Use hot-dip galvanized (HDG) fasteners per ASTM
A153 when attaching galvanized metal connectors.
Use fasteners per the manufacturer’s recommendation
when attaching the surface decking boards to the
supporting joists.
Use for all applications where the wood is subject to
wet conditions.
Apply in fair weather when the air, surface and
membrane are at temperatures of –4°C (25°F) or
higher. Install onto a clean surface. Remove dust and
dirt.
Surfaces shall have no damaged or unsupported areas.
Joints between wood members should not exceed ½
inch.
Using the 6 inch and 12 inch measurement markings,
cut the membrane to the desired length. Install the
membrane such that all laps shed water – the top
membrane layer should go over the bottom layer.
Stapling of the membrane is optional and can promote
adhesion.
To ensure corrosion protection, GCP Vycor Deck
Protector should completely separate the pressure-
treated wood from the galvanized metal connector.
Be careful not to damage the membrane during
application. If torn or damaged, the corrosion
protection performance of the system could be
negatively aected.
Due to the slight asphaltic odor, do not leave
the membrane exposed to interior living spaces.
Applications within wall/ceiling cavities may be
acceptable, if the membrane is trimmed around the
connector.
GCP Vycor Deck Protector may be incompatible with
certain solvents/caulking and high concentration of
resin and pitch. See our website for more information.
Do not use in hot desert areas of southwestern United
States.
Typical deck applications (such as on ledger boards/rim
joists or underneath joist hangers) may expose GCP
Vycor Deck Protector only to indirect sunlight (with
limited intensity) and only for short periods of the day,
if at all. Such UV exposure is acceptable. The product
should not be le permanently exposed to direct
sunlight. It is recommended that GCP Vycor Deck
Protector be covered within 30 days.
However, exposures of up to 60 days may be
acceptable when the membrane is used for corrosion
protection. It is recommended that the product be
trimmed around the connector to limit the direct UV
exposure (for instance, at post bases).
Exercise caution and follow the appropriate OSHA fall
protection guidelines when walking on membrane. Do
not install membrane on roof.
Insects cannot ingest, live or breathe in the membrane.
