Ensure the surface is thoroughly clean, dry and free from dust, grease, oil, mildew and other contaminants. All loose, peeling and flaking materials must be removed by sanding or wire brushing. Fill holes and cracks with a suitable filler. Finish sand the surface and remove all dust. Old glossy painted surfaces must be sanded to a dull finish before repainting. Mould-affected areas should be treated with a suitable product.
For new blackboards, apply one coat of undercoat paint and allow it to dry before over-coating with School Art Chalkboard Paint. For existing blackboards, wipe clean with mineral turpentine and leave to dry before
recoating with School Art Chalkboard Paint.
Stir thoroughly before use.
Apply two coats by brush, roller or spray.
