Preparation of New Building or Major Refurbishment
For potable water tanks, the entire tank must be blast cleaned to a minimum of Sa2½ (ISO 8501-1:2007). A sharp angular surface profile of 75-100 microns is recommended. If oxidation has occurred between blasting and application of Interline 975, the surface should be reblasted to the specified standard. Surface defects revealed by the blast cleaning process, should be ground, filled, or treated in the appropriate manner.

Material is supplied in two containers as a unit. Always mix a complete unit in the proportions supplied. Once the unit has been mixed it must be used within the working pot life specified. Agitate Base (Part A) with a power agitator. Agitate Curing Agent (Part B) with a power agitator. Combine entire contents of Curing Agent (Part B) with Base (Part A) and mix thoroughly with power agitator.
