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 specic 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 applicators 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.
Shelf Life
Twelve months from date of manufacture when
stored at 70°F / 21°C with 50% relative humidity.
High temperature and high relative humidity may
signicantly 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.
Limitations
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.
