Wall Solid Sealants, What are wall solid sealants

Wall solid sealants speaks to what are wall soild sealants, why use wall solid sealants and types of wall solid sealants.

Sealant materials in addition to the gunnable sealants are used for sealing seams in building exterior walls.

Gaskets are strips of various fully cured elastomeric, which are rubberlike materials manufactured in several different configurations and sizes to be used for many varied and different purposes.

They are either compressed into a joint to seal lightly against the surfaces on either side or inserted in the joint loose and then expanded with a lock strip insert.

Preformed cellular tape sealant is a strip of polyurethane sponge material that has been impregnated with a mastic sealant. It is delivered to the construction site in an airtight wrapper, compressed to one fifth or one sixth of its original volume.

When a strip is unwrapped and inserted, it expands to fill the joint and the sealanr material cures with moisture from the air to form a watertight seal.

Preformed solid tape sealants are used only in lap joints, as in mounting glass in a metal frame or overlapping two thin sheets of metal at a cladding seam. They are thick, sticky ribbons of polybutene or polyisobutylene that adheres to both sides of the joint to seal and cushion the junction.

They are so sticky that they cannot be inserted into a joint, but must be applied to one side of the joint before it is assembled.

Other considerations

Brick walls are sturdy structures that are not only functional in weight support, but ruggedly aesthetic. Brick walls can be found inside a residential dwelling, separating two rooms or as an exterior facade. However, brick is porous and if not properly sealed, moisture seeps through the wall into the home. To prevent moisture, which can lead to mold and mildew growth, you'll have to seal the brick wall.


Perimeter sealants require maintenance to maximize service life. Perimeter sealants, properly designed and installed, have a typical service life of 10 to 15 years. Removal and replacement of perimeter sealants require meticulous surface preparation and proper detailing.

Aluminum frames are generally painted or anodized. Factory applied fluoropolymer thermoset coatings have good resistance to environmental degradation and require only periodic cleaning. Recoating with an air-dry fluoropolymer coating is possible but requires special surface preparation and is not as durable as the baked-on original coating.

Anodized aluminum frames cannot be "re-anodized" in place, but can be cleaned and protected by proprietary clear coatings to improve appearance and durability.

Exposed glazing seals and gaskets require inspection and maintenance to minimize water penetration, and to limit exposure of frame seals and insulating glass seals to wetting.
