BioAdvanced 2-in-1 Moss And Algae Killer
BioAdvanced 2-in-1 Moss and Algae Killer is designed for multiple outdoor surfaces, including patios and decks. It acts as both a moss killer and a cleaner, enabling removal of moss and algae on contact while helping prevent regrowth for months. The formula turns moss yellow and brown before you sweep or wash it away, which helps reduce bleeding and staining on pavers. This product is positioned as a versatile solution for homes with mixed outdoor surfaces.

This ready-to-spray product is formulated to kill moss quickly with a non-staining formula suitable for roofs, walks, decks, and patios. It is designed to avoid staining concrete, pavement, stucco, or wood, making it a convenient option for paver-adjacent areas where color consistency matters. Users typically see visible moss reduction in hours, with ongoing protection through subsequent rainfall and weather exposure.
Wet & Forget Moss, Mildew, Algae Stain Remover
Wet & Forget is a concentrate that cleans green and black stains from moss, mold, mildew, and algae without scrubbing, rinsing, or pressure washing. It works on a wide range of outdoor surfaces including driveways, patios, roofs, siding, decks, vinyl, wood, and concrete. The product is applied by mixing with water and spraying, then allowing weathering to remove stains. The approach emphasizes ease of use and long-term maintenance with periodic applications after rainfall.

This concentrate from Miller is designed to kill moss quickly with visible results in hours. Its non-staining formula can be used on roofs, walks, decks, and patios, making it a cost-efficient choice for larger areas or ongoing maintenance. Concentrates typically require dilution, which can extend coverage and reduce per-use cost while requiring careful measuring for proper effectiveness.
Buying Guide
- Surface compatibility: Confirm the product is suitable for pavers and concrete, and note any limitations with adjacent materials like wood or roofing ceramic. Some formulas are optimized for roofs and walls and may be gentle enough for pavers, while others are stronger and may cause staining if misapplied.
- Application type: Choose between ready-to-spray liquids for quick use and concentrates for larger jobs. Ready sprays are convenient but may be pricier per square foot, while concentrates offer better value for extensive patio areas.
- Time to results: Some products show effects within hours; others rely on weathering and may take days. If you want rapid improvement, look for fast-acting formulas specifically tested for moss on pavement.
- Staining risk and surface care: Many paver surfaces require low-stain formulations to preserve the appearance of the stone or sealant. Check product literature for staining warnings and test on a small area first.
- Environmental and pet safety: Review safety data for outdoor use near lawns and gardens. Some products require avoiding runoff into lawns or require waiting periods before pets return to the treated area.
- Coverage and dilution: For concentrates, estimate coverage based on label guidelines and your patio size. Proper dilution affects effectiveness and safety margins.
- Long-term control: Consider products that help prevent regrowth or protect surfaces from algae and mildew for months, reducing maintenance frequency.
- Allergen and surface interactions: If you have sensitive skin or nearby plants, prefer formulas with fewer irritants and consider rinsing or leaving undisturbed for the minimum recommended time as per label.
- Storage and disposal: Check storage requirements and disposal instructions, especially for concentrates and weather-dependent application windows.
When selecting a moss killer spray for pavers, balance immediate effectiveness with long-term maintenance goals, surface compatibility, and ease of use. Testing a small area first can prevent unexpected discoloration and ensure the product suits your specific patio or walkway material.
