EB550 SBR

Liquid Bonding Admixture

EB550 SBR is a non re-emulsifiable, high solid, liquid bonding admixture for improving physical properties, cure and adhesion of Portland cement and gypsum mixes.

Composition: EB550 SBR is a milky white, emulsion of high solids, acrylic polymers and modifiers in a special formulation.  EB550 SBR is non-yellowing and has excellent resistance to ultra-violet degradation, heat and most common chemicals.  EB550 SBR does not alter the color of the mixture.

APPLICATION

Surface Preparation:  surface must be structurally sound, clean, free of dust, dirt, oil curing or form release compounds, paint, laitance, efflorescence and other contaminants.  New concrete and masonry surfaces must be cured 28 days.

 

Cleaning: clean tools and equipment with water immediately following use.  Clean drips, spills and smears while mix is still wet.  Mixes containing EB 550 SBR are extremely difficult to remove if allowed to dry before cleaning. Clean tools and equipment with water immediately following use.  Clean drips, spills and smears while mix is still wet.  Mixes containing EB 550 SBR are extremely difficult to remove if allowed to dry before cleaning.

 

Provide an absorptive surface on all substrates including smooth pre-cast or formed concrete, by abrading the surface.

 

Mixing: Stir EB550 SBR slowly and thoroughly using slow speed mixing equipment in a clean container.

 

Gauging Liquid: mix 1 Part EB550 SBR with 3 parts water.

 

Bonding Slurry: dry mix 1 Part Portland cement with 3 parts dry sand and add undiluted EB550 SBR to produce a pourable slurry coat.  Brush mixture thoroughly into voids and pores of surface, to eliminate air pockets.  Before slurry coat dries, follow immediately with field mixed or manufactured patching materials that are compatible with Portland cement.

Application: use only light pressure on trowel, and finish with as few strokes as possible.  Keep trowel clean and wet to prevent sticking.  Mixes with EB550 SBR do not normally require curing, but it is advisable to cover with moist burlap for 24 hours.  Air cure surface for 2 to 4 days for normal use, and 4 to 7 days for heavy traffic areas.

 

Cautions: do not apply mixes modified with EB550 SBR when temperature is below or expected to fall below 2°C.  Do not use with air-entrained cements.  Excessive moisture and high humidity will slow curing time.  Air cure cisterns, tanks or pools for a minimum of 6 to 9 days before filling with water.

STORAGE

The product should be stored in a cool, dry storage place for one year in unopened container. Stir or agitate the container before use. Do not store at temperatures below 10°C or in direct sunlight.
