FOSROC Nitoseal® PU50: High-Performance Sealant for Construction Joints

In the construction industry, effective joint sealing is vital for maintaining structural integrity and preventing water ingress, chemical attacks, and mechanical stresses. While traditional sealants often fail in demanding conditions, Nitoseal® PU50 offers superior performance.

Features & Advantages of Nitoseal® PU50

• High Movement Accommodation: Handles up to 50% movement in joints up to 50mm wide, accommodating extreme situations.
• Damp Tolerant: Effective in sealing damp surfaces, preventing seepage.
• Robust Performance: UV resistant, non-shrinking, and non-staining for long-lasting results.
• Versatile Application: Ideal for concrete, brickwork, blockwork, precast panels, stone cladding, and perimeter sealing around doors and windows.
• Coatable Surface: Compatible with waterproofing and protective coatings.
• Fast Curing: Single component with a rapid rate of cure to expedite project timelines.

Surface Preparation Before Application

• Ensure all joint surfaces are clean, dry, and free from frost, dirt, laitance, loose material, and foreign matter.
• Remove rust, scale, and protective lacquers from metal surfaces through wire brushing, grinding, or grit blasting.
• For resealing, remove existing sealant and clean to sound concrete.
• Check expansion joint filler for tight packing; use bond breaker tape or back-up strip for control joints to avoid 3rd point adhesion.

Application

• Cut and remove the end of the sachet, place in a sealant gun, fit the nozzle, and cut at 45 degrees.
• Apply uniformly within the joint, ensuring full contact with the joint sides.
• Tooling should be done immediately after application for a smooth finish.
• Clean tools with Fosroc Equipment Cleaner or suitable solvent post-application.
