Surface Preparation:
All surfaces must be structurally sound, solid and completely
clean, including the removal of form release, existing sealers,
paints, patching compounds, weak or loose areas, dust, dirt, oil
or any other contaminant which may act as a bond breaker.
Where required to obtain a solid surface substrate preparation
must be by mechanical means such as grinding or sandblasting.
Substrate must be primed to ensure proper hydration of the
patch. Use Starpatch Bonding 900X. Allow bonding agent to
become tacky before applying Supa – Bond.
Mixing Instructions:
Add the mortar powder to water that has been placed in a clean
bucket until the desired consistency has been achieved. For an
entire 22.7kg/50lbs bag add 3.8 litres (4.02 quarts) of clean
water. Use a slow speed (300 to 400rpm) paddle mixer or for
smaller quantities a margin trowel. Mix Supa – Bond for 2 to 3
minutes. Always place water in your mixing container before
adding the mortar.
Application:
• Apply one layer at a time. Each layer must not exceed ¾”.
• Temperature at time of application may not be lower than
5°C/41°F or greater than 35°C/95°F.
• For voids deeper than ¾” dry pack the void with Supa –
Bond and finish the final layer with Supa – Bond mixed to
normal consistency.
• Avoid having material exposed to excessive heat and/or
direct sunlight.
