If you are going to be sealing cracks in the walls of your home, you need to make sure that you choose the right type of caulking in order to ensure that you keep water out and that you don't have to redo this process multiple times. Here are some tips for making sure that you choose the right caulking that will allow you to perfectly seal the cracks, as well as make sure that the process goes as smoothly as possible.
1. Opt for Mildew Resistant Caulking for Exterior Walls
When sealing a crack on the exterior of your home, make sure that you choose a caulking that is resistant to mildew. Some caulking is not resistant and will therefore allow mildew into your building and be damaged by any mildew that should invade. The results of this happening mean that you have to spend time and money drying out whatever area the wall was supposed to be protecting, as well as replace the caulking that you added in its entirety.
2. Choose Caulking That Provides a Paintable Surface for Interior Walls
If you are repairing a crack in an interior wall, you will need to be sure that you choose a caulking that has a texture that can easily be painted over. This means that you will need a caulking that, when applied in its entirety and dried, the caulking should not have a shiny surface. It should be dull and slightly textured to allow any paint that you apply to adhere better.
3. Don't Cut the Tube with a Horizontal Cut
Once you have chosen your tube of caulk, try to cut it at an angle. If you want to be able to apply very fine lines of caulk for smaller cracks, cut it at a steep angle. If you would rather get a lot of caulk out on the crack but still have some control over it, cut a shallower angle. If you make a simple horizontal cut on the tube, you won't be able to have anything to guide your application of the caulk.
4. Opt for Foam
If you have any incredibly huge cracks, opt for foam rather than caulk in order to make absolutely sure that you are able to get every nook and cranny. The foam should expand to fill the space perfectly.
