AFM Safecoat Dynoseal Roof Sealant is a sophisticated low-odor,
all-weather, waterproof, vapor-proof coating, and sealer remains flexible for years. This all around
sealer can be used on roofs as well as below grade foundations and even raised bed gardens. It is highly
resistant to flame spread and temperature change, and when cured is also highly resistant to gasoline,
oil, grease, fungi, acids, and alkalines.
USE ON:
Seamless roofs and as a deck coating and underlayment for shower stalls, pools, tubs and saunas. It
is recommended for use in repairing roofs, flashing, shingles, metal seams, and as a vapor barrier
against moisture from below-grade foundations and raised bed gardens.
LIMITATIONS:
Safecoat sealers are made without formaldehyde preservatives. Do not contaminate. Store in airtight
containers. Do not use in temperatures below 55 degrees F. Do not freeze. Thick application, high
humidity, or conditions other than normal will cause Safecoat to dry and cure more slowly.
SURFACE PREPARATION:
Clean surfaces of dirt, grease, mildew, and oil. The surface should be completely dry before
application.
APPLICATION:
Before application stir Safecoat DynoSeal, then apply with a brush or 3/8” roller. Roof and deck
coating: 2 coats. Below grade application: 4 coats.
Safecoat DynoSeal is not meant to be exposed to the elements for extended periods of time. It should
be top-coated with Safecoat RoofGuard. Note: these instructions are intended to be general only and
not exhaustive. The applicator should determine which preparation and techniques are best suited to
the specific surface.
CLEAN-UP:
Clean tools and equipment with a warm soapy water solution.
DRYING/CURING TIME:
Re-coatable after 2 hours in normal conditions. Normal conditions include a dry surface, access to
fresh air flow, moderate humidity, and temperatures above 55 degrees F. The temperature should
remain above 45 degrees F for two days to allow full curing. Surface remains tacky to the touch
after drying.
HEALTH PRECAUTIONS:
As with all natural sealers and coatings, keep the container tightly
closed and out of the reach of children. Do not take it internally. Keep from freezing. Always use
adequate ventilation.
