How to properly caulk baseboards for a seamless finish?

To properly caulk baseboards for a seamless finish, start by cleaning the area thoroughly and removing any old caulk. Cut the tip of the caulk tube at a 45-degree angle and apply a smooth, even bead of caulk along the baseboard joint. Use a damp cloth or finger to smooth out the caulk and remove any excess. Allow the caulk to dry completely before painting for a seamless finish.
