centrifugal blasting

p.2-36
what size profile should be left on the deck?
3-4.5 mil profile

p.2-36
after an abrasive blast how is the surface profile determined?
by using a replica tape system

p.2-36
replica tape measurement readings of the surface profile are kept where?
are kept as part of a permanent record of a nonskid job

p.2-36
how is the replica of the surface profile measured?
by the use of a micrometer

p.2-36
controlling the standard mil profile is dependent on what?
the size of shot in relation to the speed of the blasting machine

p.2-36
for application of primer how should the surface appear?
a near white metal blast cleaned surface is required

p.2-36
how soon should the primer be applied after the metal is cleaned?
to lessen the possibility of rusting or other surface contamination the primer should be applied 1 hour after the metal is cleaned

p.2-36
what is the maxium time allowable to apply primer to cleaned metal?
six hours

p.2-36
if primer is not applied within six hours of being abrasive blasted what action should be taken?
