How to Seal Your Molding, Trim and Baseboards in 5 Steps

Sealing a Kitchen

STEP 1: Use the right caulk before you paint molding and trim for beautiful results.

For a lasting finish around molding, baseboards and trim, apply a paintable silicone sealant or a siliconized acrylic latex caulk/sealant before you paint. GE-branded paintable silicone sealants are waterproof and create a flexible, paintable bead that never shrinks or cracks. Also consider siliconized acrylic latex caulks or sealants, as they are paintable, durable and have strong adhesion for lasting results.


STEP 2: Open the tube and seal.

Cut nozzle of your 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 in order to control the rate the caulk/sealant that is dispensed from the cartridge.
TIP: Apply masking tape to either side of a joint to create a straight edge before applying caulk to your molding, trim or baseboards.


STEP 3: Fill edges and gaps.

Apply caulk/sealant along the edges and joints of your molding, trim or baseboards.

TIP: Seal molding and trim from top to bottom. Start by laying a bead on the top edge of your molding, then work your way down to avoid smudging your fresh caulk/sealant.



STEP 4: Smooth the seal.

Use a gloved finger or 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 the caulk/sealant around your molding, trim or baseboards cures, wipe away excess from surface and tools with a dry cloth.
