Pro Tips

  • **Alkalinity Testing**: Test masonry pH before coating - high alkalinity can cause coating failure without proper primer.
  • **Efflorescence Treatment**: Remove all efflorescence and use appropriate blockers to prevent recurrence.
  • **Moisture Management**: Choose breathable coatings that allow vapor transmission while blocking liquid water.
  • **Surface Preparation**: Thorough cleaning is essential - remove all dirt, efflorescence, and loose material.
  • **Primer Selection**: Use masonry-specific primers designed for high alkalinity and porosity.
  • **Weather Timing**: Avoid coating in direct sunlight, high winds, or when rain is expected within 24 hours.
  • **Quality Investment**: Masonry coatings are long-term investments - use quality materials for best results.
