SURFACE PREPARATION      
    
    
    

Concrete:
Concrete should be structurally sound, free of dust, dirt, loose paint. All concrete surfaces should be blast tracked or scarified for the best results. New concrete should be etched with a 25% solution of muriatic acid and then rinsed with fresh water 3 times.

Steel:
Steel surface should be free of dirt, dust, grease, oil or paint. The best results are achieved by sand blasting the steelto white metal.

Mixing:
Premix part-B hardner. Mix one part base part-A to one part hardner part-B by volume. Mix thoroughly until uniform color is achieved by scraping sides and bottom.

Application:
As a bonding agent: Mixed material can be applied by roller, brush, or spray. Fresh concrete should be applied before adhesive becomes tack free.

As a mortar: To each mixed part of PolyBond - 300 add 3-4 parts of sand (Flint shot) and mix thoroughly. This mortar can be applied with a trowel.


TEMPERATURE LIMITATION      
    
Do not apply below 40°F. The temperature should be 40°F and rising
