A cheap, paintable, easy-cleanup caulk that is the right pick for interior trim and gaps but not for constant water immersion.

Pros

  • Fully paintable within about 30 minutes with latex or oil-based paint, perfect for trim and molding
  • Easy water cleanup and smooth tooling make it very beginner-friendly
  • Inexpensive and widely available, so it is economical for whole-house sealing jobs

Cons

  • Only water-resistant, not fully waterproof, so it is a poor choice for constantly wet shower joints
  • Latex caulk shrinks slightly as it dries and may need a second bead on wide gaps
  • Less durable and shorter-lived than 100% silicone in high-moisture or exterior exposure
