HOLD*BLAST
TM
Surface Passivator
DIRECTIONS
The use of this product is to prevent flash rust through surface passivation
Apply HOLD*BLAST
TM
in a dilution of 1:50 with potable water directly onto the substrate (1 part
HOLD*BLAST to 50 parts water). Sufficient product must be applied uniformly across the substrate to
thoroughly wet the surface, with no areas missed. This may be accomplished by various methods, such as
pressure washing, airless sprayer, conventional sprayer, UHP waterjetting, wet abrasive or mist/vapor blasting.
Dilution may possibly be increased with good quality water and/or low soluble salt contamination levels.
On vertical surfaces, it is recommended that work start at the top and progress downwards. With wet abrasive,
slurry, or vapor/mist blasting, it is recommended that surfaces be rinsed with the diluted HOLD*BLAST solution
with the abrasive valve shut off for removing any particulate matter from the surface. After the substrate has
been thoroughly washed it should be allowed to dry, or be dried, prior to coating application. Remove any
excess or ponded water by use of compressed air or squeegee or other means.
Poorer quality water can often be used, but will require a higher concentration of HOLD*BLAST. Water quality,
salt contamination levels, humidity and temperature are all variables that can affect dilution rates and results.
Test on a small area and adjust the dilution rate until the desired results are obtained.
It is highly recommended that a minimum of a 1500 psi pressure washer be used. This is to ensure “driving" the
solution into the profile of the surface.
Typical time for “holding the blast” is approximately 72 hours or longer. Wetting of the surface with rain, dew
or condensation will cause the surface to rust. In highly humid environments, with surfaces contaminated with
low salt levels, the 1:50 dilution should be sufficient. In low humidity and low salt levels the dilution ratio may be
extended.
Before application of HOLD*BLAST, surfaces should always be tested to assure soluble salt limits are at a
specified or acceptable level. (Testing after the application will mask the presence of surface salts under the
passivation layer.) High levels of soluble salts will cause premature coating failure and degradation of the
substrate. Test for levels of chloride with the standard CHLOR*TEST kit. Test for levels of chloride, sulfate and
nitrate with the CHLOR*TEST ‘CSN’ kit. Both kits offer the highest degree of accuracy and are the easiest to use
of any complete field test kit available.
This product leaves no chemical residue, is biodegradable, non-hazardous and is a safe and effective
alternative to hazardous chemical rust inhibitors. HOLD*BLAST treated surfaces do not need to be rinsed;
merely remove any excess spent wash water.
