SerpiMastic
™
Heavy Duty
Asbestos Encasement Coating
Benets

USEPA contract
• Weather and UV resistant
• Interior and exterior application
• High solids and high build formula
• Sprayable and trowelable options
• London Underground approved*
Product Description
SerpiMastic is a water-based, high-
solids, high-performing mastic coating
trusted worldwide for 4+ decades as
an encapsulation/encasement solution
that abates ACM (Asbestos-Containing
Materials) and coats friable insulating
materials to protect against physical
damage and to seal in potentially
hazardous particulates such as asbestos
or some silica.
Indoors or outdoors, SerpiMastic is
a tough, weather-resistant bridging
encapsulant and protective membrane
providing high impact protection.
SerpiMastic inhibits friable ber
release and arrests deterioration on a
wide range of building systems and
structural surfaces: cement asbestos
sheet or millboard used to form interior/
exterior walls and sloped roofs); TSI
(Thermal System Insulation) and HVAC
systems (e.g., boilers, pipe lagging, and
duct exteriors); High density ACM or
non-ACM cementitious Spray Applied
Fireproong (aka PFP, SFRM
†
over 39+
pcf); ACM-containing paint and stucco;
ACM acoustical surfaces/soundproong;
previously painted popcorn ceilings;
oor underlayments; Galbestos, and
similar felt, textile and canvas ACM
pressed into structural elements; and
to lockdown over residual adhesive on
oors
††
where tile or carpet has been
removed.
Features
• Impact resistance of over 160 PSI;
practically indestructible
• Exhibits excellent chemical resistance
to help seal insulating materials and
protect against the penetration of
liquids
• Repairs damaged insulation.
SerpiMastic adheres tenaciously to
most insulation materials as well as
other common construction surfaces
• Water-based, very low VOCs
• Can be used indoors and outdoors
• SerpiMastic is classied by
Underwriter’s Laboratories under
category CBUI Encapsulants, and
ICP participates in the UL stringent
QA/QC inspection program for
SerpiMastic manufacture
Application and Equipment
Recommendations
Before performingany repairs to
asbestos containing material, contact
your local authorities to ensure
compliance with local regulations.
Consult the full SerpiMastic specication
for detailed recommendations.
Surface Preparation: Surfaces
to be protected should be free
of excessive loose dirt or oil.
SerpiMastic will bond tightly to
virtually any clean surface. Prepare
surfaces in an asbestos-safe manner
whether asbestos status is “hot”
(positive), presumed (PACM), or
unknown as any uncontrolled
friable ber and particulate release
is poor work practice and potential
hazard. Work damp or wet to control
particulates.
Priming: SerpiMastic has tenacious
adhesion to most construction
materials. A primer for adhesion would
not be necessary for clean, dry, unglossy
and sound surfaces.
For cementitious surfaces exhibiting
aging, chalking, spalling and similar
gradual deterioration, use Fiberlock’s
GripTack™ multi-purpose adhesive
to serve as primer and penetrating
encapsulant. GripTack will enhance the
dimensional stability of deteriorating
surfaces to provide SerpiMastic with a
surface receptive to adhesion.
Asbestos Abatement
Products
*Must be applied at an application rate not to exceed a
dry lm thickness of 1mm. See application instructions
and installation notes for complete details on London
Underground applications.
† PFP: Passive Fire Protection; SFRM: Sprayed Fire
Resistive Material. SerpiMastic is ideal for high-density
reproong with a look and feel as if concrete; and may
be used in areas where durability is required because
surfaces receive repeated impact.
††
Ideal as a lockdown, SerpiMastic alone is insufficient as a
walking surface without additional protection, and should
never be used on surfaces with vehicular traffic.
