EaCo Chem Calcite Presoak Removal of Calcite

Calcite Presoak is designed as a pre-soak to facilitate the removal of calcite on clay brick (USE ON CLAY BRICK ONLY). Used in conjunction with NMD 80, this combination will ensure the complete removal of calcite.

First apply the Calcite Presoak undiluted and allow it to dwell on the surface for approximately five minutes. Repeat this process without rinsing until little pin holes have opened up. Then apply NMD 80 diluted four parts water to one part solution (4:1) without rinsing off the Calcite Presoak; allow a five to ten minute dwell time. Rinse completely to get the desired results.

Advantages

• Powerfully penetrates and softens calcite

Limitations

• May bleach surface if used repeatedly undiluted
• Do not use on lime-faced brick
• Only for use on clay brick
