split caulk


Why is splitting caulk a concern?

Other than being aesthetically unsightly, split caulk leaves gaps for water and air to get in, which may lead to higher energy bills, mold, or water damage.


What causes split caulk?

Changing weather conditions that create inconsistent humidity can affect the flexibility of caulk but the most common cause of split caulk is using the wrong caulk formula. Acrylic caulk is more prone to crack or split over time, so it is best to use a flexible, 100% silicone caulk for areas that are prone to splitting such as the bathroom or kitchen. If paintability is an issue, use a siliconized acrylic caulk to get the best of both worlds.



The Red Devil DuraGuard™ Kitchen & Bath Siliconized Acrylic Caulk is a great choice.
