Sukabumi Green Stone Maintenance Guide

Its moderate porosity resists algae better than highly porous stones, and algae resistance is further improved with a quality penetrating sealer applied at installation and reapplied per our maintenance schedule — unsealed stone in any material is more susceptible to organic growth.

As a dense volcanic stone, properly installed and maintained Sukabumi Green Stone commonly lasts multiple decades in outdoor and pool applications, with periodic resealing being the main maintenance requirement rather than structural replacement.

Yes — as an inert volcanic mineral it does not chemically react with standard pool chlorine or salt-chlorination systems, though we recommend a quality sealer to protect the surface from long-term mineral and chemical staining from splash-out.

Yes, we recommend sealing with a breathable penetrating sealer at installation and on a periodic maintenance schedule — this reduces staining, water absorption and algae susceptibility without trapping moisture in the stone.

Routine cleaning with a pH-neutral stone cleaner and soft brush is sufficient for most maintenance; avoid acidic cleaners (including undiluted vinegar or citrus-based products), which can etch the stone surface over time.

Yes, with care — use a moderate pressure setting and a wide fan nozzle held at a safe distance, since excessive pressure at close range can erode grout lines and, over repeated use, the stone surface itself.

A typical resealing interval is every 1-2 years for pool and high-exposure outdoor applications, though this varies with sealer quality, climate and traffic — our maintenance guide includes a simple water-bead test to check when resealing is due.

Algae buildup is typically caused by unsealed or under-sealed stone combined with persistent moisture and shade — regular cleaning and a properly maintained sealer coat are the most effective preventive measures.
