Sovereign Sulphate Resistant Ready Render 25kg

Sovereign Sulphate Resistant Ready Render is a pre-blended cement render designed to protect masonry and concrete in environments subject to sulphate attack. Supplied in a convenient 25kg bag, the ready-mixed formula combines sulphate-resisting Portland cement, washed sand and carefully graded additives to deliver a durable, consistent finish that is easy to apply on-site.

Key features and benefits

• Sulphate resistant: formulated to resist sulphate exposure in soils and groundwater, helping extend the life of rendered surfaces in aggressive environments.
• Ready to use: pre-blended with cement, sand and additives for consistent results on-site.
• Durable finish: designed to withstand weathering, damp and chemical exposure in rendered systems.
• Easy application: mix with water and apply by hand or spray, reducing on-site variability.
• Versatile use: suitable for internal and external rendering on new-build projects or remedial works.
