Applications & Product Overviews:
For very high-movement applications,
difficult environments or the best performance we recommend
Sonolastic 150 VLM
sealant. Its advanced
hybrid sealant chemistry
provides superior adhesion to
glass, wood, all roofing materials, swimming pool deck/wall joints and has
a 25 year life expectancy.
For roofing membranes made from EPDM, TPO modified bitumen and PVC type materials,
M1
is recommended. Use TPO Primer first on TPO.
For shingle adhesive on fiberglass / asphalt shingles
M1
structural sealant is recommended.
M1 can also be used to create containment seals between walls and floors of
storage rooms for oil based products. For example, between a metal wall and
concrete floor.
M1 will cure under water and can be used for emergency wet repairs, applying
pool tiles. Its important to wire brush then "work" the product into
the surface to create good adhesion.
For Kynar coated roof metals, metal with acrylic finish, vinyl siding or
vinyl clad windows we recommend
Duralink
or
Sonolastic 150 VLM
for
its optimal adhesion and long lasting performance.
A great translucent-clear, non-staining sealant for glass & window, tile, siding,
car windows and structural adhesive applications,
use Sonolastic Clear 25. It is used
throughout in the automotive industry for window glass installation, trim
adhesive and for general sealing. With good UV resistance and strength, it is also widely used as a roof tile
adhesive and as a snow-guard adhesive.
For most construction caulking
and structural sealant applications,
NP1
is a very popular solution. It has superior adhesion and is suitable for +/-35% joint expansion
applications such as window frames, roofing tile, panel walls, parapets,
vinyl siding, stucco, and in deck joints.
Where very rapid assembly or
cold weather sealing is important,
SB-1800 provides very quick cures,
medium
tensile (360 psi), and can be applied down to -20F. Use for of snow
guards, sheet metal, truck bodies, shipping containers, spot welding (apply
SB-1800 between overlaps and weld immediately - through the metal &
sealant).
Use
SB-190
clear
for super strength 2000 psi (cures more slowly in regular temperatures). Not
for expansion joints.
Concrete Expansion Joints:
Novalink
SL Self
Leveling concrete expansion joint sealant is 100% solids (non-shrinking),
solvent free (very low order on cure, suitable for indoors), quick curing
(can apply down to -32F), and is very cost effective. It 300% elongation, 150 psi tensile,
high abrasion resistance (pedestrian traffic suitable). Its a
convenient single component product useful for joints up to 2" wide.
SL1 and
SL2
are great concrete expansion joint sealants and are used for public
walkways, driveways, swimming pool decks, road expansion joints parking lot joints, pavement joints, driveway expansion joints,
road joints, exterior deck expansion joints and such. SL2 is used for
wide joints and is tintable. SL1/SL2 are not asphalt compatible.
House
Stucco:
Try Sonneborn
TX1 caulking
instead of NP1. It dries with a nice textured finish which
closely matches stucco or grout. It's the same chemistry as NP1.
TX1 is easy to tool with a
consistent appearance. Also try the off-white color. It's natural
light-cream look and slight texture provides a pleasing appearance.
For above water line pool deck-to-wall grout repairs,
both
M1
and
ULTRA
are excellent. These sealants survive the stresses that cause mortar grout
cracking. Ultra has excellent dirt pick-up resistance. Dirt
and hard-water pool
deposits are easily removed! NOTE: It is very important to keep the pool wall-to-deck interface
waterproofed, as constant chemical and water exposure quickly corrodes the
steel re-bar, resulting in structural damage. M-1 can be applied for in wet
emergency repairs (resetting / re-grouting tiles) and will cure quickly.
PRIMERS: Where substrate adhesion is
questionable, or in constant submersion situations, primers should be used.
Primer-733 is an easy to use one-component solvent based sealant primer
for use with urethane sealants applied to metal, wood and coated surfaces.
Primer-2000 is
easy to use one-component solvent based sealant-primer
for use with Sonolastic 150 / polyether sealants applied to porous surfaces,
concrete, grout, stucco and wood. For TPO roofing,
TPO PRIMER
is recommended. A favorite of many deck waterproofing
contractors is Polyprime 2180. Its a
2-part epoxy-polyamine primer. For a easy to use on-component wood &
concrete primer, try
Primer-772.
UNI-TILE SEALER is a two-component, quick
drying epoxy-polyamide penetrating primer/sealer which penetrates and seals
porous surfaces to improve adhesion -- excellent on concrete and pool decks.
UNISEAL Primer
is a one-component water based penetrating concrete sealer.
Backer
Rod
is
an easy to compress soft celled foam. It is inserted into a clean joint at
required depth before caulking/sealing. Backer Rod creates an even depth and
supports the caulk. The even depth is important to create the correct
width-to depth ratio (~3:1) for the expansion joint.
Select a backer-rod diameter that is about 25% larger than the nominal width of the joint.
Backer rod sizing and
installation information is at the bottom of this page.
Butyl Rubber
Tape Sealant is a premier elastomeric butyl rubber sealant designed to
meet the critical requirements of metal buildings. It also meets or
exceeds all sealing requirements for window glazing, air conditioning,
and refrigeration. MB-10A is extruded on silicone coated paper for
easy application.
BARR
Waterproofing liquid
mastic.
The
BARRtm
is a waterproofing sealant that cures by
exposure to atmospheric and/or substrate moisture. It can be used
in all types of applications! Above grade this versatile sealant
is used for waterproofing construction materials, from roofing
systems, sealing parapets, lining gutters and valleys, to planter
boxes, as a horizontal joint sealer on parking decks, on concrete
transition joints between horizontal and vertical masonry, and for
sealing cracks in concrete or asphalt paving. In mechanical
construction, BARR is used for lining and waterproofing
condensation pans and cooling towers. Below grade BARR
is used for foundations, between-slab waterproofing, swimming pool
construction and other underground applications.

Exterior Caulk & Sealant Application
Guide
Selecting the
right sealant or caulk for your exterior application can be
confusing. Over the past decades, many improvements have been made
and new chemistries developed enabling greater performance and
expanded applications.
Caulks vs.
Sealants: Some manufacturers use the terms "Sealants & Caulks"
interchangeably. Sealants are designed to seal an interface which has
movement. Caulks are designed to fill a gap. Sealants are designed to
create a
long-term seal that stays intact and prevents moisture
ingress and are UV resistant. Sealants deal with greater joint movement, extreme
temperatures and have very low shrinkage. Class A sealants have +/-25% joint
movement capability. Polyurethane (urethane) based
sealants are now the most widely used product in the roofing and waterproofing industry. Today,
polyurethane sealants (still called caulks by many) are specified for most roofing details.
They are used extensively in flashings, termination bars, reglets,
copings and pitch pans. Upgrades from this are polyether based
sealants which can have +/- 50% to +100/-50% expansion capability.
Examples include Sonolastic 150 VLM.
Exterior grade
weatherproof sealants, such as NP1, TX1 and Sonolastic 150 are high performance polyurethanes
which have excellent performance for sealing most interfaces.
"Painters caulks" are price-driven products serving markets where
performance is subordinate to economy. Painters
grade caulks have limited movement capability; usually less than
12 percent movement before cracking, delaminating, peeling or
permanently deforming. Painters caulks shrink quickly over time and have limited
(short-term) weathering properties (poor UV resistance).
They are NOT DESIGNED FOR long term UV exposure. Painters grade caulks are
are based on less expensive polymers such as linseed oil, polybutene, asphalt, butyl rubber, SBR
rubber, vinyl acetate and acrylic latex. Do not use
these products in exterior applications or where joint movement can be
greater than 12%.
Sealants are
a different class of product designed for exterior use and long term
performance. Very high-performance
sealants are based
chemistries based on Silyl-terminated
polyethers.
Phil Georgeah,
President of
Chemlink, comments “(painters) caulk
becomes hard & brittle and cracks, splits or severely chalks within
three years. These caulks often shrink, sometimes losing up to 30 percent of
their volume from solvent loss, condensation or oxidation. Shrinkage
applies excessive stress at the interface between the construction
material and the caulk mass. (Painters) caulks generally exhibit fair to poor
adhesion on construction materials. Adhesion failure gets worse with
increased volume shrinkage. Most
caulks are designed for the “do-it-yourself” market, or should I say,
the “do it to yourself” market."
Although silicone
sealants generally have good adhesion, they do not always perform well in roofing
or stucco applications where heat and oil migration from
roofing substrates or house-wraps tend to degrade adhesion. Silicones
also do not
provide good long term paint adhesion and are difficult to repair
(silicone does not like to stick to cured silicone).
New on the market are sealant chemistries such as Polyether
which have
very
aggressive bonding to most materials,
skin over, and cure much faster than silicones and many older urethanes.
They exhibit very little dirt pickup. These products bond like
traditional silicones but are both paintable and more cost effective.
Polyether sealants with VERY
low modulus (soft) are also now available. For example
Sonolastic 150 VLM. These low-modulus materials are
capable of up to 1,200 percent elongation and offer far greater
durability in applications with great movement than either standard silicone or urethane.
In addition, very little moisture is required to trigger a rapid polymerization
reaction in polyether sealants, so they cure quickly too.
How To Apply Backer Rod and
Sealants:
1. Where priming of the surface
material is necessary, primer should be applied only to the sides of
the joint surfaces and allowed to dry
tack-free before the Backer-Rod is placed. DO NOT prime the Backer-Rod.
2. Follow suggestions for joint-sealant application as directed by
the sealant manufacturer.
3. Tool to desired shape using a caulking
tool or old spoon.
Hint: For polyurethanes, wet the tool regularly with water or
toluene to enable a smooth
surface. Soapy water is not recommended as some soaps can interfere
with joint bonds.
4. Most products need 24 hours
minimum cure before applying any type of over-coating. Follow the
manufacturers recommended cures.
HINT: For
those not who are not professional applicators, use masking tape on
surfaces where you do not want sealant. It is very difficult
to remove from unwanted areas.
