​

Joint Tape is designed for use with ready mix or setting-type joint compounds and gypsum veneer plaster systems to conceal and reinforce joints of interior walls and ceilings.

 

ADVANTAGES

• Buffed on both sides for better bond.

• Center crease for ease of folding at corners.

• Easy to apply.

• High strength to resist distortions such as stretching, wrinkling and tearing.

 

DELIVERY AND STORAGE OF MATERIALS

All materials should be delivered in their original, unopened packages and stored off the ground, in an enclosed shelter and protected from weather. Damaged or deteriorated materials should be removed.

 

STACKING Joint Tape should not be stacked more than two pallets in height.

​

 

 

 

GENERAL
Installation of Joint Tape should be consistent with methods described in the noted references and standards and as indicated
on next page.

 

ENVIRONMENTAL CONDITIONS
In cold weather (outside temperature below 50°F [10°C]), temperatures within the building should be maintained at a minimum 50°F (10°C), both day and night, during joint finishing. Adequate ventilation should be provided to eliminate excess moisture.
Wet/damp conditions slow the drying process. Adequate drying time is essential to prevent unwanted conditions such as delayed shrinkage. Subsequently, 24 hours drying time between coats maynot be sufficient.

Apply a uniform layer of ready mix joint compound, approximately 4 in. wide over the joints of the drywall. Center Joint Tape over the joint and embed in the compound to ensure a proper bond. Using a broad knife or trowel, remove excess material leaving about 1/32 in. of compound under the tape and then apply a thin coat of compound over the tape.

 

Ceiling and wall angles are treated by folding the KosTech Joint Tape to fit the angles and embedding it in the compound. After the compound is thoroughly dry, apply a second coat of ready mix, feathering about 2 in. beyond the first coat of compound.

 

Continue this process until the desired finish is achieved.

 

All inside corners should be finished with at least one coat of ready mix joint compound with the edges feathered out.

 

All nail or screw head dimples and flanges of trim beads should receive two coats of ready mix joint compound. The second coat over the trims should be feathered out 9 in. on both sides.
