Sealing a bathroom in 5 easy steps

Sealing a Kitchen

STEP 1: Choose the right bathroom caulk or sealant so you don’t have to do this again and again.

To stand up to the daily demands of a bathroom, select a 100% silicone or paintable silicone sealant for surfaces that are expected to be in contact with water. GE-branded silicone bathroom sealants never shrink or crack, creating a long-lasting, flexible, waterproof seal around showers, bathtubs, countertops and sinks. However, if the surface will only be exposed to periodic moisture or humidity, consider GE- branded siliconized acrylic latex caulks and sealants. These caulks and sealants are paintable, durable, and have strong adhesion.


STEP 2: Clean the surface.

Remove old caulk/sealant from your shower, bathtub, sink or countertop. Typically, it needs to be cut, scraped or chipped away from these areas using a utility knife, putty knife or painter’s multi-tool. To assure proper adhesion, remove soap scum and other residue from the surface to be sealed prior to application. Thoroughly rinse the area with soap/cleanser and wipe away excess water.
TIP: Wiping the joint with alcohol or window cleaner ensures no soapy residue is left behind.


STEP 3: Open the tube and seal.

Cut nozzle of your bathroom cartridge to the desired bead size. Pierce inner seal with seal punch found on most caulk guns. Insert cartridge into caulk gun. Squeeze with even, consistent pressure to control the rate the caulk/sealant leaves the tube.
TIP: Apply masking tape or painter’s tape to either side of a joint to create a straight edge before applying caulk to your bathtub, shower or countertops.


STEP 4: Smooth the seal.

Use a gloved finger or caulk-smoothing tool to smooth caulk/sealant into joint within two to five minutes.
TIP: If you applied masking tape in the previous step, remove immediately after smoothing the seal.


STEP 5: Clean up.

Before caulk cures, wipe away excess sealant on surface, hands and tools with a dry cloth.
