Untreated surfaces should be prepared by blast cleaning to BS 7079:1989. Wire brushing may be acceptable where blast cleaning is not possible. Galvanised surfaces should be degreased before priming. Existing primed surfaces should be prepared by removing all
poorly adhering coatings, touched up as necessary with a suitable primer and checked for compatibility with Pyroplast-ST100.

Priming
The prepared steel surface must be primed with a suitable primer e.g.Pyroplast-ST120 primer. For advice on priming please contact Coatmaster.

Method of application
Pyroplast-ST100 may be applied by brush roller or airless spray:-
Brush: 600g/m2/coat
Roller: 400g/m2/coat
Airless Spray: 1400g/m2/coat

Drying
Pyroplast-ST100 is overcoatable in 8-12 hours depending on the application conditions. Pyroplast-ST100 must be thoroughly dry before coating with Pyroplast-ST120 top.

Maintenance
Minor mechanical damage may be repaired by removing the damaged coating back to a sound surface and applying fresh material by brush or roller.
