Exterior Sealants

What’s most important when choosing an exterior architectural sealant?  We think you’ll agree that for any project, the following are of utmost importance:

  • Protection from the elements
  • Movement capability
  • Adhesion
  • Aesthetics


To meet the challenge of these criteria, Pecora has worked to become the leader in the industry by providing value added products that have become standards in sealant and weatherproofing solutions.

Interior Sealants

Interior sealants are important in filling cracks and gaps in trim and walls but can also include additional benefits such as containing smoke during a fire, reducing sound transimission and reducing the possiblity of bacterial growth in bathrooms and kitchen areas. Pecora’s breadth of interior products addresses these interior concerns:
