A Common Dry Glazing Issue:

The most common problems with a window assembly or skylight assembly that can result in rain leaks are:

  • Deteriorated or shrinked rubber gaskets: A component of many window assemblies include black rubber gaskets made of EPDM rubber. Overtime, these rubber gaskets crack and shrink creating holes where rainwater can seep in, resulting in leaks. The shrinkage and cracking most often happen at the outer and thinner edges of the gasket. The purpose of wet sealing is to completely conceal the gasket with the new silicone sealant to prevent leaking.
  • Missing or faulty sealant on window joints or fasteners: In some cases, window installation companies forget to put sealant on joints to prevent water infiltration. Also, sealants are prone to crack and deteriorate overtime. Thus, it’s a good practice to inspect and replace faulty sealants every 2-5 years depending on environmental conditions including sun light & UV exposure, temperature deformation, salt and air pollution.
  • Improper design or installation: Since rainfall in California is seasonal, amateur glazing companies don’t have sufficient expertise in waterproofing or put a strong emphasis on it. The most common installation issues are wrong location or setup of weep holes, missing end dams, exposed covers or frame joints that are not utilized as a weep system. In addition to, missing sealant on frame-to-wall joints.

Why Sealants Fail:

The #1 reason sealants fail or don’t last as long as they should is due to improper sealant application or deficient preparation by a contractor. An experienced wet sealing contractor knows how to select the appropriate sealant that is compatible with its bonding substrate.

Three Basic Types of Sealant Failure:

Loss of Adhesive: there is a break along the bonded line where the sealant connects with the substrate. The failure is due to the sealant not adhering to the substrate. Several reasons for loss of adhesive include joint movement exceeding the sealant capability, improper surface preparation, or improper bead configuration.

Cohesive Failure:  there is a split or tear in the actual sealant. The failure is due to the sealant not holding together. Several reasons for cohesive failure include improper sealant selection, poor mixing of multi-component sealants, possible air entrapment in the sealant from mixing, or improper bead configuration.

Substrate Failure: there is a break in the substrate not the sealant itself. The reason is due to poor surface preparation. The substrate had existing issues such as loose pieces of surface material and should have been cut back or sanded.

Properties of Silicone Sealants:

There are several advantages and disadvantages with silicone sealants. 

Advantages:

  • The ability to repel water and form watertight seals
  • UV stability & temperature resistance
  • Greater movement capability & elasticity
  • Adhesion to many substrates 
  • Ideal for bonding glass to metal

Disadvantages:

  • Attracts dirt
  • Potential for staining
  • Cannot be painted
  • A limited expiration date or shelf life for when the sealant should be applied

Our Process for Wet Sealing Windows:

5-step wet sealing process: Complete Removal, Cleaning, Surface Preparation, Application, Tooling.

  1. Silicone does not adhere to polyurethane sealants so it is crucial to fully remove old sealants. Silicone only adheres to silicone.
  2. Cleaning using the two-cloth method, meaning a solvent wipe followed by a dry clean wipe. To prevent adhesion failure, all dust, grease, or any loose pieces or contaminants need to be removed.
  3. Preparing the surface with bond-breaking tape or backers rod is necessary to create two-sided adhesion and maximize joint movement capacity. Otherwise there will be three-sided adhesion which limits joint movement and makes cracks happen.
  4. Applying sealant via application gun with a nozzle to match the width of a joint.
  5. Tooling is the last step usually neglected by amateur exterior caulking contractors. With the use of a special spatula, the recommended hourglass shape is formed for best adhesion and aesthetics.

Exterior Wall Caulking:

Exterior Wall Caulking is the procedure of sealing cracks in wall joints to block water intrusion while withstanding building vibrations that occur due to seismic movements & temperature deformation.

Window Caulking:

Window Caulking is a protective and waterproofing procedure to protect the building envelope. The process includes sealing window joints with an appropriate sealant to prevent water intrusion from entering the interior.
