Caulk your windows and doors in 5 easy steps.

STEP 1: Choose the right caulk so you don't have to do this again and again.

Sealing windows and doors with caulk helps keep the harsh outdoor elements from coming in. But moisture, extreme temperatures and the sun's UV rays can cause acrylic caulk to lose its flexibility and degrade. Instead, choose a 100% silicone or paintable silicone caulk. GE-branded silicone caulks create a long-lasting, flexible, waterproof seal that never shrinks or cracks.

Acrylic caulks and so-called "silicone-tough" acrylics can harden, crack and crumble over time, so they may need to be replaced to prevent leaks, mold growth and energy loss. Think about it: If you can wash off caulk with a little soap and water, how long will it protect your home against the forces of nature?




STEP 2: Clean the surface.

Remove old caulk. Typically, it needs to be cut, scraped or chipped away. Use a utility knife, putty knife or painter's multi-tool. Thoroughly rinse the area with soap/cleanser and wipe off excess water. Remove soap scum, as caulk struggles to adhere to this residue.

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 to 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 leaves the tube.

TIP: Apply masking tape to either side of a joint to create a straight edge. Apply caulk.




STEP 4: Smooth the seal.

Use your finger or wet caulk-smoothing tool to smooth caulk 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.
