  • BREATHABLE MASONRY WATERPROOFING SEALER: This penetrating concrete sealer uses a polysiloxane formula to deeply permeate masonry surfaces, creating a breathable barrier that repels water, lets moisture escape, and helps prevent freeze-thaw damage
  • APPLY OVER OLD OUTDOOR STONE SEALER: Whether you’re using this as a concrete sealant or a brick waterproofing sealer, it works on previously treated surfaces sealed with water-based or solvent-based products to enhance water resistance & fix leaks
  • VERSATILE WATERPROOF SPRAY SEALER: Effective on multiple masonry surfaces, it can be used as a concrete waterproofer & cement sealer, or a brick wall & chimney sealant that can be used on both residential and commercial projects
  • 0 VOC CLEAR WATERPROOFING SEALANT: Our brick sealer dries to a non-glossy finish, preserving the natural look of masonry while providing superior water resistance; it won’t alter the surface appearance and meets strict air quality standards
  • EASY APPLICATION & CLEAN-UP: Apply this chimney waterproofing sealant with a brush, roller, or sprayer; each gallon covers 90-150 sq. ft. depending on surface porosity; cleanup is simple with soap and water
