Plaster & Surface Care

New plaster is highly sensitive during the first month of curing. Proper start-up protects the surface from etching, scaling, and discoloration.

What Happens During Curing

Plaster continues hydrating for 28 days. pH rises naturally, calcium can shift into the water, and the surface is vulnerable unless chemistry is managed.

Start-Up Guidelines

Fill without interruption to avoid fill rings. Adjust alkalinity first, then pH. Raise calcium hardness gradually. Brush twice daily for the first several days to remove plaster dust. Avoid wheeled cleaners until after 28 days.

Long-Term Care

Maintain an LSI between 0.0 and +0.3. Keep alkalinity, pH, chlorine, calcium hardness, and stabilizer within recommended ranges. Monitor the surface for early warning signs such as roughness, scale deposits, or uneven color.

Surface Warning Signs

Aggressive Water

Etching, pitting, plaster dust, uneven coloration.

Scaling

Rough deposits, heater scale, tile line build-up, salt cell scaling.
