Applications & Product Overviews:
 
BASF Master Builders part number Cross Reference Guide
 
General Specification for Sealants and Joints.  Use either butyl sealant conforming to ASTM C-1085; latex sealant conforming to ASTM C-834; polyurethane or polyether or silicone sealant complying with ASTM C-920.
 
Duralink: We recommend Duralink for its optimal adhesion and long lasting performance. Duralink is great for metal roofing, very high-movement applications, difficult environments or the best overall performance. Its advanced hybrid sealant chemistry provides for +/-50% joint movement and has superior adhesion to glass, wood, all roofing materials.  Duralink has a 25 year life expectancy. Duralink is 100% solvent free, 100% solids, very low odor (use indoors), zero VOC, quick curing and low temp curing (down to 30F). Superior adhesion AND +/- 50% joint movement, 750-800 %+ elongation, 250-300 PSI 0+ tensile. Adheres to nearly everything including Kynar coated roof metals, siliconized paints, metal with acrylic finish, vinyl siding or vinyl clad windows, glass, metals, EFIS, foam, plastics, concrete, stone, wood, BUR, cured asphalt and more. Will not stain limestone or marble. USDA compliant. Stocked in all popular colors. Quick Curing. Paintable
 
M1 is recommended for roofing membranes made from EPDM, TPO modified bitumen and PVC type materials. TPO Primer first on TPO.
For shingle adhesive on fiberglass / asphalt shingles M1 structural sealant is recommended. M1 has 400 PSI tensile and 400-450% elongation. M1 is also a great general purpose sealant. 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.
 
Sonolastic Clear 25 is a great translucent-clear, non-staining sealant for glass & window, tile, siding, car windows and structural adhesive applications, use  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.
 
NP1 is a very popular solution for most construction caulking and structural sealant applications. 800% Elongation and 350 PSI tensile. Available pre-tinted in standard colors. It has superior adhesion and is suitable for +/-35% total joint expansion applications such as window frames, roofing tile, panel walls, parapets, vinyl siding, stucco, and in deck joints.
 
NP-2 is custom color tintable and handles up to 2" joint width at 50% movement, and the cure can be accelerated; 280% elongation and 160 PSI tensile.
 
SB-1800 provides very quick cures, medium tensile (360 psi), and can be applied down to -20F. Used where very rapid assembly, thick larger areas are bonded, or cold weather sealing is important. Used sheet metal, truck bodies, shipping containers, spot welding (apply SB-1800 between overlaps and weld immediately - through the metal & sealant).
 
SB-188 high performance silicone sealant is used to seal to silicone rubber surfaces and high-temperature, electrical applications, and extreme environments (-75F to +500F).
 
SB-190 clear for super strength 2000 psi (cures more slowly in regular temperatures). Commonly used for snow guard. Not for expansion joints.
 
1-Part is a light gray, highly flexible, self-leveling moisture curing pourable sealer. Its 100% solid rubber, has no V.O.C. (volatile organic content), will not melt or shrink, is UV resistant and is resistant to deterioration.
 
Concrete Expansion Joint Products:
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 very cost effective. 300% elongation, 150 PSI tensile, abrasion resistant (pedestrian traffic suitable). Its a easy to use single-component product useful for joints up to 2" wide. Novalink is asphalt compatible (aged asphalt).
 
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 in 40 Standard colors and 470 custom colors. Sonneborn SL1/SL2 is not asphalt compatible
 
Sonomeric 1 is a single component Self leveling polyurethane sealant which is Jet fuel and resistant to many chemicals. It has 1200% elongation.
 
TX1 Textured Sealant
House Stucco & Grout: Try Sonneborn TX1 caulking instead of NP1. It dries with a nice textured finish similar to stucco or grout. It's the same chemistry as NP1. TX1 is easy to tool with a consistent appearance. Its available pre-tinted in many popular colors.
 
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.
 
Sealant 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-772UNI-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:
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.

Exterior Caulk vs. Sealants:

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 due to their super adhesion and toughness. Today, polyurethane sealants (still called caulks by many) are specified for most roofing and waterproofing 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 100% solids and chemistries are based on Silyl-terminated polyethers.

 

Phil Georgeah, President of Chemlink, comments â€œ(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, cure faster than silicones and many older urethanes and are odor free. 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.

 

EIFS Construction and Joint Design: See the EIFS Guide for details.  Trouble-free EIFS application is accomplished by forming a 1/2" to 3/4" sealant gap wherever EIFS meets a non-EIFS material, such as roofing, trim, or doors and windows, according to the EIMA EIFS Guide. The correct gap makes it possible to finish the exposed edges of the expanded polystyrene, which should be wrapped with reinforcing mesh before the EPS is secured to the sheathing with a waterproofing application of base coat. Then the rest of the finish goes on. Finally, the gap is filled with soft or closed-cell backer rod and a bead of compatible sealant. Novalink Polyether Sealant is an excellent sealant for this applications. Textured Sealants are also available which cure textured to look stucco-like.

 

Joint Design (typical -- see individual product data sheet):
Install all joint applications per ASTM and SWRI recommendations and guidelines. Joints shall be designed with a depth to width ratio of 1:2 (joint depth one-half the width). It is recommended that the joint shall be no less then ¼” wide by ¼” deep (6 mm x 6 mm). The maximum depth of sealant shall be ½” (13 mm). The maximum width is 2" (certain materials; some are limited to 1"). Control the depth of the sealant by using a backer rod that is 25% larger then the joint opening at 75F temperature. Where the joint configuration will not permit a backer rod, it is recommended that an alternative bond breaker be used. Prevention of three-point adhesion is necessary through the use of a backer rod or bond breaker tape to ensure proper joint movement and a long lasting weatherproof seal.

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.
