Why Does Caulking Fail

different caulking products

  1. The wrong type or low-quality type of caulk, for example, using latex or vinyl caulk in a bathroom or around/near a kitchen sink would cause caulking failure. In this instance, you should use a silicone based caulk
  2. Not prepping the surface area before the caulk application to prepare it for painting
  3. Applying a thin bead of caulk would not be sufficient to do the job properly.

Caulking Success

  1. Choose the appropriate caulk type for the job/surface
  2. Follow the directions/instructions. You could ask any of the experts at one of your local hardware type big box stores, an expert at any Benjamin Moore Store or a professional House Painter
  3. Use good quality caulk for your home improvement project. This will ensure it is the correct one to use on wood, ceramic tile, concrete, glass, brick even in some instances where moisture is apparent or unavoidable.
  4. Prepare your surface properly before applying any caulking. This requires you to clean the surface, remove any old caulking that has either cracked, peeled or become old. ensure all peeling paint is also removed before any other caulking is applied.
  5. To give the caulk and paint a good bonding you should most often give it a primer. This way the paint adheres properly to the fresh new caulking. Priming it will also avoid it from improper drying and poor performance after paint is applied.
