• Good resistance to undercutting from damaged areas
• Overcoatable with most epoxy, acrylic or polyurethane coatings
• Use as a base coat for most thin film intumescent coatings

May be overcoated with itself or other products from the ViterShield, ViterSeal or ViterThane range.

Application

Blast clean to Sa2½ (ISO 8501-1:2007), surface profile 50-75 microns. All surfaces to be coated should be dry and cleaned as necessary to remove all oil, grease, salts, weld flux or other contamination. Where necessary, remove weld spatter and grind smooth all sharp edges and weld seams.

Apply via airless spray, conventional spray, brush or roller. Application by brush/roller will result in a reduced film thickness and is recommended only for small areas of touch up/remedial work.

If overcoating with Axalta ViterThane PLV or PLS, allow a minimum of 12 hours at 23°C when the primer has been applied to 100 microns DFT. Allow longer drying and overcoating times at higher DFT's and lower temperatures.
