Full Product Manual

• Easy installation—single component that can be easily spray-
applied or roller-applied with standard equipment . Requires no
mechanical fasteners.
• Fully adhered—strong adhesion to OSB and plywood. Unlike
housewrap, will not tear away in the wind and expose house to
weather damage
• Seamless—uid applied membrane creates a monolithic
coating without laps
• Damp surface tolerant—can be applied to damp-to-touch
surfaces
• Versatile—easy to use at details such as internal and external
corners, brick ties, penetrations, etc.
• Low odor and VOC Content
• UV resistant—can be exposed for up to
4 months before cladding installed
• System solution—excellent weatherization system when
combined with compatible Vycor ashing products
Principal Applications

Installation
Safety
Refer to product label and Material Safety Data Sheet before use.
All users should acquaint themselves with this information prior
to working with the material. Carefully read detailed precaution
statements on the product labels and MSDS before use.
MSDSs can be obtained from our web site at graceconstruction.

Surface Preparation
All surfaces must be sound and free from loose nails or screws,
sharp protrusions or other matter that will hinder the adhesion or
regularity of the membrane installation. The surface must also
be free from frost, dirt, grease, oil or other contaminants. Clean
loose dust and dirt from the surface by brushing or wiping with a
clean, dry cloth. Refer to
Technical Letter 3, Application Instructions for Oriented Strand
Board (OSB) and Plywood for further information.
Exterior Sheathing Panels
Vycor enV may be applied directly to exterior sheathing panels
such as plywood and oriented strand board (OSB). To avoid
deection at the panel joints, fasten corners and edges with
appropriate fasteners. Fasteners should be driven ush with the
panel surface (not counter sunk) and into the framing system
in accordance with the panel manufacturers recommendations.
Joints and holes greater than
1
⁄
4
in. (6 mm) should be lled with
mastic or caulk, allowing sufcient time for the caulk to fully
cure before application of the tape and Vycor enV. Spray 8 mil
thickness of Vycor enV at the joints and embed in 4
1
⁄
2
in. (114
mm) wide Vycor enV Joint Tape.
Detailing
Detailing should be completed prior to applying the full coverage
of Vycor enV. The eld application should completely cover the
detail areas to provide a continuous membrane.
