2.02 MATERIALS
SPEC NOTE: SEALTIGHT REZI-WELD LV Low Viscosity Injection Epoxy is a two-component,
100% solids, clear epoxy adhesive binder. It resists most chemicals, is
moisture insensitive, offers high-modulus, high-strength and self-leveling
characteristics.
SEALTIGHT REZI-WELD LV can be used where its easy flowing, thin consistency
would be advantageous such as larger pressure injection projects requiring
mechanical equipment, securing machinery base plates to concrete floors,
interior, non-skid pathways or certain bonding applications. REZI-WELD
LV can also be mixed with sand or aggregates to make a simple-to-use,
economical epoxy mortar ideal for patching or grouting defects in concrete
substrates requiring high impact resistance.
A. Injection Epoxy: two-component, 100% solids, low viscosity injection product. It is to be moisture insensitive, chemical resistant, high modulus, high strength, self-leveling, VOC-compliant and in conformance with ASTM C 881, Types I, II, IV and V, Grade 1, Classes B and C, SEALTIGHT REZI-WELD LV, manufactured by W. R. MEADOWS, INC.
PART 3 EXECUTION
3.01 EXAMINATION
A. Verify substrate conditions under provisions of Section [ ].
3.02 PREPARATION
A. Surfaces must be free of standing water and completely clean of dirt, rust, curing compounds, grease, oil, paint, waxes and other materials which would prevent a solid bond.
B. Clean concrete by sandblasting to a sound surface. Vacuum or blow dust away with compressed air.
C. Concrete contaminated with only laitance and dirt, other than grease or oil, may be acid etched. Smooth surfaces, such as wood, or cured epoxy, require sanding or other mechanical abrasion. Sandblast exposed steel surfaces and vacuum clean; if not possible, degrease the surface and use sandpaper or a wire brush to reveal continuous, bright metal.
3.03 INSTALLATION
A. Observe mixing and application information and precautions stated in manufacturer's literature.
B. Install in accordance with manufacturer's instructions.
3.04 CLEAN-UP
A. Clean tools and equipment immediately with Xylene or Toluene. Clean equipment away from heat, sparks and open flame and avoid breathing vapors or allowing epoxy-containing solvent to contact skin. Should this material come in contact with the skin, wash thoroughly with soap and water.
3.05 PROTECTION OF FINISHED WORK
A. Protect finished Work under provisions of Section [01500].
