MasterSeal 550 

An acrylic reinforced cementitious, flexible waterproof coating

How does MasterSeal 550 work:

MasterSeal 550 is a two component acrylic modified cementitious coating that requires only on site mixing. Once mixed the product is applied by stiff brush, roller or trowel to form a waterproof, flexible protective coating. MasterSeal 550 provides an effective barrier to waterborne salts and atmospheric gases.

Fluid applied, MasterSeal 550 provides a hard wearing, seamless, waterproof membrane for roofs and foundation protection.

Where is MasterSeal 550 applied:

MasterSeal 550 is designed for use for the following applications:

• To reface and even out variations in concrete surfaces.
  
• As a waterproof lining for water retaining structures.
  
• For coating seawater channels.
  
• Sealing and coating tie bar holes to ensure watertightness.
  
• For waterproofing and protection against brackish water.
  
• To provide foundation protection.
  
• As a waterproof coating for roofs.
  
• As a backing to marble and granite to prevent tile adhesive mix water absorption and thus alleviate surface staining.
  
• To provide protection to concrete surfaces from carbonation and chloride attack.
  
• For use on pedestrian walkways in marine areas.
  

What are the advantages of MasterSeal 550:

MasterSeal 550 offers the following advantages:

• Waterproof
  
• Excellent adhesion.
  
• Bonds to porous and nonporous surfaces.
  
• Flexible.
  
• Non toxic suitable for contact with potable water.
  
• Suitable for light pedestrian traffic.
  
• Breathable - whilst repelling water, allows substrate to breathe.
  
• High resistance to chloride ion diffusion.
  
• Unlike conventional coatings which require a 7- 28 day cure of concrete, MasterSeal 550 can be applied to 24 hour-old concrete thereby giving immediate protection.
