Where and How to Caulk Baseboard

At the top of the baseboard

Homeowners apply this on the top ridge of the baseboard where the board meets the wall. The caulk helps fill the gap where the baseboard does not contact the wall close enough. Using caulk on the top of the baseboard is usually purely cosmetic because covering the small gaps between the wall and the baseboard gives an admirable shine.

At the bottom of the baseboard

You need to apply this along the floor where the baseboard and the tiles join. As time passes, gaps start expanding under the baseboard. Caulking along the floor area prevents the baseboard from constantly getting wet from water.

Seal the entry points of insects

Insects such as ants, use open gaps and crevices along the baseboards as entry points. Caulking the cracks and holes are easy, cheap, and durable than using toxic sprays and powders to protect against home invasion by bugs. These sprays contain harmful chemicals that are bad for your children and pets. Where Caulking is a one-time investment and works way better than spending $1000 on repeated pest control. The unsealed spaces and crevices also provide shelter for insects within the house.

Most wood flexes and shifts position depending on temperature and moisture. Baseboards in the moist areas of your house will expand due to high humidity. Caulk is a flexible element that lets the wood to move freely without breaking the seal. Therefore I would suggest homeowners, caulk the top and bottom of the baseboards with the right caulk that will shrink and stretch according to the movements of the baseboard in different weather conditions.

Never mix different kinds of caulk

People often get misled by the idea of combining two different types of caulk to improve caulk’s properties. Rather than being more effective, the combination will just turn out faulty. Companies formulate each caulk to work on their own, they all have different properties that make them useful for different works. Combining the different caulks may produce a product that will not stick to the surface or offer any assurance of protection. I will always suggest my readers to use only one type of caulk.

Use a wet rag

Use a wet cloth and then your finger to wipe and smoothen the bead of the caulking. Always smoothen the caulk instantly. If you delay, the caulk will get lumpy and will be difficult to manipulate.
