M-1 Data Sheet
Application Guidelines:
Concrete
Prior to application remove any residual contamination
by mechanical abrasion, sand blasting or power washing.
On green concrete, remove all release agents, friable
and loose concrete. Dry all visible and standing water
prior to applying M-1
®
. Install an appropriate backer rod
to avoid three-point bonding.
Metal
Prepare all metal to ensure maximum adhesion. Remove
all rust, scale and residue by wire brushing to a bright
metal sheen. Remove lms, loose or inappropriate
coatings and oils with an appropriate solvent such as
alcohol.*
*CHEM LINK recommends that coated substrates be
tested for adhesion prior to starting a project. Please
contact Technical Services for specic application
guidelines and recommendations.
Wood
Wood should be clean, sound and dry prior to sealant
application. Allow treated wood to weather for six months
prior to application. Remove all coatings and paint (or
test for compatibility) to ensure proper bonding. Do not
use on re retardant lumber.
Priming
In most instances M-1
®
will not require a primer.
However, certain applications or substrates may require
a primer to ensure a long lasting bond and weatherproof
seal. It is the applicator’s responsibility to determine the
need for a primer. CHEM LINK recommends a primer be
used for any application where prolonged immersion is
anticipated.
Clean-Up
Wet sealant can be removed using a solvent such as
alcohol. Cured M-1
®
can be removed by abrading or
scraping the substrate.
Storage
Store original, unopened containers in a cool, dry area.
Protect unopened containers from water, heat and direct
sunlight. Elevated temperatures will reduce shelf life.
M-1
®
will not freeze.
Twelve months from date of manufacture when stored at
70°F / 21°C with 50% relative humidity. High temperature
and high relative humidity may signicantly reduce shelf
life.
Pails have a shelf life of six months.
Application Instructions
Remove all dirt, oil, loose paint, frost and other
contamination from all working surfaces with alcohol DO
NOT USE petroleum solvents such as mineral spirits
or xylene. Maintain M-1
®
at room temperature before
applying to ensure easy gunning and tooling. Test and
evaluate to ensure adequate adhesion. Carefully gun
the sealant with a smooth, continuous bead. If tooling is
needed, do so within fteen minutes of application.
Caution
Avoid prolonged contact with skin. Uncured adhesive
irritates eyes. In case of contact with eyes immediately
ush with water. Call a physician. Please refer to the
SDS for rst aid information.
See www.chemlink.com for most current SDS .
KEEP OUT OF REACH OF CHILDREN.
• Horizontal applications will require tooling.
• In areas where prolonged chemical exposure is
anticipated, contact Technical Services for
recommendations.
• Allow treated wood to “cure” for six months prior to
application per APA guidelines.
• Do not use in areas subject to continuous immersion.
• Do not store in elevated temperatures.
• Allow asphalt to cure a minimum of six months before
applying M-1
®
• Remove all coatings and sealers before application.
• Please contact customer service for application
guidelines with temperatures below 32°F (0°C).
• Test and evaluate all paints before application.
Polyurethane and oil based paints may dry slowly.
• Do not use on TPO without CHEM LINK TPO primer.
• Does not bond to Kynar 500
®
PVDF coated metals.
