OSI® QUAD® MAX
Window, Door & Siding Sealant
Page 3 of 4
Directions:
Tools Typically Required: Utility knife and caulking gun. For best application results, OSI recommends the use of a high quality
caulking gun such as the Albion® B12 Cartridge Gun.
Safety Precautions:
Wear gloves and wash hands after use.
Surface Preparation: Ensure all surfaces are clean and free of old caulk, grease, dust, ice, snow, frost, surface water and other
contaminants. While QUAD MAX is generally considered a non-priming sealant, special circumstances or substrates may require
a primer. It is the user’s responsibility to test substrate compatibility and the adhesion of the cured sealant on a test joint before
applying to the entire project.
Masonry: Concrete, stone, stucco and other masonry must be cleaned where necessary by grinding or wire brushing to expose
a sound surface free of contamination and laitance. Concrete must be fully cured and free of release agents.
Wood and painted wood: New and weathered wood must be clean and structurally sound. Cut back weathered surfaces and
dry rot until clean, sound wood is reached. Scrape away paint to bare wood. Any coating that cannot be removed must be tested
to verify adhesion of the sealant. QUAD MAX will adhere to most new and old, dry, oil-free wood.
Metal: Remove scale, rust, and residue from metal to expose a bright metal sheen by wire brushing. Remove any chemical
residue, film/oils, and loose or incompatible coatings using the appropriate solvent. Any coating that cannot be removed must be
tested to verify adhesion of the sealant. Remove any other coatings or finishes that could interfere with adhesion. An adhesion
test is recommended for anodized aluminum or any questionable substrates.
Joint Preparation: The number of joints and the joint width should be designed for a maximum of ± 50% joint movement from
the initial joint width. The depth of the sealant joint should be one-half the width of the joint. The maximum depth is ½ inch (13
mm) and the minimum is ¼” (6 mm). The maximum recommended joint width is 5/8” inches (15 mm). See table below.

5/8 1/2 15 13
If the depth of the joint exceeds 3/8” (9.5 mm) the use of a backer rod such as a Closed-Cell Backer-Rod or Soft Backer-Rod is
recommended. Where the joint depth does not permit the use of backer-rod, a bond breaker (polyethylene strip) must be used
to prevent three-sided adhesion. To maintain the recommended sealant depth, install backer-rod by compressing and rolling it
into the joint channel without stretching it lengthwise. Closed-Cell Backer-Rod should be approximately 1/8” (3 mm) larger in
diameter than the width of the joint to allow for compression. Soft Backer-Rod should be approximately 25% larger in diameter
than the joint width. Backer-rod becomes an integral part of the joint. The sealant does not adhere to it, and no separate bond
breaker is required. Do not prime or puncture the backer-rod.
General Preparation: The temperature of the product, the surfaces and the working area should be between 0°F (-18°C) and
140°F (60°C). For best performance, store cartridge at room temperature at least 24 hours before use. Cut plastic nub of cartridge
then screw on plastic nozzle. Insert cartridge into caulking gun, cut nozzle at a 45° angle to desired bead size (3/8” is
recommended for optimal joint protection).
Application: Using a caulking gun, apply sealant with steady pressure, forcing sealant into joint. If the depth of the joint exceeds
3/8” (9.5 mm) the use of a backer rod is recommended. OSI QUAD MAX will not pop or splatter and will dispense smoothly on
extrusion from the cartridge. Tooling of the sealant is allowed. Full cure may take 24-72 hours or longer depending on ambient
conditions and volume of sealant used. Sealant is paintable in 1 hour. Latex paint is recommended. If using oil based/alkyd
paint, a latex primer should be used first.
Users can refer to ASTM C1193 – Standard Guide for Joint Sealants for further installation/application information. Henkel
recommends that you test all sealant applications under simulated or actual end use conditions to ensure the product meets or
exceeds all required project specifications. Since assembly conditions may be critical to the product’s performance, it is also
recommended that testing be performed on specimens assembled under simulated or actual production conditions.
Clean-up: Clean tools and uncured sealant residue immediately with mineral spirits or paint thinner. Cured sealant must be
carefully cut away with a sharp-edged tool.
