>>8070506>Caulk or caulking is a material used to seal joints or seams against leakage in various structures and piping.btw pic related caulk line is way too thick. But most of the time, caulking is done after applying tape to baseboards and areas where the painted wall meet woods.
The reason being is that the tape creates a nice and straight line for you to paint onto the base board, and the caulking acts as a seal to keep paint from getting under the tape.
