Do you have to smooth out caulk?

You can actually smooth caulking down easily with your finger, running it in a long line along the bead. This can take some practice since you have to keep an even pressure and try to run along the entire length without stopping, if possible. It can take two or three tries to achieve real smoothness.

Can I use silicone caulk on wood?

Silicone caulk is excellent at water sealing and flexibility so it has its place in construction. There are two main places it never should be installed, wood or any painted surface. If paint will ever be applied to an area, then silicone does not belong there, ever, in any way.

How do you remove bad caulking from a job?

If the caulk was recently applied and is nonacrylic, you may be able to soften it with just water-soaked rags. Caulk that contains acrylic can sometimes be softened with isopropyl alcohol. But be careful when using it, as it's flammable. Once the caulk is removed, you can re-caulk and get professional results.

Can I use caulk instead of wood filler?

Caulk is great for. On the other hand, caulk is terrible for filling nail holes and other holes in wood because over time it will shrink and cause a divot. And wood filler is a terrible choice for filling gaps in trim – it would take forever to apply and sand.
