Properties and advantages of redstone Sperrputz Secco 25kg

  The plaster withstands the corrosive effects of salts and frost, which increases its durability and effectiveness.
• High water pressure resistance
  With resistance to negative pressure up to 0.5 bar, equivalent to a 5-meter-high water column, it ensures reliable sealing.
• Easy application
  The plaster can be applied directly onto damp masonry, eliminating the need for extensive pre-treatments.
• Durable and maintenance-free
