Supersedes: New
Ref. #: 643185
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 Clear 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 minimum recommended joint width is 1/4” inch and the maximum recommended joint width is 5/8” inches (15 mm). See table below.

DIRECTIONS
Fillet Joint Design
• Dimension A and B must be a minimum of ¼
• Dimension C must be a minimum of ⅜"
Control Joint Design
• Dimension A must be a minimum of ⅜" or maximum of ⅝"
• Dimension B must be a minimum of ¼" depth
• Dimension C can be a maximum of ½"
Dynamic Joint Design
• Dimension A can be up to 5/8” wide
• Dimension B must be 3/8” in depth
• Dimension C must be a maximum depth of ½”
NOTE: Form bead to a concave shape keeping sealant inside the joint edges. DO NOT bridge the sealant or smear beyond the joint
edges otherwise it may result in whitening of the sealant on prefinished siding and trim materials. Tooling spatula recommended.
Size to joint width. Use masking tape to prevent smearing of sealant if necessary.
Bedding Bead Structure
• Dimension A must be a 3/8” rounded sealant bead
• Apply sealant to substrate.
• Minimize pressure when applying sealant to maintain
a rounded bead
• Compress sealant between both substrates
• Avoid excessive substrate movement after
compression. Movement of the substrates can smear
sealant and breakdown the sealants capacity to
maintain a seal.
