-
Acid etch with 5% Hydrochloric acid, wash clean with
water and allow to dry OR physically remove laitence by suitable means
e.g. grinding, sweep blasting etc.
-
On previously painted concrete physically remove coating
by suitable means e.g. grinding, sweep blasting etc.
-
Steel : Blast with a suitable abrasive to near white
metal (SSPC 10/SA 2.5 standard).
-
If this is not possible remove loose material by
mechanical cleaning or high pressure water blast until only tight rust
is left.
-
Fibreglass: Abrade surface to give a good key.
-
All surfaces must be free of dust or other contaminants
before applying GEMCOAT ETC.
-
Aluminium: Abrade with non metallic abrasive or grinder
to give bright aluminum and a very good key ; coat within 1 hour.
