Penetrating Sealant for Landscape Stones: Wet Look, No Shine

Fist-sized river rocks along porch and trees. Want that "wet" look without gloss. Here's the pro system.

Two-Coat System

1. Sanding sealer (water-based) — penetrates, seals pores
2. Satin polyurethane varnish (water-based) — $30/gal, wet look, no shine

Heavy-Duty Option

Satin spar varnish (marine grade) — $40/gal, superior UV/moisture resistance.

Application

Dip stones or brush on. Work in shade. Two thin coats beat one thick. Recoat every 3–5 years.
