Why Should I Seal My Baseboards, Molding & Trim?

Sealing a Kitchen

Depending on your home’s age and condition, location within the home, and other potential factors, repairs and/or upgrades or other services may be necessary prior to the beginning and/or completion of your project that may involve the services of a home improvement professional.

Sealing your baseboards, molding and trim with a high-quality sealant can make all the difference. They’re features that make your home’s interior look even more beautiful and finished. While these projects might not be at the top of your list when it comes to sealing, here’s a few reasons why they should be.
 
SEAL IN THE BEAUTY WITH THE BEST
You should seal your baseboards, molding and trim with a paintable sealant for two main reasons. First, this can greatly enhance a room’s visual appeal by sealing unsightly gaps and cracks. Without the benefits of this type of sealant, enhancing the attractiveness of these elements can be significantly hindered. Second, and perhaps more importantly, using a high-quality, paintable sealant can create a mold and mildew resistant barrier against water intrusion.

For example, sealing molding in your dining room, living room or hallway may benefit the most by using  GE Max Shield Painter’s Advanced Polymer Acrylic Latex sealant. Its best-in-class3, paintable formulation is excellent for paint projects that need permanent flexibility, excellent adhesion, and durability to withstand the natural expansion and contraction of your home. And, although this kind of project isn’t normally at risk of water exposure, Max Shield Painter’s sealant is 100% waterproof for the ultimate protection.

But what if your project is regularly exposed to moisture, such as with baseboards that border your floors in your kitchen or bathroom? GE Max Shield Ultra Seal Advanced Polymer Acrylic Latex sealant is a high-performance, paintable sealant that can provide a 100% waterproof seal. Not to mention, this durable seal is permanently flexible.

As another example, you might need to seal trim around your windows and doors to help keep the outside air from infiltrating your home. In that case, GE Max Shield All Weather Advanced Polymer Acrylic Latex sealant would be an exceptional choice that offers a high-quality, paintable seal that is not only permanently flexible and durable, but also 100% weatherproof, allowing it to hold up to even the harshest weather conditions.  
 
GET THE JOB DONE RIGHT
With this knowledge in mind, you can approach your project with a newfound confidence. Here are our 4 key steps to successfully sealing your baseboards, molding or trim:
 
STEP 1: 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 that the sealant 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 baseboards, molding or trim.
 
STEP 2: FILL EDGES AND GAPS
Apply sealant along the edges and joints of your baseboards, molding or trim.
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 sealant.

STEP 3: SMOOTH THE SEAL
Use a gloved finger or caulk-smoothing tool to smooth sealant into joint within two to five minutes of application.
TIP: If you applied masking tape in the previous step, remove immediately after smoothing the seal.

STEP 4: CLEAN UP
Before the sealant around your area cures, wipe away excess from surface and tool with a damp cloth.
