Paint Marble Crete

Project Scenario

Martha owns a fourplex in an old part of town. The siding is 4x8 sheets of pebbles. It seems the backing is concrete. Can she paint marble crete?

Preparation

  • Carefully pressure wash to remove airborne contaminants and weak subscrate.
  • Use mildew retardant solution if necessary. Rinse and let dry thoroughly.
  • Patch holes with caulk and stones, sized to match, pressed to the caulk.
  • For signs of moisture intrusion or water damage, spot prime with Z-Prime.

Primer Coat

If pebbles fall off easily, use Surfbond II Masonry Primer.

Best:      501801x Surfbond II Masonry Primer
Good:    501601x First Coat Primer

Top Coat

Best:      512301x pHlex-tite Elastomeric
Better:   510101x AC-909 Exterior Satin
Good:    52110xx AC-911 Exterior Flat

Caution! Things to consider

  • After pressure washing, rust stains may be visible. Use a spray can of Z-Prime to hide the blemish.
  • Back rolling the final coat will improve the appearance and ensure all portions of the substrate are coated.
