Water-Tight EVA Foam Expanison Joint System
Epoxy.com Product #63
GENERAL DESCRIPTION
Epoxy.com™ Product #63 is a water-tight cross-linked closed-cell Ethylene Vinyl Acet ate
expanded foam material that exhibits unique properties when used in expansion contraction
joints. Epoxy.com ™ Product #63 is water-tight and exhibits good chemical resistance
properties to most mild non-oxidizing acids, alkalines and petroleum products.
Traffic will not embed dirt and sand in Epoxy.com ™ Product #63 as is characteristic with
most pourable joint materials. It resists road salts and petroleum spills normally
associated with highway traffic and oil storage.
The material remains very flexible, is non-extrudable, and may be custom cut to fit any
shape. Fabrication of Epoxy.com ™ Product #63 may be accomplished through a heat-welding
method on the job-site to make alterations or fabrications, etc., to meet the job
requirements. Care must be taken in that the finished joint is not exposed to direct
flame, thus protecting the material properties.
USES: Bridge Decks, Water Tanks, Chemical Storage Areas, Stadiums, and most
vertical, horizontal, or overhead concrete or steel joints 3/8 inch or larger that require
a long lasting, positive water-tight Joint.
SURFACE PREPARATION
Longevity of the joint and its ability to remain water-tight is primarily dependent
upon good surface preparation. Durability will be extended by following the suggested
recommendations.
CONCRETE & MASONRY SURFACES:
(a) Sandblast or waterblast surface to remove laitance, sharp edges, protrusions or
other contaminants which will interfere with the bonding agent.
(b) New concrete should cure to 80% of the design strength before application of joint.
STEEL SURFACES:
(a) Surfaces must be sandblasted to gray metal immediately before application.
(b) Surfaces must be clean and sound.
SAWCUT SURFACES:
(a) Sandblast or waterblast surface to remove any contaminants left on surface from
cutting.
REPLACEMENT OF EXISTING JOINTS:
(a) Remove old joint material, backer-rod and other associated materials in joint
opening.
(b) Repair all damaged nosing with Epoxy.com Product #15 - (Epoxy Mortar)
or Epoxy.com Product #10 Mortar
(c) Sandblast or grind existing substrate to remove all unsound concrete, oils, greases
and old bonding agents. (The substrate must be clean and sound to assure positive
adhesion.)
APPLICATION
(a) Calculate movement of span to determine correct size of joint to be installed. Using
the shape factor for joint sealant materials the measurement of the depth should never
exceed the measurement of the width.
(b) Epoxy.com Product #63 should be compressed into the joint opening to a point where it will
NEVER BE IN CONSTANT TENSION over long periods of time. It also should be installed in a
way that will not exceed 50% in compression. Under over compression the material will
develop a compression set.
(c) apply Epoxy.com ™ Product #2006 evenly to both
inter surfaces of the nosing and both sides of the Epoxy.com ™ Product #63 with
a small brush or putty knife. (
(d) Compress joint into joint opening and remove all excess bonding material.
(e) Use a Teflon coated iron to heat weld Epoxy.com Product #63 into continuous lengths.

This chart is intended as a guideline for the specifier and installer.
Many other conditions may have an effect upon the materials and should
be taken into account before specifying, ordering or installing the material. Some of these factors are: length of exposure, chemical concentration,
temperature, static and dynamic loading. Please contact the technical department if there are further
questions.
