Caulking cracks is one of the first steps to a good paint job, right after cleaning the surface.

While many people, and unfortunately some painters, do not know how to use the different kinds of caulk, or how to properly apply caulk. The pictures show properly applied and improperly applied silicone corner joint…  this is caulking 101.

Improperly applied caulk

Properly applied caulk

Nothing drive me as crazy as when we get called out to paint a building where some well-meaning maintenance facility person has applied silicone all over the walls that need to be painted. You see, silicone is not paintable. There are many other types of caulk that work just as good or even better. These other types can also be painted.

Masonry control joints need a backer rod (foam cord) to hold the caulk in place so it can be applied. The caulk should be either a 1 or 2 part urethane caulk if it will need to be painted or a industrial silicone if painting will never be needed.  There are some new combinations of silicon /polyester resin that have the properties of silicone and can be painted…  look forward to seeing more of these.
