How does MasterEmaco T 545 and T 545HT work?

MasterEmaco T 545 is a one-component magnesium phosphate-based mortar. Offered in two formulations: T 545 for ambient and substrate temperatures below 85° F (29° C) and T 545HT for ambient and substrate temperatures ranging from 85 to 100° F (29 to 38° C).

Recommended uses:

• Interior and exterior
• Horizontal and formed vertical overhead repairs
• Applications requiring high early-strength gain
• Structural concrete repairs
• Partial and full-depth repairs
• Cold temperature repairs
• Grouting applications such as anchor bolts, rebar, dowel rods and precast applications

What are the unique features of MasterEmaco T 545 and T 545HT?

• Single component to just add water and mix
• Takes rubber tire traffic in 45 minutes
• Wide temperature use range from below freezing to hot weather exposures
• Air cure only, no wet curing compounds required
• Coefficient of thermal expansion similar to Portland cement concrete for more permanent repairs
• Higher sulfate resistance than conventional mortars

What are the benefits of MasterEmaco T 545 and T 545HT?

• Reaches 2,000 psi compressive strength in 1 hour to rapidly return repairs to service
• Very low drying shrinkage for improved bond to concrete for repair and anchoring applications
• Resistant to freeze/thaw cycles and deicing chemicals so it is usable in most environments
