Why M3C Mold?
Apply It and Walk Away
The wrong cleaner is how good hardscapes get ruined: acids etch natural stone, harsh mixes bleach color, and scrubbing the wrong chemistry just spreads the stain.

Apply It and Walk Away
Apply it and walk away: M3C breaks down mold, moss, mildew, lichen and algae at the root without pressure washing, scrubbing or rinsing. No bleach and no acid means it is safe across pavers, natural stone, walls, shingles, asphalt and wood, which makes it the one bottle that treats the whole shady side of a property.

Quick Answers
Will it hurt my pavers?
Used per the label on the listed surfaces, no. Always test a small hidden spot first; that one habit prevents almost every cleaning regret.
Do I have to pressure wash after?
Follow the label. Most SRW cleaners rinse with water; some work with no rinse at all.
Clean before sealing?
Always. Sealer locks in whatever it covers, so the wash is not optional if a seal coat is coming.
Is there anything I should know about handling it?
Wear gloves and eye protection, follow the label, and keep it away from children and pets until placed or cured. Full precautions are in the SDS below.
