Coverage

VaproBond is available in 20 fl oz (592 g/ml) sausages

Sealant	Flashing
¼” (6 mm) bead will adhere 125 ft. (38 m) of overlapping membrane	30-45 wet mils (0.76 – 1.14 mm) covers 6-8 ft² (0.56-0.74 m²) Not recommended for wood applications.

Equipment

Apply using a professional caulking gun.
Use a DRY joint knife, trowel, or spatula to spread.
Do not use soapy water or alcohol when tooling or spreading.

Storage

Store VaproBond unopened sausages at temperatures lower than 80 °F (27 °C).
Do not open sausage until preparation work has been completed.
Do not alter or mix with other chemicals.
When stored at or below 80 °F (27 °C) VaproBond has a shelf life of 12 months after the date of manufacture.
Do not double stack pallets.
Dispose of unused product and container in accordance with local, state and federal regulations.

Cleanup

Immediately remove all excess VaproBond in undesired areas with mineral spirits.
Clean tools and equipment with mineral spirits or similar solvent immediately after use.
Observe all manufacture’s safety precautions.
Remove cured VaproBond using a sharp-edged tool.

Best Practice Installation Rough Opening Sequence for VaproBond


1. Install WrapFlashing SA SelfAdhered (orange) or RevealFlashing SA (black) into sill with 2.75” (70 mm) folded into Rough Opening (R.O.) 9” (229 mm) left on face, with bottom 6” (152 mm) of release film to remain	2. Install jamb pieces with 2.75” (70 mm) folded into R.O. 9” (229 mm) to be left on face.

3. Install head piece with 2.75” (70 mm) folded into R.O. 9” (229 mm) to be left on face. Roll all WrapFlashing SA (orange) or RevealFlashing SA (black) sections with weighted roller to ensure full contact.	4. Using the sausage gun, apply VaproBond in a zigzag pattern on the wall face surrounding the rough opening.

5. Immediately spread the applied material with a putty knife creating a 1” (25 mm) border around the rough opening.	6. Apply additional VaproBond in zigzag pattern on all inner surfaces of the rough opening.

7. Immediately spread until all surfaces are completely covered and substrate below is no longer visible (approximately 30-45 wet mils (0.76- 1.14mm).	8. Allow VaproBond to set, then inspect for voids and apply additional VaproBond as needed to achieve complete coverage. RO is now ready for window and head flashing installation (by others).
*Roll all WrapFlashing SA (orange) sections with weighted roller to ensure full contact.

Sealant Between Membrane


Overlap vertical seams by 12” (305 mm) minimum. Apply VaproBond adhesive sealant bead just below Integrated Tape line at the vertical seam joint.	Use hand roller to seal the seam for an air and water tight seal.

Tear and Abrasion Repair


Typical installation tears or abrasions	Remove excess membrane from tear until smooth with substrate

Cut and apply a patch of self-adhered field membrane or WrapFlashing SA Self-Adhered	Remove release film, smooth over with hand pressure	Use hand roller to ensure complete adhesion


Hole Patch Repair: seal the reverse lap (at top) with VaproBond to ensure a water and air tight seal	Abrasion Repair: apply VaproBond over abrasion and tool with a DRY joint knife, trowel or spatula

Reverse Lap Sealant

VAPROSHIELD BEST PRACTICE IS TO AVOID REVERSE LAPS BY PROPERLY SHINGLING MEMBRANE AND ROUGH OPENING FLASHING.


Apply 3/8” (9.5mm) minimum bead line of VaproBond to the reverse lapped membrane.	Use a DRY joint knife or trowel to tool VaproBond to shed water.
