to the manufacturer’s directions before using the bath again.

From the Toolbox

Early in my handyman days, I helped a friend renovate a rental property. Rather than remove the old, cracked caulk around the tub, the previous tenants just added more on top. It looked messy and didn’t stop the leaks. We learned quickly that prep work is the real secret to success. Once we cleaned up the mess and took our time with masking, the new caulk looked professional and lasted for years. That job taught me that doing it right the first time saves plenty of hassle down the road.

Top 5 Mistakes

Skipping removal of old caulk leads to poor adhesion and leaks. Neglecting to clean and dry the surface before caulking invites mold. Cutting too large a hole in the caulk tube causes messy, thick lines that are hard to smooth. Not using painter’s tape results in uneven edges that look sloppy. Rushing the curing process by exposing caulk to water too soon will prematurely ruin your work.

Tool and Material Recommendations

A quality dripless caulk gun helps you control the flow and avoid fatigue. Choose a high-grade bathroom caulk designed for wet environments. For removal, a flexible razor scraper is more effective than a rigid one. Painter’s tape yields crisp lines and minimizes cleanup. Keep a dedicated caulking tool or disposable gloves handy for smoothing your bead effortlessly.

Quick Tips and Hacks

Warm up tubes of caulk to make them easier to squeeze and control. Always pull the caulk gun toward you for a smoother bead. Dip your finger or smoothing tool in soapy water before running it over the fresh caulk to prevent sticking. Remove painter's tape before the caulk skins over for a sharp finish. Store leftover caulk airtight so you can use it again for touch-ups.
