Signs You Need Rust Stain Removal Interlock

Metal Objects – Furniture legs without protective caps, planters with metal components, decorative items left on surface, tools or equipment stored on pavers, nails screws or metal debris
Water Sources – Sprinkler system with high iron content, well water irrigation, runoff from rusting structures, condensation from AC units
Structural Sources – Rusting railings or fences, metal flashing runoff, deteriorating hardware, vehicle undercarriage rust

Why Rust Spreads on Interlock

Rust staining expands over time:

Chemical Process

  • Iron oxidizes when exposed to moisture
  • Oxidation products are water-soluble
  • Rain spreads rust across surface
  • Each wet cycle extends the stain

Contributing Factors

  • Paver porosity absorbs rust compounds
  • Textured surfaces trap deposits
  • Continued source contamination
  • Improper cleaning attempts

Why It Gets Worse

  • Initial spot becomes larger area
  • Light stains darken with repetition
  • Surface etching can occur
  • Stain penetrates deeper over time

When Stains Can't Be Fully Removed

Setting realistic expectations:

High Success Rate

  • Fresh stains (weeks old)
  • Surface-level discoloration
  • Light to moderate staining
  • Single-source contamination

Moderate Success

  • Older stains (months)
  • Deeper penetration
  • Repeated contamination
  • Heavy discoloration

Limited Improvement

  • Very old, deep stains
  • Etching has occurred
  • Paver material contains iron
  • Years of buildup

Alternative Solutions

  • Paver replacement for perfection
  • Stain integration with overall cleaning
  • Sealing to prevent worsening
  • Accept improved but not perfect result

Sealing After Rust Removal

Protection prevents recurrence:

Why Seal

  • Prevents new rust penetration
  • Makes future cleaning easier
  • Protects treatment investment
  • Addresses paver porosity

Timing

  • After complete stain removal
  • Surface fully dry
  • Before new contamination possible
  • Typically 24-48 hours after treatment

Sealer Selection

  • Penetrating sealers for natural look
  • Film-forming for enhanced protection
  • Joint-stabilizing options available
