- Caulks and sealants’ use and locations are determined by cost-effectiveness standards and procedures. Factors include durability, paintability, adherence, color, toxicity, flammability, etc.
- Siliconized acrylics are usually used in interior locations or where paintability is important. For application in visible areas, the customer must approve the application, and see a sample before continuing. Clear acrylics, having a shiny appearance, must be used only where suitable, and should be approved by the customer for use in visible areas. Clear acrylics, due to having greater shrinkage, should be avoided.
- Pure silicone is applied for exterior applications unless paintability is desired. Pure silicone can be used for locations where sealants are required between wood and metal, wood and concrete, or other materials with differential expansion because of changes in moisture and temperature, or where you need greater flexibility.
- Caulking is applied on the interior of the home for general air leakage and to control the moisture entrance into wall cavities.
- Caulking is applied on the exterior of the home to stop moisture accumulation into the walls of the building and to seal areas of air leakage.
- When needed, windows will be caulked as per the full perimeter of the interior (or exterior), including sill area, side stops, apron, and casings.
- When needed, doors can be caulked along with the interior (or exterior) casings and door jambs/stops.
